Effect of IFC? · “Low friction information logistics” · Lars C. Christensen, Selvaag Blue Think · New decision processes: · Earlier access to information · Possible to simulate decisions and see the consequences earlier 10. 09. 2020 7
Information Exchange in the Building Process Legend: (Thanks to Lars C. Christensen, Selvaag Blue Think) Model Drawing Document centered File exchange: Data is not exchanged, drawings are (e)mailed. Model exchange: Data centrerd Model file Model server: Informationmodel centrerd Check out/check in data 10. 09. 2020 8 Data is exchanged on application specific formats and drawings are (e)mailed. Standardized model data Data is exchanged using a neutral format. Data is available in a neutral model server and is accessed from different applications.
