Consultant Services The corrosion prevention coating being installed in the potable water tanks must not only be installed by a contractor certified by the manufacturer, but also requires specialty inspection services to ensure proper surface preparation and humidity control before the coating is installed. Performing the specialty inspection will preserve the manufacturer's warranty of the product. Engineering staff called several corrosion prevention coating inspection firms and received two proposals for the needed services. Staff recommends awarding a contract to provide specialty inspection services to CSI Services, Inc. for the not-to-exceed amount of $99,953 (see Attachment 3). MurraySmith, formerly Quincy Engineers, is needed on the project to provide construction support services. These services will include reviewing shop drawings and other submittals, providing responses to requests for information during construction, and conducting the pre-sandblast and post-sandblast inspections needed to identify all required metal repairs on all three tank interiors. In addition, their subcontractors will review the installation and start-up of the temporary VFD pumping system; and monitor the cathodic protection installation and perform post installation system checks to ensure it is working correctly. MurraySmith also provided some additional design work to complete the project plans and specifications outside of the original scope of services. Staff recommends awarding a contract amendment to MurraySmith in the not- to-exceed amount of $110,345. This amount includes $101,345 for the needed construction support services, and $10,000 to pay for the additional design services already provided (see Attachment 4). Budget A total of $3.15 million is available for this project in the Capital Improvement Program; $730,000 in the Ruby Hills —Additional Water Storage Project, CIP No. 15146, and $2,420,000 in the Bi-Annual Tank Corrosion Repairs Project, CIP No. 18127 for the work on the Moller and Laurel Creek tanks, and the cathodic protection work at all three tanks. (Note: $950,000 was originally budgeted in CIP No. 15146, but City Council approved a transfer out in the amount of $220,000 to CIP No. 17135 in order to fully fund the urgent fire hydrant lateral replacement project on W. Las Positas Blvd. to ensure fire hydrants would remain in service.) The estimated total expenditure for this project is estimated at $2,426,528. This amount includes all expenditures to date, the construction contract award in the amount of $1,730,700, a contingency of 15 percent of the construction contract amount ($259,600) for any unforeseen but necessary work discovered during construction, and the needed construction support services, specialty inspection services, and additional design services. See Attachment 1 for the funding and expenditures summary. The Operations Services Department performs annual tank cleaning and inspection, repairs and improvements with funding from the Bi-Annual Tank Corrosion CIP and will be expending a portion of the remaining $723,472 on upcoming scheduled projects.
