The total value of engineering construction work done across the different sectors during the past 15 years is shown in graph 19.13. The value of public sector engineering construction work done has remained relatively constant from 1988 to 2002. Over the past five years the private sector has demonstrated increased volatility and by the end of 2002 was of greater value than public engineering construction.
Table 19.14 illustrates in more detail the contribution of public and private sectors to engineering construction work done. In 2001 the value of work done for the private sector contributed 38% to total engineering construction work done. This share increased to 51% in 2002.
In 2002, 24% of the total value of work engineering construction done was attributable to roads, highways and subdivisions followed by oil, gas, coal and other minerals (21%) and telecommunications (14%). The value of work done in oil, gas, coal and other minerals increased by 147% to $4,657m between 2001 and 2002.
