How builder & developers avoid Council approval when constructing retaining walls:
They often terrace the land to avoid the addition cost of constructing a retaining wall over 1 metre in height. This method of construction would not require Council approval also the need to be designed by a structural engineer.
Inadequate retaining wall construction:
These new retaining walls were built without reinforcing and concrete core filling. The blocks have been held together with plastic clips and glue!
Defective retaining wall, with positive result:
The builder was made aware of the problem, before the buyers proceeded with the purchase. It was rectified by the builder at his expense, not the buyer.
This shows the importance of a detailed report saving a buyer a substantial amount in rectification costs.
