Project Summary
This project will focus primarily on CM/GC method, which is Caltrans’ ADM commonly employed ADM in various completed projects. The work plan will consist of the following steps: (i) A thorough literature review of previous work pertaining to ADMs, specifically those works where CM/GC type ADM has been compared with traditional methods; (ii) understanding and collecting pertinent publicly available empirical data; (iii) developing recommendations for data needs, metrics, and a framework to evaluate CM/GC method, applicable to completed and proposed projects. For (i) the research team will use best practices for conducting literature review. For this they will leverage the extensive literature resources available with UCLA and on the internet. In addition, the work will also utilize network and connections in the industry and state agencies such as Caltrans, City of LA and County of LA, to conduct informal interviews with various key entities involved in its design and implementation to understand their perspectives. For (ii) and (iii) the investigators will access published data sources, and when necessary, reach out to authors of published studies to collect pertinent data on ADMs. This project will evaluate pertinent metrics from such data to develop a framework which can then be used to evaluate an ADM, specifically CM/GC method. Where it is found that crucial data is currently lacking for completed or proposed projects that plan to utilize the CM/GC method, the team will investigate appropriate performance indictors to serve as metrics for continual evaluation of CM/GC delivery method.
