The City of Garden Grove has various divisions requiring geotechnical services, such as Streets & Storms Drains, Water, and the Sanitary District.  Historically, however, the primary demand for geotechnical services has come from the capital projects section.  There is a need for geotechnical fieldwork, analysis, reports and studies, materials testing and acceptance, quality assurance testing, and independent analysis of civil engineering designs.

Currently, the City of Garden Grove does not have geotechnical staff or a laboratory, and therefore needs to engage the services of a consultant to meet the various geotechnical needs of capital project design and construction.

Staff sent out four requests for proposals to geotechnical firms for on-call geotechnical services.   Three of the consultants submitted a proposal.  Staff reviewed the qualifications, work experience and references of Associated Soils Engineering, GMU Geotechnical Serives, and Geocon West, and found they meet City requirements.

There is no financial impact to the General Fund. Each agreement will be established for a three (3) year period in the not to exceed amount of $300,000 each.  Funding for these services will come from the various funds used by Capital Projects and other divisions using geotechnical services.

It is recommended that the City Council:

• Approve professional service agreements, in the not to exceed amount of $300,000 per agreement in a three year period, with Associated Soils Engineering, GMU Geotechnical Services, and Geocon West for on-call geotechnical services; and 

• Authorize the City Manager to execute the agreements on behalf of the City and to make minor modifications as necessary.
