Introduction

A multi-unit apartment complex in Boronia suffered from widespread building defects, including persistent water ingress, failed balcony waterproofing, deteriorating masonry seals, and inadequate window flashings. The original builder was no longer trading, leaving the Owners Corporation to fund remedial works through special levies. To secure financing and potentially pursue legal recovery, the Corporation needed an independent, court-defensible cost assessment from a qualified quantity surveyor.

 

Our Scope

We provided a full quantum assessment for the complete remedial program, which included:

  • Installing Stramit cladding over existing rendered Dincel walls
  • Resealing all masonry walls with waterproof sealant
  • Removing and replacing balcony doors, windows, and balustrades
  • Installing new head flashings and caulking around all windows and door seals
  • Replacing waterproofing and tiling to all balconies and terraces
  • Installing new concrete hobs to improve drainage
  • Replacing roof plumbing and all downpipes
  • Patching and painting affected ceilings and walls inside apartments
  • Patching damaged masonry walls
  • Removing and reinstating gutters and downpipes

 

Conclusion

Our detailed quantum report provided a line-by-line cost breakdown based on current market rates, material supply, and reasonable contractor margins. The $1.5 million determination gave the Owners Corporation a credible, evidence-based figure to present to financiers, insurers, and potential litigants.

Crucially, the report was prepared to expert witness standards (compliant with the Uniform Civil Procedure Rules and AIQS guidelines), meaning it can be used in VCAT or court proceedings if the Corporation pursues recovery action. With our cost assessment in hand, the Corporation successfully passed a special levy vote, appointed a remedial builder, and commenced works with full cost certainty.
