Transport infrastructure
Table 3.1
Table 3.1 provides estimates of engineering construction work done on transport
infrastructure by both private and public sector organisations. Estimates exclude
the cost of land; the cost of repair and maintenance activity; the construction of
buildings; the value of transfers of existing assets; the value of installed machinery
and equipment not integral to the structure; and expenses for relocation of utility
services. Estimates for the construction of airport runways are included in the roads
and bridges measure.
Statistics are provided for the sector providing engineering construction services
and the sector that is expected to own the project at the time of completion. Thus,
statistics for work done by the private sector for the public sector summarise the work
done by the private sector engineering construction companies on projects that are
owned by the public sector at the time of completion. When a project is undertaken
as a Private Public Partnership (PPP) or similar arrangement, it is classified according
to the expected ownership of the project at completion. PPPs may be classified as
private sector even if ownership eventually resides with the public sector.
ABS provides both current price and chain volume measures for the value of
engineering construction work done by the private sector for the private sector;
by the private sector for the public sector; and by the public sector. Deflators for
these chain volume measures were calculated by BITRE and applied to estimates for
transport construction to create approximate volume adjusted estimates for transport
engineering construction.
Table 3.2
BITRE regularly prepares estimates of road expenditure sourced from unpublished
ABS Government Finance Statistics (GFS) and internal Department of Infrastructure,
Transport, Regional Development and Local Government data. There have been a
number of methodological changes in the compilation of estimates over time, with
the most significant being the ABS adoption of accrual based accounting for GFS in
1998–99. In addition, data are subject to revision as non-road related expenditures
are identified. Estimates include private road related expenditure from 1998–99
onwards.
Data provided are estimates of expenditure on roads by each level of government
from their own sources rather than the total expenditure on roads by that level of
government. Commonwealth and state estimates of expenditure may include grants
to other levels of government for expenditure on roads.
Estimates are presented at constant 2006–07 prices calculated using the BITRE Road
Construction and Maintenance Price Index.
