Price not right


I wish to take issue with your statement in Comment (NCE 21 June), that the Jubilee Line budget was unrealistic for political reasons.

The addition of all contract sums awarded, including the train supply contract, came to £1.2bn, according to figures published in the NCE. The £1.8bn budget figure therefore allowed adequate monies to cover land costs, administration and overruns.

The final cost of £3.5bn was due to a number of factors, principally lack of cost control on architectural requirements and a general lack of experience in underground works by the project team.

The Victoria Line cost £70M in the 1960's and with an inflation factor of 20 gives a present day cost of £1.4bn.

Both lines were of similar length.
