Title
Large Diameter Sanitary Sewer Rehabilitation Grade 5 and Grade 4 Manholes - South - Engineering Services Amendment 1- WS90500273 (Ordinance S-49497)
Description
Request to authorize the City Manager, or his designee, to execute an amendment to Agreement 150125 with Brown and Caldwell, Inc., to provide Construction Administration and Inspection Services for the Large Diameter Sanitary Sewer Rehabilitation Grade 5 and Grade 4 Manholes - South project. Further request to authorize execution of amendments to the agreement, as necessary within the City Council-approved expenditure authority as provided below, and for the City Controller to disburse all funds related to this item.
Report
Summary
The purpose of this project is to rehabilitate the higher priority Grade 5 and Grade 4 sanitary sewer manholes as identified by the assessment report.
This amendment is necessary because the project was phased into four design packages versus a single package. The project deliverable was changed to a manhole rehabilitation work sheet versus a typical design sheet. This change increased the overall project duration, as well as the review periods, and this amendment will provide additional time to the agreement.
Brown and Caldwell, Inc.'s additional services include, but are not limited to: administration of the construction schedule, review of submittals, issue interpretations and clarifications, certify contractor progress payments, inspections, survey, material testing, record drawings and project documents, and field administration.
Contract Term
The term of the agreement amendment is five years from the issuance of the Notice 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
No additional funding for services is needed.
