Description of Amendment

47PF0024R0042, Amendment 0003, Hilfiker Wall Repair, Land Port of Entry, Sault Sainte Marie, MI

The purpose of Amendment 0003 is to answer Requests for Information (RFI’s) and incorporate the following changes:

II.D. Technical Proposal

Changes are provided in RED text:

Evaluation Factors:

1) Sustainability

Offerors shall complete the “IRA Sustainability Factor Table” attached to this solicitation by filling out the applicable IRA Limit they commit to meet for each IRA-Eligible Material. Based upon the offeror’s selection in the “IRA Limit Commitment” column, the associated Raw Score, a Preliminary Weighted Score, and the Preliminary Total Weighted Score will be automatically calculated.

In addition, for each IRA-Eligible Material identified in the IRA Sustainability Factor Table, offerors shall submit EPDs listing that material’s GWP. Such EPDs must meet the standards reflected in GSA’s IRA Low Embodied Carbon asphalt, concrete (and cement), glass and steel requirements (see Compliance Documentation criteria listed for each IRA-Eligible Material).

Raw Score Supplement Offerors will receive a supplemental 10 points on Raw Scores for each IRA-Eligible Material where the material’s submitted EPD reflects the lowest GWP value received in the competition for that material. For instance, where two offerors propose materials meeting the Top 20% Limit for glass, and Offeror A submits a glass EPD reflecting a GWP (Global Warming Potential) value lower than that reflected in Offeror B’s glass EPD, Offeror A and B will receive raw scores of 100 and 90 for that material, respectively. During evaluations, the Government will add Raw Score Supplements, if any, to offeror’s Preliminary Weighted Scores to calculate Final Weighted Scores. In the event of a tie for lowest-GWP values for a given material, those tied offerors will all receive the Raw Score Supplement for that material.

AMENDMENT 0003

REQUESTS FOR INFORMATION

Questions (Q) and Answers (A)

1. Q. At the pre-proposal conference for the Hilfiker Wall project in Sault Ste Marie, MI I believe you mentioned something about there being a IRA supplier map for EPD compliant materials. Are you able to share a link or send me this?

A. Here is the IRA website which I believe is open to the public.

https://sites.google.com/gsa.gov/irapmo/memos-guidance-legislation/guidance/le c-outreach?authuser=0

Here is the link to the LEC crosswalk which can help locate qualified material suppliers. for the IRA program.

https://drive.google.com/drive/u/0/folders/1fGv0YPeOsYZCAA9CkmLr43Vy8Js4k

UMW

2. Q. Please clarify the engineer’s expectation for the new facing walls. Are the Plaza Walls to be formed and cast in place concrete or constructed using pneumatically applied shotcrete? The current plans refer to both formed concrete as well as shotcrete construction of the walls.

A. Formed and Cast in place concrete is the expectation for the finished facing of the walls.

3. Q. Plan sheet C301, detail 1 Wall Section, note “Remove Corrosion Product From WWM Via Abrasive Media Blast Or Approved Equivalent”. Please clarify what this comment means in preparation of the existing mesh wall face and the extents of any preparation of the existing wire basket facing. Please provide a metal prep specification to the type/extent of media blasting to an industry standard.

A.This item has been removed and is no longer required. See Addendum 1 drawings.

https://sites.google.com/gsa.gov/irapmo/memos-guidance-legislation/guidance/lec-outreach?authuser=0 https://sites.google.com/gsa.gov/irapmo/memos-guidance-legislation/guidance/lec-outreach?authuser=0 https://drive.google.com/drive/u/0/folders/1fGv0YPeOsYZCAA9CkmLr43Vy8Js4kUMW https://drive.google.com/drive/u/0/folders/1fGv0YPeOsYZCAA9CkmLr43Vy8Js4kUMW

4. Q. Plan sheet C302, detail 3 Assumed (E) Concrete Pavement Section, could you please provide the MDOT Standard Plan R-45-C. This is not available with the rest of the standard plates on MDOT’s website.

A.See Addendum 1 drawings for revisions to concrete pavement.

5. Q. Plan sheet C301, detail 4 – Bottom of Facing. Please provide details on what is to happen when there is not enough space (1.23’ min. from most protruding mesh bulge) behind the existing curb and gutter. Based on our site visit photos there are several sections of the walls with conflicts. In addition, there is a conflict with an existing catch basin on the alignment – please clarify.

A.Remove and replace curb and gutter as required to install new wall facing footing. See Addendum 1 drawings for more information and for catch basins.

6. Q. The existing Hilfiker Wall facing is irregular vertically and horizontally along its alignment. Is the new wall to “straighten out” the horizontal alignment or is the contractor to best fit the wall as it weaves in and out on the horizontal?

A.Design intent is for the wall face to follow the alignment of the existing barrier wall above the Hilfiker Wall. This will result in non-uniform thickness of concrete in the new facing. In localized areas around soil nails where WWM bulges would require thicker concrete than would otherwise be necessary, WWM may be cut to allow for nail head clearances. The contractor shall ensure localized cutting of WWM, if any, does not result in instability of Hilfiker Wall until new concrete wall facing is installed and cured.

7. Q. Can the required full-time project coordinator have other duties?

A. Yes

8. Q. Is the Safety & Health Officer required to be on site full time? Can they have other duties?

A. They should be on site full time. They can have other duties

9. Q. Is the Waste Management Coordinator a full-time on-site person with dedicated duties?

A.They can have other duties. Does not need to be a dedicated individual.

IRA MATERIAL REQUIREMENTS FOR CONCRETE

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.

*"HIGH EARLY STRENGTH" IS CONCRETE THAT, THROUGH THE USE OF ADDITIONAL CEMENT,

HIGH-EARLY-STRENGTH CEMENT, OR ADMIXTURES, HAS ACCELERATED EARLY-AGE STRENGTH

DEVELOPMENT. HIGH EARLY STRENGTH CONCRETE PRODUCED USING ADDITIONAL CEMENT SHOULD BE AVOIDED WHERE POSSIBLE, DUE TO ITS HIGHER EMBODIED CARBON. AN AFFECTED PROJECT DELIVERY TEAM MUST OBTAIN WRITTEN APPROVAL FROM GSA'S IRA PMO ON WHETHER HIGH EARLY STRENGTH CONCRETE IS NECESSARY FOR TECHNICAL REASONS. THIS 30% ALLOWANCE REFLECTS

INPUT FROM BUILDING SUSTAINABILITY EXPERTS, GENERAL CONTRACTORS, ENGINEERS, AND

READY-MIX OR CEMENT PRODUCERS.

ENERGY STAR ENERGY PERFORMANCE SCORE EXPLAINED

A. ENERGY STAR ENERGY PERFORMANCE SCORES (EPS) SHOW HOW EFFICIENTLY A

MANUFACTURING PLANT USES ENERGY ON A 100-POINT SCALE. A SCORE OF 50 REFLECTS

AVERAGE PERFORMANCE, 1 SHOWS POOR PERFORMANCE, AND 100 REFLECTS HIGHEST

PERFORMANCE.

B. CONTRACTORS OBTAIN EPS'S BY REQUESTING PRODUCERS OF CEMENT, GLASS, ASPHALT MIX, AND STEEL (FROM INTEGRATED MILLS ONLY) TO PROVIDE THE SCORE. OR, CONTRACTORS MAY

REQUEST IT FROM MATERIAL SUPPLIERS (E.G., CONCRETE PRODUCERS).
