Routine Glazing Cleaning (2 Days)

  • Scope: Vertical glazing (6,600 sq.m), glass balustrades (300 sq.m), skylight (440 sq.m)
  • Methods: Telescopic poles (G, 1st, 5th) and davit system (2nd-4th)
  • Productivity: ~50 sq.m/worker/hour due to complex facade geometry
  • Manpower: 10 workers for 2 days (16 hours) to clean 7,340 sq.m

Skylight Cleaning Strategy

  • Skylight size: 26m × 17m (440 sq.m) with max 13m cleaning reach
  • Solution: Manual telescopic poles from both sides, no gantry needed
  • Benefits: Reduced O&M, no mechanical systems, better value engineering
  • Eliminates long-term risks of powered equipment maintenance

BMU & Permanent Anchor Assessment

  • Permanent BMU/anchors rejected due to architectural sensitivity
  • Fifth-floor terrace has luxury/ceremonial importance - minimal visual impact needed
  • Temporary davit system provides controlled access without permanent fixtures
  • Conclusion: Current solution is complete, efficient, and low-impact
