Stormwater OSD Weir Construction – Northmead

OSD Construction - Stormwater Sydney

Occupancy Certificate rejected by Certifier due to stormwater requirements not being met.

The premise was a newly built commercial development in Northmead with an onsite stormwater detention tank (OSD). The OSD was not built to the design plan which required the construction of a weir within the tank and so was not certified by the engineers. To obtain an occupancy certificate for the client’s development, Stormwater Sydney was contracted to get the OSD back to specification. The weir is used as the mechanism for slowing the rate of water runoff leaving the OSD tank through an outlet. This is to prevent flooding of public and council stormwater ways during rain events.

Weir Design Plan Requirements

We confirmed the requirements of engineers to the supplied design plans which contained the approved design specifications for the weir. We then constructed the weir as per the original design plans. We provided a certificate of compliance and works report to the Client, then forwarded to both the Engineer and Certifier. The end result was that the stormwater component was recognised as compliant and the Occupancy Certificate issued by the Certifier.

Remediation

We are often requested to undertake remediation works after other trades have not completed the work to the approved design. While it is best that the original trade completes the work, it is often outside their skill set. Prior to any work, that the trades understand the approved design and work to provide this. Many trades accept a job and commence to do it their way. Which might look good but is unlikely to gain acceptance by your Engineer or Certifier. Contact Stormwater Sydney if you struggle with builders or plumbers not completing your stormwater requirements or meeting design plans. We provide fast and effective rectification to get your developments certified and to achieve occupancy.
