Please see response below;
can someone please answer the following questions regarding onsite stormwater detention system.
How much does it cost to get the Hydraulic plans done for onsite stormwater detention system, do we have to go through the builders for this or can we get this done on our own.
We have been quoted $ 3000 for the drawings and report by the engineer and $46000 for construction of a 27.5 cubic meters of underground tank (under the driveway) and plumbing from this to the council drains on the street.
It was shocking to find such a large amount being required after the whole tender process bank loans had been finalised. Please help us by giving advice and sharing your experiences.
