How to save time....when your approval involves a Build Over Sewer (BOS) or infrastructure pipe.

Updated: Oct 13, 2021

Building over an Asset (BOA) - does your project include building works or a pool on or near a sewer or stormwater pipe?


According to the legislation - QDC MP 1.4, relevant infrastructure means


“a sewer operated by or for a sewerage service provider

a water main operated by or for a water service provider;

a stormwater drain operated by or for a local government;

a combined sanitary drain.

Note— Relevant infrastructure ceases at the connection point.”


Save time (and keep your certification simple!)

  1. Add detail to plans - pipe/ sewer connections and the distance/ location from work, pipe diameters

  2. Keep the legislation link on your desktop- so you know what's required and when MP1.4 applies

  3. Ensure your pool / building work documentation is in order.

  4. Let BA&A know in initial communication if you require a BOA/ BOS facilitation fee included in your fee proposal.

The build over infrastructure process - building approvals

Your engineer works from the surveyor’s information, looking at

  • drill down report information

  • pipe details

  • location of assets on site

Title search details and/ or CCTV footage of the asset(s) in question may also be required. Then the engineer signs off regarding QDC MP 1.4, if compliant.
