estimated 12 % to 20 %, equal to USD1 trillion to USD1.7 trillion annually , according to The Boston Consulting Group .
Most of these technologies require accurate , consistent data from different project stakeholders . Building Information Modelling ( BIM ) systems that allow stakeholders to produce , collect , store and share asset information can provide the data . As the successor to traditional computer-aided design ( 3D CAD ), BIM stores and provides 3D object data . It also can include shared information on scheduling ( 4D ), cost ( 5D ), sustainability ( 6D ) and operations and maintenance ( O & M ) ( 7D ).
Modern prefabrication , for example , relies on accurate information from BIM models to produce 3D objects and scheduling data that allow for accurate production and justin-time delivery of modules from factories to construction sites . Beyond supporting new technologies , BIM optimises and automates asset design , supports scenario testing and decision-making , verifies constructability , enables clash analysis , improves project and investment planning , ensures project control and stores information for preventive maintenance , among other functions .
Through these functions , BIM can reduce the design phase of a construction project by 30 % and its design cost by 8 %, according to a University of Maryland study . According to the same study , BIM can cut 10 % from a project ’ s construction phase and 3 % from the construction cost . In addition , BIM enables new services and can help determine which new assets best complement existing built environments .
Many industry players have yet to fully adopt BIM , despite its advantages . Design and engineering firms lead the way , followed by construction firms . Even though BIM could significantly transform O & M , asset operators lag behind other industry players , mainly because BIM is still inaccurately perceived as being a purely 3D design application , and because commercial BIM applications to support O & M remain scarce . O & M applications account for just 10 of 206 commercial applications listed in an industry database of open-source BIM applications .
To improve productivity , the IU industry must accelerate BIM adoption . Towards that end , governors of the World Economic Forum ’ s Future of Construction Initiative have prioritised BIM adoption as a critical step toward transforming the industry .
