1.9.4. Build America, Buy America (baba) [106] (ADDED 12-08-22)

Furnish construction materials manufactured in the United States. Manufacturing processes for the construction material must occur in the United States. Manufacturing processes are defined as the final manufacturing process and the process immediately preceding the final manufacturing process. Construction materials include articles, materials, or supplies that are or consist primarily of:

• Non-ferrous metals.

• Plastic and polymer-based products (including polyvinylchloride, composite building materials, and polymers used in fiber optic cables).

• Glass.

• Lumber, and

• Drywall.

Construction materials exclude cement and cementitious materials, aggregates including stone, sand, or gravel, or aggregate binding agents (e.g., asphalt binder) or additives (e.g., polymer modifiers and admixtures).

Treat items that consist of two or more construction materials that have been combined through a manufacturing process, and items that include at least one construction material combined with a material that is not listed through a manufacturing process, as manufactured products. Manufactured products that do not contain steel or iron are exempt until further notice.

Buy America preference applies to articles, materials, and supplies that are consumed in, incorporated into, or affixed to a project. It does not apply to tools, equipment, and supplies brought to the construction site and removed at or before the completion of the project (e.g., temporary aluminum scaffolding). Buy America preference does not apply to equipment and furnishings that are used at or within the finished infrastructure project but are not permanently affixed to the structure (e.g., movable chairs, desks, or computer equipment used at or within the project but are not integral or permanently affixed to a structure).

The Department will not accept items installed until all supporting documentation has been reviewed and is found to be in accordance with the contract requirements. Insufficient or unavailable documentation or documentation showing products to contain construction materials of foreign origin are grounds for removal and replacement at the contractor’s expense.

The Department has designated which materials are considered “construction materials” and will be required to meet the new BABA regulations by their respective 9-digit material codes in section MT 601 of the Montana Materials Manual. However, the Department recognizes there will be situations where a product or material may not fit the designation indicated in section MT 601. In these cases, submit documentation demonstrating or justifying the supplier or manufacturer’s position that their specific item has been misclassified to the Project Manager at least 10 business days in advance of installation. The Department, in conjunction with FHWA, will review the submitted documentation and make a determination as to how that specific product or material will be classified. These determinations will be final and will require the appropriate necessary documentation as defined above.

1.10. ADDITIONAL WORK

Additional work is considered to be any work outside the scope of the designated route or beginning and ending mileposts that are outlined in this contract.

1.10.1. Any additional work performed under this provision shall be the same type of work for which the contract was awarded and will only apply if the Contractor is set-up and operational.

1.10.2. The Maintenance Chief reserves the right to make, in writing, at any time during the work, such changes in quantities and such alterations in the work as are necessary to satisfactorily complete the project. Such changes in quantities and alterations shall not invalidate the Contract nor release the surety, and the Contractor agrees to perform the work as altered.

If additional work or changes in quantity significantly change the scope of work, an adjustment will be made to the contract. A significant change is defined as an increase in excess of 125% or a decrease below 75% of the original contract quantity item. Any adjustment for an increase in quantity shall apply only to that portion in excess of 125% of the original contract item quantity, or in case of a decrease below 75%, to the actual amount of work performed.
