Staff recommends the City Council award a professional engineering services contract for W.O. 25-01, Contract 3: Rosemont Water Main Replacement, to Morrison-Maierle in the amount of $125,900.

The City replaces and upgrades its water utilities as part of an annual maintenance program.  This project will replace approximately 1,750 feet of existing 16-inch ductile iron water main that is in poor condition. The water mains being replaced were selected based on several criteria including age, break history, lead joint pipe, lead services, undersized water mains, and replacement prior to future projects.  This project will replace the 16-inch ductile iron water main within Turnberry Circle and Rosemont Way from Briarwood Boulevard to McMasters Road with 8-inch PVC, including all intersection lateral mains. 

The existing 16-inch ductile iron water main is located in the boulevard under and adjacent to existing utilities such as power and gas. The location and size of the water main makes repair of water main breaks difficult and dangerous.  Previous breaks on this water main have had costly private property damage. The new water main will be constructed in a standard location in the street.  When complete, this project will provide more reliable water service to residents with a looped feed.  In summary, this project is the second phase of a project completed in 2024 by City Public Works to take the 16-inch transmission main out of the residential street, place it within Briarwood Boulevard, and then replace the aging main within the residential street.

Morrison-Maierle was selected for the project using the proposal process.  Five other proposals were received from DOWL, KLJ, Performance Engineering, Sanbell, and Stahly Engineering.  The consultant selection was based on Project Team and Availability; Project Approach; and Firm Qualifications and Experience as related to the project needs.

City Council may:

• Approve awarding the Professional Engineering Services Contract to Morrison-Maierle, or;
• Not approve awarding the Professional Engineering Services contract to Morrison-Maierle. If the project is not awarded, the City's water mains in these areas will continue to be unreliable, risk property damage with breaks, and will likely experience ongoing maintenance problems and expenses.

Water main replacements were budgeted in FY25 using Water Funds in the amount of $4,800,000.  There are adequate funds to award the contract.  The remaining budget will be used for construction and materials testing.
