Total Weighted Score (sum of Weighted Scores)

* The Weighted Score for each material must be rounded to the nearest hundredth decimal (i.e., two decimal places to the right of the whole number). The Total Weighted Score (sum of Weighted Scores) must be rounded to the nearest whole number in accordance with generally accepted rounding methods (i.e., numbers 5 through 9 are rounded up to the next whole number; numbers 1 through 4 are rounded down to the next whole number).

** Required construction product assemblies (such as window assemblies) are included in IRA-Eligible Materials categories and will be bound by IRA Limit Commitments. At least 80% of the assembly’s total cost or total weight must be composed of compliant IRA-Eligible Materials.

*** Where provision of concrete that qualifies under these GSA IRA Limits is impractical, GSA’s IRA Limits for cement may be applied to the cement being used in the concrete mix.

In addition, for each IRA-Eligible Material identified in the table above, offerors shall submit compliant EPDs listing that material’s GWP.

Note: By submitting an offer, Offerors consent to GSA sharing supplier names and the GWP values associated with supplier materials with the successful offeror. Technical solutions, supplier pricing and supplier-offeror terms and conditions will not be shared.

There is no LEC Materials Evaluation Weight is specifically assigned to Concrete, but offerors may consider the weight assigned to Cement as equivalent. In the event an offeror cannot submit an environmental product declaration (EPD) for concrete that meets GSA’s global warming potential (GWP) limits, the alternative is to submit an EPD to meet the GWP limits for cement.
