Consideration of an Agreement with Garney Companies, Inc. for pre-construction phase services for the Cedar Creek WWTP Expansion Phase 2, PN 1-C-013-25, and the Cedar Creek WWTP Solids Handling Rehabilitation Projects, PN 1-C-025-25.

________________________________________________________________________________
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 October 18, 2024, the City advertised a Request for Qualifications (RFQ) to provide Construction Manager at Risk Services for the CCWWTP Expansion Phase 2 and the CCWWTP Solids Handling Rehabilitation projects. Three (3) firms responded to the RFQ. After reviewing all proposals, the selection committee short-listed all three (3) firms for interviews. Following the interview process, the selection committee chose the team of Garney Companies, Inc. as the most qualified construction manager.
The $480,000 Agreement provides pre-construction phase services required for development of the Guaranteed Max Price (GMP). Services include providing input on design, constructability, alternative construction methods, suggestions on value engineering opportunities, participation in design workshops and charting sessions. This project is expected to be split into multiple GMP packages to facilitate expedited construction scheduling and allow for early procurement of items with long lead times. It is anticipated that the first GMP will be presented to Council for consideration in late Summer 2025.
It is anticipated that construction on this project will begin in Fall 2025 with completion anticipated in Spring 2028.
