The State Government (via the Kangaroo Island Futures Authority) undertook a series of reviews to determine appropriate strategies for the future development of Kangaroo Island. The potential for increased visitation, particularly by overseas and interstate tourists, was recognised as a major component of future local economic activity. As Kingscote Airport is one of only two major points of entry onto Kangaroo Island, the other being ferry services, the efficiency of air services is crucial for future development of and growth in visitation to the Island.
Tonkin Consulting was engaged to undertake engineering investigations into the infrastructure requirements and associated estimated capital costs to upgrade Kingscote Airport for four future development scenarios.
Tonkin Consulting undertook a site investigation to confirm the existing condition of the pavement as well as to better understand the likely infrastructure upgrades associated with each option.
A report was developed to define the infrastructure requirements for the entire landside and airside upgrades and a high-level costing for each of the four future development scenarios. Additionally, for each option indicative layout sketches were produced to visually represent the impact of each scenario.
To provide accurate cost estimates Tonkin Consulting had to produce pavement designs for each design aircraft type of the four scenarios. This was prepared in conjunction with Aerodrome Design. Furthermore, concept designs of the terminal building, car parking facilities, and service upgrades had to be undertaken based on the anticipated number of visitors associated with each design aircraft type as well as security requirements.
The report presented a design layout for each design option showing the proposed design upgrade requirements which formed the basis of the capital cost estimates.
The cost estimates were itemised to provide as much detail as possible and even went to the extent of dividing estimated capital costs into those that would be spent locally (i.e. on Kangaroo Island) and those that would go to the mainland.
