Proposed Motion: |
Move City Council award Professional Services Agreement No. WA2008.451, with Wilson Engineers, LLC, for the Loop 101 and 202 Freeway Waterline Rehabilitation Construction Management Services, in an amount not to exceed $296,750. |
Background/Discussion: |
In February 2018, the City experienced a large water main break northeast of the intersection of Price Road and the Loop 202 Santan Freeway Interchange. Staff responded quickly by shutting down the 36-inch diameter water transmission main. In the following months, the City hired a consultant and contractor to evaluate the cause and condition of damaged pipeline and perform necessary repairs. A condition assessment of the pipeline revealed that it was in poor condition and recommended that rehabilitation or replacement of the pipe should be considered. On July 15, 2021, City Council awarded Construction Manager at Risk Contract No. WA2008.401, Guaranteed Maximum Price (GMP-1), to Achen-Gardner Construction, LLC, for the Loop 101 and 202 Freeway Waterline Rehabilitation, that included the procurement of water pipe materials. The GMP-2 agreement is the next phase of the project and will include the replacement of an existing 30-inch potable waterline that crosses the Loop 202 Santan Freeway and the existing 36-inch potable waterline that crosses the Price Road (Loop 101) Freeway. The project scope of work consists of pre-construction assistance, weekly meetings, drawing submittals, inspection services, utility coordination, and project close-out. The contract completion time is 240 calendar days following Notice to Proceed. A related Construction Manager at Risk Contract with Achen-Gardner Construction, LLC, and a related Professional Services Agreement with Wilson Engineers, LLC, for the project's construction and post-design services, respectively, are also scheduled for this City Council meeting. |
Evaluation: |
The selection process was conducted in accordance with City policy and procedure and State law. Staff recommends approval of this agreement with Wilson Engineers, LLC, based on qualifications, relevant firm experience, team experience, project understanding, and project approach. |
Financial Implications: |
Through discussions with the Arizona State Legislature, with support from the Governor’s Office and various state agencies, the City was able to secure an $8,000,000 grant funding commitment from the State as part of the recently passed State budget to support this work. Staff remain in contact with State officials to develop an Intergovernmental Agreement to reimburse the City for this project. This agreement will be presented to council for consideration at a future council meeting. |
