    Building maintenance strategies: planning under uncertainty2012In: Property Management, ISSN 0263-7472, E-ISSN 1758-731X, Vol. 30, no 1, p. 1-15Article in journal (Refereed)
    Abstract [en]

    Purpose:

    The article critically evaluates maintenance strategies and analyses the extent to which models

    from other sectors can be applied to building maintenance.

    Design/methodology/approach

    The paper is of a theoretical nature and is based on a number of Swedish case studies and

    questionnaires from which a number of stylized facts have been identified. These have then been

    used to explain and draw conclusions on maintenance strategies.

    Findings

    The main finding is that there are a number of specific uncertainties that affect building

    maintenance planning, which makes detailed long term plans less meaningful. The paper proposes

    a new structure for maintenance that focuses on long term goals for various buildings/components

    and then short run adjustments when new information is acquired.

    Research limitations/implications:

    The case for the new model needs to be strengthened by further studies including some from other

    countries.

    Practical and social implications

    Maintenance activities will become more important as the need to renovate or demolish the large

    building stock from the 50s and 60s increases. A rational structure and realistic expectations

    concerning maintenance planning are therefore important.

    Originality/value

    The most important contribution of the article is to underline the importance of different types of

    uncertainty for the structure of building maintenance planning.

    Critical reflections on the concept of maintenance2012In: International Journal of Strategic Property Management, ISSN 1648-715X, E-ISSN 1648-9179, Vol. 16, no 2, p. 105-114Article in journal (Refereed)
    Abstract [en]

    The purpose of the paper is to critically evaluate the conceptual distinction between investment and maintenance. The study starts from a number of definitions in the literature and discusses these from the perspective of standard investment theory. The article argues that the standard concept of investment covers all relevant decisions and also puts the focus on the future consequences of decision and not whether it restores an earlier standard or not. The research implications are that investment and maintenance planning need to be analysed together and that the distinction between investment and maintenance is uninteresting from a decision theoretic and resource allocation perspective. The practical implications of the article are that what usually is called investment planning and maintenance planning need to be integrated. The originality in the paper lies primarily in the questioning of the usefulness of the concept of maintenance in a dynamic age where the relation to earlier characteristics and functions becomes less and less interesting. The role of the maintenance concept is now primarily related to various administrative systems (accounting, taxation) but is not so relevant from a forward looking resource allocation perspective.

    Challenges in property management within the Swedish cooperative housing sector2016Report (Other academic)
    Abstract [en]

    Purpose - The paper investigates the challenges to property management in the tenant-owner cooperative (TOC) housing sector in Sweden which accounts for 22% of the housing stock in the country as compared to an average of 10% in the rest of Europe.

    Design/methodology/approach - A qualitative descriptive approach is used in the paper in which semi-structured interviews of governing committee members in 12 TOCs; a questionnaire on operation and management strategies sent to chairpersons in 725 TOCs as well as a questionnaire on issues related to energy efficiency sent to chairpersons in 91 TOCs provide the empirical data. This is complemented by an analysis of financial reports.

    Findings – The paper provides indications that most of the challenges identified are related to the lack of a long-term perspective in the decision-making due to various principal-agent related problems. There appears to be an exploitation of the TOC sector by construction companies especially in cooperatives with newly constructed buildings.

    Research limitations/implications – Because of the chosen sampling method and research approach, the presented results may lack generalisability. Thus, researchers are encouraged to carry out further studies.

    Practical implications - The paper highlights the need for knowledge sharing as well as enhancement of competence in procuring outsourced services.

    Originality/value – This paper fulfils the need for more research into the large but rarely studied TOC sector governed by amateurs in property management.

    Managing special purpose properties: A study of practices in the public sector organisations and private manufacturing companies in Sweden2011Conference paper (Other academic)
    Abstract [en]

    Purpose The purpose of this study is to analyse strategies used by state and county government organisations as well as private sector manufacturing companies in Sweden with the aim of identifying factors that can lead to more efficient management of special purpose properties in view of limited access to capital or government funding partly due to the global economic recession.

    Design/methodology/approach –The study is approached using a web-based questionnaire to solicit responses on issues such as decisions concerning securing of availability of production space, operating and maintenance strategies used as well as prediction of future actions. A total of sixty nine requests sent to property managers and company directors produced forty completed questionnaires that formed a database for the descriptive analysis.

