Which element is NOT required for design-build construction QA programs?

The design-build construction QA (Quality Assurance) programs focus on ensuring that the construction process meets the required standards of quality through various established elements. Core elements such as construction quality assurance, regulatory compliance documentation, and corrective action plans are fundamental to ensure that a project complies with regulations and maintains high-quality standards.

Cost estimation strategies, while important to the overall project planning and budgeting process, are not specifically required for the QA aspect of design-build construction. QA programs are primarily concerned with the quality of the materials and workmanship rather than the financial elements. Therefore, cost estimation strategies do not directly contribute to the quality assurance process and its goals, making them the element that is not a requisite for design-build construction QA programs.
