Appendix E 6.2 Costing/Contributions
MR identified that section A has an annual routine maintenance allowance of $50 000 (2006 dollars). With development, ESAs will increase by 9% and 82% eastbound and westbound respectively. The development therefore creates a need for a further $22 750 per year (9% x $50 000/2 + 82% x $50 000/2) for routine maintenance during its operational life. In this case, Main Roads and the developer agreed that the requirement for additional routine maintenance would be limited to the first 10 years of operation of the quarry.
After discussions with Main Roads, the developer agreed to pay half of the cost of pavement rehabilitation on section B. This section had no remaining pavement life but would have continued to operate effectively with minimal maintenance in the absence of the development. Using Main Roads unit rates, the full cost of rehabilitating the pavement on section B was estimated at $1.25 million (in 2006 dollars). The developer therefore accepted responsibility for paying $625 000.
MR advised that $1.25 million (in 2010 dollars) was expected to be allocated through the RIP for rehabilitating the pavement on road section C in 2010. Using an outturn factor of 1.00/1.12 extracted from the RIP Guidelines, this is converted to $1.12 million (in 2006 dollars). The cost of bringing this improvement forward from 2006 to 2008 is the responsibility of the developer. MR will need to ensure that the capital cost for the rehabilitation is available in 2008.
The developer paid for the whole cost of upgrading intersection X to an Austroads Type C form at year 2007 ($475 000 in 2006 $).
The developer paid for the cost of construction of the Type A access intersection to the quarry ($150 000 in 2006 $).
