Constructability reviews have been used by the NCDOT for more than a decade to enhance the project design documents by introducing construction knowledge to the design process. The main objective of conducting constructability reviews is to ensure the project success by providing the contractors with a complete set of bid documents that have a reduced possibility of encountering any issues during the different phases of project construction. Multiple parties may be considered for their input to enhance the constructability review process of a construction project including experienced construction managers, general contractors with relevant construction experience, design engineers, and finally construction inspectors. The input of the afore-mentioned parties can reduce, or even eliminate, built-in problems and construction flaws that might affect the project activities, and/or result in project delays, or conflicts between different project parties. Thus, the successful implementation of constructability reviews at different design stages will provide a seamless flow of construction activities, which minimize project duration, and results in significant budget savings.
The main objective of this research is to provide NCDOT with a formal process to conduct successful constructability reviews meeting and attain relevant benefits to improve the overall efficiency of the construction process. The project objective is attained by providing specific outlines to follow during the constructability review meetings, determine the optimum time to conduct these meetings (65% design development), and provide the NCDOT personnel with detailed recommendations related to the conduction of follow-up meetings, and tools to measure the effectiveness of the constructability review meetings.
