asked the Minister of Transport what are the factors used to revalue 1978 survey prices to 1979 survey prices for trunk road construction, trunk road maintenance, local road construction and local road maintenance for each of the years of the period of the forthcoming public expenditure survey.

The following factors have been used to revalue these programmes:

1978 survey prices to 1979 survey prices
Motorway and trunk road construction:
Roads output price index1·092
Land cost index1·296
Local Road Construction:
Tender price index1·165
Cost outturn index1·089
Land cost index1·296
Motorway and trunk road maintenance1·089
Local Road Maintenance1·112
Because the mix of expenditure between land, work in progress and new works, varies from year to year, the overall effect of the revaluation can differ as between one year and another even though the same underlying factors have been used.

his Department's pre-tender estimates of the prices for each trunk road contract let so far in 1979, together with the actual price of the accepted tender.
