    Studie om framtagning av montageplaner: En granskning av monteringsprocessen för prefabricerat byggande2018Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Dagens industrier anpassar numera sin tillverkning för att kunna massproducera och dra ner på personal och kostnader. Detta innebär ökad automatisering med större och kraftigare maskiner, utrustning och verktyg. För att garantera säkerheten på arbetsplatsen är det därför viktigt att rätt skyddsanordning och myndighetskrav följs och används. I byggbranschen ställer arbetsmiljöverket krav på branschföretagen gällande arbetsmiljö och särskilda underlag för produktionsarbetet. Denna studie undersöker montageplanen som används vid industriellt byggande som innebär användning av tunga, prefabricerade, element vid husbyggnad.

    Syftet är att studera hur en montageplan planeras, upprättas och implementeras. Studien utförs på uppdrag av In3prenör och omfattar 10 veckors arbete. Författarna har tillhandahållits information kring montageplanen för två projekt som studerats jämsides. Det ena, ett pågående projekt, är Allégården som är ett ROT-projekt av ett vård- och omsorgsboende och det andra, projekt Arlanda, är en nybyggnation av en servicebyggnad. Metoder som använts för att uppnå resultatet har varit en kombination av litteraturstudier, granskning av montageplaner, platsbesök och intervjuer.

    Resultatet visar på att otydliga riktlinjer kring vad som ska inkluderas i montageplanen är det största skälet till att det blir fel på arbetsplatsen. Det har även från intervjuerna påpekats att på grund av den tidspressade situationen och målbilden att undgå förseningar kan det ske misstag som kan få allvarliga konsekvenser. För att förbättra kvaliteten i montageplanerna måste riktlinjer från arbetsmiljöverket och boverket bli tydligare gällande montageplanens innehåll. Det är också viktigt att kritiska moment som kan medföra ökade risker framgår i montageplanen, vidare kan montörer utbildas för att öka deras riskmedvetenhet.

    Objektklassificerad modellering och effektivisering avmängduttag2017Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The lack of fluent communication in the building industry has caught people’s attention because of

    time-based costs appearing in 2D and 3D modelling and takeoffs. These costs emerge in construction

    when miscommunication takes place between professionals in different projects.

    A research study of the subject has revealed the reason behind the current days’ miscommunication

    issues. The study shows that although the professionals tend to have an efficient way of working, the

    result isn’t very beneficial for the next man. Therefore a conclusion of the issue creates a demand for a

    mutual language in modelling and better softwares for takeoffs.

    This report’s results, with regards to optimization of modeling, has brought to light the use for the

    objectclassificationsystem BIP. These BIP-codes are used for branding objects in models of which the

    branding consists of unique codes. The code of every individual object has the purpose of being

    recognized by every project member and remain the same throughout the project.

    The proposal for the optimization of takeoffs is a software called VICO Office. The software contains

    well-advised methods for the import of models and close to automated takeoffs of these models.

    In conclusion, the study implies that there is sufficient motive to question the old ways of working and

    that light should be shed on new approaches. Technology and the industry face a constant change and

    the efficiency of current methods are never far away.

    En jämförelse mellan Tekla Structures och Civil 3D i krökta betongkonstruktioner2017Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Within the construction industry, there is a lot of discussion around BIM (Building InformationModelling). There is a need to move away from customized 2D-drawings and instead focus oninformative models which can be used throughout the whole cycle of construction. This developmenthas been ongoing within house construction, but this approach is harder to implement within thefacility sector.The difficulty in implementing a more BIM-oriented approach within construction is partly due tosoftware currently not being fully developed to create informative and reliable models of constructionswith complex geometries, such as bridges.Since Trafikverket, the largest construction developer within Sweden, has started to place a largerdemand on 3D there is a need for both technology and human resource to develop.The aim of this dissertation is to present a case study investigating the suitability of the software TeklaStructure and AutoCAD Civil 3D to perform a 3D-model of a double-curved bridge. The two pieces ofsoftware will be contrasted in a final comparison whereby both pros and cons will be presented.The study has made it clear that BIM is not just about creating an informative model, but it is alsoabout an approach which has the ability to completely change the construction sector to work morecollaboratively and effectively.The comparison between the two relevant software in this study shows that they both have strengthsand weaknesses and are suitable for our purpose. However, they differ in how detailed models theycan create and how well they have the ability to work with BIM to a greater extent.

    Samverkan av jord och ovanliggande struktur i FEM-program: En studie av nya jordmodeller I FE-programmet 3D- Structure2017Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    De senaste åren har det funnits olika företag som har tillverkat avancerade mjukvaror inom byggbranschen. En del av mjukvaror är avsedd att skapa 2D ritningar och 3D modeller. Med hjälp av dessa verktyg har ingenjörer och arkitekter snabbt och enkelt skapat ritningar och modeller för projektering av konstruktioner. Utvecklingen inom detta område kallas BIM. Byggnadsinformationsmodellering, BIM, stödjer design av en byggnad genom alla faser och möjliggör bättre konstruktions-, tillverknings- och inköpsaktiviteter.

    Andra mjukvaror är tilltänkt att förutse hur en struktur reagerar på verkliga laster, vibrationer, värme och andra fysiska effekter. För detta används finita elementmetod, där kommer strukturen analyseras i element för ett noggrannare resultat. En utveckling inom detta område har också skett. Företaget Strusoft AB utvecklar FE-verktyg för analys av struktur. Den senaste nyheten är modul för beräkning av samverkan mellan struktur, grundläggning och undergrunden i form av jord. Modulen kallas 3D-Soil och används enligt Strusoft för modellering och analys av geokonstruktioner.

    I denna rapport redovisas modellering av en struktur och underliggande jord med finit elementanalysprogrammet, FEM-Design som är försett med den nya modulen 3D-Soil för geotekniska beräkningar.

    Målet är att jämföra resultat för moment utifrån samverkanskrafter mellan jord och struktur i FEM-Design med ett annat FEM-program, Lusas. Till skillnad från FEM-Design appliceras jord- och vattentryck som utbredd last i Lusas.

    Resultaten visar att det finns signifikanta skillnader mellan resultaten från analysprogrammen och det finns begränsningar i modelleringsverktyget som behöver utvecklas vidare.

    Dimensionerande vattenförbrukning och dess variationer2014Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In Sweden, 2010, approximately 907 million cubic meters of drinking water was withdrawn from municipalities. All of this water must be transported, which is done through water pipes. To dimension these it requires that we know how much water that is to be distributed and it varies among others depending on the time of the day, week and year that the withdrawals occur. In today’s approach of designing new water pipes, amongst other ways, we use typical examples of consumption variations during the day of a similar area. In addition, arbitrary and experiential values of ‘ratio of peak hour to average day’ and ‘ratio of peak hour to average hour’ are used.

