Constructability reviews have been used by multiple departments of
transportation (DOTs) in the United States for more than a decade to enhance
project design documents by introducing construction knowledge to the design
process. Constructability reviews provide the contractors with a complete set
of bid documents that have a reduced possibility of encountering any obstacles
during project construction phase. The main objective of this research is to
provide NCDOT with guidelines to conduct formal constructability review
meetings with increased efficiency. Transportation agency personnel,
consultants, and contractors were interviewed to collect data relevant to
constructability review meetings best practices, advantages, and disadvantages.
The analysis of interviews results determined that conducting constructability
review meetings before 60% completion of the design phase is recommended. A
successful meeting should include project designer, project manager, and a
minimum of 3 general contractors. Attendees should receive advanced information
regarding the project, and meetings should be held in the construction site to
ensure proper communication. The implementation of the research outcomes will
increase the constructability review meeting outcomes, minimize cost and
schedule overruns, and enhance the overall safety of the construction project.
