We had Darbecca back out on site again this week for the Pre-Plaster Inspection. Here are the defects that our inspector found that need to be rectified before the plaster can go in.
- I noted several sections to the sisalation paper (reflective insulation) that requires reinstating due to rips, tears and openings.
- I noted that the dwelling is not water tight with the following that have not been installed. • Flashings • Missing roofing sheets to Garage • Missing sisolation • Cladding. The dwelling must be water tight prior to installing any wall batts or plaster.
- The pre-plaster insulation installation has the following defects. • Areas of insulation have been installed over plumbing pipes and timbers. All need to be fitted in a manner that has the batts flat to the plaster backing. • No ceiling batts have been installed under the heater platform/walkway. • There has been excessively wide amount of ceiling insulation left out.
- External door flashing not installed. The timber access doorframes do not have polythene flashings installed under its bottom timber sill.
- I noted the lower staircase timber frame is showing out of alignment to the upper frame by about 20 mm. The alignment of these upper and lower walls is critical to present a flat wall of plaster along the staircase.
- The front timber beam to the balcony area have not been or bolted to the post supporting them using the required bolting method. The “angle brackets currently used do not comply with the AS1684 fixing method.
- A small number of window and door frames are presenting out of plumb in excess of the 4 mm over 2 m tolerance.
- The window reveals and door frames around the dwelling have not been packed as per the manufacturers installation requirements.
- Nogging is missing above bath hob. The bath hob requires noggins around the perimeter to support the plaster and metal waterproofing angle.
- The plumbing water pipes have not been secured with silicone at the frame penetrations. A silicon or simular material must be inserted into each hole to stop water hammer to the plastic pipes.
- The ducted heating air return does not currently present itself to been installed in a manner that is “Air Tight”. This will result in the air return passage being open to the roof space and external air being allowed to enter the dwelling at any time thus the star rating on the dwelling will be compromised. The air return must be sealed in a manner that seals the whole area from the roof space and allows the air intake to perform at its full intake volume without drawing from the roof space.
These along with the 14 outstanding defects from the previous frame inspection now need to be rectified before we can proceed. We have asked to meet on site with our site supervisor to discuss so that will take place at 11am tomorrow.