    Unfortunately today’s way of dimensioning water pipes has not been ensured due to inadequate detailed data on consumption quantity. The main purpose of this study is to confirm or refute today’s way of dimensioning water pipes.

    To verify this we have with detailed data from Norrvatten been able to see consumption quantity on an hourly basis which helps us assess today’s dimensioning process. By measuring the flow into 13 municipalities and then comparing them against each other regarding population size, distribution over categories of users and more, we have been able to get different dimensioning factors.

    In this report we can conclude that there is a need to update the factors regarding ‘ratio of peak hour to average day’ and ‘ratio of peak hour to average hour’. In order to further study the dimensioning factors, a system must be developed that can measure the precise consumer flow for different consumer categories on a more detailed level.

    Parameterstyrd projektering av broar: Koppling mellan Rhinoceros-Grasshopper och Tekla Structures2017Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    New methods for project designing in the building construction industry have been developed by introducing modern and powerful BIM tools. Several of today’s constructions are designed according to three-dimensional principles.Tekla Structures is a powerful BIM tool that is capable of managing both house and infrastructure constructions. Despite this, the program cannot handle bridges with a horizontal and vertical curvature efficiently. The designers must instead rely on several other applications to manage complex bridge constructions.In order to use the advantages of Tekla Structures, the software needs to be evolved or complimented by other third party softwares. This project aims to integrate new working technics and introduce a method based on parametric design in Tekla Structures. Such form of modeling enables the modification of parameters to a desired model for the user.A script is created through a visual programming extension that generates a parametric based bridge models. The bridge type in this project was designed, is an integral bridge.The project has proved that parametric based design is more effectively and a solution to manage bridges with horizontal and vertical curvature.

    Påbyggnad av bostäder på tak i Stockholm City: En möjlighet för att göra Stockholm City till en funktionsblandad och mer levande stadsdel2018Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Stockholm City is currently well composed in the aspect of commercial and public service. A consequence to this is a desolated City during the late night. A requirement to accomplish a more living inner city is a satisfying combination of functions whereas people are in motion between the home, work and other social activities. The main function missing today in City is habitats. A problem with supplying more accommodations in City is however the limited asset of ground area due to exploitation.

    In this thesis research is made whether it is possible to transform City into a mixed-function and thereby urban living area. With reference to the limited asset of ground area aswell as the opportunity to preserve the existing qualities that occupy these areas, a research is conducted for the purpose of more residential buildings with the method of expansion of existing buildings.

    The result of this thesis is a proposition for residential buildings on roof tops in City and the requirements for such project are being analyzed. The additional building is added to a specific building and by its shaping reflects a good residential environment and a design appropriate to the surrounding built-up area. The proposal consists of a rooftop landscape with eight pairs of houses. To insert accommodations throughout expansion of existing buildings generally is applicable in City and therefore an adequate solution to the problem considering the problems in the area.

It has not been shown to be appropriate to implement this on a specific issue or problem, when the available information deals with the theory and applications of partnering, not customer value.

    Given the above problem this papers purpose is to describe how the various contractors and clients, associated with partnering activities in Sweden, experiencing the work and factors that maximize customer value in a partnering project.

    A qualitative method where six people were interviewed, related to partnering activities in Sweden. The interviews are semi-structured and adapted to each interviewee.

    The most important conclusions that answer the purpose are:

     Understand the customers business

     Choose a form of compensation based on founded trust and project type

     All parties combined knowledge provides the right conditions for the customer to make the right decision

     Lack of common well-developed digital tools

     Make decisions at the right time

     Reference Surfaces and own final checks instead third party inspector

    Möjligheter och utmaningar med internationella inköp: En studie av internationella inköp2017Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The construction industry in Sweden today are facing a major challenge in building society and following the pace of population growth. Rising material prices are today a fact, and at the same time there is a lack of capacity at the Swedish suppliers as they are bound up in supplier agreements for the coming years. The largest construction companies in Sweden have been working strategically with international suppliers for a long time to increase their margins and to secure their material needs.

    BTH Bygg AB is today a company that builds, renovates and maintains real estate in Stockholm. The company has expanded in recent years and is committed to strong growth by 2020. Work on international purchasing has previously been limited to BTH Bygg, but this type of purchase is today seen as a necessity to continued growth and to be competitive in that part of Sweden where most is built.

    The purpose of this study is to analyze BTH Bygg's existing purchasing process to further develop and propose improvements with international procurement as a starting point.

    The study has been conducted with the help of interviews to get a complete picture of the issues of international purchasing. BTH Bygg AB has a strong organization with a lot of experience related to the subject area, and focus has been on compiling these in order to come up with suggestions and ideas on how to handle international purchases. Recommendations are focused on areas related to supplier assessment, communication, logistics and product selection.

    Renovering av miljonprogrammet: Ur ett ägarperspektiv2012Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Apartment buildings built between the years 1961-1975, also known as ”miljonprogrammet”, are in need of extensive renovations. The need for renovations stems from wear and tear, but it is also due to a lack of maintenance work. The renovations costs for these areas are often enormous. In addition to wear and tear, the need for renovations are due to the technical condition of the house, but also because of stricter governmental requirements, high energy consumption, social factors, higher demands and a need for modern apartments. The government has been clear with its intentions not to contribute financially to the renovations and improvements of miljonprogrammet. This means that decision makers in real estate companies will soon have to make a verdict concerning the need for renovations and make concrete decision on how the apartments are to be renovated. There are good opportunities for renovations of miljonprogrammet, but the opportunities are often limited by the property owners’ and the tenants’ economic capabilities, and building- and governmental requirements.

    This study will highlight what needs, opportunities, and limitations are put on owners and managers of properties when it comes to renovations of miljonprogrammet.

    Questions:

    • What controls the owner’s decision concerning possible renovations?
    • What controls the owner’s decision concerning extent of possible renovations?
    • What is the owner’s view on the different forms of contracts between owner and entrepreneur concerning procurement of renovations contracts?

    Open interviews with property owners have shown that property owners’ decisions concerning a possible renovation of miljonprogrammet are largely controlled by the properties technical condition. Prerequisites for renovation vary depending on property area and property market. This has significance in terms of opportunities for financing the need for renovation through raise in rent. Concerning the extent of renovations, the property owners want a reasonable economic cost with profit and returns in five to ten years. This is limited by governmental requirements, rules, and decisions that in certain cases can lead to the property owner being forced to reduce measures, demolish houses, sell the houses, or not put in an effort at all.

    It seems normal for property owners to choose a form of contract with regards to the resources and knowledge found in the company. When choosing a form of contract, the property owners prefer to contract out the totality of the renovations when it concerns larger properties because there are many unforeseen moments in a renovation contract. The property owners also want to split up the renovations in several stages to promote continued cooperation with entrepreneurs and to force the entrepreneurs to do their best to go on to later stages of the renovations. The forms of compensation considered to be most suitable are either fixed price or fixed price with incentive. It is considered important to incentivize or give a carrot to the entrepreneur for committed work. The choice of entrepreneur is controlled by several factors because of the complexity of renovating a property.

