Title

Description
Request to authorize the City Manager, or his designee, to execute amendments to Agreement 151938 with Geo-Logic Associates, Inc. and Agreement 151941 with Brown & Caldwell, Inc. to provide additional Solid Waste Support On-Call Services for the Public Works Department. Further request to authorize execution of amendments to the agreements as necessary within the Council-approved expenditure authority as provided below, and for the City Controller to disburse all funds related to this item. The additional total fee for services included in these amendments will not exceed $1,250,000.
Report
Summary
The purpose of these agreements is to provide various support services for landfills, transfer station facilities, hauling yards, and maintenance facilities. Services include engineering, environmental, groundwater monitoring, survey, and other related services as required.
The amendments are necessary because the funding is being utilized faster than anticipated due to additional and unanticipated engineering, environmental and groundwater monitoring services needed. These amendments will provide additional funds to the agreements.
Contract Term
The term of the agreements remains unchanged from the issuance of the original Notices to Proceed. Work scope identified and incorporated into the agreement prior to the end of the term may be agreed to by the parties, and work may extend past the termination of the agreement. No additional changes may be executed after the end of the term.
Financial Impact
- The initial agreements for Public Works Solid Waste Support On-Call Services were approved for an amount not to exceed $4 million, including all subconsultant and reimbursable costs.
- This amendment will increase Agreement 151938 by an additional $1,000,000, for a new total amount not to exceed $2,500,000, including all subconsultant and reimbursable costs.
- This amendment will increase Agreement 151941 by an additional $250,000, for a new total amount not to exceed $750,000, including all subconsultant and reimbursable costs.
Upon approval of the $1,250,000 in additional funds, the revised aggregate value of the agreements will not exceed $5,250,000. Funding for these amendments is available in the Public Works Department's Capital Improvement Program budget. The Budget and Research Department will separately review and approve funding availability prior to the execution of any on-call task order of $100,000 or more. Payments may be made up to agreement limits for all rendered agreement services, which may extend past the agreement termination.
