Attachment 4 - Type B-3 - Final Infantry Drive Drawings.pdf

This is a set of Contract Drawings for ASOG Complex Site Improvements at Camp Murray ANGB in Washington State, issued for construction in September 2026 (Project No. ETRD249361). The drawings depict the construction of Infantry Drive to Building B116, a new access road serving the Air Support Operations Group facility.

The project includes comprehensive civil, site, and infrastructure improvements spanning multiple drawing sheets. Civil work encompasses roadway alignments, grading, drainage, and utility coordination for Infantry Drive and associated access roads (Building West Access and Armor Drive). The roadway design features 6 inches of hot mix asphalt pavement over 6 inches of crushed surfacing base course, with cement concrete curb and gutter, sidewalks, and various pavement markings. Storm drainage systems incorporate catch basins, manholes, and corrugated polyethylene pipes, with erosion control measures including silt fence, wattle installation, and bioswale seeding per Department of Ecology standards. Landscape plans specify site preparation, seeding with dry native seed mix, and protection of existing trees. Electrical site improvements include underground ductbank systems with concrete encasement, lighting infrastructure with pole-mounted LED area lights controlled via exterior lighting control stations, and connection to existing electrical distribution. The project also incorporates striping, signage, utility coordination (water, gas, communications), and construction entrance controls. General notes specify contractor responsibility for all utilities, coordination with existing sewer and water infrastructure that must remain in place, protection of existing conditions, and compliance with Camp Murray environmental and operational requirements including bird nesting protections from February through August.
