CACH Administration Office Asbestos Tile Floor Removal Project

NATIONAL PARK SERVICE

INTERIOR REGIONS 6 | 7 | 8

1. PROJECT OVERVIEW

2. LOCATION AND FACILITIES

a. Canyon De Chelly National Monument (CACH) Administration Office Asbestos Tile Floor

Removal Project is located within the boundaries of the Canyon De Chelly. Located in

Northeastern Arizona, about 3 miles East from the Highway 191 on Indian Route 7.

b. The Park North Boundary runs along Indian Route 64 and Southern Boundary along

Indian Route 7, Additional boundaries to the West is locate along the Eastern City

Boundary of Chinle to the East the Western Boundary City of Tsaile.

1 Short Project Description

Contractor will be responsible for removal of existing Carpet floor, asbestos tile floor, vinyl, and wood cove base.

1. There is one layer of Carpet covering the Asbestos tile floor. The top layer was installed in 1980 over the existing asbestos tile and mastic. Both layers are damaged and required removal for new carpet tiles. The original tile and mastic (Flintkote Classic XI) is damaged and presents an indoor air quality hazard. No reinstallation of tile is required.

Additionally, the work in this project will:

• Provide construction oversight and management.

• Level concrete floors at high spots

• Repair all visible concrete floor fractures, dips, chips, and any other deficiency

• Apply concrete sealer in area of work

• Complete all services in co-operation with National Park Service staff

Project Description and Technical Requirements

89 Existing Conditions

90 Background

The beautiful Canyon de Chelly lies in the heart of the Navajo Nation located near the Four Corners area in northeastern Arizona. The canyon is home to a variety of cliff dwellings and additional archeologically significant sites as well as an important cultural site for the Navajo Nation. Canyon de Chelly National

Monument was established as a National Park Service (NPS) unit in 1931 and features numerous structures important in the development of the NPS, including the subject of this scope of work – the

Visitor Center.

91 Existing Site Description

The existing visitor center at Canyon de Chelly was built in the mid 1960’s, under the NPS “Mission

66” program. This program was created after World War II to modernize, enlarge, and reinvent the

National Park System. The visitor center was designed by Cecil Doty, an architect with the NPS. Doty is well known for the quantity and quality of his design work for the NPS, beginning in the 1930’s, and contributing to the development of the “NPS Rustic Style.” In the 1950’s and 1960’s, Doty made the transition to a more modernist style, stripped of obvious associations with regional context. Doty's designs are also known for being modest and utilitarian.

The visitor center is constructed with a combination of reinforced concrete block masonry walls, wood frame walls, heavy timber construction using glue-laminated beams and rigid frames

(assembled with bolted steel connectors), and wood joists and rafters. The floors are slab on grade, and the foundations are reinforced concrete block on concrete spread footings. Finishes include resilient tile, carpeting, gypsum board, acoustic ceiling tile, wood paneling, tongue and groove ceiling boards and plywood decking. Originally, the building had large, roofed “portals” at the front and rear entrances, and a built-up roof.

The original mechanical and electrical systems were conventional for their time. The original mechanical system had a furnace and evaporative cooler in the mechanical room, connected to supply air ductwork under the floors and return air ductwork above the ceiling in the lobby and main hallway.

The building is served by a municipal sewer system. There is no fire suppression system.

The building has had many alterations over the years. Although some of the modifications are minor, major modifications include enclosure of the front and rear portals with wood framing and windows, the creation of an office under a portion of the rear portal, enlargement and remodeling of the restrooms and mechanical room, addition of a fireplace in the lobby, accessibility modifications, and roofing over of the trellis on the southeast. The entire building has been covered with standing seam metal roofing; but it is not obvious if the original built-up roof is still there.

The mechanical and electrical systems have been incrementally modified over the years, as well. The heating system now has two gas-fired furnaces, tied into the original heating and cooling ductwork. In addition, three evaporative coolers have been installed on the roof, connected to ductwork in the attic, which supplies different “zones.”

The building has been tested for asbestos floor tiles.

92 Detailed Project Description

There are two layers, one carpet and the other asbestos tiles in the Admin office. The top layer was installed in 1980 over the existing asbestos tile and mastic. Both layers are damaged and required removal for new carpet tiles. The original tile and mastic (Flintkote Classic XI) are damaged and presents an indoor air quality hazard.

Primary factors to consider will be that the existing asbestos floor tiles will be replaced with new carpet tile floors and vinyl cove base at later date. The new construction will fit sensitively into the existing building and materials will require little maintenance and be of durable construction techniques. Electrical utility is available at the Visitor Center and is to be provided.
