ATTACHMENT 1 – STATEMENT OF WORK

PHOENIX AREA OFFICE

Parking lot Stabilized Decomposed Granite

I. BACKGROUND

The Bureau of Reclamation Phoenix Area Office currently has 18,675 square feet of ¼” minus decomposed granite (DG) surfacing. Most of the surfacing is under shade canopies with a +/- 8’1” clearance. The existing material was installed between 2004-2005 and has had minimal maintenance during its lifetime. Erosion has been concentrated to where the shade canopies end and rains have dripped onto the surface, eroding the decomposed granite as deep as 3 inches in places.

II. SCOPE OF WORK

The contractor shall provide all resources necessary to accomplish the task and deliverables described in this Statement of Work. The principle components of work to be performed includes, but is not limited to the following:

1. Removal and offsite disposal of existing decomposed granite pavement section (LS)

2. Installation of 4” thick layer of stabilized DG (Approx. 17,965 sq.ft.)

3. Installation of 80mm stone paving. (Approx. 710 sq.ft.)

4. Removal & reinstallation of existing raised parking space markers (LS)

5. Removal and reapplication of 5 handicap markings with government furnished stencil and paint. Concrete pads shall be salvaged. (LS)
