HC Deb 14 December 1978 vol 960 cc330-1W
Mr. Cartwright

asked the Minister of Agriculture, Fisheries and Food what is the estimated additional cost resulting from the Greater London Council's decision to speed up construction of the Thames flood barrier ; and what representations he has received about the safety of the revised construction programme.

Mr. Strang

The Greater London Council's estimates suggested that a shorter construction programme would not involve a net increase in costs. No representations have been made to my right hon. Friend the Minister about the safety of a revised programme.

Mr. Cartwright

asked the Minister of Agriculture, Fisheries and Food what is the latest estimated construction cost of (a) the Thames flood barrier and (b) the associated flood defences as compared with the original estimates.

Mr. Strang

The estimated costs at June 1978 prices and the original estimates given in December 1973 are as follows.

December 1973
(a) Thames barrier £88 million
(b) Associated flood defences £143 million
June 1978
(a) Thames barrier £284 million
(b) Associated flood defences £237 million
