Please take the time to watch this video on Roscon's Facade and Cladding Audits.
Roscon's Cladding and Facade audits comprise of four stages:
Roscon will review all design, construction and approval documents availalble, including original architectural plans, to determine whether Aluminium Composite Panelling (ACP) has been specified for use on the building. If ACP is installed on the building, Roscon will investigate which type of ACP was specified.
Aluminium Composite Panelling can be acquired in three forms:
1. Combustible Core (Polyethylene)
2. Fire Retardant Core
3. Non-combustible Core
To the naked eye, all three types of ACP look the same.
Subsequently, Roscon will carry out a determination of building design, classification, and similar details in accordance with the National Construction Code (NCC). This will be presented to the committee in an easy-to-read report with our findings, and we may recommend proceeding to stages 2 and 3.
Roscon will carry out a site investigation to assess details of the façade panel physically present on site, including how it has been integrated, as well as whether it would be classed as forming part of the structure of the external wall or would be considered an attachment for aesthetic purposes, as different material requirements exist for different scenarios in the NCC. We also document facade details including the type, material, and extent of the cladding.
As part of the audit and report we consider the requirements in the NCC as well as deemed to satisfy provisions. Composite Panel and façade details, the product, manufacturer, and code mark and the building’s fire and ESM systems as well as fire performance solutions. At the conclusion of the report Roscon provides recommendations.
As highlighted at La Crosse Apartments (Docklands) fire, our data suggests that the failure in the system is occurring in the procurement of the product specified. Architects may stipulate a Non-Combustible Core in size ‘6 font’ on the architectural drawings, however builders in trying to reduce costs and increase profits are electing to order the cheaper Combustible Core, as consumer can’t notice the difference until it’s too late.
The imported Combustible cladding installed on the Lacrosse building was tested by the CSIRO and found to be so combustible that the test was abandoned after 93 seconds due to fear that excessive flaming and smoking would damage their testing equipment.
Roscon performs materials testing to AS1530.1 in conjunction with the CSIRO. AS5113-2016 (Fire propagation testing and classification of external walls of buildings) has been introduced by Australian Standards. It is anticipated that this will be incorporated into the NCC and Certification in the next round of changes in May 2018. When incorporated in the NCC, the cladding for new buildings will need to undergo a full-scale facade test to assess the fire safety as applied to a building’s external cladding. The current fire testing standard in Australia - AS1530 - is 23 years old and the prescribed tests do not adequately prescribe a testing regime for modern materials.
The sample size required for the AS 1530.1 test is a cylinder 45mm dia. x 50mm and having a 2mm dia x 25mm deep hole drilled axially from the top of the sample, 6 samples are required per test. The cost of each test from the CSIRO will be passed on as a disbursement. The testing process usually takes between 5-8 weeks.
Roscon’s fees for obtaining the samples from site and providing our expert option based on the sample results are not included in the CSIRO fee. Additionally, any ‘make good’ requirements of ACP where Roscon obtained the samples onsite is not included within our quotation.
Roscon can formulate a plan to remove and rectify any non-conforming ACP immediately by preparing a detailed scope of works and costings for the removal and replacement of the defective external cladding at the property, including a detailed costings report in compliance with VCAT Practice Note No 2.
Roscon has provided expert advice and recommendations to the Senate Committee for Aluminium Composite Panelling. Recently Roscon was invited by the CEO of the Victorian Cladding Taskforce to also provide expert advice and recommendations, making Roscon the industry leading expert in assisting Owners Corporations with Aluminum Composite Paneling.
