Subject:

Construction Manager at Risk (CMAR) Pre-Construction Services Agreement No. WA2203.251, with Achen-Gardner Construction, LLC, for Water Main Replacements

Proposed Motion:

Move City Council award CMAR Pre-Construction Services Agreement No. WA2203.251, to Achen-Gardner Construction, LLC, for Water Main Replacements, in an amount not to exceed $249,641.04.

Background/Discussion:

The Water Distribution Division currently maintains over 36,000 valves and 1,242 miles of pipe in the potable water system. This project is a continuation of a Capital Improvement Program (CIP) to replace water mains that are susceptible to main breaks due to age and condition. The program evaluates water infrastructure, identifying high-priority water mains in need of replacement. Replacement of city water mains will result in improved system reliability and reduced liability from water damage as a result of main breaks.

This project includes the replacement of approximately 20,000 linear feet of water mains, ranging in size from 4-inch to 12-inch diameter, in three high-priority ranked areas in the central part of the city: Arrowhead Meadows, Tyson Manor, and Sunset Manor. On May 25, 2023, City Council approved Resolution No. 5683, authorizing the acquisition of real property rights required to complete this project. Some public water mains are being relocated from the alley to the front of the homes and will need to tie into the existing house water connection at the back of the home. New water services will be installed for each residential structure.

The project scope of work consists of meetings and workshops, developing schedules and phasing plans, long lead analysis, equipment plan, design document reviews, utility investigations, cost model, subcontractor and major supplier selections, guaranteed maximum price (GMP) proposal, and coordinating access authorizations and easements. The agreement completion time is 365 calendar days following Notice to Proceed.

Evaluation:

The selection process was followed in accordance with city policy and procedure and state law. Staff recommends agreement award to Achen-Gardner Construction, LLC, based on qualifications, relevant firm experience, team experience, project understanding, and project approach.
