Coordination (or Integration) Improvement was mentioned 14 times. 12 of the projects had more positive than negative mentions on Coordination due to the implementation of BIM. These positive effects were typically due to the use of clash detection only possible by the use of BIM or due to eliminated coordination sessions thanks to the automatic coordination and improved workflow that the BIM Model allowed. Some of the positive effects on coordination might come from the application if integrated design strategies used in the case studies, such as Integrated Project Delivery [IPD]. According to some of the case studies (Palomar Medical Center –McGraw-Hill, 2010b) “BIM facilitated the integrated design approach“, so the benefits of the Integrated Design approach can ultimately be seen as a consequence of BIM implementation.
There were some challenges and negative effects due to the use of BIM. They were mentioned 7 times, although only on 3 of the projects there were more negative than positive effects of BIM on coordination. Sometimes the “lack of understanding of interoperability limitations and abilities” (Expeditionary Hospital – Manning and Messner, 2008) posed problems. When the project was too big, software issues caused by the program not being able to handle so much information forced the creations of multiple models “to be able to work on the project” (US Food and Drug Administration Headquarters – McGraw-Hill, 2010b). The last point is a software issue, but because of the problems of coordination that it cause was considered as a negative effect on this KPI.
