Forest Bunker Construction Site

Undisturbed woodland before construction. No visible bunker. Dense pine needle ground cover, exposed roots, scattered rocks, untouched terrain with slight depression where future entrance will be built.SCENE LOCK: Static tripod camera at exact same position, natural 35mm lens feel, identical framing and forest landmarks. Twin moss boulders, center pine tree, fern clusters, and entrance alignment remain fixed. STAGE: Active underground bunker construction. Excavation complete, reinforced concrete entrance shaft being built. Workers in PPE installing forms, rebar, waterproofing systems, drainage lines, and structural framing. DETAILS: Excavator parked nearby, rebar cages, concrete forms, scaffolding, generators, extension cords, safety cones, dirt piles, wheelbarrows, realistic mud tracks, construction lighting, workers physically performing tasks, accurate underground build sequence. NEGATIVE: no text, logos, watermarks, warped geometry, floating tools, instant completion, impossible machinery positions, changing forest layout, teleporting materials, unrealistic construction methods. DETAILS: Survey stakes, faint spray-paint utility markings, measuring tape on ground, small tool bags, realistic forest debris, natural shadows through trees, footprints from survey crew. NEGATIVE: no text, logos, watermarks, warped geometry, extra trees, new landmarks, floating objects, impossible lighting, futuristic machinery, teleporting construction elements, visible bunker entrance.