    Requirements put on entrepreneur:

    • Committed organization
    • Competent organization
    • References of similar projects
    • Economic strength
    • Experience of work with tenants

    Abstract [en]

    To safely and effectively carry through within the construction industry, planning plays an important part. Work preparation is one form of planning. When using the model of work preparations, one analyzes the specific work preparation with the intent and goal to carry through the labor within the beforehand estimated time, budget and quality, while still maintaining satisfying work environment.The aim of this paper is to, from a perspective of work environment, map out how NCC: s work preparations function today. The goal is to provide suggestions for improvement. This can be done by performing interviews and surveys on the NCC employees.The results indicate that the staff of NCC see work preparation as a helping aid in improving work environment. However, there are also shortcomings in the way work preparations are done at NCC, and these could be improved. We therefore recommend NCC to make improvements in the planning, realization and the follow-up phase when setting up a work preparation. Our suggestions for improvement can be found under “recommendations”.

    Samverkan arkitektur och installationer: Osynligt ventilationssystem i utställningssal på Plan 4, Nationalmuseum2013Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This degree project has been carried out in collaboration with the National Property Board of Sweden. The National Museum is currently undergoing renovation where the goal is to restore the building to its original glory. A new ventilation system is to be installed to facilitate a stable indoor climate for the conservation of museum artifacts. The building has been declared a historical monument which imposes limitations on permissible alterations to its architecture and construction. The degree project examines how to combine these limitations with the demands made on the ventilation system by answering the following question, "How can modern installations be integrated within a historical monument, without affecting the historical value?" To exemplify the complexity of this problem, a section of the building has been chosen and studied in more detail. A principle solution is then presented where the installations are integrated with the surrounding structures.

    The air supply to the exhibition halls on the fourth floor constitutes one of the more complex problems in the building. The installations that service these halls are to be contained within the floor structure above. It is this floor structure that has been studied in more detail. The museum climate and its effects on the artifacts, building construction and installations are studied in depth. Currently the museum environment is a heated topic of discussion where prescribed guidelines are challenged and an international standard is sought. The desired indoor climate determines the scope of the ventilation system. Therefore this report concludes a discussion on the climate requirements presented by the National Museum and how these can be accommodated.

    Our conclusion is that a sustainable integration of architecture and installations can be achieved when the solution is based on the limitations of the building as opposed to the demands of the occupants.

    Abstract [en]

    This report investigates the possibilities of using residual products as sound insulation in apartment

    separating timber floors with a span of 6 m. One step towards meeting the Swedish construction

    industry's zero vision for carbon dioxide emissions is to build more using timber and to reuse/recycle

    residual products. The Swedish building contractor Skanska has at its quarries a surplus of material in

    the form of crushed rock of the 0 - 0.2 mm fraction and crushed residual concrete. In this report, a

    prototype of a timber floor has been produced with influences of construction technology from the

    turn of the 19

    th century regarding the use of heavy filling as sound insulation in timber floors.

    The developed floor prototype complies with the requirements set in BBR after dimensioning

    according the Eurocodes regarding fire safety, strength, sagging and deflection. According to a

    simulation in SEAWood, a tool for acoustic simulation which is under development at RISE Research

    Institutes of Sweden the requirements for sound insulation are also met, which is supported by

    analyzes made by comparing with data on similar timber floors. The high mass of the filling material

    implies that the prototype is a low frequency floor, this in conjunction with the simulation only being

    an indication of sound insulation properties, it will require practical tests to determine the prototypes

    sound insulating and dynamic properties.

    The developed floor prototype is suitable for prefabrication thanks to a design with few components.

    Prefabrication of the floor has in addition to the economic benefits it brings great benefits from a

    working environment perspective and is also beneficial from a moisture point of view.

    To estimate the environmental impact of the timber flooring, a simple comparison was made with a

    prefabricated concrete floor which showed that carbon dioxide emissions up to the using phase were

    more than twice that of the concrete floor than for the prototype floor.

    Klimatkalkylering2014Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This is a study on the climate impacts associated with the construction of railway bridges in order to develop key performance indicators such as operation, material and amounts to effectively reduce greenhouse gas emissions. The basis of the study has been work in Trafikverkets tool klimatkalkyl 2.0. It has been reviewed on the basis of ease of use and accuracy of input data and emission conversion factors. That’s because we wanted to see the difference between the model and a unique project. What was different and why?

    This study has concluded that without some care and work in klimatkalkyl 2.0 is a risk of incorrect results. In addition the study demonstrated questionable defaults for significant items. In addition to these results the study found that the most significant parts of the unique projects emissions is reducing the amount of steel and concrete and to find suppliers who can demonstrate low emission factors. With relatively simple measures could the unique projects total carbon emissions be reduced by almost 20%

    Optimering av den svenska metoden fördimensionering av betongbeläggningar på flygfält2017Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Sverige har länge använt beläggningsytor av asfalt på grund av dess flexibla

    egenskaper som är lämpliga för det svenska klimatet. Historiskt sett har Sverige

    haft låg trafikmängd vilket inte gett utrymme för utvecklingen av betong som

    beläggning i vägar.

    Trafikmängden har sedan ett par år tillbaka ökat markant och det kan därför hända

    att det kommer att byggas betongvägar i huvudleder. Emellertid är erfarenheten i

    Sverige så pass låg att utveckling av nuvarande metoder fordras. USA har länge

    brukat betongvägar i stor skala och har betydligt större mängd betongvägar i

    motsats till Sverige, som har mindre än 1 %. Den ökade trafikmängden speglas

    även på flygplatser.

    I den här studien jämförs den svenska dimensioneringsmetoden för

    betongbeläggning på flygfält (Strand, 2016) med den amerikanska

    dimensioneringsmetoden i syfte att optimera den svenska metoden.

    Den svenska dimensioneringsmetoden (Strand, 2016) som denna studie behandlar

    är förenklad och baserad på gamla teorier. Metoden framställs genom äldre

    litteraturstudier men kombineras även med aktuell litteratur. Den amerikanska

    metoden används genom dess egna datorprogram kallad FAARFIELD där alla

    beräkningar görs med hänsyn till dess normer och krav.

    Dimensioneringen sker för lasten från Airbus A380 med 365 avgångar per år

    enligt Swedavias förväntningar. Oarmerade betongplattor med 350 till 450 mm

    tjocklek med betongkvaliteten C35/45 klarar inte av utmattningskriteriet. Däremot

    klarar likadana plattor med betongkvalitén C60/75 utmattningskraven och

    fungerar utmärkt som beläggning på uppställningsplatser och rullbana. Vid

    dimensionering enligt den amerikanska metoden visar resultaten att plattorna blir

    både tjockare och tunnare än den svenska metoden beroende på vilken

    betongkvalite som används.

