| Reason for Recommended Action/Background |
The Board of Supervisors acceptance of the work and authorization for the Director of the Division of Integrated Waste Management to record the Notice of Completion will begin the one-year construction warranty and allow staff to make the final payment to Syblon Reid. Approval of the Extended Warranty Agreement will increase the warranty duration of the concrete from one to three years.
Background
California has a statewide goal to divert 75 percent of waste from the landfill by 2020. In February 2007, the California Department of Resources Recycling and Recovery (CalRecycle) adopted Strategic Directive (SD) 6.1, which calls for a 50 percent reduction in the amount of organics being disposed in the landfills by 2020. Organic waste makes up approximately one third of the 35 million tons of waste that is currently landfilled in California. To aid in meeting the state wide 75 percent goal, Assembly Bill 1826 was passed in September 2014 requiring businesses, including state agencies, which generate certain amounts of organic waste per week to have organic waste recycling programs on or after April 1, 2016. To meet these goals, the landfill has implemented a three-part strategy: having an organic waste transfer facility, an anaerobic composter facility, and construct an in-vessel digester (liquid digester).
The Division of Integrated Waste Management has designed an in-vessel digester (liquid digester) to further divert organic waste from being disposed of in the landfill and surface impoundments. The in-vessel digester will also generate methane for electricity from the diverted organic waste. The construction of the In-Vessel Digester – Liquid and Food Processing Area & Equalization Tank System was necessary to start diverting organic waste into the in-vessel digester and to start producing methane for electricity.
Some of the concrete core samples did not achieve the specified strength by the 28th day after pouring as specified. Nonetheless, the strength continued to increase and the issue should not impact the durability of the project; however, Syblon Reid agreed to an extended warranty of three years rather than the specified one-year warranty.
The construction project was advertised for bidding on August 19, 2019 and on September 25, 2019 three bids were received. The lowest responsive bidder was Syblon Reid. On October 15, 2019 the construction project was awarded to Syblon Reid. The construction started on November 6, 2019, and finished by December 30, 2020. The proposed date of the Notice of Completions is February 23, 2021. |
