Sludge Tank Rehabilitation at HRWPCF

The Town of Manchester Water and Sewer Department is requesting proposals for rehabilitation and recoating of one sludge tank at the Hockanum River Water Pollution Control Facility, with proposals due August 26, 2026 at 11:00 a.m. Work must commence November 2, 2026 and be completed by February 28, 2027. Connecticut prevailing wage rates apply.

The scope includes pressure-washing surface preparation, visual and sounding inspection with written reports and photographs, concrete repairs using compatible materials, application of a high-performance coating system approved for wastewater and sludge immersion service, quality control testing (wet and dry film thickness and holiday detection), and site cleanup and demobilization.

Evaluation is weighted equally at 50 points each between contractor experience in rehabbing and coating wastewater tanks or similar projects and total price. A bid bond or certified cashier's check equal to 5% of the total bid price, payable to the Town of Manchester, must be submitted by August 26. The successful contractor must furnish performance and labor and materials bonds equal to 100% of the contract price within ten business days of notice of award or prior to work commencement.

Comprehensive insurance is required, including workers' compensation, commercial general liability ($1 million per occurrence / $2 million aggregate), automobile liability ($1 million combined single limit), umbrella/excess coverage ($1 million per occurrence / aggregate), and owner's and contractor's protective liability ($1 million per occurrence), with the Town named as additional insured on a primary and non-contributory basis. Insurance must be maintained for the contract duration plus three years following completion.

Questions are due August 19, 2026 at 4:00 p.m. Proposals must be submitted electronically through the Town of Manchester's OpenGov Procurement Portal. Bidders are responsible for monitoring the portal for addenda and supplemental information.
