GENERAL MANAGER'S RECOMMENDATION
recommendation
RECOMMENDATION:
Approve an amendment to the Professional Services Agreement with Ninyo and Moore to provide on-call Materials Testing, Inspection, and Geotechnical Testing Services for Collection System and Treatment Plant projects, PSA2019-003, for an additional amount not to exceed $300,000, for a total contract amount of $600,000.

BACKGROUND
The Orange County Sanitation District (Sanitation District) uses outside specialty Consultants for on-call materials testing, inspection, and geotechnical testing services in support of the Capital Improvement Program, small construction projects, and maintenance projects during the planning, design, and construction of facilities both inside the plants and for the collections systems.
RELEVANT STANDARDS
* Ensure the public's money is wisely spent
PROBLEM
Currently, the Sanitation District has contracts with three firms that provide these services. One of these firms, Ninyo and Moore, is providing geotechnical inspection and testing services for the Newhope-Placentia Trunk Sewer Replacement Project, Project No. 2-72 B&C, and their current contract amount is not sufficient to adequately complete the work.
PROPOSED SOLUTION
Approve an amendment to increase the contract amount with Ninyo and Moore to provide the necessary geotechnical testing for this critical project. The additional amount is based upon a forecast to project completion. The Sanitation District awarded two other contracts to provide similar services and those firms are being utilized on other current Sanitation District projects. Using the same firm on this project brings consistency and efficiency for this difficult project.
