Title
Environmental Management Department recommending the Board authorize the Department, upon County Counsel and Risk Management approval, to release the bid documents for the Construction Quality Assurance work as related to the cap system construction of the Meyers Landfill project scheduled for the summer of 2010.
FUNDING: There is no change in Net County Cost. Through the pending Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) litigation, the County has contributed money for site investigation obtained from the County's insurance carriers which has been beneficial in development of the site closure design, and will contribute further funds for closure of the site through money from insurance carriers and Third Party Settlements. In addition, the County has applied for grant funding with the California Integrated Waste Management Board with an anticipated award date of late November. If adequate funding is not secured from the insurance carriers this Request for Bid may be cancelled.
Body
Background: The County of El Dorado is undertaking the final closure of the 11 acre Meyers Landfill disposal site. The Meyers Landfill operated from approximately 1947 through 1971 under a series of Forest Service Special Use Permits that were issued to private parties and the County of El Dorado. Waste disposed at the site included municipal solid waste from residential and commercial sources from within the southern Lake Tahoe Basin area. The site stopped receiving waste in 1971 and in 1973 the County closed the landfill and covered the waste with an interim soil cap.
Since the closing of the site in 1973 several site investigations have been conducted. As a result of these investigations, it was determined that in the best interest of public health and safety, the site would need to be remediated. In January of 2002, the United States Forest Service (USFS) issued a Feasibility Study and Proposed Plan for remediation of the site, which was later modified and termed the Supplemental Remedial Investigation/ Feasibility Study (RI/FS). The RI/FS calls for capping the waste mass with an impermeable multi-layer cover system, installation of a passive landfill gas venting system, relocation and consolidation of a portion of the waste mass directly above a South Tahoe Public Utility District (STPUD) sewer line, and installation of a surface water collection and retention system.
Reason for Recommendation: On August 4, 2009, the Board authorized the Environmental Management Department to release and advertise a Request for Qualifications (RFQ) for Construction Closure and Construction Quality Assurance as related to the upcoming cover system construction of the Meyers Landfill (Attachment A). Subsequent to this approval, the Department immediately released the RFQ with a due date of August 18, 2009.
Eight total contractors met the RFQ criteria; six qualifying for the Construction Closure work and two qualifying for the Construction Quality Assurance.
The six prequalified contractors for the Construction Closure are as follows:
1. A.J. Diani Construction CO., Inc.
2. Envirocon, Inc.
3. Ford Construction Co., Inc.
4. Guinn Construction
5. Sukut Constructino, Inc.
6. Wood Bros., Inc.
The two prequalified contractors for the Construction Quality Assurance are as follows:
1. Geosyntec Consultants
2. Vector Engineering, Inc.
With the success of this RFQ, the Department seeks to move forward with the release of the Request for Bid (RFB) to the aforementioned contractors for the Construction Quality Assurance segment of this closure project.
Attachment B: RFB Construction Quality Assurance
Action to be taken following Board approval: Subject to Board authorization, as well as County Counsel and Risk Management approval, the Meyers Landfill CQA RFB will be released immediately with a submittal response due date of December 15, 2009. The Department will return to the Board for award and contract execution.
