Before we commence Scoping stage activities, you will need to provide the relevant critical project criteria evidence for us to assess the criticality of your project.

Please refer to our facilitating timely connection of critical customer projects Guideline for more information on what's required.

Concept design & estimate

We will then develop the Concept Design scope maturity, supported by relevant documents and drawings for the selected connection option, to a level that’s appropriate to the class of estimate requested. We will prepare a AACE Class 4** or Class 3** cost estimate for the technical solution required to modify the network to meet the requirements of the customer’s Connection Application.

A Project Scoping Report will be prepared and issued to the customer, detailing the concept design scope of work, cost estimate and an estimated timeframe for delivery of the selected option. 

Design Options Estimate Accuracy Range* Key Driver Indicative Costs* Indicative Timings*
Concept Design with Class 4 Estimate -30% to +50%   Progressing to Access Offer quicker with less cost/time/scope certainty   $75,000 - $350,000 (excluding GST) 16 - 24 weeks
OR
Concept Design with Class 3 Estimate -20% to +30% Receiving more cost/time/scope certainty is prioritised over getting to Access Offer quicker   $100,000 - $410,000 18 - 28 weeks
