Developing Tools to Mitigate the Impact of Design Errors and Omissions
This project has three main objectives as follows: (1) evaluate the impact of design errors and omissions (E&O) and rework on schedule delays and project costs; (2) develop implementable DQC tools to minimize the negative impacts of design E&O and rework; and (3) develop or improve policy and procedures document to handle design E&O. There are several benefits of conducting this research. First, Wyoming Department of Transportation (WYDOT) will have quantitative and qualitative data regarding the impact of design E&O and rework on transportation projects' schedules and cost performance. The research team will analyze a representative sample of WYDOT projects considering different types of work, project delivery methods, size, technical complexity and design responsibility. The analysis will be done qualitatively using focus groups, surveys and expert interviews to collect qualitative data regarding the impact of design E&O on WYDOT projects. The analysis will also be extended to quantitively analyze the impact of design E&O on WYDOT projects using cost and schedule metrics. Therefore, the study will provide WYDOT with qualitative and quantitative information regarding the impact of design E&O instead of relying on data fragments. Second, the research team will develop DQC tools and guidelines based on the analysis of the impact of design E&O. These tools and guidelines will help WYDOT staff ensure the quality and constructability of the project's design based on past historical E&O. Therefore, the study will enable WYDOT to detect as many design E&O as early as possible and thus to minimize their negative impact on the project. It is worth noting that these tools and guidelines will help maintain high-quality standards for in-house design. Furthermore, these tools and guidelines will assist in checking the quality of the design prepared by external consultants. Finally, this study will produce a policy document, factsheets and practical training resources for WYDOT staff to help implement the proposed tools and guidelines to facilitate the implementation of the project deliverables.
