Douglas L. Smith Middle Basin Asset Renewal Project

The Douglas L. Smith Middle Basin Asset Renewal Project, managed by Johnson County Wastewater in Kansas, involves comprehensive construction, renovation, and infrastructure upgrades across multiple wastewater treatment facilities and site areas. The scope encompasses the new construction of MB-17 Sodium Hypochlorite Storage, including pre-engineered fiberglass-reinforced buildings, storage tanks, fill stations, an access roadway, and installation of excess flow and relocated effluent chemical metering pump systems. Simultaneously, extensive work is required at existing structures: MB-2 will see replacement of grit classifiers and conveyors, demolition of a belt filter press, and structural repairs; MB-3 will undergo motor control center and process valve replacements; MB-7 will receive a new natural gas-powered standby generator with automatic transfer switch; MB-8 will be upgraded with modified primary sludge pumps and replacements for scum, settled sewage, and sidestream control valves; MB-10 will be fully demolished of its existing sodium hypochlorite infrastructure; MB-11 will relocate an effluent flow meter; and MB-13 will replace primary sludge pumps, odor control fans, building makeup air units, and electrical room air conditioning. Site-wide improvements include yard piping, electrical upgrades, paving, grading, erosion control, and general restoration. All materials must be delivered in original manufacturer packaging, protected against damage and contamination, with specific protocols for mechanical equipment, unpainted components, and structural steel. Equipment must be properly labeled with manufacturer details, electrical specifications, and safety ratings. The contract mandates strict compliance with the Standard General Conditions of the Construction Contract (EJCBC No. 1910-8, 1996 Edition), supplemented by additional contractual conditions covering indemnification, dispute resolution, survival of obligations, Kansas nondiscrimination law, and audit rights. Bidders must demonstrate capability through relevant experience, facilities, reputation, and financial strength, and fully comply with all specifications. The award will go to the lowest and best responsive and responsible bidder, with a preference applied if all factors are equal. The contract requires a lump sum bid submitted exclusively through IonWave by the deadline of July 16, 2026, with mandatory pre-bid conference attendance and site visit. Performance and statutory bonds, each equal to 100% of the contract price, are required, along with liability insurance covering the County, Engineer, and consultants as primary additional insureds. The project must be substantially completed within 870 consecutive calendar days and
