Model for Constructability Approach Selection

This paper presents a model for selecting an approach to implement constructability. Constructability can be implemented using an informal or formal approach. Based upon this research, three approaches, one informal and two formal, have been identified and labeled as follows: (1) Informal approach; (2) formal project level; and (3) comprehensive tracking. The model consists of a hierarchy of decision levels. Within these levels, there exist three steps: (1) Individual assessment of owner and project characteristics resulting in a conclusion of informal or formal; (2) combining owner and project characteristics into a single conclusion of informal or formal; and (3) if formal is concluded, a decision as to whether it is formal project‐level or comprehensive tracking. To assess owner and project characteristics, a framework of variables described by parameters has been developed. The characteristics of an owner consist of four variables: (1) Owner type; (2) objectives; (3) in‐house expertise; and (4) constr...
