39–43 William Street, Granville

---

Large residential apartment development in Granville experiencing significant waterproofing and building defect issues.

The project was facing:

• ongoing leakage problems 
• dispute escalation 
• commissioner involvement 
• rejected remediation proposals 
• increasing pressure on the developer 

Several previously proposed solutions were considered:

• overly expensive 
• impractical 
• disruptive to the building and occupants 

The developer required:

• technically sound solutions 
• cost-effective remediation 
• coordinated documentation 
• practical implementation pathway 

Green Design Sydney was engaged to assess the building defects and provide practical remediation strategies.

We reviewed:

• existing conditions 
• defect causes 
• proposed rectification approaches 
• compliance and construction implications 

Our role included:

• preparing coordinated documentation 
• developing alternative remediation strategies 
• proposing cost-efficient practical solutions 
• assisting with stakeholder coordination 

• Cost-effective remediation strategy developed 
• Multiple impractical solutions avoided 
• Developer costs significantly reduced 
• Clear technical pathway established 
• Practical implementation approach accepted 

The final outcome provided substantial savings and restored confidence in the remediation process.
