Automatiserad kvalitetssäkring av BIM-data från databas : Automated quality assurance of BIM-data from databases (Swedish)
Abstract [sv]

Järnvägsbranschen står i dagsläget inför stora utmaningar med planerade infrastrukturprojekt och underhåll av befintlig järnväg. Med ökade förväntningar på  utbyggnaden av den framtida järnvägen, medför det en ökad risk för belastning på det nuvarande nätet. Baksidan av utbyggnaden kan bli fler inställda resor och  förseningar. Genom att dra nytta av tekniska innovationer såsom digitalisering och  automatisering kan det befintliga system och arbetsprocesser utvecklas för en  effektivare hantering.  Trafikverket ställer krav på Byggnadsinformationsmodeller (BIM) i upphandlingar. Projektering för signalanläggningar sker hos Sweco med CAD-programmet  Promis.e. Från programmet kan Baninformationslistor (BIS-listor) innehållande  information om objekts attribut hämtas. Trafikverket ställer krav på att attributen ska bestå av ett visst format eller ha specifika värden. I detta examensarbete  undersöks metoder för att automatisk verifiera ifall objekt har tillåtna värden från projekteringsverktyget samt implementering av en metod. Undersökta metoder  innefattar kalkyleringsprogrammet Excel, frågespråket Structured Query Language (SQL) och processen Extract, Transform and Load (ETL).  Efter analys av metoder valdes processen ETL. Resultatet blev att ett program  skapades för att automatiskt välja vilken typ av BIS-lista som skulle granskas och för att verifiera om attributen innehöll tillåtna värden. För att undersöka om kostnaden för programmen skulle gynna företaget utöver kvalitetssäkringen utfördes en  ekonomisk analys. Enligt beräkningarna kunde valet av att automatisera  granskningen även motiveras ur ett ekonomiskt perspektiv.

Abstract [en]

With increased expectations for the expansion of the future railway, this entails an increased load on the current railway network. The result of the expansion can be an increasing number of cancellations and delays. By taking advantage of technological innovations such as digitalization and automation, the existing system and work  processes can be developed for more efficient management.   The Swedish Transport Administration sets requirements for Building Information Modeling (BIM) in procurements. The planning of signal installations within the railway takes place in Sweco using the CAD program Promis.e. From the program, lists containing the information of the objects (BIS-lists) can be retrieved. The  Swedish Transport Administration requires that the attributes must consist of a  certain format or have specific values. In this thesis project, methods for automatic quality assurance of infrastructure information and the implementation of the method for rail projects were examined. The investigated methods include the  calculation program Excel, the query programming language SQL and the process of ETL.  After analyzing the methods, the ETL process was chosen. The result was that a  program was created to automatically select the type of BIS list that would be  reviewed and to verify that the examined attributes contained allowed values. In  order to investigate whether the cost of the programs would benefit the company in addition to the quality assurance, an economic analysis was carried out. According to the calculations, the choice of method could also be justified from an economic  perspective.
