Key information for builders and developers: Fibre ready pit and pipe for nbnTM New Developments Horizontal Multi Dwelling Units (HMDU)

Dwelling preparation requirements are to assist with the installation of the nbn™ access network technology being installed to the dwelling.

• 1 x internal P20 nominal rigid white telecommunications conduitinstalled from the nbn™ utility box, electrical enclosure location toa suitable location within the dwelling (see Figures 9 and 10).

• Dwellings constructed on new lots, HMDUs or that are streetfacing will require a lead-in. For an example of a lead-in seeFigure 9.

• Street frontage dwellings would require the lead-in fromthe dwellings proposed nbn™ utility box, electrical enclosurelocation, to the property’s front boundary closest to an nbn™pit.

• Where the dwelling/s are located within an HMDU the lead-inwould be installed from an internal pit (see Figures 13, 14and 16) to the dwellings proposed nbn™ utility box, electricalenclosure location. Do not exceed the pits conduit or lead-incapacity (see Figure 4).

• The lead-in conduit at the building entry point can beinstalled within the dwelling footings and exit the wall cavityat the proposed nbn™ utility box location, electrical enclosurelocation or the lead-in can be surface mounted over thedwelling footings and up the external wall to the proposednbn™ utility box, electrical enclosure location. See Figures 1and 2.

• Pit types available for selection: type 2, type 5, type 6, type 8. Allpits to contain pit lid gaskets. All pit lids to be branded NBN asper NBN-TE-CTO-194.

• Conduit entry into pits is important; good examples are shown inFigures 5, 6 and 7. Do not install conduits into the longest side ofa pit Figure 8.

• No more than two 300mm radius 90° underground bends fromthe pit to the nbn™ utility box location and one aboveground100mm radius 90° bend can be used between draw points. Amaximum of three bends in total. See Figure 1, 2, 9 and 10.

• All conduit fittings and joins must be glued using solventcement.

• Lead-in conduits installed into the dwelling footings rising upinto the wall cavity must not terminate in the wall cavity; theconduit must exit the wall cavity using a 100mm radius 90° bendunbroken as per Figure 3. Any lead-in conduit terminating withinthe wall cavity should be discarded. Lead-in conduits terminatingwithin a wall cavity could allow the ingress of water, moisture orinsects into the wall cavity.

• In this case the lead-in must be intercepted before thefootings and redirected as surface conduit to the nbn™ utilitybox, electrical enclosure location. For an example of a surfacemounted lead-in see Figure 4.

• Flexible conduit must not be used underground, or in wall orceiling cavities.

• It is the developer / builder’s responsibility to ensure where thebuilding entry point is lower than the street conduit a drainagepit may be required near the dwelling.

Key information for builders and developers:Fibre ready pit and pipe for nbnTM New Developments Horizontal Multi Dwelling Unit (HMDU)This document should be read in conjunction with the following documents for new developments pit and pipe requirements:

• NBN-TE-CTO-194: New developments deployment of thenbn™ pit and conduit access network.

• NBN-DES-STD-0011: Preparation and Installation Guide -SDUs and MDUs.

• G645 Communications Alliance Ltd: Fibre-ready Pit and PipeSpecifications for Real Estate Development Projects.

Important items to remember:

All new lots or subdivided existing lots require fibre ready facilities (pit and pipe). All P100 and P50 conduit must be roped. P20 conduit must be strung and tagged. All conduit entering pits must be fitted with the appropriate sized bush. All conduits shall be plugged as per NBN-TE-CTO-194. This could be in the form of internal reticulated pit and pipe with service drop conduits; generally in Horizontal Multi Dwelling Unit sites (HMDU) are 4 units / townhouses or more.

• HMDU internal reticulated conduit between pits for 3 to 24units / townhouses shall be P50. See Figure 3 for all conduitdimensions.

• HMDU internal reticulated conduit between pits for 25 ormore units / townhouses shall be P100.

• The developer is responsible for installing any new pitand pipe externally in the road reserve where the newlot/s are street facing, this pit and pipe must interconnectto the internal pit and pipe servicing the internal units /townhouses. See Figures 11, 13 and 17.

• Where existing suitable carrier network pit and pipe exists,any pits and service drop conduits requiring installation overthe existing network to service the development and or anystreet fronting units / townhouses will be funded by thedeveloper. See Figures 12, 14, 15, 16 and 18.

Note: Not all HMDU unit / townhouse pit and pipe configurations are represented; Figures 11 through 18 are examples only.
