For those interested to know (Niall), I heard back from Troy about the frame inspection report from H&K Ryan. He emailed it back to me and had signed/dated each of the items fixed.
I had also asked Troy if anything could be done with the drainage issue on the north side of the house. The frame report from H&KRyan seemed to indicate that it could be an issue...
Surface Water Drainage: The retention of water from surface run off could have an effect on this dwellings foundation material which in turn could affect the slab to this house inspected.
Best practice is to monitor the flow of surface water and stormwater run off and have the water directed away from the house and then into storm water pipes by a qualified and licensed Plumber & Drainer.
Subject to this Builder’s contract specifications as to what is being allowed for by the way of surface water drainage, (Reference: AS: 2870 Appendix B, B2.3 (a) for site drainage requirements.)
Troy seems to think that there is not an issue with the water...
"Re drainage, unfortunately we can't have any one go in to do any work as you know. Given the recent weather, there is some water sitting around. The house is on piers of uniform bearing, so the water won't affect the structure"
