PART 1: GENERAL

1-1 DESCRIPTION OF WORK

A. This contract provides services to inspect and clean underground, potable, concrete water reservoirs located on the Blue Ridge Parkway (BLRI) from the Humpback Visitor Center (Ridge District, MP 5.8, Augusta County, VA) to the Peaks of Otter Campground (Ridge District, MP 85.6, Bedford County, VA). This contract will inspect all identified water reservoirs, providing a detailed condition assessment and proposed mitigation plan for deficiencies discovered. A basic cleaning of the interior surfaces of each water reservoir will be performed, properly disposing of the chlorinated water, sludge, debris and other waste. In service cleaning shall be performed prior to tank inspection. After each tank is cleaned new stainless-steel lockable lids will be installed if the existing lid is damaged or not functioning properly.

B. The contract work includes:

1. Basic cleaning of each reservoir’s interior surfaces.
