Statement of Work

1. GENERAL

The National Park Service (NPS) requires spray injection pothole repair services on roadways under the jurisdiction of George Washington Memorial Parkway (GWMP). Roadway deterioration due to deferred timely rehabilitation projects has distressed pavement, causing the formation of potholes. The problem is particularly acute during the winter months where freeze and thaw cycles cause the formation of potholes. During the milder seasons of spring, summer and fall, prolonged rainy spells cause additional potholes.

1.1. Introduction / Scope

A. All areas in which work will be performed are under the jurisdiction of the national park service, national capital region, and George Washington Memorial Parkway.

B. The contractor shall visit and inspect each site to verify the estimated quantities provided by the NPS and the complexities of conducting spray injection pothole repair activities in areas containing high densities of vehicles, pedestrians, and structures, and to obtain a true sense of the work being requested.
