Cedar Hills Adjacent Properties Deconstruction and Demolition

The Cedar Hills Adjacent Properties Deconstruction and Demolition project involves the removal of structures and site restoration on approximately 15.2 acres of privately developed land adjacent to the Cedar Hills Regional Landfill in Washington. The primary goal is to restore landfill buffer requirements by deconstructing existing structures and addressing environmental considerations, including wetlands and streams identified in a draft Critical Areas Report. The project is overseen by King County’s Department of Natural Resources and Parks, with an estimated contract value ranging from $500,000 to $1,500,000. Bidders are required to adhere to specific bidding procedures, including subcontracting and apprenticeship utilization, with the bid deadline set for October 28, 2025, and a pre-bid conference scheduled for October 15, 2025. The contract documentation includes detailed technical specifications, environmental impact assessments, permit requirements, and construction drawings. Notable updates and clarifications have been issued through addenda, which revise bid submission details, wage rates, and project scope. The project emphasizes environmental compliance, with self-mitigating impacts expected during demolition activities, and aims to ensure the site’s buffer functions are restored in accordance with regulatory standards. Overall, the project represents a comprehensive effort to deconstruct existing infrastructure, address environmental constraints, and support landfill buffer zone requirements through careful planning and adherence to environmental and safety standards.
