Body
FISCAL IMPLICATIONS:
Sewer Enterprise Funds in the amount of $300,000 have been appropriated by City Council for this project. Please see Attachment 1 (Tables 1 and 2) for budget, expenditures and progress payment details.
BACKGROUND:
This project is a result of the Wastewater Master Plan completed in 2010. Upon the inspection of 2,031 sewer manholes, the Wastewater Master Plan identified the manholes in need of repair and rehabilitation due to deterioration from age and high traffic loading. Staff has developed a maintenance program and has merged all recommended repairs through 2015 into one project for economic benefits gained by the City.
The 2012-2015 Rehabilitation of Sewer Manholes Project included the rehabilitation, repair and/or replacement work on 60 manholes. One (1) manhole was removed and replaced. Two (2) manholes had manhole frames and covers replaced. Eight (8) manholes had concrete flow channels repaired. Sixteen (16) manholes were lined with a long-lasting, spray-on interior lining and thirty-three (33) manhole frames and covers were replaced on manholes located on Sepulveda Boulevard.
On May 7, 2013, City Council authorized the City Manager to award a construction contract in the amount of $171,124 to Miramontes Construction Co., Inc. for the 2012-2015 Rehabilitation of Sewer Manholes Project, and execute a professional engineering services contract with Wallace & Associates Consulting, Inc. in an amount not-to-exceed $48,824 for construction management and inspection services.
DISCUSSION:
Construction started on August 12, 2013. Because the manholes were dispersed around the City, notices were distributed to the adjacent residents as the work progressed. Sewer Manhole Rehabilitation project mobilization included construction staging, stormwater pollution prevention measures and traffic control for each work location. In accordance with the contract, the Contractor has completed the entire removal and replacement of one manhole; repaired the concrete channel and bench bases on eight manhole locations; finished the spray-on interior lining of sixteen manholes; and replaced a total of thirty-five manhole frame and covers at various locations throughout the City. The thirty-three sewer manholes located within the State Highway right-of-way (on Sepulveda Boulevard) required a permit from the California Department of Transportation (CALTRANS) and necessitated significant traffic control while the work was performed.
Change Orders
All line items under contract have been accounted for in Progress Payments No. 1 and 2. The Final Payment for this project includes two extra work items accounted for in Change Orders No. 1 and 2. Change Order No. 1 involves additional work to raise an existing manhole ring and cover to grade at Marine Park. Change Order No. 2 consist of additional concrete flatwork to remove and replace displaced and damaged curb, gutter and sidewalk; and curb ramp surrounding an existing manhole location at the southeast corner of Highland Ave and 34th Street. This manhole location was part of the original contract work; however, the extent of the pavement restoration was in addition to the contract.
CONCLUSION:
The Contractor has completed all contract work and is requesting formal acceptance of the work and final payment in the amount of $14,161.00. A five percent (5%) retention in the amount of $9,264.25 would be released upon the expiration of 35 days after recordation of the Notice of Completion with the County Recorder. All work inspected by the Public Works Department has been found to be in conformance with the plans and specifications.