    Findings The findings indicate that there is a high degree of special property ownership in the surveyed companies despite changes in the market and that the probability of an expansion of the property leasing market in the coming five years is low. Companies in the Swedish public sector could benefit from increased outsourcing so as to focus more on core business. They could also benefit from seeing over policies concerning responsibilities and liabilities in the premises they lease so as to make them clearer. The results also reveal an urgent need towards a more uniform definition of concepts and classification of activities in all of the categories in the study. The level of neglected maintenance is deemed as higher in the public sector especially in the counties in contrast to private manufacturing companies that according to the study adhere more to long term maintenance plans.

    Originality/value The key study results are of use in other countries that are considering privatisation or sale-leaseback transactions of large property portfolios under government ownership and provide new insights on the strategic maintenance of the properties in relation to the question of neglected maintenance.

    Organizational Challenges in the Adoption of Building Applied Photovoltaics in the Swedish Tenant-Owner Housing Sector2015In: Sustainability, E-ISSN 2071-1050, Vol. 7, no 4, p. 3637-3664Article in journal (Refereed)
    Abstract [en]

    Sweden has committed itself to comply with EU-directive 2009/28/EC on energy from renewable sources and 2012/27/EU on improvement in the efficiency of energy. Measures in the existing housing stock, such as installing photovoltaics (PV), provide a means of contributing to the goals above. The purpose of this paper is to study how the organization of property management and the decision-making structure in tenant-owner cooperatives (TOCs) in Sweden facilitates or hampers the adoption of large-scale residential building applied photovoltaics (BAPV) in this housing sector. Data collected through seven semi-structured interviews of executive board members in seven housing cooperatives were descriptively analyzed and the results indicate that the decision to adopt BAPV in TOCs does not follow the common frameworks of adoption of innovations. The choice by TOCs to adopt BAPV depends more on the wish to lower operating costs than on efforts to promote a sustainable environment and various principal-agency problems during the decision-making process, as well as during the implementation phase create challenges to the adoption of BAPV. There is a need to strengthen the quality and management of knowledge, as well as procurement proficiency in the TOCs in order to harness the potential for BAPV in the sector.

    Property Maintenance: Concepts and determinants2009Licentiate thesis, monograph (Other academic)
    Abstract [en]

    Introduction

    Strategic property management aims at balancing the question of how the needed space is to be secured, maintained, increased or disposed of in a cost effective manner under a mixture of decisions and actions. In recent years, the interest in building maintenance has increased as more and more of the housing stock built after the Second World War is in need of major renovation.  For example, approximately 1 million dwellings were constructed in Sweden in the period 1960-1970. Currently there is growing concern about the expected huge cost of maintaining this aging housing stock especially in the portfolio under municipal ownership. Private housing companies have been shown to report lower maintenance costs than those in the public sector but which are the factors that can explain the apparent differences? During the last decade there has also been a growing trend of governments diversifying themselves of their properties and/or outsourcing the property management. A question of interest is whether it is advantageous to do so and if the maintenance management differs substantially between the government sector and the industrial sector which is seen as business oriented and with a production centred maintenance strategy. In a number of industries there has been a paradigm shift in maintenance whereby the focus is no longer only on availability but reliability and cost effectiveness. New maintenance strategies and policies such as reliability centred maintenance have seen the light of day though without winning ground within property management. Shouldn’t building maintenance be handled in the same way?

    This licentiate thesis focuses on the strategic management of housing properties under public and private ownership as well as the management of special purpose properties in the government and industrial sectors in relation to the ongoing discussion about neglected maintenance. The purpose is to contribute to the process of cost efficient and effective maintenance both in the housing sector and in the management of special purpose properties through underscoring the factors that lead to differences in the maintenance levels in the different categories.

    Method

    The questions above are analysed through a theoretical part that discusses the concept of maintenance and strategies in building maintenance in relation to other industries. The thesis also contains an empirical part that is based on a survey in the form of a questionnaire on housing maintenance and an econometric analysis of the maintenance costs contained in the financial reports of the municipal and private housing companies as well as a questionnaire on among others how state and county governments as well as industrial companies have secured the availability and management of their special purpose properties.

    The thesis consists of four papers the first two of which are co-authored with Hans Lind. It starts by demarcating the concept of maintenance in the context of standard investment theory followed in paper 2 by a discussion of the term “maintenance strategy” and some stylized facts concerning building maintenance in Sweden. Maintenance strategies and approaches used in some other industries are presented as a background to an analysis of why building maintenance is different. The various factors that affect the maintenance costs reported within the housing sector are surveyed and analysed in paper 3 before the results from a survey on management of special purpose properties in the state and county governments as well industry sector are presented in paper 4. A questionnaire was used to get a broader material about aspects that were difficult to observe directly, including views about underlying factors.

