About this file

Written by GovTribe AI ·

This document is a Questions and Answers (Q&A) file for a Fiber-Reinforced Polymer (FRP) Mat procurement for the Engineer Research and Development Center Geospatial Science Laboratory (ERDC GSL). The Q&A addresses three key technical specification inquiries from a potential vendor.

The first question confirms that vinyl ester resin can be substituted for the originally specified polyester resin. The second and third questions clarify weight specifications, with the government confirming that panels weighing between 145-150 pounds are acceptable, despite the original specification listing approximately 120 pounds. The document emphasizes that while weight does not have a specified tolerance, other properties with tolerances are detailed in the solicitation document.

Fiber-Reinforced Polymer (FRP) Mat for ERDC GSL

Question and Answer

Question #1 – Per the specifications (Section 3.2.1. FRP material.) They call out use of polyester resin. We generally utilize vinyl ester which is a strong resin. Would vinyl ester be an acceptable alternative?

Answer 1 – Yes, vinyl ester would be acceptable.

Question #2 – Per the specifications (Section 3.3.2. Weight.) They list the approximate weight of the panels shall be approximately 120 lbs. We believe the part to be 145 to 150#, is this acceptable.

Answer 2 – The weight of the panels does not have a tolerance. If the vendor can make a mat that meets the specifications in the solicitation, then 145 lbs to 150 lbs is acceptable.

Question #3 – Can you please advise what is the tolerance on weight (+/-) solicitation describe

120 pounds per panel.

Answer 3 – No tolerance on the weight. The properties that have a tolerance are listed in the solicitation.
