When specifying The Building Agency Cladding Systems, it is important that the specified fixing system and ACP panel is suitable for the intended site and building.

Within our scope:  Where the intended use of The Building Agency Cladding System falls within our defined scope and where all details are in accordance with the TBA fixing system, then all plans and specifications may be completed by a designer with the appropriate license class.

Outside our scope: Where the intended use of The Building Agency Cladding System falls outside our defined scope, or where details other than those provided by TBA are being used, then a façade engineer is required to establish compliance with all relevant provisions of the NZ Building Code.
