Background :

On July 11, 2000, City Council approved entering into an agreement with Sully-Miller Contracting Co. to improve Hermosa Avenue between Pier Avenue and 16th Street. The improvements included street resurfacing and striping, replacement of various concrete wheelchair ramps, driveway approaches, cross-gutter, sidewalk, manholes and the replacement of approximately 100 feet of sewer lines and appurtenant work. Please see the attached project location map.

The contractor has completed the work to the satisfaction of the Director of Public Works/City Engineer.

 

Analysis :

During construction, additional tasks, beyond the original scope of work, were required that are related to the removal and construction of sewer lines. The following extra tasks were performed by the contractor:

  • Increased the width of the sewer pipe trench with additional shoring due to the unstableness of the soil

  • Increased amount of slurry backfill

  • Removed 8" existing sewer lines and constructed 10" tie-in modification in the concrete base to install 10" sewer lines

  • Removed interfering concrete encasement and abandoned manhole

  • Removed and relocated the California Water Service line that was in conflict with the sewer line

The cost of construction of the sewer lines and appurtenant work exceeded the original bid amount due to additional work totaling $26,700. Construction costs, which include the original bid amount (sewer-related bid items = $41,320.00) plus change orders for the additional sewer-related work, total $68,020. Staff, therefore, requests that the funds remaining in Account No. 160-8409-4201 in the amount of $39,594 be transferred to this project to help cover the cost of the additional sewer-related work. Also, Staff requests an additional appropriation of $5,000 from the Sewer Fund for the work done by California Water Service to relocate and install a new water valve for the 6" water line at 13th Court and Hermosa Avenue.
