Ysleta Land Port of Entry Pavement Replacement Repairs Project, Request for Information

1) Can a company use a final CPARs evaluation instead of the past performance questionnaire?

Answer: Yes, for Factor 1 (Company), No, for Factor 2 (Key Individuals)

2) When is the proposal due?

Answer: May 16, 2024, at 12:00 P.M. Central Time

3) When is the last date a contractor can submit a question to be answered in an Amendment?

Answer: May 1, 2024, at 12:00 P.M. Central Time.

4) Which form do we fill out for Factor 4?

Answer: Fill out page 4 and 5 of the Request for Proposal (RFP) and fill out the Excel spreadsheet

(attachment 4) titled Excel spreadsheet titled Factor 4 LEC Material IRA Sustainability Factor

Table). Both the PDF and Excel spreadsheet are required with the proposal.

5) Is GSA aware of any suppliers who have an EPD that meets the GSA minimum requirements per Factor 4 in the geographical area of Ysleta?

Answer: No, GSA is unaware of any concrete suppliers in the area of Ysleta/ El Paso that currently have EPDs. A free, public Building Transparency EPD map (https://www.buildingtransparency.org/resources/maps/) is updated weekly for everyone’s information.

6) If any LEC materials are from Mexico, are we to submit all of the information required

Under FAR 52.225-11 with our proposal?

Answer: Yes. Both FAR 52.225-10 and 52.225-11 are applicable and contain necessary information you need when considering LEC materials from Mexico for this procurement. You should comply with both of these clauses and submit all necessary information with your proposal. Any information provided for the Buy American Act will not be counted in the technical 40 page limit.

7) Do I need a GACA account? (Attachment 1)

Answer: No, a GACA account is only required when GSA is unable to attached all of the attachments on SAM.Gov. GSA was successful in attaching the RFP, 14 attachments and two reference documents to SAM.gov.

8) How do we submit the proposal to GSA?

Answer: The proposal is to be sent to Jason Gerloff at Jason.gerloff@gsa.gov. This is the only vehicle for submitting a proposal.

First eight questions were answered in Amendment 1.

https://www.buildingtransparency.org/resources/maps/ https://www.buildingtransparency.org/resources/maps/ https://www.buildingtransparency.org/resources/maps/ mailto:Jason.gerloff@gsa.gov

9) As per TXDOT air entrainment in concrete for class P concrete is no longer required in the El Paso District. Will GSA accept the TXDOT Class P Concrete approved design for El Paso District without requiring air entrainment?

Answer: If air entrainment is omitted, contractor shall lower the w/c ratio to a maximum of 0.4 in order to increase the strength and ultimately the durability of the concrete.

10) Section 32 12 16 Asphalt Concrete Paving 3.3 Asphalt Surface Course calls out for Item 340 however does not specify Type or PG grade oil to be used for pavement details for HMAC underneath concrete pavement shown on plan sheet C 400. TXDOT typically specifies for this application Item 340 TXDOT Type D With PG 64-22 to serve as a bond breaker between concrete pavement and base course. Will GSA require TXDOT Item 340 Type D With PG 64-22 oil for this application?

Answer: Contractor shall use Type B with PG 64-22 or greater for the asphalt 4-inch base course.

11) Will GSA post the pre-bid attendee list?

Answer: Yes, the attendee list from the pre-proposal meeting will be included in Amendment 2.

12) Is there an interested vendors list that will be posted on the on Sam.Gov website?

Answer: As of the pre-proposal meeting (Thursday, March 21, 2024) the only interested party list is the attendees from the meeting. The sign-in sheet with their information is included in Amendment 2. All amendments are posted on SAM.Gov.

13) Are subcontractors required to be small businesses in order to collaborate with the primary contractor that has been awarded?

Answer: NO. Only the prime contractor who is awarded the contract from the Government has to be a small business. Sub-contractors can be small or large business concerns.