    Den svenska metoden förutsätter en del förenklingar vid dimensionering av

    betongbeläggningar och därför blir inte beräkningen helt korrekt. Resultaten som

    denna studie visar är därför preliminära. Optimering av den svenska

    beräkningsgången är ett steg i rätt riktning men det praktiska utförandet av arbetet

    och erfarenheten av detta är något som måste byggas ut för en fulländad och

    fungerande metod i praktiken.

    Klassifikationssystemens påverkan på kalkylarbete: En jämförelse mellan CoClass och BSAB-systemen2018Independent thesis Basic level (university diploma), 180 HE creditsStudent thesis
    Abstract [en]

    As the construction industry shifts to digital information modeling of its projects, the need to coordinate and improve the efficiency of the management of this information increases. A common language in the form of an industry-wide classification system could lead to billions in savings annually. In the calculation, it is important that the correct information management is included in order to provide the most accurate calculation possible.

    The aim of this study is to examine how the three different systems, BSAB 83, BSAB 96 and CoClass, differ and stand in contrast to each other to highlight and demonstrate such differences. The purpose of the study is that it should be used as a basis for how ÅF can create classified calculations with CoClass.

    To achieve the aim of the report and answer the research questions, the examination consisted of literature studies, interviews, a comparative study and a case study. These methods contributed to the following result: ÅF could effectively transfer to the CoClass system. When comparing the systems, it has been shown that CoClass is a more extensive and comprehensive system structured in a different way as opposed to the previous classification systems.

    Based on the results of the study, a calculation structure according to CoClass can be implemented in ÅF's current working methods, where ready-made recipe for building components can still be used. The recommendation is to consider the component table as equivalent to the production result in the calculation work with CoClass structure in the MAP. In the long run, this would have been an efficient strategy, both economically and primarily less time-consuming.

    Ett bostadshus i prefabricerad trästomme: Ett gestaltningsarbete anpassat efter volymelementsbyggande2014Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This report is a compilation of the planning of a 5-storey residential building. The building in question has been designed to be built entirely in a wooden frame mainly consisting of a modular building system. Modules also referred to as prefabricated volume elements are room units that have been constructed through industrial means. These room units can be developed enough to be delivered with complete facades or even fixtures. Since the planning of the residential building has been made based on a modular building system, adaptations to the project has had to been made as to accommodate necessary requirements. A practical example of this is how the apartment plan has been affected based on laws concerning the maximum amount of allowed width/height during transportation on public roads. These laws control the size of how big volume elements can become and as a result the apartment layout.

    The report consists of a study into the area of industrial wood construction, but foremost it treats the practical challenges and possibilities that have surfaced as a consequence of planning residential housing based on a modular basis.

    Abstract [en]

    There is a housing shortage in Stockholm and the most vulnerable group are young people who are tryingto establish themselves on the housing market. The lack of housing opportunities is forcing students towait for many years before they get a chance to rent a home and thus contributes to withdrawal fromstudies. The establishment of new student-housing is growing but there is still much progress to bemade until the needs are fully satisfied. At the same time office spaces are left vacant with no tenantswaiting to move in. Stockholm is growing at an increasingly high pace and establishing new housing is aninescapable truth. Furthermore, tearing down existing buildings can cause a strain on the environmentwhereas preserving existing buildings can contribute with cultural value and befriend sustainability.Although the intended use of a building isn’t always suitable for its layout. In this instance, changing thepurpose can contribute to the preservation of a building and at the same time fulfil the needs originatingfrom the shortage of housing.This degree project within the Bachelor programme in Construction Engineering at the Royal Institute ofTechnology in Stockholm, has been performed at Ahlsénarkitekterna during 10 weeks. This thesis treatsthe subject of the adaptive reuse of existing office buildings into student housing.

    Tids- och kostnadseffektivisera byggproduktionen: Slöserier och störningar2018Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The biggest challenge construction companies are facing at the moment is reducing the unnecessary costs and labor as well as to streamline the work. This is a matter and an investigation that has been done multiple times in recent years because this is a major problem in most construction companies. This report is commissioned by Peab for the purpose of identifying wastes and critical disorders, then drafting action proposals to reduce waste of time and costs.

    Four different, completed construction projects have been investigated, commissioned by Peab, and are located in Stockholm. These projects include the reconstruction of a roadway intersection and new construction of pedestrian and cycle tracks. These four projects vary in scale, giving a more varied result compared to four very similar projects

    The gathering of information for this work has mostly included

    lean construction with the various waste in the work industry, as well as the different principles and methods of lean construction, such as Just-In-Time. Other studies on the construction process have also been made, more specifically the production phase, the planning of the work. The difference between value creation time and non-value creation time has been dealt with, as well as risk management and how to conduct a risk analysis.

    Interviews have also been conducted with the aim of identifying the most critical wastes and interferences.

    The gathering of facts from the interviews has been reported in the results.

    It emerged that the four most critical wastes were defects/rework, waiting, transportation and extra processing. In summary, action proposals using lean construction, interviews and the knowledge from this report have been developed to reduce these disturbances and wastages with help of for example Jidoka and PDCA to increase time and cost efficiency in the production process.

    In short, the concept of waste and disturbance can be defined differently. Waste is an activity that does not contribute anything to the business, and a disturbance is a matter of disturbing the work.

    Effektivisera implementering av BIM i produktionen: En studie om vad som krävs för att underlätta implementering av digitala verktyg i produktionen2018Independent thesis Basic level (university diploma), 5 credits / 7,5 HE creditsStudent thesis
    Abstract [en]

    The general mode of operation within the building and construction sector in the present days are classified as outdated with plenty of room for improvement. Fortunately, this has been picked up by more organizations and has enabled them to spot the future of the work procedures in digitalisation. This has now been put on the agenda of implementation within the organisations as it has proven to be more efficient not to mention profitable.

    BIM (Building Information Modeling) is today frequently used within projection but the main question remains, the question on “how to implement BIM to the production”. The evolutionary curve within projection is exponentially increasing and at the same time, the vision of a more digital driven production process within the building sector is becoming more of a reality.

    This report is mainly based on field studies in which the building sector often touches the underlying factors on the implementation of digital tools. The focus area lies within the production stage of which many studies show that there is in fact an existence of good knowledge of digitalisation and resources within the branch to apply it to the steamline in order to achieve increased efficiency. However, the process of advancement is being pulled back by the human factor in terms of the individual ́s limited knowledge of digitalisation, the willingness and fear of change and also the generation gap.

    The Final result is based on fact collection, surveys, construction exhibitions and interviews with experienced workers in the targeted field. Study visit has been arranged to SWECO Civil AB and other companies with the similar qualifications. The advantages of implementing digital tools to the day- to-day work are considered to be many. Performing work tasks using for example an ipad will result in a simplified workday in the terms that one will be able to navigate and store required data much more efficiently than before. The process will become less time consuming and with the focus now directed to what is more important, it will result in an improvement of the overall quality. In the long term the aboves mentioned measure is equivalent to a more competitive and profitable organisation.

