HomeMy WebLinkAbout09-15-2015 Item 11 - Sewerline Replacement - Marsh/Higuera/California Page intentionally left blank. Meeting Date: 9/15/2015 FROM: Daryl R. Grigsby, Director of Public Works Prepared By: Dan Van Beveren, Senior Civil Engineer SUBJECT: SEWERLINE REPLACEMENT – MARSH/HIGUERA/CALIFORNIA SPECIFICATION NO. 91186, PROJECT AWARD RECOMMENDATION 1. Award a contract to D-KAL Engineering, Inc. in the amount of $903,097 for the construction of the Sewerline Replacement – Marsh/Higuera/California project, Specification No. 91186. 2. Approve the transfer of $39,397 from the Sewer Fund’s Completed Projects Account into the project’s Construction Account. DISCUSSION The Sewerline Replacement Marsh/Higuera/California project consists of the replacement of sewerlines located on portions of California Boulevard, Higuera Street, Marsh Street, and Grove Street (see Attachment A). The scope of the project also includes the redirecting of sewer flow away from two existing railroad crossings, thus, eliminating these crossing from the City’s wastewater collection system. Background In July 2015, staff completed the design for the Sewerline Replacement Marsh/Higuera/California project. On July 21, 2015, the City Council authorized inviting bids for the project. Bids were opened on August 25, 2015, and D-KAL Engineering was the lowest bidder with a proposal of $903,097. D-KAL Engineering’s bid was higher than the Engineer’s Estimate of $870,000 (See Bid Summary, Attachment B). Since the bid was higher than the Engineer’s Estimate, Council approval of the award of the construction contract is needed. There are no special award circumstances. Coordination with Other Construction Activity In June 2015, construction began on the California Boulevard and Johnson Avenue 16 -inch Waterline Replacement project, with a scheduled completion of December 2015. Both the waterline replacement project and the sewerline replacement projects include construction on California Boulevard between Monterey and Marsh Street. The strategy of bidding the sewerline replacement project prior to the completion of the waterline project was intended to provide flexibility in coordinating work on these two blocks of California Boulevard. 11 Packet Pg. 144 D-KAL Engineering is the contractor for the waterline replacement project, and is also the lowest bidder on this sewerline replacement project. D-KAL Engineering’s construction schedule for the waterline project identifies construction work to be performed on these two blocks of California Boulevard in early October. By awarding this sewerline replacement project’s construction contract at this time will allow the contractor to perform the sewerline replacement and the waterline replacement work on these two blocks of California simultaneously. Therefore, the overall duration of work on these two blocks will be less than if the sewerline construction work started after the completion of the waterline project. The timing associated with awarding the contract now is intended to minimize the public inconvenience associated with construction. FISCAL IMPACT The current project construction budget of $960,000, funded by the Wastewater Collection System Improvements Master Account, is included in the recently-approved 2015-16 Capital Improvement Plan. With a project bid amount of $903,097, a revised construction budget of $999,397 is needed. The recommended action will transfer $39,397 from the Sewer Fund Completed Projects account, as shown in the following table: Funding by Source Construction Contract:$903,097 Current Project Construction Budget $960,000 Contingencies:$90,300 * Transfer from Completed Projects Account $39,397 Total for Construction $993,397 Total $999,397 Materials Testing $5,000 Printing and other misc. costs:$1,000 Total for Other Costs $6,000 Total Construction Budget $999,397 Sewerline Replacement Marsh/Higuera/California - Construction Funding * Current Amount Available in Sewer Fund Completed Projects Account is $102,735. ALTERNATIVES Reject all bids and direct staff to re-advertise the project. The alternative to awarding the contract would be to reject all bids and to re-advertise. There are no indications that the construction costs would be any lower. This option is not recommended.

Grigsby, Director of Public Works Prepared By: Dan Van Beveren, Senior Civil Engineer SUBJECT: MARSH-HIGUERA-CALIFORNIA SEWERLINE REPLACEMENT, SPECIFICATION NO. 91186 RECOMMENDATIONS 1. Approve plans and specifications for the Marsh-Higuera-California Sewerline Replacement Project, Specification No. 91186. 2. Authorize staff to advertise for bids, and authorize the City Manager to award the contract if the lowest responsible bid is within the Engineer’s Estimate of $870,000. DISCUSSION Background Replacement of wastewater collection pipes is part of an ongoing program to replace aging, deteriorating, or otherwise troublesome sewer infrastructure. This program has several objectives, including, provide uninterrupted sewage flow, eliminate potential health hazards and/or effluent leakage, reduce the need for emergency repairs, and reduce maintenance requirements. Consistent with these program objectives, this project includes the replacement of sewer pipelines in the vicinity of California Boulevard and Higuera Street and the removal of two sewerlines beneath the railroad tracks. Project This project is located on portions of California Boulevard, Higuera Street, Marsh Street, and Grove Street (see Attachment 1). Included within the project area are two locations where the existing sewerlines cross under the railroad tracks. In recent years, there has been an ongoing effort to eliminate existing railroad crossings from the sewer system wherever possible due to potential problems which could arise in the event of a pipeline failure at these crossings. In September 2013, a study by Filippin Engineering examined the feasibility of eliminating the existing sewerline railroad crossings at Higuera Street and at Marsh Street. The study concluded that it would be feasible to eliminate these crossings by directing the sewer flow away from the railroad tracks and into a new sewer collection line on California Boulevard. Coordination with Other Construction Activity In June 2015, construction began on the California Boulevard and Johnson Avenue 16-inch Waterline Replacement project with a scheduled completion of December 2015. Both the waterline replacement project and the sewerline replacement projects include construction on California Boulevard between Monterey Street and Marsh Street. The strategy of bidding this sewer replacement project prior to the completion of the waterline project will provide flexibility in coordinating construction work on these two blocks of California Boulevard.

These measures are proposed in an effort to minimize the public inconvenience. ENVIRONMENTAL REVIEW The Community Development Department has issued a Notice of Exemption pursuant to Section 15302 (Replacement or Reconstruction) of the California Environmental Quality Act Guidelines. FISCAL IMPACT The project is included in the 2015-17 Financial Plan, Appendix B, which budgets $960,000 for the construction of this project in 2015-16. The Wastewater Collections System Construction Master Account currently has a balance of $1,732,348, and an additional $1,456,000 has been programmed for the 2015-16 fiscal year. A budget amendment request will be completed at the time of contract award to transfer funding into this project’s account. The estimated project costs are shown below: Total Engineer’s Estimate:$870,000 Contingencies:$85,000 Materials Testing:$4,000 Printing & Misc.