    Results

    From the perspective of investment theory everything that is usually classified as maintenance is also an investment. The concept of maintenance can in a number of situations be taken to be unnecessary. A review of strategies from other industries reveals a focus on systematic data collection and cost analysis before action is taken and a move away from time scheduled maintenance to acting on the condition of the object. However building maintenance contains a substantial degree of corrective maintenance with a high degree of opportunistic maintenance and detailed maintenance planning is not ideal due to constantly changing needs and demands. An important result is from the surveys and econometric analysis which indicate that the ownership category has a significant effect of approx. 35 per cent on the maintenance costs reported by the housing companies. Furthermore a major factor affecting the cost level in the housing companies is the influence of external factors such as pressure from the media and politicians. The degree of special property ownership in the surveyed companies is high and the probability of the leasing market increasing in the coming five years is very low. According to the respondents there is very little neglected maintenance in the industry in contrast to the government sector especially in the counties. Furthermore, the maintenance plans in the public sector were shorter than those in the private sector.

    Discussion

    The outstanding result from the surveys is that classification of activities as maintenance or investments in both housing and special purpose properties differs in that the public sector companies lean more towards maintenance than investment in their accounting and have a higher degree of adherence to laid maintenance plans. The distinct difference in the pay-back duration used by the government sector as compared to that in the industry sector in effect lowers the effectiveness of the government sector as the lower required rate of return allows the government sector to have more activities that appear to be profitable.  Maybe the problem to worry about should not be that of neglected maintenance in this sector but that of unprofitable maintenance that should not be carried out. This might also just explain why more activities are classified and dealt with as investments by the industry and not by the county or state companies or the municipal housing companies.

    Conclusion

    There are strong arguments for saying that building maintenance rationally differs from the kind of maintenance and maintenance planning that could be observed in some of the other industries and the concept of maintenance is much more suitable in a world where there are smaller changes and where it is believed to be possible to know long in advance what is rational to do. The divergence in classification of activities even within the same category and company revealed by the two surveys is problematic as it complicates comparison of activities and services provided as well as benchmarking and it should be given appropriate attention by the managers. This goes to show the great need to use the same well defined concepts in order to benchmark and develop more efficient maintenance management strategies.

    Future research

    Though each building is unique the goal should be to develop a model that is rational given the specific uncertainties that characterise a building and the institutional system in which decisions are made. The limited size of the sample and the lack of transparency and uniformity in the financial reports constrain the research efforts in this study. However research is needed towards a clearer and more transparent classification of maintenance activities with the purpose of not only reducing the gap between the reported maintenance costs of the companies but also increasing the comparability in the branch. This will help to isolate and possibly limit the external influence in the management of the companies especially in the municipal housing sector.

    Property management and maintenance in the multifamily housing sector in Sweden2016Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Several studies and government reports have indicated that a large number of apartments in Sweden built during the 1960s and 1970s require extensive refurbishment and that there is concern that some companies in the rental housing sector and in the tenant-owner cooperative (TOC) sector may have difficulties carrying out the needed activities. The overall purpose of the thesis is to increase the understanding of the factors that influence the decisions made within the multi­ faceted property management of multifamily housing in Sweden which would mitigate some of the shortcomings. Econometric analysis and semi-structured interviews as well as questionnaires carried out within the TOC sector as well as the public and the private rental housing sectors provide the basis of the conclusions arrived at. The aim is to contribute to raising efficiency in maintenance and property management within the housing sector in Sweden. The major conclusions presented in the thesis are that: maintenance as a concept is unnecessary from a decision-making perspective as the concept of investment embraces all the relevant decisions; maintenance models in manufacturing industries could be applied within the housing sector but building maintenance is different and should be grounded on a strategy that allows for the continuous adjustment of maintenance plans based on a regularly up-to-date decision support system in the company or TOC; reported maintenance costs within the municipal (public) and the private rental sectors in Sweden continuously diverge mainly due to principal-agency issues of a socio-political character, in the form of political involvement in the operations of public housing companies, as well as the way companies define maintenance together with the timing of the maintenance measures; hidden incentives in the form of cooperative members, managers or service providers that seek short term gains together with the lack of a long-term perspective in the decision-making as well as a high turnover rate of committee members are major challenges to efficient property management within the Swedish TOC sector. Similarly, the information asymmetry between the professionals (constructors as well as service providers) and the amateur decision-makers in the managing committees, especially in cooperatives with newly constructed buildings, is a substantial source of losses in efficiency within the operations of the TOCs. Major contributions of the thesis are that: it promotes the view of maintenance as an investment and highlights the possibility of cost saving through the linking together of several measures as well as the challenges involved; it points to the need within the housing sector for better decision support tools as well as knowledge transfer and sharing; it calls for the government to promote policies that would reduce the degree of information asymmetry between the procurers of services within the TOC sector and the construction companies as well as other service providers. A requirement of formal competence and certification could be a step towards increasing the degree of qualified decision making and efficiency in property management within the housing sector. How this could be implemented nationwide in the different housing sectors is an issue worth further investigation.

