Integrating constructability into project development: A process approach

The National Cooperative Highway Research Program initiated a research proj ect to develop a constructability review process (CRP) for transportation f acilities. The basic objective of this research was to develop a systematic approach and methodology for constructability reviews. This paper describe s the development of a CRP that meets the National Cooperative Highway Rese arch Program's research objectives. A process approach is followed to integ rate constructability improvements into project development for transportat ion projects. A function modeling tool is used to portray the interface bet ween the CRP and the project development process. The function modeling too l captures constructability functions and information necessary to perform these functions. The research method to develop the CRP is presented. The C RP has three phases corresponding to planning, design, and construction of a transportation project. Seven constructability functions are performed in each phase. The model was tested using two transportation projects of diff erent complexity.
