This file is Attachment 3: Diagrams for the CATM Range Lead Cleaning and Servicing contract (B865). It contains five technical diagrams illustrating the layout and components of a Combined Arms Training Facility (CATM) range requiring lead cleaning and servicing work.

Figure 1 presents the overall range layout, identifying key areas including the Shooter's Slab with Firing Positions, Range Floor Slab, Range Exhaust Filter Boxes, Ventilation Fan Filter Boxes, Bullet Bucket Cleaning Sample Locations, Asphalt Pad, and Access Road. The diagram emphasizes that the Shooter's Slab and Range Floor Slab are separate concrete areas with different cleaning and sampling requirements, and notes that no work tasks involve steel bullet deflection plates. Post-work sampling of the asphalt pad must be conducted after removal of protective sheeting used under drums. Figure 2 details the Ventilation Fan Filter Boxes, showing cartridge filters, filter box structure, air intake, exhaust duct, slide-out access, fan duct connection, and access door. Figure 3 illustrates Range Exhaust Filter Boxes, identifying the ventilation exhaust port, safety cut-off switch handle, fan motor assembly, filter box access door with spring-loaded fasteners, filter access door, wipe sample location, filter box, circular ducting to manifold, and ventilation components. Figure 4 depicts Bullet Bucket Access Panels and Hoppers, showing retaining pins, access doors, gate bars, hoppers, bullet buckets (50 positions), and debris collection chambers. Figure 5 provides Shooter's Slab and Range Slab layouts with wipe sampling locations marked as positions ①②③ for the Shooter's Slab and A B for the Range Slab, including the 25-meter target reference, in-floor drain, and directional guidance for moving liquids when cleaning the Range Slab.
