Adoption processes for EDM, EDI and BIM technologies in the construction industry

Three strategically important uses of IT in the construction industry are the storage and management of project documents on webservers (EDM), the electronic handling of orders and invoices between companies (EDI) and the use of 3-D models including non-geometrical attributes for integrated design and construction (BIM). In a broad longitudinal survey study of IT use in the Swedish Construction Industry the extent of use of these techniques was measured in 1998, 2000 and 2007. The results showed that EDM and EDI are currently already well-established techniques whereas BIM, although it promises the biggest potential benefits to the industry, only seems to be at the beginning of adoption. In a follow-up to the quantitative studies, the factors affecting the decisions to implement EDM, EDI and BIM as well as the actual adoption processes, were studied using semi-structured interviews with practitioners. The theoretical basis for the interview studies was informed by theoretical frameworks from IT-adoption theory, where in particular the UTAUT model has provided the main basis for the analyses presented here. The results showed that the decisions to take the above technologies into use are made on three differ- ent levels: the individual level, the organizational level in the form of a company, and the organiza- tional level in the form of a project. The different patterns in adoption can to some part be explained by where the decisions are mainly taken. EDM is driven from the organisation/project level, EDI mainly from the organisation/company level, and BIM is driven by individuals pioneering the technique.

Building Information Modelling – Experts´ Views on Standardisation and Industry Deployment

The goal of the single building information model has existed for at least thirty years and various standards have been published leading up to the ten-year development of the Industry Foundation Classes. These have been initiatives from researchers, software developers and standards committees. Now large property owners are becoming aware of the benefits of moving IT tools from specific applications towards more comprehensive solutions. This study addresses the state of Building Information Models and the conditions necessary for them to become more widely used. It is a qualitative study based on information from a number of international experts and has asked a series of questions about the feasibility of BIMs, the conditions necessary for their success, and the role of standards with particular reference to the IFCs. Some key statements were distilled from the diverse answers received and indicate that BIM solutions appear too complex for many and may need to be applied in limited areas initially. Standards are generally supported but not applied rigorously and a range of these are relevant to BIM. Benefits will depend upon the building procurement methods used and there should be special roles within the project team to manage information. Case studies are starting to appear and these could be used for publicity. The IFCs are rather oversold and their complexities should be hidden within simple-to-use software. Inevitably major questions remain and property owners may be the key to answering some of these. A framework for presenting standards, backed up by case studies of successful projects, is the solution proposed to provide better information on where particular BIM standards and solutions should be applied in building projects.

The RATAS-project, in the Light of 25 Years of Development Towards Computer-Integrated Construction

In smaller countries where the key players in construction IT development tend to know each other personally and where public R&D funding is concentrated to a few channels, IT roadmaps and strategies would seem to have a better chance of influencing development than in the bigger industrial countries. In this paper Finland and the RATAS-project is presented as a historical case illustrating such impact. RATAS was initiated as a construction IT roadmap project in 1985, involving many of the key organisations and companies active in construction sector development. Several of the individuals who took an active part in the project have played an important role in later developments both in Finland and on the international scene. The central result of RATAS was the identification of what is nowadays called Building Information Modelling (BIM) technology as the central issue in getting IT into efficient use in the construction sector. BIM, which earlier was referred to as building product modelling, has been a key ingredient in many roadmaps since and the subject of international standardisation efforts such as STEP and IAI/IFCs. The RATAS project can in hindsight be seen as a forerunner with an impact which also transcended national borders.

Developing a Multidisciplinary Process View of IFC Standardization

The industry foundation classes (IFC) file format is one of the most complex and ambitious IT standardization projects currently being undertaken in any industry, focusing on the development of an open and neutral standard for exchanging building model data. Scientific literature related to the IFC standard has dominantly been technical so far; research looking at the IFC standard from an industry standardization per- spective could offer valuable new knowledge for both theory and practice. This paper proposes the use of IT standardization and IT adoption theories, supported by studies done within construction IT, to lay a theoretical foundation for further empirical analysis of the standardization process of the IFC file format.

IT-Innovationer i svenska bygg- och fastighetssektorn

Utvecklingen inom informationsteknologin (IT) har under de senaste decennierna bidragit till stora förändringar i vårt samhälle och i våra industrier. Tillgången till bland annat persondatorer, mobiltelefoner och Internet har förändrat vårt sätt att hantera information och att kommunicera. Att IT också ökat företags och industriers produktivitet och effektivitet har kunnat mätas. Detta har utgjort bakgrunden till avhandlingens frågeställning, nämligen hur IT har påverkat bygg- och fastighetssektorn. Syftet har varit att undersöka hur och i vilken utsträckning IT används inom sektorn, samt varför användningen inom sektorn sker på det sättet och i den utsträckningen. Fem datainsamlingar har utförts för att uppfylla forskningens syfte. Tre har utförts kvantitativt genom enkätundersökningar och två kvalitativt genom intervjustudier. Den kvantitativa delen inleddes med att skapa enkätverktyget, vilket sedan använts tre gånger. Datainsamlingarna har skett under perioden 1998 till 2009 och de skapar därmed, förutom ögonblicksbilder, ett longitudinellt perspektiv på utvecklingen. Tre fokusområden har identifierats som särskilt intressanta ur ett sektorsperspektiv: elektroniska affärer (EDI), elektronisk dokumenthantering (EDM) samt byggnadsinformationsmodeller (BIM). Dessa har studerats både kvantitativt och kvalitativt. Undersökningarna visar att tillgången till IT-infrastruktur inom sektorn är god, men att IT huvudsakligen används för att effektivisera befintliga arbetssätt och processer med fokus på administration. IT har också bidragit starkt till bättre kommunikationer. Dock används IT i liten omfattning för att skapa nya produkter, processer eller affärsmodeller. Entreprenörerna är de som använder IT i lägst utsträckning. Bygg- och fastighetssektorns starkt projektbaserade organisation medför svårigheter för innovationsspridning, särskilt när innovationerna kräver engagemang från flera aktörer. Tre sådana innovationer, EDM, EDI och BIM har under de senaste åren börjat spridas inom sektorn där EDM hittills nått högst användning och BIM lägst. Olika modeller för införande och implementering av IT i företagen inom sektorn har använts för att studera vilka faktorer som påverkar beslut på olika nivåer. Den praktiska nyttan eller det förväntade resultatet av varje innovation är en starkt pådrivande faktor för beslut. Initiala beslut för införande har visat sig ske på olika nivåer. För EDM sker detta i projekt, för EDI i de enskilda företagen och för BIM hos individer. EDM har tydligast fullföljt implementeringsmodellens steg, följt av EDI och därefter BIM. Fokusområdet BIM har störst potential att skapa positiva effekter samt påverkar processer och metoder i störst utsträckning. Tidiga tillämpare bland företagen har börjat tillsätta resurser för dessa förändringar, men det har ännu inte skett i samma omfattning som för de två andra områdena.
