About this file

This is a Standard Form 30 (SF 30) Amendment of Solicitation/Modification of Contract for solicitation W911S626RA001, issued by the U.S. Army Corps of Engineers on April 28, 2026. Amendment 0002 is not extending the receipt deadline for offers, and offerors must acknowledge receipt of this amendment prior to the original solicitation deadline using one of three specified methods: completing items 8 and 15 and returning copies, acknowledging receipt on each copy of the offer, or submitting a separate letter or electronic communication referencing the solicitation and amendment numbers. Failure to acknowledge receipt may result in rejection of the offer.

The amendment deletes the original "Attachment 03 - Past Performance Questionnaire" and replaces it entirely with a revised "Attachment 03 - Past Performance PPQ" dated April 29, 2026. The revised questionnaire removes non-applicable evaluation areas including software design and cost-reimbursement forecasting, and tailors performance questions specifically to Environmental Support Services Performance Work Statement requirements. The proposed due date for submissions remains unchanged. All other terms and conditions of the original solicitation remain in full force and effect. The contract documents table lists 13 attachments covering the Performance Work Statement, technical exhibits, proposal spreadsheets, past performance references, wage determination, antiterrorism/operations security requirements, visitor guide, and local site information, all dated between April 20 and April 29, 2026.
