Muskegon County RRC Pump Station J Overflow Wet Well Rehabilitation

I. PURPOSE

Muskegon County Resource Recovery Center (RRC), located at 698 North Maple Island Road invites contractors to bid on the rehabilitation of the Pump Station J Overflow Wet Well. Pump Station J was reconstructed in 2022, replacing the existing 50-year-old station. The former wet well has been repurposed as an overflow structure, serving as the connection point for the bypass pump of the station. However, since its reconstruction, the RRC has struggled with ground water infiltration into the wet well causing the bypass pump to run intermittently. The selected contractor shall clean and prep the structure for coating, grout seal all active groundwater infiltration, and install a coating to the interior of the wet well.

Overflow Wet Well dimensions are 8’x15’x15’ with a 10’x4’ diameter manhole structure and a 16’x4 diameter manhole up stream of the overflow wet well. Additional dimensions can be found in the attached as-built drawings

II. SPECIFICATIONS

3.07 SAMPLING & LABORATORY TESTING

A. During the project random samples of the coating material will be taken and may be sent to an independent third-party laboratory where the samples of the material will be tested in its cured and uncured state for conformance to the Performance test results submitted by the Coating Contractor. Also during coating, cured and uncured samples of the specified coating may have Gel Permeation Chromatography and Fourier Transform Infrared Spectroscopy test completed; results will be compared to the test submitted by the Coating Contractor to ensure the coating material and mixing meet the intent of the specifications.

B. Retainage samples of all components of the coating material shall be provided from every lot or batch of material used in the project. Samples will be taken from the recirculation line or return line from the pumping system

C. Random plate samples, supplied by the Coating Contractor, will be cast in a manner in which the coating will be applied and approved by the Engineer. The plate sample will be cast with the coating material pumped through the static mixer attached to the pumping system.

D. If it is determined the samples tested do not meet the Performance or Chemical submittals provided by the Coating Contractor, additional testing will be done at the Coating Contractors expense. If it is determined that two (2) samples from the same batch do not match the submittals the structures coated with that batch or lot number will be rejected and no payment will be made.