    Inneklimat i kontorsmiljö: Utvärdering av inneklimat i en kontorsmiljö med fokus på ventilationen2018Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In today's society, humans spend about 90 percent of their time indoors, in an artificial indoor climate. As people tend to be indoors more and more, it is important that the ventilation work as well and efficiently as possible, and that the indoor climate is pleasing for our well-being at the workplace. Previous studies show that almost half of Swedes are dissatisfied with the ventilation in their work environment (offices).

    A good indoor climate in offices increases employee satisfaction, increases productivity, and reduces absenteeism. This causes the organization / company to save money in the end, as staff work more efficiently and have less sick leave.

    The purpose of this study is to investigate the climate in office environment, focusing on thermal comfort and to see how ventilation systems affect the indoor climate. Furthermore, the relationships between these will be analyzed. The aim is to investigate how the comfort in the office affects human health, productivity and well-being. The goal is also to identify if there is insufficient ventilation to the offices that will be investigated and to eventually present possible improvements.

    In this report a study of six offices on Brinellvägen 23 was carried out. In the study, a number of flow measurements are carried out for each office's supply and exhaust air, carbon dioxide measurements, temperature and the relative humidity for four hours in four of the offices, with open and closed doors. While in two of the offices, the measurements continued for a whole working day, 6-8h.

    In addition to these measurements, surveys were distributed to the staff in the offices in order to share subjective opinions about the environment in the offices.

    The results from the measurements and the survey showed that the overall climate was not satisfactory, and discomfort was experienced by the people working there. Only one office met the projected supply airflow, while the remaining offices neither met the projected flows nor BBR requirements for the amount of flow in office environments. The carbon dioxide levels in the offices with one person was acceptable, they did not pass the limit of 1000 ppm. However, the offices were projected for two persons and when two persons worked in the offices, the carbon dioxide levels exceeded about 1200 ppm. When the carbon dioxide level exceeds 1000 ppm, it is recommended that the ventilation be checked, as needed in this case.

    Co-rotational planar beam element with generalized elasto-plastic hinges2017In: Engineering structures, ISSN 0141-0296, E-ISSN 1873-7323, Vol. 151, p. 188-205Article in journal (Refereed)
    Abstract [en]

    Slender elements in framed structures may undergo large displacement and experience highly nonlinear behavior. This paper presents a two-node co-rotational flexible beam with generalized elasto-plastic hinges at the beam ends. A Condensation procedure is used to remove the internal degrees of freedom so that the formulation is easily incorporated with the standard co-rotational approach. A family of asymmetric and convex yield surfaces of super-elliptic shape is considered for the plastic behavior of the hinges. By varying the roundness factor, an infinite number of yield surfaces are obtained making it possible to select the yield function that best fit experimental data of any type of cross-section and material. The nonlinear response of bolted connections subjected to both bending and axial forces are conveniently modeled with such a yield surface. Discrete constitutive equations for the hinge plastic deformations are derived using the implicit scheme for both smooth and non-smooth cases. Numerical examples demonstrate the accuracy of the model in predicting the large displacement inelastic response of framed structures. Effect of the roundness factor on the ultimate load strongly depends on the structure typology. It was observed that cyclic loading produces pinching effect, cyclic softening and ductile behavior. Those effects are more pronounced with anisotropic yield criteria.

    Energieffektivisering genom ombyggnad: Med hjälp av VIP-Energy2013Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This degree project has been written in collaboration with Värmex AB, with the generous help of Anders Ericsson as our fellow adviser and Peter Hansson (Sweco) our mentor from the Royal institute of technology located in Haninge.  

    Today we find questions pertaining to energy consumption in apartment blocks of real significance; with each building project a declaration that shows the amount of energy consumed is of outmost importance. We strive to reduce energy consumption in apartment blocks by 50 % until year 2050. In this degree thesis, we aim to describe measures and solutions to lower the consumption of energy in a specific apartment block located in Nacka, Stockholm.  

    This building has been standing quite untouched and unmarked since 1949, yet it is still in compliance with the demands stated by BBR concerning energy efficiency, in large because of its climate shell. Sources show that greater parts of its outer shell for example the front, should have been repaired during the first 30 years, and the matter is still to be solved.

    The use of a computer software VIP-Energy has enabled us to state a hypothesis. With the help of public documents from Housing And Urban Development Town Building Office (HUD) giving us an overview of the different dimensions of the building, we've been able to plot all this data into the software. Information such as building materials, location, heating systems have also been necessary in our analysis. Results are automatically compared to the demands required by BBR. It is through experimentation of this data that we have been successful in collecting our results. 

    In the analysis, we chose to focus on the climate shell that constitutes: roof, floors, walls, windows and doors. Our results show that lower U-values conduce better energy efficiency.

    Studies show that almost 35 % of energy loss in a building is caused by the windows of the building, this this is consistent with the building which this analysis is based on.

    We have solved this by changing sheet glass that is energy efficient. We also aim to change the frame and seams surrounding the windows, in order to lower transmission losses and possible draughts in the apartments. This will result in hopefully a higher degree of comfort and refreshing atmosphere. The same changes apply to entry doors in order to keep energy loss to a minimum. Also an external insulation in the outer wall contributes to improvements on u-value and use.

     The original building shows an average U-value of 0,656W/m2K and the energy consumption is 96 kWh/m2 per year. According to BBR, older buildings should have a U-value of 0,400W/m2K and an energy consumption of 90kWh/m2 per year. Energy balance calculation show new values for the building were the u -value should be set to 0,409W/m2K, and energy consumption should be set to 64kWh/m2.

    Abstract [en]

    Quality is the key to a well executed product or service. The construction industry hasn’t highlighted the quality in recent times which have contributed to the construction industry receiving much criticism in the field. The public sees it as an offhanded industry where errors and delays are common.The reason for this is considered to be primarily the lack of time, constant pressure to reduce costs and skills and the ability to communicate between the parties about what the correct quality really means. The industry has begun to realize that it must start setting clearer standards and that there are great opportunities for improvement.This report will give Peab an opportunity to develop their quality work. The report highlights Peab residential area of Stockholm market position with the current quality of subcontractors and suppliers. It also provides suggestions on how Peab in a better way can work with quality and with this becoming a more competitive player in the market. The conclusions that can be drawn from this study is that Peab is aware of the problem and has begun work on improvements to enhance quality of work. Peab, for example, developed tools for gathering experience. Unfortunately these methods were used poorly and not to the degree that is required. Peab also works with partnering, based on long term business relationships. Correct use of partnering increases the chances of higher quality in the projects. Concrete proposals for improvements that this report highlights include higher standards in the procurement process, dare make demands on the quality of subcontractors and suppliers, learn from the mistakes made and disseminate the knowledge within the Group and work with long-term business relationships in which partners can develop one another .

