Understanding Construction Change Orders Report

This report is a comprehensive examination of construction change orders, prepared by the U.S. DOT’s Project Delivery Center of Excellence. It identifies common issues that lead to change orders, which can cause project delays and cost overruns. The report categorizes these issues into three main areas: the quality of technical project development work, the influence of organizational culture, and the uncertainty introduced by financial factors. Additionally, it outlines best practices aimed at minimizing and mitigating change orders, while also documenting noteworthy project delivery practices utilized by various transportation project sponsors. The report emphasizes the importance of enhancing understanding of construction change orders to assist practitioners, particularly those with limited experience in federally funded transportation projects, in achieving improved project delivery outcomes. By addressing these challenges, the report aims to support the effective implementation of the Bipartisan Infrastructure Law and facilitate timely and budget-compliant project completions.
