Consideration of a Professional Services Agreement with Burns & McDonnell Engineering Company, Inc. for design of the Cedar Creek Wastewater Treatment Plant Expansion Phase 2, PN 1-C-013-25, and Cedar Creek Wastewater Treatment Plant Solids Handling Rehabilitation Projects, PN 1-C-025-25.
Body
________________________________________________________________________________
Summary:
These two projects will include the design and construction of an additional biological nutrient removal (BNR) train that will add an additional 3.5 million gallons of treatment capacity and an associated final clarifier to the BNR train at Cedar Creek Wastewater Treatment Plant (CCWWTP). Work will also include the rehabilitation and expansion of the solids thickening clarifiers, rehabilitation and expansion of the existing sludge holding cells, expansion of the biosolids processing building, that will include the installation of two new centrifuges and all necessary modifications and appurtenances for completion of this work. The infrastructure and equipment being rehabilitated was constructed and installed in 1985 and are past their useful life.
On September 13, 2024, the City advertised a Request for Qualifications (RFQ) to provide design services for the CCWWTP Expansion Phase 2 and the CCWWTP Solids Handling Rehabilitation projects. Five (5) firms responded to the RFQ. After reviewing all proposals, the selection committee short-listed three (3) firms for interviews. Following the interview process, the selection committee chose Burns & McDonnell Engineering Company, Inc. as the most qualified firm.
The $6,201,313 Professional Services Agreement provides engineering design for the BNR train, final clarifier, and the rehabilitation of the gravity thickeners. Scope and fee for the remainder of the solids handling rehabilitation and expansion will come later after the results of the Super Critical Water Oxidation Pilot are complete. Services will include project administration, surveying, flow analysis, FEMA permitting, development of a basis of design for the full expansion, development of construction plans for the BNR and clarifier and associated specifications, and bid services associated with the design.
Development of the Basis of Design Report is expected to start immediately after acceptance of this Agreement. Design is expected to start in Summer 2025 with completion anticipated in Spring 2028.
