construction site building 3d model

Ultra-realistic, real-world scale industrial 3D model for Construction site worker training. Photorealistic PBR materials. No stylization, no cartoon look. Optimized for Unity HDRP/URP VR. Correct metric scaling. Clean topology, FBX export. Large under-construction 10-floor reinforced concrete building structure. Height: 45–55 meters. Footprint: 30m x 30m. Generate at full real-world scale in meters. Very large environment model. Structure: Exposed reinforced concrete frame. Visible vertical columns and horizontal slabs. Unfinished floors with rough concrete surfaces. Steel reinforcement bars (rebar) protruding from columns and slabs. Partially built brick walls on some floors. Construction elements: Green safety netting wrapped around upper floors. Yellow tower crane attachment points. Temporary scaffolding structures (metal pipes). Wooden formwork panels on edges. Construction debris piles (sand, cement bags, broken bricks). Color: Concrete grey base. Rust-brown rebar. Green sa
