Surfacing
Concrete, not asphalt
A deliberate and considered choice was made on surfacing material. Rather than asphalt, the entire hardened area was paved with concrete. The reasoning was straightforward: concrete paving has a service life of over 60 years with no meaningful maintenance requirements, whereas asphalt requires a new wearing course approximately every 7 years. Over the lifetime of a port facility, that difference in maintenance cost and operational disruption is substantial. There is also a drainage advantage. Rainwater naturally permeates a concrete-paved surface, whereas asphalt accumulates standing water, which accelerates surface degradation and further increases maintenance frequency.
Scope
What the expansion delivered
The expansion delivered 33,000 square metres of dedicated vehicle staging area for pre-check-in queuing, and a further 23,000 square metres accommodating two warehouse buildings of 5,120 square metres each. The project also included converting a single-lane roundabout at the site entrance into a double-lane roundabout, improving traffic flow for the increased vehicle volumes the expansion was designed to accommodate.
The project was delivered through public procurement and required close coordination between design, civil works, and the operational requirements of a working harbour that could not afford extended downtime during construction.
Budget
A genuine surprise
The original project budget was $5.6 million. The final cost landed at $5.67 million, a variance of less than 1.3 per cent. For the port owner, this came as a genuine surprise. In their experience, projects of this scale had never been delivered within budget, let alone close to it. Cost overruns of at least double the original estimate had been the norm.
Delivering on budget in a public infrastructure project of this complexity is not something that happens by accident. It is the result of thorough preparation, disciplined procurement, and management that stays close to the numbers throughout execution rather than only at the end.
Total hardened area -- concrete-paved for a 60+ year service life.
Combined floor area of two new storage buildings.

Budget variance -- $5.67 million final cost against a $5.6 million budget.
The expanded facility positions the harbour to absorb continued traffic growth without compromising the efficiency of vessel turnaround or the experience of freight and passenger customers passing through.
