Mitigating Composite Pain

1. What are my reporting requirements 2. Why are we here MCP OVERVIEW 3. Make Safe – Short term 4. Remediation – Cost Mitigation 5. Project Delivery

WHY ARE WE HERE? A Brief History of Combustible Cladding Fires ▪ ACP Flame Spread: Vertical – Up and Down Grenfell Tower ▪ Impacts to Surrounding Structures and Elements London ▪ Chimney Effect ▪ Petrochemical cladding • 24 storey building that burned for 60 hours Lacrosse • Fire fighters onsite in 6 minutes Building • Fire spread quickly up and around external facade of building • Combination of factors resulting in over 80 deaths Melbourne The product eventually identified was a non-compliant • Renovations undertaken in 2016 included installing cladding to the building product ‘ Alucobest ’ which by visual inspection is • An alternate cladding panel was rejected due to cost indistinguishable from other compliant products such as ‘Alucobond Plus’

PROJECT DELIVERY • Short Term Make Safe • Intrusive Investigation • Planning • Design • Material selection • Remediation • Certification

REMEDIATION: Assessment Engage a professional to asses cladding zones: confirm high risk areas and remediation works • Short Term Make Safe Actions / Risk Mitigation • These works are undertaken to mitigate risk associated with potential ignition sources for combustible cladding • Cost Mitigation Activities • Undertake Intrusive investigations of your cladding • What is behind it • What is the substrate condition like Am I able to reuse the subframe system • Are there other non-compliant materials • Assess the condition and performance of: • Thermal insulation • Window performance and condition • • The more background detail you are able to ascertain will facilitate your ability to corral the remedial cost exposure

REMEDIATION: Works Delivery • Where to does my cost exposure lie • Replacement Material Selection: 20-35% Design: 5-10% • Access and Installation: 45-60% • Certification: 5-15% • Delivery Cost Mitigation Activities • Preplanning: • Use the knowledge gained from your earlier investigations • Have a developed scope and specification in place for tender • • Are there other remediation works that could be combined into the programme: ie. Is commercial benefit in improving the underlying Thermal and Acoustic performance of the façade The longer the duration on the site, the more prolonged your risk exposure •

ACCESS SYSTEMS TYPICAL OPTIONS: Mast Climber • Scaffolding • Elevated Work Platforms (EWP) • • Boom lifts • Scissor Lifts Rope Access • • Swing Stage Building Maintenance Units (BMU) •

MATERIAL OPTIONS: DtS Replacement • Solid 3mm or 4mm Solid Aluminium Plate Cladding: AS 1530.1 • High Performance Composites (Honeycomb Core) • Patinated Zinc • Patinated Copper Glassfibre Reinforced Concrete (GRC) •

DESIGN CONTRACTOR ENGAGEMENT CERTIFICATION Design Considerations • Is there Benefit/Requirement in Architectural engagement • Cladding Replacement: visual like for like or alter the architectural aspect • DA considerations: Does a fire order impact on a potential DA application • Does the project quantum warrant 3D modelling Contractor Engagement • Who will manage the process: Tender(s), Project Management, Sub-Contractor Selection • Project Monitoring / Reporting Cycles / Community & Stakeholder Liaison • Works Verification Procedures: Clear and concise, understand the procedure to deal with ‘issues’ Certification and Statutory Submittals • How to minimise your certification processes: Early engagement is key • Clear and defined design verification processes • Material selection: DtS is Recommended / Advised / Counseled / Beseeched