    Underhållsplanering hos Trafikverket: Effektmodeller och pedagogiskt redovisning av motiv - En förstudie2010Report (Other academic)
    Abstract [sv]

    Sammanfattning

    För perioden 2010-2021 har riksdag och regering anvisat en planeringsram på 136 miljarder kronor för drift och underhåll av statliga vägar där det största verksamhetsområdet underhåll av belagd väg omsätter omkring 3 miljarder kronor årligen. I underlaget till nationell plan för vägtransportsystem (NPVS) äskas en högre summa på grund av eftersatt vägunderhåll.

    Denna studie fokuserar på att genom intervjuer och en enkätundersökning klarlägga prioriteringsgrunder för den tilldelade medel och hur informationen bakom besluten har samlats och dokumenterats.

    Resultaten visar att projektledare beläggning har bra kännedom om sina områden men det är kunskap som inte alltid är dokumenterade på ett tillgängligt sätt för andra i organisationen. Dessutom saknas det enhetlighet över landet i dokumentation av erfarenhet och av åtgärderna. Eftersläpande underhåll definieras av en majoritet av projektledare som "att alla vägar inte uppnår en bestämd målstandard" men om det fastställd målstandard i regionen eller beläggningsområde eller något annat är inte tydligt blir det svårt att bestämma storleken på eftersläpande underhåll. Samhällsekonomiska bedömningar är implicit i beslut om underhåll men undersökningen inte har kunnat fastställa att någon samlad effektmodell används av projektledarna i underhållsplanering utöver den individuella erfarenhetsbanken. Prioritering mellan att göra en större åtgärd istället för att fortsätta låga och lappa bygger delvis på önskemål samt på en strävan att samordna aktiviteter för att budgeten ska räcka så långt som möjligt. Befintliga avancerade verktyg i PMS används inte och en majoritet av projektledare håller sig med enklare Excel dokument och diagram i sin dokumentation av kunskap om vägtillståndet.

    En slutsats är att innan en diskussion om optimal underhållsnivå tar vid, borde mer fokus läggas på redovisning av vad den befintliga anslag har använts till och hur prioriteringen har gått till samt att försöka förstå vilka implicita effektmodeller som används. Först därefter går det att bedöma vad ytterligare resurser skull leda till för insatser och vilka samhälleliga effekter som skulle uppstå.

    Under överskådlig tid kommer inte heltäckande vetenskapligt underbyggda effektmodeller att vara tillgänglig. Den lokala kunskapen är viktig och frågan är om inte en mer decentraliserade underhållsplanering borde accepteras. Tonvikten i styrningen blir då mer att kräva en mer utförlig dokumentation om planerings- och prioriterings kriterium för att kunna följer upp arbetet. För att man på centralnivå ska ha koll på att det görs "rätt" i regionerna behövs det tydliga riktlinjer om vilken information som ska samlas in för att behålla tillsyn, så att det sen kan föras en dialog mellan ledning och lokala enheter Idag är mycket av arbetet individbetonat vilket framgår av att till och med projektledare inom samma region har olika uppfattningar om rutiner och strategier.

    Enligt vår mening är ett intressant nästa steg för att utveckla underhållsplaneringen att genom "deltagande observation" försöka fånga upp och kodifiera hur erfarna projektledare tänker. Detta projekt skulle kunna genomföras som ett kombinerat tekniskt/ekonomiskt projekt eftersom båda typerna av kompetens behövs för att förstå tankeprocesser och beslutskriterier. Implicita effektmodeller kan identifieras och steg för steg göras mer explicita och underbyggda. Hypotesen är dock att det alltid kommer att finnas "lokal kunskap" och erfarenheter av hur komplexa objekt är som går utöver effektmodellerna och att systemet för underhållsplanering måste göra det möjligt att kombinera utvecklade effektmodeller med denna lokala kunskap. Genom att utnyttja projektledarnas Excel kunskaper kan t ex en enkel LCC kalkyl modell utvecklas till att visa effekter av olika åtgärder som scenarion i planeringsarbetet. Idag bygger beslut på subjektiva beskrivningar som i sig är grundat på erfarenhet men svåra att redovisa. En enkel beslutsmodell baserat på några få parametrar i Excel skulle t ex ge ökade transparens av prioritering av åtgärder inom en given budget och därefter på ett pedagogiskt sätt visa konsekvenserna av att inte få det medel som äskas.

