The Tennessee Department of Environment and Conservation is soliciting bids for the Roan Mountain SP RCC Greenway Construction project, a one-time purchase under solicitation number 32701-13917, with a response deadline of August 27, 2026, at 2:00 PM CDT. The work involves constructing a roller-compacted concrete (RCC) pavement along approximately 7,920 linear feet of trail, including site preparation such as clearing, grubbing, excavation, subgrade stabilization, and proof rolling to ensure uniform moisture and load-bearing capacity. A 4-inch layer of #33C compacted stone subbase is required, with gabion stone and rip-rap installed at bridges and boardwalks to ensure smooth transitions and erosion control. All materials must comply with ASTM standards for concrete, aggregates, and compaction, as well as the ACPA RCC Guide Specification and Tennessee state regulations. Energy Star-certified products are mandatory, and original manufacturer markings on used equipment must remain intact. The project will be performed at Roan Mountain State Park, with F.O.B. destination terms placing delivery and acceptance responsibility on the contractor at the site. The contract follows a Lowest Price Technically Acceptable (LPTA) evaluation methodology, meaning award will go to the technically compliant responder offering the lowest price. Contractors must hold a valid Tennessee contractor’s license, provide proof of commercial general liability insurance ($1M per occurrence/$2M aggregate), auto liability insurance ($1M), and workers’ compensation as required by law, with the State named as an additional insured. Insurance policies must include a waiver of subrogation, and deductibles exceeding $50,000 require prior approval. Contractors are prohibited from employing illegal immigrants, engaging in a boycott of Israel, or contracting with foreign adversary companies, and must certify compliance with the Tennessee Iran Divestment Act. All subcontractors are bound by the same obligations as the prime contractor, and no change to scope, schedule, or specifications is valid unless approved in writing by the TN Greenways and Trails Coordinator. Payment will be processed via ACH after submission of invoices to the requesting agency, and all records must be retained for five years post-final payment, subject to audit by the State Comptroller. Proposals must be submitted via the Edison Supplier Portal, and contractors must maintain up-to-date profile information, including valid login credentials, as passwords expire every 90 days and inactivity logs users out after
