Q. What do I need to do before excavation begins?

A. Do what you can to make the area accessible as possible. If you are unable make sure you let us know ahead of time so we are able to prepare.

Q. Can I build a retaining wall over 1m?

A. Yes you can however once you wall is over 1m Engineering and possible Council Approval will be required (but don't worry we can help with that too). Keep in mind that the wall (if it does not have engineering) is no closer than 1.5 metres to a building or another retaining wall or it does not form part of the fencing for a pool.

Q. How will I know if there are utilities in the area I want excavated?

A. Birkmann Construction will always do a thorough utility search via Dial Before You Dig prior to excavation to ensure no utilities will be damaged.

Q. Do I need Council Approval before commencing a pool excavation?

A. Yes. If you have not lodged a Council Application for the installation of a pool we are more than happy to help. Alternatively you can get in direct contact with our Building Certifier - Adept Building Approvals.
