Reference: Water Treatment Plant: Engineering Services During Construction (ESDC) Contract
To: Mayor Gregory Mills and Members of City Council
Through: Michael P. Martinez, City Manager
Prepared By: Scott Olsen, Interim Director of Utilities
Date Prepared: July 20, 2023
PURPOSE
Requesting City Council’s approval for the procurement of Engineering Services During Construction by accepting a waiver of solicitation thereby awarding a contract to Brown & Caldwell, and approving the resolution giving the City Manager, or designee, authority to sign the contract. Per City Code Section 3-8-60, “…The City Council may waive the formal solicitation procedure for contracts greater than one hundred thousand dollars ($100,000.00). However, any such waiver shall be implemented only if there is first a determination by the City Manager or the City Council, as applicable, that such waiver will be in the best interest of the City.”
BACKGROUND
The City entered into a contract with Brown and Caldwell in 2019 for a conceptual engineering design for a water treatment plant expansion at the existing facility and denitrification processes. Denitrification was needed to ensure the City could meet Colorado Department of Public Health and Environment (CDPHE) discharge restrictions placed on the brine discharge from the reverse osmosis (RO) plant. In 2021, the City amended the contract to reflect the design of a new water treatment plant and include design services at the City’s wastewater treatment plant (WWTP). The intent was for the City’s WWTP to treat the RO brine in order to meet the regulations of the CDPHE. In 2022, the contract was again amended to reflect the final design of the currently-scoped water treatment plant. This current scope of services includes the design of a 20 million gallon per day (MGD) WTP, biological denitrification processes, and water softening processes.
Construction of the new water treatment plant by Garney Construction (Garney) has been on-going for several months at the site. During the construction process, Garney will make submittals to Brown and Caldwell on means and methods of construction. Brown and Caldwell will either approve or deny the proposed means and methods. Also, during construction, Garney will need clarification or further information on the design and those will be submitted to Brown and Caldwell to respond. It is anticipated that several meetings may need to occur between the City, Brown and Caldwell, Garney, and Carollo Engineering (the City’s Owner’s Representative) throughout the project. These meetings will be to review submittals, seek clarification, et cetera. Lastly, Brown and Caldwell will provide plant start-up assistance, operations manuals, and record drawings to the City.
All of the above services are included in the proposed contract. The services can only be provided by Brown and Caldwell as the Engineer of Record on the water treatment plant design.
FINANCIAL IMPACT
Sufficient appropriation exists in the 2023 Capital Improvement budget allocated to this project. The financial impact of these ESDC services has always been anticipated and accounted for accordingly in the overall water treatment plant project budget.
STAFF RECOMMENDATION
Staff recommends that the City Council approve the Resolution authorizing the City Manager to execute the contract regarding Engineering Services During Construction between the City of Brighton and Brown and Caldwell.
