Private Building Appraisal

We decided to get our own appraisal done of the house before the bricks covered too many of the errors that we had discovered. Our SS finds my husband annoying so we thought if we got another qualified builder who is completely objective to make an assessment and present his findings to the SS, then we would be taken seriously. It was the best $440 spent. My husband called the Master Builders' Association to discuss our concerns and they directed us to their list of registered compliance inspectors. We found someone local and arranged a meeting on site with all of us including our SS.
This is what the appraiser found that needed fixing:
-Top plates of steel posts supporting steel beams needed to be welded or bolted to those beams.
-Void under steel supporting post in garage to be filled with non shrink grout
-Installation of hoop iron straps to secure bottom plates of the dwarf walls on the underneath side of lintels over wide span windows and doors to prevent sag of the dwarf walls as windows are not load bearing.
-Installation of dyna bolts to the bottom plate of steel support post at rear of alfresco
-Certification from the engineer that welded extensions to the steel support posts that were
cut too short are structurally adequate.
-Additional timber cleat in frame where stud was cut to allow installation of drain pipe.
-Additional studs of fixing plates to main bathroom
He also verbally advised our SS at the meeting to get the slab levelled in the living room otherwise we will have issues with our floorboards later.
The only thing we couldn't get resolved was the location of the waste plumbing from the upstairs bathrooms. Despite the bathrooms being at the rear of the house, for some reason the plumber ran the waste plumbing from the rear to the front of the house so the noise of water running through those pipes will be heard over our heads when we are downstairs. We were told this cannot be changed so we have asked if we can sound proof the pipes ourselves as the thought of going through the Wisdom estimating dept sends shivers of fear down my spine. The SS was sympathetic on this one as apparently out of the 2 people in estimating, one has resigned and the other one is going on leave. I pity all those people in Admin at the moment.
Anyway no progress on the house this week. Bricks were supposed to be finished and roof on but no one has been on site. Apparently the roof company didn't get our colorbond roof sheets cut on time.
