The subcontractors' have to comply with Australian Standards. RFA Technical have a number of Inspection Test Plans (ITP's) that need to be completed and signed off by the subcontractors.
RFA Technical can provide all the ITP's that need to be completed throughout the construction stages. Openspace will be very beneficial, however it needs to be completed in accordance with the ITP's.
For example, The contractors' need to take diagonal measurements to check if a slab or room is / isn't square. Furthermore, RFA Technical will rely on the PCA inspection being completed and documented in the provided ITP's.
If the PCA picks up any items that need to be rectified before linings the builder/carpenter has to return to site to rectify.
