While bringing detail design forward earlier in the process no doubt sounds good in principle, and will be of benefit on the whole, does Morrell understand what it means in practice?

The usual productivity curve that BIM companies like Autodesk refer to, suggests implementing BIM is more expensive earlier on as more time is invested, but there is a saving later on as things are resolved sooner. What happens though, in the fractured marketplace we work in, if the project is shelved, or at some stage are taken over by another Architect (who might not even use BIM)? The investment curve presupposes none of this ever happens, yet my experience of working 16 years is this is more likely the case than not.

The RIBA stages are there for a reason, pretending they are merely an administrative complication is as naive as suggestion there is a saving in going from sketch design to construction docs (as some clients do), without the need for design development somewhere in the middle.
