The City of Vermilion retained KS Associates to prepare a Master Plan for extending sanitary sewer service to the unsewered areas of the eastern part of the City. KS evaluated the acreages, zoning classifications, and topography and predicted sewage flows. Next, KS evaluated the trunk sewer capacity that would be needed to convey these flows to the Wastewater Treatment Plant. The plan was presented to the Vermilion City Council, public hearings were held, and the plan was adopted by ordinance. This analysis led to recommendations for constructing a new sewer system along US 6/East Liberty Avenue.
KS Associates prepared plans, specifications and an opinion of probable construction costs for Phase 1 of the East Liberty Avenue Sanitary Sewer. The project route was along US Route 6 / East Liberty Avenue from Ferndale Avenue east to Helen Drive, north on Helen Drive to Edgewater and east on Edgewater. The design included 2,026 lineal feet (L.F.) of 15-inch PVC sanitary sewer, 1,605 L.F. of 8-inch PVC sanitary sewer, manholes and appurtenances. The project also included a sanitary Lift Station at the northeast corner of East Liberty Avenue and Helen Drive.
The cast-in-place wet well for the pump station was 34 feet deep and had inside dimensions of 8 feet by 14 feet. The pump station was designed for four submersible pumps but initially equipped with 2 submersible pumps, allowing for future expansion.
The project was to be financed by future tap-in fees to benefitting property owners. KS prepared an analysis and recommendation regarding the proposed cost of sewer taps, which was presented to and approved by the City Council. KS prepared notices for the benefitting property owners. The City obtained funding to build the project from the Ohio Water Development Authority (OWDA). KS Associates prepared the application for the OWDA loan.
KS Associates performed customary bidding services for the Owner including distributing bid documents, issuing addenda, and attending the bid opening. The low bidder came in at $550,818, which was 13.3% below the Engineer’s Estimate.
The City requested that KS provide construction administration services and a full-time resident project representative (RPR) for the construction phase of the project. Construction started in October 1995, was briefly suspended by a property owner’s lawsuit, and was completed in January 1997. KS held monthly progress meetings with the contractor and the owner, processed pay estimates, reviewed certified payroll reports and processed change orders. When the wet well developed cracks, allowing significant amounts of stormwater to infiltrate into the system, KS performed testing to quantify the problem, then worked with the contractor to have the deficiency remediated.