    Abstract [en]

    In this report, we have explained the problems that may occur with today's technology and what possible solutions to improve with time. With the help of the Swedish Transport Administration, we have implemented this thesis.

    We got the clear directions from the Swedish Transport Administration regarding purpose of this thesis. This made it easy for us to delineate our work after the guideline that was definer.

    The study's purpose was to try to understand why you can´t give out the relevant traffic information. Today we have the technology create a well smooth operation system. A system where you can easily get real-time information related to traffic, road works and obstructions.

    In this report we have summarized all the navigation system that you could use as a road user. We have done an analysis of how other countries give out their traffic information and how good they are against the Swedish traffic information system.

    For our thesis we have used various of different reports and interviews. The interviews have been with people who have knowledge in the field. We have also used numerous websites to gather information.

    Recommendations for the thesis will be described through five themes. In this report, we have conducted a variety of interviews that we have compiled for themes. Themes were designed for what we felt was most relevant from the interviews. Our themes are a mirror image of what we thought was the most relevant part in our thesis.

    Kommunala särkrav på byggnaders tekniska egenskaper2012Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Starting in 2003 JM has gradually been implementing measures to streamline its enterprise by means of increased standardization. The measures have resulted in increased quality and lowered costs.

    In order for the organization to be successful it is necessary that the same building codes are enforced in all municipalities in a certain part of the country, as is intended. Local building codes that differ from the national ones have negative consequences for JM in the form of additional costs and longer times for planning and construction, because the benefits of a standardized business model are lost.

    In November of 2011 the Swedish Ministry of Health and Social Affairs was tasked with presenting proposals on how the building industry in Sweden can be improved. Emanating from that inquiry, this thesis examines the occurrence of local building codes regarding energy provisions and consumption. Moreover, the effects that local building codes have on JM have been analyzed.

    The responses to a questionnaire that was sent to around twenty municipalities in Stockholm County show that several municipalities have local building codes with stricter requirements than the national codes. An analysis of these stricter local building codes shows that they have significant effects on JM.

    Local building codes that differ from the national ones have negative consequences in the form of additional costs for JM and longer times for planning and construction, because the benefits of a standardized business model are lost.

    The municipalities, most likely, have good intentions when they decide to implement stricter local building codes. Unfortunately, these intentions collide with the JM:s standardized way of building and one adverse consequence may be a decrease of the quality of the constructions. To avoid this it is important that the same building codes are enforced in different municipalities.

    Boverket has a responsibility to review its regulations and look at the possibility to introduce a national system of classifying building codes whereby the municipalities may choose to enforce stricter codes in a standardized manner.

    Samverkan på Järnvägen: Samverkan för arbete med Förebyggande Underhåll2013Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    During the writers literature study they received a clearer perception of the problematics that is embossed in the Railway industry. Several larger reorganisations had created an industry with unclear responsibilities and unclear roles resulting in several protracted litigations between the client and the contractor. The mood was described as bleak and compromises between the operators did not occur by the necessary means, the operators mostly considered only their own activities in the industry. A change had to be done.

    This report is limited to three key operators with connections to the maintenance on the railway. These key operators are: the client, the contractor and the transport operator. The report focuses on the all too reoccurring corrective maintenance those results in traffic-disturbances and traffic-stops. In the same time an insight occurred that a large need for implementing a preventive maintenance on a larger scale existed. Considering the knowledge the writers had acquired during their education about preventive maintenance, it slightly shocked them to see how the railway maintenance was carried out on the railway.

    Different operators in different organisations on the railway are dependant of each other to accomplish a functional railway, thus an increased interaction between the operators is achievable. Dialogue and interaction were two keywords that often reoccurred and the idea to, by an increased dialogue, introduce routines for an extended interaction was considered being a first step to solving the issues that exists on the railway.

    During the writers work on this report, they discovered that the railway industry is an industry under renewal. A process for improvement is currently going on, in the form of purer roles which was carried on after a decision was made by the Parliament of Sweden. The Forum for Accessibility (FFF) is a forum, which had their first meeting in April this year, they are currently working on increasing the interaction on the railway. In this forum the client, contractors and transport operators form a dialogue to achieve this increased interaction between one and another.

    A lot has happened during the writers work on this report and they have developed an interaction-strategy in the best way possible to make this strategy applicable considering the current conditions on the railway today.

    En modern projekteringsprocess: Utveckling av en effektiv arbetsmetod för konstruktörer vid projektering med BIM-verktyg2013Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The development of BIM has in recent years gained momentum and many countries, including Sweden, have begun a process towards common structure in the sector of construction by standardizing information and processes (Nilsson, 2013). This development provides new opportunities for participants in the process of construction but also problems when the intensive IT- development meets a seemingly conservative industry (Statskontoret, 2009:6). The aim of this thesis is to design a modernized working process for the structural engineer that integrates BIM tools in the design process. An understanding of how the constructional engineer's work looks today is determined, and the possibilities and difficulties that the designer is experiencing.

    The findings in this study were that, despite the intensive development of BIM in recent years traditional processes are still applied, since an understanding of a higher initial effort does not yet exist. Increased demands are also put on the structural engineer's technical competence in structural engineering since it´s harder to "cheat" in the object-based models. The qualitative study demonstrated a conservative approach where the development of the structural engineer's role by means such as finished components from different vendors in Tekla Structures was seen as more problematic than beneficial. It also emerged that the most effort should be in the coordination of the project, in which more than clash detector tests should be taken into consideration and that the review should take place at an earlier stage and performed more consistently. In the practical use of Tekla Structures several opportunities to review and coordinate a project was found. The need for standardized BIM as concretized in the theory section was also confirmed by the respondents in terms of the desire for a common structure in the models.

    The work resulted in a working model for how the structural engineer should work with BIM and the conditions requested to allow this approach. An important part of this is to define a well-structured and clear way of working that is achieved through clear goals. Central to each BIM project is to appoint a BIM Coordinator whose task is following up the work towards the defined goals and ensuring united design among the workers. BIM requires a comprehensive understanding of the design to meet the new requirements.

    Kvalitetssäkring av 3D-modeller i Revit2017Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    At present, BIM (Building Information Model) is used in a vast majority of large scale building projects. A 3D model is created with a compatible BIM program. By working on a 3D model, the work process simplifies due to the fact that all users can simultaneously work on the same model, thus providing better coordination capabilities and delivering an overview of the final product.

    As a structural engineer, it is important to have an accurate and reliable basis for working with precision data. Currently, Sweco has no documentation which offers clarification or quality assurance to the content of 3D models. With this in mind, there is a considerable opportunity for improvement by using a checklist to advance the quality assurance of modeling to a new level.

