Kangaroo Island Airport Upgrade Business Case
allowances for construction on the Island. The below table provides a breakdown of
the costs and demonstrates that the major cost items are pavement upgrade and
terminal upgrade. A contingency of 12.5% has also been included as part of the
calculation. Whilst a contingency is included, and highly appropriate for this exercise,
the cost estimates have been prepared after site inspection, and onsite engineering
assessments of the drainage culverts running under the runway. Therefore the costs
are reflective of the known engineering issues at the Kangaroo Island Airport. For a
more detailed break-down of the costs see Appendix D of the Tonkin Consulting report.
