Approve Increase to Contract Amount and Duration Contingencies for Contract No.
WW-675, 5th/18th/Upper Larkin Street Sewer Inspection
Summary of Proposed
Commission Action:
Approve an increase of $180,000 to the contract cost contingency, and an increase of 180 calendar days (approximately six months) to the contract duration contingency, for Contract No. WW-675, 5th/18th/Upper Larkin Street Sewer Inspection; and authorize the General Manager to approve future modifications to the contract for a total contract amount of up to $2,378,170 and a total contract duration of up to 345 consecutive calendar days. Staff seeks the increase in cost contingency to perform an additional half mile of sewer and lateral inspections. The increase in duration contingency is needed to perform the additional sewer and lateral inspections and to complete post- processing videos coding, quality control, and to allow time for the City’s review and approval process.
Background: The San Francisco Public Utilities Commission (SFPUC) Wastewater Enterprise (WWE) inspects sewers to identify areas needing rep air to avoid failures in the system. WWE Collection System Division (CSD) has identified the sewers in this project to be in need of inspection based on age, size, hydraulic capacity, and/or location. The purpose of this contract is to provide inspection s ervices of these existing sewers to supplement WWE CSD staff’s on-going inspection work. The cleaning and inspection work will assist with the ongoing inspection/data gathering necessary for SFPUC WWE’s Collection System Asset Management Program.
On March 22, 2022, by Resolution No. 22-0057, the Commission awarded Contract No. WW-675, 5th/18th/Upper Larkin Street Sewer Inspection. The original contract amount was $1,998,336, and the original contract duration was 150 consecutive calendar days.
