260013-Exhibit 15-Build America, Buy America Stored Specifications.pdf

This document is a modification to Section 106 of the Standard Specifications for federal aid construction projects, specifically addressing construction materials requirements under the Build America, Buy America (BABA) Act. The specification details requirements for construction materials used in federal-aid projects, mandating compliance with sections of the Infrastructure Investment and Jobs Act (IIJA). A "construction material" is defined as items permanently incorporated into the project, including non-ferrous metals, plastic and polymer-based products, glass, lumber, and drywall.

The specification requires that all construction materials and manufacturing processes occur entirely within the United States, with a "manufactured product" defined as an item undergoing one or more manufacturing processes before being used in construction. Contractors must provide Certificates of Compliance to the Engineer, confirming that construction materials meet the specified requirements. The document explicitly excludes certain materials from the definition of construction materials, such as cement, cementitious materials, bituminous materials, and aggregates. This modification ensures strict adherence to domestic production requirements for federal aid construction projects, emphasizing the use of American-made materials and manufacturing processes.
