ProjNet Bidder Inquiries and Government Replies as of 27 Mar 2026.pdf

This is a Bid Inquiry Contractor Report documenting all inquiries submitted by contractors for the NESP Lock 25 project (Review W912P9-26-RA001 Lock Foundation and Site Prep). The report contains 98 inquiries sorted by comment ID and disciplinary category, with contractor questions and corresponding government responses regarding specifications, drawings, and contract requirements.

Key project details include: a $45,000,000 small business size standard under NAICS 237990 for dredging activities; inquiry deadline of March 20, 2026 (later corrected from March 6); and bid guarantee requirements as stated in the SF1442 form. Major inquiry topics address structural specifications for combination wall piling, sheet pile installation and measurement methods, deflector panel details and diaphragm plates, environmental compliance (state permits, spawning season restrictions April 12-June 30, water quality standards), timber cribbing and riprap removal procedures, stone placement methodology, excavation phasing and sequencing, hydrostatic conditions and grouting requirements, and mattress thickness specifications. Government responses clarify that alternative piling sections are permissible if minimum elastic section modulus and moment of inertia requirements are met; provide detailed definitions for payment measurement; confirm USACE as Designer of Record for deflector panels; establish that separator wall does not require temporary bracing; and address various technical specifications through planned amendments. Significant amendments (0001, 0002, and 0003) were issued to correct discrepancies in inquiry deadlines, bid guarantees, small business size standards, and provide clarifications on technical requirements, with the final inquiry period closing March 3-4, 2026.
