Hilfiker Wall Repairs Project, Sault Ste. Marie, MI

The Hilfiker mechanically stabilized earth retaining wall at the Land Port of Entry in Sault Sainte Marie, MI, has distress in the form of bulging welded wire baskets, vertical and horizontal displacement of the concrete on top of the wall, and an outward lean of the walls has been noted in the Hilfiker wall system for several years. This project will address the bulging wire baskets and outward lean of the wall as well as correct poor drainage that has contributed to the wall’s movement. The project will construct a new earth retention soil nail wall and re-slope the concrete parking area above the Hilfiker wall, fortifying the wall and protecting it from continued corrosion.

The construction contractor will be required to provide an Environmental Product Declaration (EPD) for its proposed low embodied carbon concrete (including cement) & steel (rebar) that meets the Global Warming Potential (GWP) limits.  See following link to Inflation Reduction Act Pilot Program: Interim IRA Low Embodied Carbon Materials Requirements and Interim IRA LEC Material Requirements Fact Sheet.  https://www.gsa.gov/system/files/Interim%20IRA%20LEC%20Material%20Requirements%20-%20used%20in%20Pilot%20May%202023%2005162023.pdf

The Inflation Reduction Act of 2022 (IRA)

In addition to the construction opportunity reflected herein, GSA is seeking suppliers and manufacturers that are interested in supplying low embodied carbon asphalt, concrete (and cement), glass and steel materials for the project. Suppliers and manufacturers of materials meeting GSA’s Inflation Reduction Act Low Embodied Carbon asphalt, concrete (and cement), glass and steel requirements may submit an Expression of Interest to the contact below no later than <<CO to insert date>>.

Expressions of Interest should indicate materials available and global warming potential values reflected in materials’ environmental product declarations. Submission of an expression of interest grants GSA your permission to publish your firm’s contact information and offerings for use by potential offerors on GSA construction requirements. Supplier and manufacturer contact information will be published in an informational amendment issued by GSA and, potentially, in other fora.
