About this file

This document provides pre-proposal questions and answers for Request for Proposal N6274224R1312. The Naval Facilities Engineering Command issued the RFP to solicit proposals for a construction project to build a new recreation center at Marine Corps Base Guam in Finegayan. One question asked whether gaskets could be used for joints between precast manhole sections, given they are cast without grooves. The answer confirmed that preformed butyl rubber sealants meeting ASTM C990 are an acceptable alternative for sealing the joints. Specification Section 33 30 00 will be revised in an upcoming amendment to reflect this.
