• Abstract:
  The main objectives of this research are to quantify the impact of design errors and omissions (E&Os) in Wyoming Department of Transportation (WYDOT) highway construction projects, identify their causes, propose mitigation strategies, develop tools to minimize the adverse effects of E&Os, and create plans and procedures for effective management. This will be achieved through analyzing change order data and insights from DOT professionals by utilizing questionnaire surveys and semi-structured interviews. This report recommends an updated design review checklist for WYDOT to assist new engineers. It identifies communication issues as a major cause of design E&Os and highlights that plan and estimate errors increase project costs and change orders. To improve coordination, the report advocates for introducing real-time collaboration platforms. It also stresses the differing perspectives of design and construction staff on causes, impacts, and the use and effectiveness of design quality control tools. Finally, this research provides an updated policy and procedure document to handle design E&O.
