ABSTRACT

Constructability is considered as an effective management tool to optimize project development and meet its objectives. Implementing constructability aims at integrating construction knowledge, resources, technology, and experience into the engineering and design phases of construction projects. Constructability if applied properly can optimize the quality of design plans, cost and schedule estimates, and the utilized construction methods. Many researchers and industry practitioners have investigated constructability over the past decades.  However, no efforts have been conducted to analyze the content of constructability-related literature in regards to transportation projects. To address this knowledge gap, this paper intends to analyze previous research efforts as well as industry practitioners’ efforts regarding constructability implementation across transportation projects. The authors collected and analyzed the content of 191 documents related to constructability implementation in transportation projects in the last 30 years.  These documents include both journal articles and technical reports.  The typical journals were Journal of Construction Engineering and Management, Journal of the transportation Research Board, Automation in Construction, Journal of Performance of Constructed Facilities, Journal of Management in Engineering, Engineering, Construction and Architectural Management Journal, and Journal of Computing in Civil Engineering.  The technical reports were mainly from the Federal Highway Administration (FHWA), Construction Industry Institute (CII), and various state Departments of Transportation (DOTs) across the U.S.  The content analysis results provide a comprehensive set of trends in constructability, benefits and barriers, and recommendations to enhance constructability implementation.  This study contributes to both construction body of knowledge and practices by synthesizing essential issues in implementation of constructability in transportation projects.
