About this file

This document is an Amendment (0003) to a federal solicitation for Glazing Maintenance and Repairs at the Liberty Bell Complex for Independence National Historical Park. The amendment introduces a Special Clause 1 - Economic Price Adjustment for Materials Costs, which applies to firm-fixed-price construction contracts where significant contract costs are subject to market price fluctuations.

Key details include extending the Bid Opening to Tuesday, July 22, 2025 at 3:30 PM Eastern, with a Microsoft Teams meeting (ID: 279 943 204 970 6, Passcode: d7UW94X5). The economic price adjustment clause allows for contract price adjustments based on documented increases or decreases in designated materials costs (including steel, aluminum, copper, asphalt, cement, lumber, and fuel), with adjustments only applying when unit price changes exceed ±10% from the base price. The contractor must submit written adjustment requests within 30 calendar days after the adjustment period, providing supporting documentation, and all adjustments will be reviewed and approved by the Contracting Officer.

2. Definitions

Base Price: The price per unit of material established as of the date of contract award.

Adjustment Period: A specified timeframe (e.g., quarterly) for reviewing and applying potential price adjustments.

Designated Materials: Materials subject to adjustment under this clause. These may include, but are not limited to: steel, aluminum, copper, asphalt, cement, lumber, building materials not otherwise stated and fuel.

3. Price Adjustment Conditions

• The contract price shall be adjusted (upward or downward) to reflect documented increases or decreases in the cost of designated materials, subject to the following:

o Adjustments will only apply if the change in unit price exceeds ±10% from the Base

Price.

• Price changes must be supported by published indices (e.g., commodity indexes, Consumer Price

Index, etc.) or supplier invoices.

• Adjustments apply only to quantities not yet delivered or installed.

• Contractor must keep and retain dated documentation (e.g. quotes/proposals from suppliers, distributors, etc.) that precede date of original proposal that was used in the development of their original proposal used for award of contract that can be used in support of 5) below.

• If there is a price change, and part of the delivery was received/installed prior to any proposed price change, but the remaining amount was delivered after the price change, the Adjustment

Amount = (Actual Price – Base Price) x (Quantity Required – Quantity Delivered prior to Price

Change).

• Actual Price is determined using an agreed-upon index or invoice dated within the adjustment period.

• No markup for overhead or profit shall be applied to adjustment amounts unless specifically allowed elsewhere in the contract.

5. Notification and Documentation

• The Contractor must:

o Submit a written request for adjustment within 30 calendar days after the end of the adjustment period.

o Provide sufficient documentation (e.g., original invoices, current invoices, supplier letters, index data) to support the claimed price change.

o Failure to provide timely or adequate documentation may result in denial of the adjustment and not subject to future claims under FAR 52.233-1 – Disputes.

6. Government Review and Approval
