Crossrail’s construction is running 20 per cent over budget this financial year, according to Transport for London papers, but the scheme is “still forecast to be delivered within its overall funding”.
The TfL Finance Committee papers showed that Crossrail has overspent by £190m for the year to 30 March, as of 6 January.
Of that, there was a £19m overspend in the four weeks to 6 January – the most recent reporting period.
It put this down to factors including the need for more staff, as well as changes in both the scope and design of system-wide main works.
TfL said Whitechapel station and Farringdon station works were completed later than expected, and there were delays to work at Woolwich and Bond Street stations.
BBMV (Balfour Beatty, Morgan Sindall and Vinci) is the main contractor on Whitechapel, while a joint venture of Bam Nuttall, Ferrovial and Kier is working on Farringdon.
Balfour Beatty is the contractor for Woolwich station (pictured) and a Costain Skanska JV is the main contractor on Bond Street.
Excluding Crossrail, TfL’s capital expenditure is £206m (13 per cent) under budget so far this financial year. Of this, £42m has been saved due to pauses in Jubilee and Northern line upgrades.
In a TfL board paper from 30 January it was revealed that the Crossrail project was 90 per cent complete.
The £14.8bn project is expected to start handing over infrastructure to TfL this summer in order for it to begin operational testing and commissioning.
The opening of the central operating section is expected in December, followed by the Shenfield / Abbey Wood to Paddington link in May 2019 and Shenfield / Abbey Wood to Heathrow / Reading in December 2019.
A Crossrail spokesman said the report referred to actual spending versus forecast spending made in September 2016 and that the programme remained within the £14.8bn overall funding envelope.
