The contractor requests that a provision be added to the contract that allows the SEPTA to compensate the contractor for costs that are materially increased by the implementation of tariffs on, or in connection with the work. While the project is strictly Buy America the imposition of tariffs potentially affects the pricing of subcomponents to American made products. These tariffs can adversely and unfairly affect the cost and availability of American made products after pricing proposals have been submitted and contracts signed.

Tariff section XXXVI. TARIFFS has been added to the contract: If Contractor’s costs in the performance of its duties under this Agreement are materially increased by the implementation of material tariffs on, or in connection with the Work performed under Agreement, pricing and fees may be escalated accordingly, after consultation and agreement with SEPTA, to compensate Contractor for such increased costs. As such, the parties agree to meet and negotiate in good faith to determine any appropriate and reasonable adjustments to pricing to compensate Contractor for such costs. Prior to any such meeting, Contractor shall provide all relevant information, invoices and documentation to support its claim of increased tariffs, including but not limited to, the actual amount and date of tariff imposed and the percentage of such tariff directly related to the Work, country of origin of the product or goods and any other documentation supporting or related to the claim of additional costs resulting from tariffs.

FR Vest will be required for PPE

I am currently reviewing the project specifications for Section 06610 – Glass Fiber and Resin Fabrications.

However, I am unable to locate the clear detail drawings for the fiberglass grating in the documents provided. Could you please provide the complete detail drawings for these items, or direct us to the relevant drawing sheets? These details are required for us to accurately review the scope and prepare our quotation.

The existing fiberglass panel system at Loudon TPSS could not be removed or fully disassembled during the field investigation without causing damage to the installation. As such, the condition of the panels, attachment system, gaskets, sealants, and supporting components could not be verified. The Contractor shall be responsible for evaluating the existing panel system during final design and prior to construction to determine its suitability for continued service. If the existing panels are found to be in acceptable condition, they may remain in place, with replacement of gaskets, sealants, and associated hardware as necessary to restore and maintain a weather-tight and watertight building envelope. If the Contractor determines that replacement of some or all of the panels is required, the replacement system shall comply with the requirements of Specification Section 06610 and shall match the existing installation's functional, durability, fire-resistance, weather-resistance, and aesthetic characteristics. No replacement panel details are currently shown because reuse of the existing fiberglass panels may be feasible pending the Contractor's evaluation and verification of existing conditions
