HC Deb 01 December 1980 vol 995 cc67-8W
Mr. Dudley Smith

asked the Minister of Transport what are the factors used to revalue 1979 survey prices to 1980 survey prices for trunk road construction, trunk road maintenance, local road construction and local road maintenance.

Mr. Fowler

The following factors have been used to revalue these programmes:

1979 Survey Prices to 1980 Survey Prices
Factors
Motorway and trunk road Construction
Roads Output Price Index 1.238
Land Cost Index 1.232
Factors
Local Road Construction
Tender Price Index 1.208
Cost Outturn Index 1.193
Land Cost Index 1.232
Motorway and trunk road Maintenance 1.193
Local Road Maintenance 1.174

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.
