Constructability review is a process used during project design to infuse construction knowledge into the design process. There is industry impetus encouraging early construction involvement in project development. State transportation agencies often have to abide by legislation restricting these procurement methods leaving construability review as the only opportunity for early construction involvement. Staffing and budgetary constraints lead to state transportation agencies being very cautious in the practices and processes they implement that seemingly lie outside the main missions of project development and delivery. Without straightforward and documented savings of constructability review processes, these methods may also be eliminated. After streamlining the constructability review process for the Kentucky Transportation Cabinet, an effort was undertaken to estimate monetary benefits from such reviews. Constructability reviews were evaluated at the project level by comparing change order percentages on projects reviewed versus those not being reviewed. This approach showed a clear indication that there are monetary savings associated with constructability reviews resulting in a conservative estimate of 1.25 percent of the project budget. This estimate did not include the additional inherent savings in time, lessons learned or other aspects not readily quantifiable. The second method of evaluating constructability reviews was to quantify and qualify each constructability review comment. A model was developed to estimate the potential monetary gains from the comments indicating the presence of such gains but additional analysis is needed to improve model accuracy.
