Building around the Nation – Updated Builder Guidelines


Welcome to issue #4 of the new developments eNews. eNews seeks to provide developers and builders with an awareness of the requirements for supporting their new developments with NBN fibre.

As we roll out optical fibre to new developments around the country, the diversity of housing construction has prompted a number of updates to our Builder guidelines.   These updates reflect the challenges of high ambient heat in some parts of the country through to NBN equipment installation in designated Flood Hazard Areas. The revised document, titled Residential Preparation and Installation Guide: SDUs and MDUs v6.0 (which replaces the NBN Co Preparation and Installation Guide:  SDUs and MDUs v5.0), covers installation in both single premises lots and smaller multi premises lots.  Key changes in the document include:

  • Simplified spatial reservations for NBN equipment, with guidelines for horizontal or vertical layout - Section 4.3
  • Separations for the PCD from gas regulators have increased, and more information is provided to improve conduit placement - Section 3.
  • Following a number of representations from enclosure manufacturers, specifications for the enclosures (including builder constructed cabinets) have been released to ensure adequate gas and thermal ventilation. Builders now have additional choices to provide locations for the equipment - Section 4.4
  • New requirements for equipment location in Flood Hazard Areas (reflecting recent ABCB standards) -Section 4.2.

New Master Developer Agreement (MDA) Update

Following Developer feedback on the need to streamline the approval of development applications, we are pleased to advise that next month we will release a new Master Developer Agreement (MDA).

With the release of the MDA, the current Developer Application Form will be split into two forms:

  • Form 1: Registration of the overall Development to receive the Master Developer Agreement; and
  • Form 2: Registration of subsequent development stages within that overall development.

More details on the new MDA will be released prior to launch date, mid April 2013. Stay tuned!

In-Service Developments Shown on Rollout Maps

NBN Co's online rollout maps have been enhanced to display areas within new developments that have gone 'in-service', replacing the previous pin marker. This change will assist residents in these estates who can now enter their address and get confirmation that they have an NBN service available.

The rollout maps display the different stages of construction on the NBN - towns that have NBN services available; suburbs where construction has already commenced; the areas in Australia where construction of the NBN will commence within one and three years; and now new development areas that are in-service.

Ventilation Requirements of NBN Co Equipment

Like all electronic appliances, NBN Co's NTD, PSU and other end user devices consume energy. This energy is dissipated as heat.

When installed into a closed enclosure or space, the combined energy dissipated by NBN Co's and the end user's electronics (such as a Wi-Fi device) accumulates and causes the ambient temperature of the surrounding air to rise. If the warm air is trapped and cannot easily escape, the operating temperature of the electronic devices can increase significantly.

Operating temperature is important because there is a relationship between long term average operating temperature and equipment failure rates. In general, failure rates approximately double for every ten degree rise in long term average temperature. Optimising an enclosure's thermal properties reduces failures, which reduces end user inconvenience, lost productivity and reduces the cost of managing failures and restoring services.

For these reasons, the design of an Open Enclosure or Home Distributor should be carefully optimised to take advantage of convection cooling. Convection currents established in the surrounding air can carry warmth away from the equipment, minimising temperature rise of the electronics. Effective convection requires enclosures to be thermally ventilated.

NBN Co requires Open Enclosures and Home Distributors to be thermally ventilated. All requirements are stated in the NBN Co Residential Preparation and Installation Guide: SDUs and MDUs. Ventilation requirements have been specified in NBN Co's Preparation and Installation Guide to ensure adequate free flow of air in and out of Open Enclosures or Home Distributors.

Connecting Homes – NBN Equipment Pre-Installation

For a smooth and efficient connection to high-speed broadband for your customers, builders should arrange pre installation of the in-home equipment supporting NBN access. This approach minimises disruption to residents moving into these homes, reduces the risk and cost of any remediation work, and simplifies Developer project and site management activities.

At lock up stage, once the conduit path has been completed, all homes should be booked in with NBN Co for in-home equipment installation. Equipment installation should occur at least 10 days prior to occupation so that once residents have moved in they can contact their preferred RSP to get connected to the NBN. (The NTD pre-install process is only available at Developments where NBN Co. has been engaged to supply fibre).

All you need to do is call 1800 OUR NBN (1800 687 626) to request a 'NTD Pre-Install' and make an appointment. Please ensure you have the following ready when you call:

  • Premises address or addresses
  • Development estate name
  • Confirmation that power is available
  • Date by which the premises will be at secure stage
  • Expected premises completion or handover date
  • Preferred installation date

You will receive a notice to confirm the pre-installation date.

Find a Service Provider Online Enhancement

A new search feature has been recently released to enable end users who live in an estate where the NBN is available to find service providers in their area.

The new Find a Service Provider page allows end users to search for their location to see if NBN services are available at their home or business address. If the address searched is in an active NBN fibre or fixed wireless area, the end user will be given a list of all active service providers offering NBN services at that location.
