HC Deb 30 July 1976 vol 916 cc451-2W
Mr. Cartwright

asked the Minister of Agriculture, Fisheries and Food what is his most recent estimate of the capital costs of constructing the Thames flood barrier; how this compares with the original estimate; and what are the main reasons for the variation.

Mr. Strang

The cost of the Thames flood barrier, at March 1976 prices and excluding the cost of downstream defence works, is expected to be about £158 million. This compares with the estimate of about £88 million made when the designs were completed at the end of 1973. Of the £70 million increase, £60 million is due to wage and price increases over the intervening period. The remaining £10 million is due to modifications and additions to the design.
