The project addresses a 1966-era well system located within a floodplain that exhibited total coliforms in recent water quality sampling and significant corrosion. Two production wells (one 6-inch and one 12-inch diameter, each 350 feet deep) and two well pumps (1,100 and 85 gallons per minute capacity) are included. All work must be performed without disrupting service to existing treatment plant buildings, with coordination in advance; work outside the standard 7:00 a.m. to 4:00 p.m., Monday–Friday schedule requires written authorization, and overtime costs ($165.00–$212.82 per hour depending on inspector type) are charged to the contractor.

Bidders must demonstrate minimum qualifications including experience constructing electrical, mechanical, structural, and instrumentation and control replacements or modifications in functioning water and wastewater treatment plants, with necessary manufacturing, field installation expertise, adequate manpower, equipment, and sufficient capital. The estimated contract value is $5.444 million over a two-year base term (potential option terms not to exceed two years require Chief Procurement Officer approval). Work is priced as a lump sum with 34 unit price items and 13 contingent unit price items; contingent allowances include $350,000 for unanticipated additional work and up to $75,000 for contingent 100-pound weight fittings. Liquidated damages are $3,950 per day. A bid guarantee of 5 percent of the total bid amount is required; performance, labor and material payment, and maintenance bonds, each equal to 100 percent of contract price, are required within 10 days of award.
