Collaborative Design Technologies And Methods For Sustainable Built Environment, Kalle Kahkonen, Jaakko Huusko, Taija Puolitaival

CIB Conferences

In the present design process, designers still operate relatively alone, each in their own "swimming lane". Coordination between different design trades typically takes place in BIM coordination meetings organized by consultants. The process is reactive, and the feedback loops are long and error prone. Reaching successfully multi-criteria design solutions can be very difficult. This is eminently a burning issue with sustainability which is imposing new criteria and requirements for design solutions. Collaboration is widely understood as a necessity to successfully manage the ever-increasing complexity and demands of construction. Advanced collaboration consists of frequent reliable information sharing and constant working together. …
