construction site building 3d model

A hyper-realistic 12-15 floor half-constructed reinforced concrete building under construction, designed for immersive virtual reality walkthrough. The structure should include exposed concrete columns, beams, and slabs with visible steel reinforcement bars (rebar) protruding from columns and floors. Some floors are partially completed while others are skeletal. The building should feature: - Multiple floors with staircases and elevator shafts (open, unfinished) - Scaffolding systems around the exterior and interior edges - Temporary wooden formwork and metal supports (shuttering) - Construction materials scattered across floors such as cement bags, bricks, steel rods, pipes, and wooden planks - Safety hazards like open edges without railings, broken planks, exposed wiring, hanging cables, puddles of water, uneven surfaces, and debris - Construction equipment such as wheelbarrows, ladders, safety helmets, and toolkits placed randomly - Realistic textures: rough concrete, rusted steel, dusty surfaces, dirt, s
