Staff recommends the City Council award a professional engineering service contract for design and construction administration of W.O. 25-01, Contract 2: 2025 Sewer Main Replacement Project, to Morrison-Maierle in the amount of $697,385.

The City replaces and upgrades its sanitary sewer utilities as part of an annual maintenance program.  This project will replace approximately 12,450 feet of existing sanitary sewer. The sewer mains being replaced with this project were selected based on age, video inspection condition assessment, root intrusion history, and sewer back up history.  This project will replace sanitary sewer mains that were installed between 1907 and 1953 and are made of clay tile.  These sewer mains exhibit broken and cracked pipe and many sections need yearly root intrusion removal and maintenance.  The sewer mains to be replaced or rehabilitated are in two primary geographical areas.  The first area is near South Park where 4150 feet of 15-inch to 22-inch diameter sewer trunk main will be replaced or rehabilitated.  The second area is west of Highlands Golf Club, generally bound by 10th and 14th Streets West and O'Malley and Delphinium Drives, where 8300 feet of 8-inch and 10-inch diameter sewer mains will be replaced.  

Morrison-Maierle was selected for the project based on City staff review of three project proposals submitted by prequalified firms that have considerable experience and capacity in sewer replacement and rehabilitation design using the request for proposal process (RFP).  Two other proposals were received from Sanderson Stewart and DOWL.  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 sanitary sewer collection system in these areas will continue to be unreliable and may experience ongoing maintenance problems, back-ups, and expenses.

The project was budgeted in FY25 using Sewer Funds in the amount of $5,800,000.  There are adequate funds to award the contract.  The remaining budget will be used for construction and subsequent sewer rehabilitation projects.