    The task involved the creation of a checklist that could enhance the working process and improve quality assurance regarding the creation of a 3D model. Through interviews with constructors at Sweco, a checklist was created that will be effective in use by constructors working with Revit, as there are currently no comparable documents available. The conclusion that can be drawn from this work is that the drafted checklist is a positive step towards a better controlled modeling process of 3D models.

    Internationella inköp av prefabricerade stomelement: En studie om möjligheterna och svårigheterna vid import2014Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The construction material market in Sweden is considered today to be oligopolistic where few companies dominate the market. New ways of procuring materials could increase the competition and change the terms for all the actors. Studies have shown that import is one of those new ways of procuring materials, thus altering the current price structure. But companies that consider importing materials will face problems that need solving.

    The company Midroc has shown great interest in investigating the possibility for purchasing precast concrete structural elements from overseas. The main purpose of this report is to investigate the possibilities of importing and evaluating potential suppliers.

    Through interviews, literature and inquiries to sales managers and local suppliers, important factors have been identified, such as standards, warranties, transportation and financial risk. A significant finding was that there are technical standards that differ between countries which can impede import. One way to surpass this is to look for concrete products which are certified with the BBC mark.

    A questionnaire was made which was meant to give useful information about what the company offers and how they work. Price was not included due to the fact that the main interest was the circumstances around an international purchase. However, it has emerged that concrete structural elements in the Baltic States could be 20-30 % cheaper than Swedish products.

    Suppliers in Poland and the Baltic states were phoned and e-mailed. The suppliers that answered were all currently working in Sweden and interested in increasing their export. A supplier assessment was made which is based on the answers.

    The fact that all companies were currently cooperating with construction companies in Sweden, show that they are familiar with Swedish regulations and often are able to offer an overall solution. This indicates that the possibilities of importing precast concrete elements to Sweden are good.

    Trädetaljer i exteriör arkitektur: En rapport om hur arkitekturen kan tillåtas framhäva trä som byggnadsmaterial i utvalda exteriöra detaljer för ett äldreboende med massiv trästomme2014Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Architect firm Kolman X Boye Architects has been commissioned to execute permit documents for a senior housing. It has not yet been determined in detail how the building will be built, but client wants the building to be constructed in timber engineering . The senior housing is projected to accommodate 54 apartments spread over six floors and a total floor space of just under 6000m2. No equally high wooden building with this fire classification has previously been constructed in Sweden.

    Our task and challenge of this work has been to explain the known problems with exterior design of details in tall timber buildings. Based on the known issues regarding fire safety, acoustics and moisture have a number of details that affect the aesthetic expression been projected. Detailed solutions including terrace floor, facade systems and balconies have been projected. The goal was to allow wood to be seen in the architecture as far as this has been possible with regard to local rules and regulations.

    Our projected draft detailed solutions demonstrate the ability for wood to be a visible part of the architecture even for a building of this volume and fire activity class. Our work also shows how the known problems with fire, acoustic and moisture associated with wood construction can be avoided. Our proposals in detail solutions can form the basis for further planning and preparation of construction documents for this senior housing in Norsborg.

    Läckor på PE-ledningar: Statistiksammanställning & analys2014Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The most common material used when producing new water pipes in Sweden in 2008 was polyethylene. A couple of pipe owners in Sweden discovered that pipes made out of PE who only had been operating a few years broke, despite the fact they are supposed to have a service life of 150 years. The pipe owners therefore created an organization named 4S with the target to develop the PE pipe system. The problem was that the organization did not know how widespread the problem with leaking PE pipes was and they only had indications of why it is caused.

    The objective with this project was to collect statistics to show how widespread the problem is and to find where and why the problem arises.

    A couple of question that described to the pipe owners what kind of data that was needed, on order to make a good examination, was put together and sent out. The data that came in was put together in an Excel document to get a better picture of the problem.

    The results that came in proved to have major flaws and it was difficult to draw statistically based conclusions. The results, however, showed a hint that the problem mainly was in the joints and in smaller dimensions. The biggest problem was that the received data most often was either inadequate or non-existent, and the pipe owners have to work harder improving the system. The statistics also cannot find any age related problem.

    Energianalys mellan programmen IES (Integrated Environmental Solutions) och Enorm2010Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    An increase interest of new methods and tools has begun to grow in the real estate business, this new trend causes an increase in new programs that aim to simplify processes of energy-efficiency and environmental issues.

    After consulting with Björn Alsmark from Bjerking AB, an architect and engineering company, we made a decision that the Degree Project is going to examine the program IES (Integrated Environmental Solutions) with some integrations from Revit Architecture application.

    To be able to examine IES, we got access to a completed project from Bjerking. The project is a nursery school in Uppsala. An application has been handed in from Bjerking to make this project to a Green Building-certificated project. According to Bjerking own calculations (with the energy-calculation program Enorm), the consumption of energy of the nursery school is 48 percent lesser than required by BBR.

    An evaluation of IES and Enorm has been made with an aim to compare these two programs and find out if IES is an appropriate program to replace Enorm. Does Enorm or IES come up to BBR´s recommendations?

    The Degree Project cover 15 ECT, that required several adjusting and delimitations, and the study sketch ended with a literature study.

    After finishing the study sketch the modeling of the nursery school began. The model was adjusted in Revit Architecture so that it would suit IES. But complications appeared when the Revit model was about to be transferred into IES. Instead of using Revit, we simplified the model by using IES own modeling application, ModelIT.

    A study of the sun was made in SunCast to be able to get a study of the suns solar shading on the building, also the sun effect. The result from SunCast was later used in the energy-calculation in ApacheSim. A ventilation scheme was also designed in ApHVAC.

    The result showed that the IES VE is suitable for energy modeling and that there is space for improvement over the integration between the IES VE and Revit.

    Bultförstärkning av berg vid konventionell tunneldrivning: En jämförelse av kamstålsbult och PC-bult2018Independent thesis Basic level (university diploma), 5 credits / 7,5 HE creditsStudent thesis
    Abstract [en]

    The conventional rebar bolt, a grouted bolt with no pre-stress, is the most commonly used rock reinforcement bolt for tunneling in Swedish infrastructural projects. The assembly takes place by manually pushing the bolt into a borehole filled with grout. This gives rise to spillage and great physical exertion when thousands of bolts are mounted in each project.   Permanent safety is only achieved when the surrounding cement has cured. This entails a moment in the rock reinforcement stage where the contractor must secure the tunnel with temporary operating bolts.  To avoid temporary bolting, a pre-stressed bolt can be used as a permanent bolt. An example of such a bolt is the PC-bolt. When assembled, it provides immediate operational safety and permanent reinforcement by injection through the inner pipe. The bolt is then completely sealed with grout.  The purpose of the study is to compare the PC-bolt with the rebar bolt. The study explores the supposed benefit of economics and load ergonomics of using the PC-bolt as a permanent reinforcement bolt. By conducting a controlled observation on a field study to a site where tunneling with rock reinforcement occurred. The assembly of the two bolts has been compared out of a load ergonomic view point. In order to investigate differences in work volume and time, calculations were made on a compiled bolt protocol. The calculations show which reinforcement bolt results in the lowest cost of the assembly.  The result of the study shows that there is a great potential in the future use of the PC-bolt as a permanent bolt for tunneling. The potential lies in a clearly improved work environment regarding ergonomic loads and more time efficient installation that can be utilized in future projects.

