Maritime Infrastructure development and management
Infrastructure development and management involves ensuring and facilitating the development and management of infrastructure to support the provision and use of transport services.

A key linkage exists between transport infrastructure and the growth of Western Australia’s economy and ongoing economic development.

Measure: Maritime Infrastructure development projects
The Department plays an important role in developing and managing maritime infrastructure.

The Department achieves this through the development of new maritime infrastructure projects.

This measure relates to the development of new maritime infrastructure projects. This work includes the scoping of projects, planning and feasibility studies, stakeholder consultation and project development.

Data shown is the comparative average cost of developing maritime facilities over time calculated by dividing the total operating costs for Maritime infrastructure development by the number of facilities undergoing development.

The variance in expenditure is attributed to carryover expenditure not included in the target.

Measure: Maritime Infrastructure management
The following chart indicates the cost of managing small boat harbours and facilities.

Data shown is the total cost of services for infrastructure management divided by the number of facilities managed in 2002-03, which gives a comparative average cost of managing existing maritime facilities. The Department's boat harbours and facilities are managed on cost recovery principles.

This measure shows total expenditure, not net costs, as it does not include revenue. Many of the facilities included under this output generate revenue.

Measure: Maritime infrastructure management per navigation aid managed
The Department supports the provision and use of maritime transport services through the management of navigation aids.

Data shown is the comparative cost of managing navigation aids, and is calculated by dividing the total maintenance cost by the number of navigation aids.

When read in conjunction with statistics concerning the reliability and performance of navigation aids, this measure gives an overall picture of the Department's performance.

Due to the revised method of allocating internal corporate overheads, no overheads were allocated to this as the maintenance functions for Navigation Aids were outsourced.
