Who is driving the change toward integration of structural steel design and delivery? I t began w ith st ructural eng ineers, detailers, and fabr icators r ealizing they could speed the steel delivery process and win bids by saving projects time and money through the sharing of 3D models and pr oducing c omplete documents up front befor e the star t of erection. Now, contractors, such as M.A. Mortenson, which saw the value demonstrated on the ning to advocate the sharing of models and promoting interoperability throughout the entire building team. Owners, having seen the benefits to be gained, are starting to demand that building teams implement interoperability and BIM. To dr ive the use of this technology throughout the building t eam, strong leadership from the owner is required. One e xample of how BIM was used successfully w as w ith G eneral M otors’ $300 million V6 eng ine plant in Flint, Mich. The use of BIM enabled the st eel mill order to be placed eight weeks earlier than typically would be possible and steel erection began eight days early, says Lawrence F. Kruth, P.E. of Douglas Steel Fabricating Corp., Lansing, Mich. Construction of the plant was c ompleted five weeks ahead of schedule with no change or ders, says Samir Emdanat of the ar chitectural/engineering fir m Ghafari Associates, Dearborn, Mich. BIM enabled the pr oject’s int egrated building t eam t o sha ve 24 w eeks off what typically would have been an 85week design and construction schedule. In benchmarking previous projects, GM estimates that 3% t o 5% of total c onstruction c osts w ere sa ved b y implementing BIM on those projects. 18 BIM
