DEVA 249755 – Rehabilitate Stovepipe Wells Reverse Osmosis Treatment Building

STATEMENT OF WORK (SOW)

1. PROJECT LOCATION

The Stovepipe Wells areas within Death Valley National Park is located in Inyo County, California and is an approximately 2.5-hour drive (approximately 150 miles) west from Las Vegas, Nevada. The work site is located 0.22 south on Mosaic Canyon road coming off of Highway 190 at the west end of Stovepipe Wells Village. Generally, the speed limit on Highway 190 within Death Valley National Park is 65 MPH; however, there are numerous reduced speed zones within the Park.

2. OBJECTIVES:

The objective of this rehabilitation project is to make limited changes and improvements to the building to improve near-to-mid-term functionality of the facility.

3. PLACE OF PERFORMANCE:

The reverse osmosis treatment building located to the south southwest of the Stovepipe Wells Village in Death Valley National Park on Mosaic Canyon road.

4. PERIOD OF PERFORMANCE:

The Contracting Officer will specify the Period of Performance in the Construction Contract.

5. SUMMARY OF WORK:

This project’s scope of the Base is comprised of work elements that will provide for limited changes to the reverse osmosis treatment building (and equipment located within it) that was originally constructed in the early 1970s and to which multiple changes have since been made.

Roof decking will be installed on the underside of the existing concrete ceilings to prevent spalling concrete from falling from the ceilings. Most of the existing fluorescent lighting will be replaced with LED lighting – with existing plywood and pole shores to be removed. The building entrance will be reconfigured to increase the size of the entrance way from a single door to a double door. The air-exchange unit will be replaced, as will the HVAC air handler unit. The existing metal stairway will be replaced. Two tanks, calcite tank and backwash tank, used in the RO treatment system will be relocated and their associated plumbing will be replaced. The ground surface along the north, south, and east sides of the RO treatment plant building will be graded to allow for gravity flow of surface water away from the building and into the nearby natural drainage features.

The scope of Additive Bid Item #1 is to install a free-standing-workstation-overhead-bridge crane inside of the RO treatment plant building.
