About this file
This document is a set of construction design details and specifications for landscape and site improvement work, specifically for Camp 5 and Carter Pond Access Improvements at Dulles. The drawings are prepared by Alpha Corporation (21000 Atlantic Blvd, S. 400) and referenced as project N:\JOBS\DULLES\572-100-C.
The specifications detail requirements for tree planting, wayside post installation, and retaining wall construction. Tree planting specifications require a minimum 12-inch diameter root ball, placement with 1.5 inches of the root ball above finished grade, removal of burlap and wire baskets with specific cutting procedures, use of planting soil mix and 2-inch mulch per specification, and stabilization using three 2x2 hardwood stakes with green webbed arbor tie tape and white surveyor's tape. Prune dead or damaged limbs; if natural tree shape is compromised, replace the tree without cutting the leader. Wayside post installation requires 4,000 PSI concrete footing per specification section 03 30 00 "Cast-in-Place Concrete," with minimum 6 inches of concrete around the post and 3 feet minimum depth. The retaining wall specifications reference typical section details with specific construction methods for the stone wall construction. The document includes plan views, elevation details, and photographs showing existing stone wall conditions and installation examples. Drawing revisions are dated 8/27/24, 9/16/24, 10/4/24, and 11/1/24.