    Produktivitetsmätning i anläggningsprojekt: Ett sätt att optimera framdriften2018Independent thesis Basic level (university diploma), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Skanska (2016) har uppgett som ett av sina mål att minska slöserier och stillestånd i produktion. För att nå dit har Skanska tagit fram en metod för att mäta produktiviteten för sina anläggningsprojekt. Skanska köper maskintjänster för ca 1 miljard kronor per år. Undersökningar har visat att maskiner står stilla 30 till 40 % av den planerade arbetstiden. En dag av stillastående arbete är kostsam och om det gick att effektivisera med endast 1 % sparar det Skanska upp till 10 miljoner SEK per år.

    Tillsammans med Skanskas region Väg och Anläggning Mellansverige, utfördes mätningar på fyra av regionens projekt med hjälp av en produktivitetsmätare som fästs på grävmaskinernas bom. Produktivitetsmätaren kan inte koppla rörelser till effektivitet utan räknar endast rörelserna maskinerna utför.

    Målet med rapporten var att hitta samband mellan driftnedgångar och aktiviteter i produktion samt att se varför de uppstår, för att senare ge förslag på hur de kan förebyggas eller åtgärdas. Ett annat relevant slutresultat var att lägga grunden för fortsatta mätningar och kontinuerlig uppföljning. Studien genomfördes med metoderna mätningar, dagböcker och intervjuer.

    Resultatet blev att driftnedgångar uppstår på grund av:

    • ●  Brist på material

    • ●  Krockar i arbetsmoment

    • ●  Arbetsplanering

    • ●  Bristfälliga handlingar

    • ●  Brist på yrkesarbetare

    • ●  Väntetider

      Optimeringen av arbetet kan ske redan i planeringsfasen. Grunden till en bra produktion ligger i hur välplanerat projektet är. Att bibehålla en god kundrelation i produktionsskedet underlättar till att snabbare få tag på kompletterande handlingar. Genom att involvera produktionspersonalen i planering, kan risken minska för att onödiga stillestånd uppstår. Deras kunskaper och erfarenhet om arbetets utförande är värdefulla i planeringen. Även att skapa leveransplaner för material och en levande arbetsplatsdisposition, där materiallager uppdateras kontinuerligt efter tidplanen och kommande arbetsmoment. Mätdata från produktivitetsmätaren kan i framtiden användas för att skapa diskussion i alla led. Som en punkt vid veckomöten i produktion, som en punkt i ledningsgruppsmöten i distriktet och även för Skanska centralt. Detta för att ta lärdom av varandras sätt att arbeta.

    Kan trämaterialet DDW ersätta stål vid konstruktion av framtida gång- och cykel broar: Jämförelse utifrån LCC2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    n this thesis a comparison is made between two different construction materials based on LCC for pedestrian and cycle bridges. These materials are steel and Delignified Densified Wood (DDW).

    Today ́s society needs to develop with more sustainable and climate-friendly construction. This need imposes demands on the Swedish transport administration, e.g. that building materials need to be developed. One viable material for Sweden, since it has good access to forestry and wood production, is wood. The Swedish transport administration should use more of the potential of wood. This study therefore assesses DDW, which is a wood-based material, based on interviews and life cycle cost analysis (LCC-analysis).

    LCC is a way of getting a complete picture of a product's entire costs during its lifespan. In the case of a bridge, the costs are estimated from planning to demolition. The purpose of LCC analysis is to find the most profitable investment cost that meets today's social requirements.

    DDW is developed by researchers at Maryland University. Researchers have observed that natural wood can be as strong as steel. The process involves removing lignin and placing it under pressure at a temperature of about 100 ° C. This causes the cellulosic fibers to compress and become harder. This simply means that the wood becomes much harder, more durable and stronger, and can also shape and bend.

    The result of the thesis suggests that DDW is not suitable at present as construction material in outdoor climate and is not economically profitable. DDW is scientifically interesting and should be researched further.

    Abstract [en]

    As cities become denser, population increases and the build rate today for elementary schools is low,more and more students will need a place in schools that are not yet built. Today, temporary modulesare a solution to the school shortage, these modules come with the risk of being used for a longerperiods than was planned due to the lack in planning for permanent schools. At the same time alreadyexisting elementary schools, in particular, the inner cities ones face another problem, that of a limitedplayground.The aim of this work is to design a permanent elementary school that will fit in an inner cityenvironment and, despite its limited amount of space, will be able to achieve the recommended keyfigures for playgrounds outdoors. In order to design such a primary school, investigations were carriedout in the form of literature studies, web searches, personal interviews and personal visits at variouselementary schools. The interviews were conducted in person with specialists in the planning ofelementary schools, with primary school teachers and with experienced architects and constructorswith substantial knowledge in their fields. Based on the investigations, a primary school wasdeveloped which works in an inner city environment.The elementary school was designed with regard to internal and external noise and has a flexibledesign to be adapted to sites with different conditions. The building has a limited space that offersenough playgrounds for the students in the form of balconies, roof terrace and a playground in theground floor beneath a part of the building standing on pillars. We believe that this solution to aprimary school can in the long run be a good start for reducing the shortcomings of schools facing oursociety.

    Abstract [en]

    Ricksattra 1:1 is a real estate of 42 hectare placed in Ekero. In the year 2010 the real estate got a new owner with new ambitions. But with limited time in disposal the new owner couldn’t exploit the real estate and bring forward the development to what is needed. Today the real estate is barely used and its full potential is not meet. The client has now entered a new phase where he wishes to meet that potential by building a modern society with growing opportunities and energy-saving buildings. Future thoughts of development are already in the clients mind. He wishes to build among others a preschool, mustering point, parks, stores and different types of residential buildings with the passive house concept. There are very high opinions of Ricksattra, and that rightly so. There are desires to build a society with a large growing capacity and with a hallmark of modernism and environment friendliness aspects, which in the future will be highly valued. As a county Ekero is expected to put great emphasis on this region, because a fully developed Ricksattra will give a raising value on the city, this in turn will develop a positive reputation. 

    The work is aimed at projecting residential building on a specific selected area where illustrations of apartment buildings along with neighboring parks and streets will be designed. By getting this formally in writing and design, this report could be the starting point for Ricksattra’s development. The emphasis will be on the customer’s requirements and he wishes the result will lead to, with some adaption to the limits of my education
