From:

Subject:
Agreement No. PW1-925-4350, with Mechanical Solutions, Inc., for Vibration Diagnostic Services
Proposed Motion:
Move City Council approve Agreement No. PW1-925-4350, with Mechanical Solutions, Inc., for vibration diagnostic services, in an amount not to exceed $120,000.
Background/Discussion:
The City provides wastewater services to over 260,000 residents. Wastewater is delivered to two reclamation facilities where it is treated to produce A+ quality effluent for delivery to the City’s reclaimed water system. The Ocotillo Water Reclamation Facility (OWRF), located at 3333 S. Old Price Road, was originally built in 1985. The Airport Water Reclamation Facility (AWRF), located at 905 E. Queen Creek Road, was originally built in 1998. This agreement will procure the services of Mechanical Solutions, Inc. (MSI), to determine the cause of the high vibration exhibited by permeate pumps located at OWRF and reclaim pumps located at AWRF. MSI has provided this same type of analysis for raw water pumps located at the Pecos Surface Water Treatment Plant and successfully designed a solution to mitigate the vibration issues exhibited by the pumps.
The project scope of work consists of onsite testing at OWRF and AWRF, data analysis, and a preliminary report. Completion time is 120 calendar days following Notice to Proceed.
Evaluation:
The City has used MSI for other troubleshooting needs, and MSI has provided successful results. Their leadership team and staff are highly qualified in their fields of knowledge and have proven capabilities as demonstrated on a previous project. Staff recommends the direct selection of Mechanical Solutions, Inc., due to their experience and familiarity with City of Chandler operations.
