Custom-Shaped GRC Installation Collision Avoidance Guide: Pre-Assembly, Simulation, and Product Protection System

Four-layer collision avoidance system for custom-shaped GRC: ① detailed prevention — BIM collision check (components vs steel structure / MEP / scaffold conflicts eliminated in advance); ② process simulation — hoisting path and positioning action preview (rotation radius, hover height, worker station); ③ site management — hoist area cordon, transport route planning, components classified and orderly stacked; ④ product protection — installed components corner guards, warning signs, cross-work time isolation. Even repaired collision-damaged components have color difference risks — the cost of prevention is always lower than repair.

Core Points

• Detailed: BIM collision check eliminates conflicts in advance
• Simulation: hoisting path preview (radius / height / station)
• Management: cordon zone + route + orderly stacking
• Protection: corner guards + warning + time isolation

Important Notes

Experience data: 80% of damage to custom-shaped components during installation happens in the "hoisting and temporary storage" stages not the installation itself — manage these two well and loss rate can be compressed from industry common 3%-5% to under 1%.

Custom-shaped GRC component installation collision avoidance system includes detailed stage BIM collision check, hoisting path and positioning simulation, site zone cordon and route management, installed components product protection (corner guards, warning, cross-work isolation) four levels, with the goal of eliminating collision risk before physical work.

Myth: bumps are inevitable, patch up and it's fine. GRC repair has hidden costs: the flexural and weather resistance of the repair location is slightly lower than the parent body, color difference risks emerge over time (patch material hydration history differs), repair traces on exposed surfaces visible under side light. The "zero repair rate" of high-end projects is not OCD, it's dual responsibility for durability and appearance.

Detailed and Simulation: Rehearsal in Digital Space

BIM collision check: integrate GRC divided-panel model, steel structure, MEP pipes, scaffold scheme — spatial conflicts (components vs scaffold cross bars, vs light positions) solved on screen, cost is drawing modification not disassembly; hoisting simulation: animation preview of hoisting path for large and custom-shaped components (lift → translate → rotate → position whole process), check interference with tower crane, cables, installed facades; positioning simulation: worker operation space verification (whether there's wrench space for bolt tightening after component in place).

Site Management: Order Equals Safety

Zone management: hoist radius cordon zone hard isolation (safety officer on duty), non-working hours power-off lock; route planning: component transport route avoids installed areas, turnings with guide personnel; stacking management: components stacked in reverse order of installation (later installed delivered to inside first), battens off the ground, custom-shaped overhang parts individually supported; cross-work: off-peak or physical isolation (protective shed) with coating, welding, glass processes. An orderly site damage rate can be one order of magnitude lower than a chaotic site.

Product Protection: Installation Is Just the Start

Protection measures: external corners and protruding parts wrap corner protection strips (EPS or wood strips + tape, prohibit corrosive tape directly on surface layer), easy-collision heights wrap warning tape; surface protection: sprayed finish surface cover protective film (breathable type, prevent pollution and don't suffocate coating); continuous management: daily inspection log damage risk points, damage recorded immediately (responsibility definition) and professional repair (same-batch material); removal timing: protective materials uniformly removed before completion acceptance and final cleaning. Qinglong's in-house installation team's product protection list management — the last mile of delivery quality.

Comprehensive Comparison

• Digital prevention: BIM collision + hoisting simulation (zero cost eliminate big risk)
• Site order: cordon + route + orderly stacking
• Product protection: corner guard + protective film + inspection log
• Target loss: ≤ 1% (industry common 3%-5%)

FAQ

Q: What to note for components stored on site?

A: Off-ground padding, classified stacking (not exceeding specified layers), rain and sun protection (covering), custom-shaped parts anti-deformation support, FIFO.

Q: Bumped component repair or replace?

Exposed load-bearing parts damage prioritize replacement; hidden non-load parts can be professionally repaired — judgment criteria written in contract to avoid on-site argument.
