Caltrans Preconstruction Cost Analysis

The purpose of this research is to develop a set of models for preconstruction costs on highway pavement rehabilitation projects. It responds to a request from the California Transportation Commission (CTC) to identify norms for the review and assessment of preconstruction cost estimates on the State Highway Operation and Protection Program (SHOPP), and it also aims to assist the California Department of Transportation (Caltrans) to improve its methods of estimating and managing SHOPP costs.

Impacts/Benefits of Implementation: 

This proposal responds to the need to improve cost estimating and to the paucity of work on preconstruction cost estimating. It will help decision makers to estimate preconstruction costs for their projects, and to maximum utilization of available funds. The proposed models could also help to control expenditures by establishing baselines for preconstruction cost. Establishing a baseline assists in preventing overestimation or underestimation of costs, and aids in proper utilization of financial resources.

An immediate goal of this project is to enhance the value that taxpayers receive from their Senate Bill 1 of 2017 (SB1) funds. SB1 increased fuel taxes in California primarily to fund State Highway maintenance, the SHOPP, and local streets and roads.

This proposal should enhance the value to the taxpayers by enabling the CTC and Caltrans to use cost estimating and management tools that are founded in current research-based best practices.
