To request Sanitary District Board approval of Amendment No. 1 to an agreement with Gannett Fleming, Inc. to provide professional engineering services including civil engineering design and construction management/inspection for the Sewer System Rehabilitation Plan Phase 1, Sewer Main Lining and Spot Repair Project Nos. 3 & 4. |
| | | | | | | | BACKGROUND
The Sewer System Rehabilitation Plan (SSRP) Phase 1 study was completed in July 2017. The study identified a list of replacement and lining projects with spot repairs. The Sewer System Rehabilitation Plan Phase 1, Sewer Main Lining Project Nos. 3 & 4 are two of the proposed projects. These projects are in a residential area bounded by Dale Street, Brookhurst Street, Trask Avenue, and Lampson Avenue. The overall length of both projects is approximately 22,813 linear feet. The work includes, but is not limited to, lining of 8-inch and 10-inch VCP pipe, spot repairs, moving and replacing sections of existing sewer mains, restoring existing sewer laterals after repair/lining, root removal, and repair of intruding laterals and manhole channels. |
| | | | | | | | DISCUSSION
The Sanitary District’s Operation and Maintenance Program identified four sewer main reaches and 30 sewer laterals that needed emergency sewer repairs. The District has requested that the consultant perform additional service to provide feasibility evaluation, construction management, and inspection services for the emergency sewer repair work.
Based on the amended scope of work, the total compensation amount of the agreement is increased from $301,049 to $386,602, which reflects an increase in compensation of $85,050 for Amendment No. 1 to cover the additional services to be provided by the consultant. |

There is no impact to the General Fund. This cost and will be financed with Sewer Funds in the amount of $85,553. |
