• Wind load on building façade will change impacting on overall façade system integrity.
• Sheeting will require regular maintenance and replacement due to weather damage thus requiring scaffolding to be installed during the complete period of interim cladding solution.
• Majority of plastic sheets (building foils/sarking materials) are not UV stable especially for prolonged term (several months).
• Labour and double handling of materials will increase the cost and the operational impact of the works rather than limiting the works to a short period of replacement based on the permanent availability of replacement materials which is aligned to the WHoG working group endorsement of the CHWC ACP cladding replacement Statement of Requirements (SOR). (SOR is being developed by Arcadis in conjunction with the WHOG working group such that any precedence on CHWC can be applied across all applicable ACT public buildings.
Alternative interim cladding type
• Building facade dynamics will change leading to unintended consequences.
• Installation of interim cladding panels will undermine the fixing areas for permanent replacement panels. The CHWC façade system is not designed for easy removal of panels and damage to secondary support and air seal is likely to happen.
• Acceptable (non-combustible) interim cladding materials in large quantities may change structural support requirements.
• Labour and double handling of materials will increase the cost and the operational impact of the works rather than limiting the works to a short period of replacement based on the permanent availability of replacement materials which is aligned to the WHoG working group endorsement of the CHWC ACP cladding replacement Statement of Requirements (SOR).
