Integrating Constructability Tools into Constructability Review Process

This paper describes research to develop a constructability review process (CRP) for transportation facilities. This process must incorporate tools to aid in performing constructability reviews. A comprehensive review of literature and existing constructability practices provided the basis for identifying and developing 52 analytical tools for use in a CRP. Detailed descriptions of each tool were developed. Tools were classified by whether they were used to understand/communicate constructability, were used to implement/measure constructability, or were cutting edge technology/computing based. Tools were integrated into the CRP by linking a tool(s) to each constructability function of the review process. Twenty-one constructability functions were included in the final CRP model, supported by 27 basic tools. These 27 selected tools were integrated into the CRP in a user-friendly format, using tables to communicate tool concepts, rather than by merely using text. Another 25 review tools were identified as advanced tools for future application. Road maps were used to indicate the linkage between basic and future tools and the constructability functions the tools support.