14) Will GSA allow the use of TXDOT Type D 1993 Recycled Concrete Crushed Base

Course (See Attached) for Flex Base as shown on Plan Sheet C400.

Answer: Yes. Refer to SECTION 32 12 16 ASPHALT CONCRETE PAVING Paragraph

2.3 BASE MATERIAL, Paragraph B. TXDOT Item 247.

15) Is there a Geotech Report available to view.

Answer: Yes, attached to Amendment 3 is the USDA Custom Soil Resource Report (45 pages).

16) Within the drawings, starting from sheet T500, there are call-outs recommending the use of concrete barricades to safeguard the worksite.

Could water barriers serve as a viable alternative for protecting the worksite?

Answer: Water barriers can be used as an alternative only on POV areas.

17) Per the solicitation, the purpose of this project is to address approximately 725,000 sf of pavement. After conducting an in-house quantity assessment, the contractor identified disparities between the quantities measured and those presented in the solicitation. Could you please clarify whether this square foot quantity pertains solely to the concrete pavement or if it also encompasses the asphaltic layer and the flex base layer?

Answer: Total square footage of pavement replacement is approximately 252,000 sf which translates to 8,500 CY of concrete considering the different thicknesses specified on the plans and 3,500 CY of asphalt.

18) Would it be acceptable for a representative end-user or Contracting Officer /

Contracting Officer Representative, who no longer holds the same role as during the referenced project, to fill out the "Past Experience and Performance of the Company" evaluation report questionnaire?

Answer: Yes, as long as it is explained what their role was during the project.

19) If you were a subcontractor and did not have direct contact with the end user representative of a similar project, can a representative of the general contractor serve as the person to fill out the "Past Experience and Performance of the Company" evaluation report questionnaire?

Answer: NO, the Past Experience and Pat Performance MUST come from the Contractor who was the Prime Contractor.

Questions 1 through 19 have all been answered in Amendments 1 through 3.

20) How will GSA handle the procurement of materials testing for this solicitation.

Will that responsibility fall to the awarded General Contractor, will that be up to the GC to decide which quality assurance subcontractor to use?

Answer: The responsibility falls under the awarded Contractor. All interested parties are to review Section 01 40 00 – Quality Assurance & Control Requirements Guidance.

21) Can a ready mix concrete mobile batch plant get an EPD without 12 months of operating data?

Answer: Yes. The latest concrete product category rule (PCR) includes Appendix Z: Deviation", allowing mobile batch plants to use estimated operating data to get an EPD. Concrete PCR version 2.3 (February 2024) notes that "Average operations for new portable plants or plants that have not been used enough to cover the 12-month period may be estimated based on operational data for similar equipment used in similar applications." Please contact concrete PCR program operator NSF International at sustainability@nsf.org or 734-476-2543 with any questions."

22) Building on question #9 from Amendment #3, asking that as per TXDOT doesn't utilize air entrainment in the El Paso District, with the answer recommending instead a water-to-cement ratio decrease to a maximum of 0.4 to increase concrete strength and durability. This would entail increasing cement content up to 38%, potentially pushing the LEC (Low Embodied Carbon) requirements beyond acceptable limits thus affecting the EPD score.

Is this adjustment deemed acceptable by GSA?

Answer: No. Reference the attached pre-existing TxDOT compliant mix designs indicating the current calculated GWP limits for Class P concrete.

23) Due to the dynamics of environmental product declaration generation, it's possible that some producers and/or suppliers may not have completed it 100%. We want to ascertain whether it's acceptable to submit a preliminary proposal through a temporary pre-qualification process, with the final certificate to be provided in subsequent weeks?

Answer: NO

24) Does the reinforcing steel and asphalt have to meet the LEC GWP requirements?

Answer: Yes. Steel must comply with the GWP requirements. Asphalt must also comply with the GWP requirements whether being used as the finished product or as a base material. Any product that is acquired outside the United States shall comply with Buy America Act, FAR 52.225-11 and 52.225-12.
