Municipal Engineer Director of Public Works Township of West Orange 25 Lakeside Avenue West Orange, NJ 07052 Re: Proposal for Professional Engineering and Land Surveying Services for: Decommission of Korwel Pump Station for New Gravity Sewer Main West Orange, NJ Crew Proj. No.: P2672 Dear Mr. Lepore: In response to your Request for Proposal (RFP) dated October 12, 2022, Crew Engineers, Inc. (Crew) is pleased to present this Proposal to the Township of West Orange for providing Professional Engineering and Land Surveying Services for design and construction-related services for the decommissioning of the Korwel Pump Station and replacement with a gravity sewer main. The following outlines our Project Understanding, Scope of Services, and Engineering Fee and Billing Method. Project Understanding The Korwel Pump Station is located on Block 166 Lot 59.01, which is located behind 737 Northfield Avenue. The pump station has block walls and a wood frame roof with asphalt shingles. Power is supplied by overhead wires. Crew was advised that there was never a backup power generator or fuel storage tank on site. Heat is provided by electric unit heaters. There is a water utility connection for cooling the pumps and washdown. The pump station receives sanitary flows from several houses and commercial properties in the surrounding area. The pump station is in a state of general disrepair and the Township desires to decommission it and construct a new gravity sewer to convey the sanitary flows to an existing sewer on Northfield Avenue. That existing sewer was constructed after the pump station was operational and it extends to the driveway of 737 Northfield Avenue, approximately 190 ft from the pump station. In 2008, the Township determined that, based on invert elevations, this plan was feasible. A new sewer easement will be required for the proposed gravity sewer.
