Establish the constraint
Use the existing and future network model to identify the limiting asset and the conditions that cause the shortfall. Confirm whether the problem is capacity, pressure, replenishment, source availability or reliability. Record the applicable utility criteria and their revision.
Test complete servicing options
Include the enabling works that make each option operable: inlet capacity, power, controls, access, land and network connections. Compare lifecycle implications and the effect of asset outages. Consider whether interim operational measures are feasible.
Use triggers and lead times
A staged plan needs a measurable demand or development trigger, enough delivery time and a responsible owner. Maintain a monitoring plan so that the preferred timing can be adjusted as growth and operating evidence change.
Keep the decision traceable
Provide a clear comparison of the baseline, options, assumptions, residual risks and next investigations. Strategic planning documents establish context; detailed project choices need local evidence. Explore the illustrative network augmentation study.
