BACKGROUND
The Gaston County Solid Waste and Recycling Division is committed to providing a safe, economical, and environmentally sensitive waste disposal facility for the citizens and businesses of Gaston County that meets or exceeds all applicable regulations. Consistent with the NC Solid Waste Management Rules (15A-NCAC-138), Gaston County is continuing to expand its current landfill site in compliance with Federal Subtitle D regulations which became effective on January 1, 1998. Periodic cell construction is necessary to provide a location to meet the disposal demands of Gaston County. The next landfill cell to be built is Unit III. The Division recently completed another construction project that was required prior to this cell construction. The construction bid for Unit III Cell Construction was publicly advertised on May 9, 2023, in the Charlotte Observer, HUBSCO, the Gaston County website and Duncan Parnell. A mandatory pre-bid was held at the site on May 23, 2023. Sealed bids were scheduled to be publicly opened on June 29, 2023. Due to an insufficient number of bids received, the bids were not opened on the originally scheduled date. The project was re-advertised publicly on July 2, 2023, and the bids were received on July 11, 2023, with the following results:
Contractor Bid Amount
Shamrock Environmental Corporation $5,880,920.00
Morgan Corporation $7,481,240.00
In addition to construction, and to comply with State and Federal regulations, Gaston County is required to provide project administration and testing services for construction. HDR Engineering, Inc. of the Carolinas is the engineer of record and will be charged with the oversight of the project as it relates to design permit approval, and management of quality assurance and testing. These additional services are required by NCDEQ to obtain approval for a Permit to Operate for Unit III. The projected cost for this portion of the construction project is approximately $488,000.00
Based on bids received, this Board Action deems Shamrock Environmental Corporation as the General Contractor submitting the lowest, responsive, responsible bid. Shamrock Environmental Corporation completed all HUB/MWBE good faith efforts and submitted a bid with 7.65% HUB/MWBE participation. Approval of this Board Action formally selects Shamrock Environmental Corporation as the successful contractor, directs the County Attorney to draft all necessary contract documents and authorizes the County Manager, or her designee to execute all necessary contract documents for construction, oversight, and testing service, and transfers the required funds into the appropriate construction and professional services accounts for expenditure purposes.
