The fast track project, intended as design while you build, is best suited in large scale projects, where the design stage can take years, before the construction stage may take place.  Whether the project is fast track or not, the risks remain the same, so what matters is the appropriate contract model for sharing the risks.  Such model  must include design and build, activities and inevitably leaves large management powers and the most of the risks on the contractor,. .  In my experience the FIDIC Silver Book (EPC) is appropriate for any such project, but I believe that a partnering contract  such as PPC2000 may work even better under these circumstances.. The role of the engineer/architect is closely related to the contractual framework in which he/she is called to operate and of course the principles of the substantive law of that contract.

I think you should take a close study at china's new 57 floor record breaking construction....why is it record  breaking? It is because they completed it in only 19 days....average of 3 floors per day. That sounds pretty much like fast tracking, isn't it?

The case you cited is an extraordinary achievement, but I consider fast- tracking  as a method of procurement that results in saving overall project time for the owner by preparing the design and building at the same time, rather than a means of breaking construction records. High raise building projects, with modular  sections,  may be well suited for fast tracking, and are probably an appropriate example in that aspect.  

Having personally managed two fast track hydro-power projects from scratch to completion, I am enthusiastic of fast tracking and I would recommend that this method be given consideration by developers and architects.. 

I think the answer to your question is dependent on your definition of fast-tracking, which then begs the question of with which type of contract will the project be delivered. I use a fundamental definition that fast-tracking is beginning construction before the design is complete. That covers a spectrum from starting construction with no design on one end to packaging the major features of work with corresponding design packages and starting construction when the first design package has been released for construction. The terminology of project delivery and procurement has become increasingly confusing and when one adds the international industry vernacular to one's own countries terms, it requires the researcher to be very specific in understanding contractual relationships before "naming" a given project delivery method. Having retired from a career in international construction before entering academia and international consulting, technical jargon terminology is my greatest challenge. So to all, I wish the best of luck.