    Analysis of factors influencing reported housing maintenance costs in Sweden’s public and private rental sectors2017In: International Journal of Strategic Property Management, ISSN 1648-715X, E-ISSN 1648-9179, Vol. 21, no 3, p. 284-295Article in journal (Refereed)
    Abstract [en]

    The reported maintenance costs per unit area within the public rental housing sector in Sweden are consistently higher than those within the private rental sector. This paper uses crosssectional panel data analysis as well as a questionnaire survey sent to 196 managers in the private and public housing sectors to identify the factors that might explain this divergence. The findings indicate that fundamental factors such as the age of the houses or the composition of the tenants cannot explain the observed difference. However how the activities are classified and the timing of the measures are factors that can. The conclusions from the study are that the public companies should act more as the private sector in their accounting; wait longer than they currently do before carrying out some renovations; and that they should be more stringent when determining the resources to spend on large-scale maintenance and/or renovation projects.

    Lessons in community owned PV from swedish multi-family housing cooperatives2015In: 31st European Photovoltaic Solar Energy Conference and Exhibition, 2015, p. 2745-2750Conference paper (Refereed)
    Abstract [en]

    With increasing population shifts to urban areas and demands for post-war energy efficient renovationsacross Europe, solar photovoltaic (PV) deployment in multi-family housing will play an increasingly important roletowards meeting renewable energy, climate, and sustainability goals. This paper describes the stories of threeSwedish residential cooperatives who have installed large-scale PV systems across multiple buildings on their estates.In all cases, reduced operating costs were the original primary motivator; however unforeseen cost increases, changesin policy, and excess supply in the electricity market have made economic success less likely than originallyexpected. Regardless, the owners consider their projects a success due in part to short term social and long-termenvironmental benefits, which were originally less important and difficult to quantify. We can conclude thatcommunity owned PV offers more than just economic benefits, and Sweden’s unique ownership and managementstructure of residential cooperatives can offer insights towards increased deployment in other nations in Europe.

    Photovoltaic Systems for Swedish Prosumers: A technical and economic analysis focused on cooperative multi-family housing2016Report (Other academic)
    Abstract [en]

    This report is designed to be a comprehensive information resource for Swedish prosumers considering an investment in solar PV systems. The target audience are multi-family cooperative houses, however much of the information is applicable to other building owners and solar energy more broadly. The primary question to be answered; is a rooftop PV investment profitable in Sweden? Naturally there are many variables that can affect the answer; therefore a Monte Carlo methodology is used to convert the uncertainties into risks, where the results can be presented as probabilities rather than a vast collection of sensitivity analyses. Several policy scenarios are tested, where the relative impact of each current program on profitability can be seen.

    Building inspection in multi-dwelling housing and the perception of building quality2019In: Australasian Journal of Construction Economics and Building, ISSN 1835-6354, E-ISSN 1837-9133, Vol. 19, no 2, p. 144-159Article in journal (Refereed)
    Abstract [en]

    Principal-agency problems due to hidden incentives might be amplified, for example, under circumstances when unjustified trust in an inspector is associated with higher perception of building quality. This paper sets out to determine whether a significant difference exists in the owner's perception of the building quality based on the perception of the inspector and the inspection process within multi-dwelling housing. A principal-agent theoretical perspective and the question of trust is applied on data from a survey sent to 1563 housing cooperatives in Sweden and analysed using a one-sided ANOVA as well as Kruslcal-Wallis and post-hoc Dunn's test. The major finding is that differences in perception associated with the company size of the developer, the timing of the inspection as well as the complexity of the process for the owners affects reported defect. The main implication is that efforts to address shortcomings related to the gap between the developer and the owner, in the context of building quality and perceived severity of defects, need to be customised to different owner groups. A better understanding of the inspection process by the owner improves active participation, which leads to efficient quality improvement. Society benefits from improved comprehension and utilisation of the results.
