About this file
This is a Demolition Plan for the Cow Creek project at Death Valley National Park. The plan outlines the removal and restoration of existing infrastructure and structures during construction of new wastewater and water treatment systems. Key demolition activities include: removal of the existing Cow Creek Lift Station building (with concrete pad and valve vault), abandonment of the Coyote Loop Lift Station manhole in place, demolition of the existing RO Treatment Building, removal of above-grade pressure relief valves (PRVs), extraction of the existing air monitoring trailer, removal of two trees, and demolition of the existing pool building. All removed trees and vegetation removal must be coordinated with the NPS Botanist per Specification Section 32 01 01.
The plan specifies that existing lift stations and treatment buildings must remain in service during construction until new systems are operational and service is switched over. The contractor must restore all demolition areas to natural grade and coordinate all removals with the Contracting Officer. The plan permits alternative demolition approaches subject to Contracting Officer approval. Additional requirements include reusing all existing fire hydrants, removing and abandoning water and sewer pipes encountered during installation work, and managing trench disturbance areas through removal and replacement of asphalt, gravel, and topsoil. If the Government specifies plants for replacement due to contractor damage, replanting must occur at a three-to-one ratio, with the contractor providing water and maintenance for a minimum of three weeks following planting.
