Pit and pipe build process
What are pit and pipe works?
Pit and pipe works is one of the ways the nbn™ access network can be delivered to your development. Developments that require pit and pipes have more than three premises. These works include the pits, pipes and conduits, and are typically needed for Single Dwelling Units (SDU), super lots, Horizontal Multi Dwelling Units (Horizontal MDU) and Hybrid Multi Dwelling Units (Hybrid MDU).
nbn will assess your eligibility to receive the nbn™ network using the details submitted online. Qualified applications are sent a developer agreement which would specify which sites require nbn™ infrastructure and costs. If your development is eligible, log in to the nbn™ New Developments Portal and submit your plan to ensure that your application proceeds.
Design and build checklist
The developer or their representative is responsible for designing and building the pit and pipe works according to nbn™ access network guidelines.
For all of your development stages, you will need to:
- Design the pit and pipe works according to nbn guidelines (as outlined in the Deployment of nbn™ pit and conduit network guide). For Horizontal MDU, you can also refer to the Horizontal MDU pit and pipe guidelines.
- Submit a pre-construct design for nbn to review and remediate if any changes are required.
- Build pit and pipe works in accordance with your approved pre-construct design and the nbn™ access network guidelines (as outlined in the Deployment of nbn™ pit and conduit network guide) and the pit lid descriptor. You can choose your own supplier or refer to the pit and pipe supplier list. For Horizontal MDU, you can also refer to the Horizontal MDU pit and pipe guidelines.
- Submit your as-built design and Notice of Practical Completion (PCN) for nbn to review and remediate if any changes are required.
- Read and complete the as-built design and PCN checklists before submitting as-built design and the PCN.
- Ideally, at the 'frame stage', submit a Network Termination Device (NTD) pre-installation request to ensure newly built premises are ready for activation of nbn™ services (recommended).
- Advise builders to supply the in-home cabling for the nbn™ access network.
If there are no issues with the pit and pipe works, nbn will issue you with your Certificate of Practical Completion and will organise the installation of the nbn™ access network to your development stage.
It is nbn's responsibility to install the nbn™ access network. Once nbn receives your as-built designs and PCN, nbn will organise a site inspection. As part of the PCN, you will need to transfer ownership of the pit and pipe works free of all encumbrances. For Horizontal MDU, as part of the PCN, you will need to grant a licence to nbn for the exclusive use of any pit and pipe works that are free of all encumbrances.
nbn will install a local network conduit on the street of your development that can be connected to the building entry point of the premises in your development. The installation will be completed with the aim to meet the estimated premises occupation date as provided by you. Once complete, nbn will send you a notice that the site is in service.
Residents can connect to an nbn™ powered plan through their preferred phone and internet provider.
Developers and/or their pit and pipe contractors need to adhere to CAD Standards and Symbols Specifications when drafting pit and pipe designs. If you are unsure, the Assisted Drafting Tool (ADT) is available for download.
In-home cabling for the nbn™ access network for your nominated technology must be done by registered cablers using nbn standards and guidelines.
