Bidders must submit lump-sum pricing on a fixed-price basis including all equipment, labor, delivery, temporary storage, testing, training, and associated costs, with bids due electronically through the Bonfire e-Procurement Portal no later than May 27, 2026, at 3:00 p.m. Eastern Time. The filter system must be delivered within eighteen weeks from contract execution, with liquidated damages of $500 per day assessed for delays, and the successful bidder must provide up to eight hours of onsite training during startup and commissioning at no additional cost and dedicate a responsive account executive available by cell phone with two-business-day response times. Acceptable manufacturers include Forsta Filters Inc., Tekleen Automatic Filters LLC, and approved alternates; all equipment must be new, current production items from UL-certified facilities with a minimum two-year manufacturer's written warranty from filter system commissioning. Payment will be structured as 10 percent upon shop drawing approval, 70 percent upon delivery, and 20 percent upon successful completion of operational acceptance testing.

The City of Charlotte requires bidders to complete and submit a Minority/Woman-owned Small Business Enterprise (M/W/SBE) Utilization Form documenting their own certification status and identifying all intended MWSBE subcontractors with descriptions of work or materials and corresponding utilization percentages, demonstrating exhaustive outreach efforts to maximize diverse business participation.

Additionally, all bidders must complete a Non-Discrimination Provision certification confirming they have not engaged in or condoned discrimination and must provide a References Form listing three references from clients for whom similar services have been provided. The contract requires bidders to acknowledge compliance with the City's Commercial Non-Discrimination Policy under Charlotte City Code Section 2, Article V, and the City reserves the right to reject any bid submitted with a false certification or to terminate any resulting contract for non-compliance. No specific budget range or award value is disclosed in the procurement documents; however, the contract is structured as a definite quantity, fixed-price, one-time purchase agreement with the anticipated contract effective date in June 2026.
