Repair Deep Well 051 for Closure - Amendment 0004 - Q&A

The Army Contracting Command - Rock Island is soliciting proposals for the repair and permanent closure of Deep Well 051, a disused 380-foot-deep water well located adjacent to the Water Treatment Plant at Rock Island Arsenal, Illinois. The work, defined under NAICS code 237110, requires sealing the unsealed portion of the well using specified fill materials including washed pea gravel, bentonite slurry, neat cement, and fill dirt, with all work performed in accordance with the Statement of Work for Project #2026-0214 and its accompanying technical attachments. The contract is structured as a firm-fixed-price arrangement with separate line items for base work and fill materials, where payment will be based on actual, verified quantities installed on-site and signed off daily by the Contracting Officer’s Representative. The total estimated value is not specified, but the pricing structure includes a base bid excluding fill and four variable fill material CLINs. Proposals must be submitted via email by June 10, 2026, at 10:00 AM Central Time to designated points of contact, with mandatory inclusion of a current, valid Illinois license for the proposed on-site supervisor or project engineer—failure to provide this disqualifies the proposal. Additional requirements include a bid bond of 20% of the bid price or $3 million, whichever is less, and performance and payment bonds equal to 100% of the contract price upon award. The solicitation mandates strict compliance with federal and state regulations, including submission of a detailed Contractor Quality Control Plan and Accident Prevention Plan, adherence to environmental protocols due to proximity to an active RCRA site, and mandatory NCIC-III background checks and temporary fencing for all site personnel. All offerors must maintain an active, updated registration in the System for Award Management (SAM), including accurate business size representation under the applicable NAICS code, and must comply with annual certifications and representations. Contract administration requires use of the Wide Area WorkFlow (WAWF) system for invoicing and receiving reports, with contractors required to submit updated electronic submittal registers with each invoice and monthly. Records must be retained for three years after final payment, and liquidated damages of $1,000 per calendar day will apply for delays beyond the 90-working-day performance period from Notice to Proceed. Evaluation is based on technical acceptability as a pass/fail gate, followed by consideration of past performance and price, with
