About this opportunity
The City of St. Petersburg is seeking qualified contractors for the Northwest Water Reclamation Facility (NWWRF) Clarifier #4 Rehabilitation project located in Pinellas County, Florida. The procurement involves comprehensive rehabilitation of a 135-foot diameter secondary clarifier, including complete removal and replacement of the existing clarifier mechanism, replacement of submerged and non-submerged components, and extensive surface preparation and recoating of interior vertical masonry walls and metal supports. Key project objectives include ensuring continued performance and reliability of the plant's secondary treatment process, reducing mechanical failure risks, and extending the structural life of the facility. The project requires contractors with a minimum of five years of experience in municipal or industrial wastewater mechanical rehabilitation, successful completion of five similar projects, and a State of Florida General Contractor License. The solicitation (IFB-25-257) was released on August 15, 2025, with a pre-proposal meeting held on August 21, 2025, and bid responses due by October 2, 2025, at 3:00 pm. The total project duration is anticipated to be 240 calendar days from the Notice to Proceed, with an 11-month warranty period, and will involve careful coordination to minimize disruption to ongoing treatment processes.
The procurement includes a Small Business Enterprise (SBE) goal of 25%, encouraging participation from smaller local businesses. Contractors must provide comprehensive insurance coverage, including commercial general liability, automobile liability, workers' compensation, and pollution liability with specific minimum coverage amounts. The project will utilize an Ovivo center column, drive mechanism, and spiral scraper design, with a contingency allowance of $15,000 for unforeseen structural or surface repair conditions. Payment will be structured in three stages: 10% upon mobilization and submittal approval, 60% based on progress and verified work completion, and 30% upon final completion and acceptance. While a specific total project budget is not explicitly stated, the rehabilitation involves complex mechanical and coating work with specialized Tnemec epoxy coating systems designed for long-term performance in wastewater environments. The project includes rigorous quality control measures, manufacturer oversight, and detailed testing protocols to ensure long-term performance and asset protection. Vendors will be evaluated based on technical qualifications, experience with similar municipal water treatment infrastructure projects, and ability to meet stringent performance and coating specification requirements.
Opportunity text
This project involves the rehabilitation of Clarifier #4 at the City of St. Petersburg's Northwest Water Reclamation Facility (NWWRF). The work includes removal and replacement of the existing clarifier mechanism, which has reached the end of its service life, as well as replacement of both submerged and non-submerged components. The project is necessary to ensure the continued performance and reliability of the plant's secondary treatment process, and to reduce the risk of mechanical failure that could impact operational compliance.
In addition to mechanical rehabilitation, the interior vertical masonry wall surfaces and associated metal supports will be cleaned, prepared, and recoated with a high-performance protective coating system. Surface preparation will be performed in accordance with current SSPC standards, followed by installation of a Tnemec epoxy system designed for long-term performance in aggressive wastewater environments. This will improve corrosion resistance and extend the life of the structure.
The project also includes an owner-directed contingency allowance to address any unforeseen structural or surface repair conditions identified during construction. All work will be coordinated with plant operations to ensure minimal disruption to ongoing treatment processes. Manufacturer involvement, qualified application personnel, and strict quality control procedures are included to ensure that installation meets specification standards and delivers long-term asset protection.
