The contracts cover enabling works, construction of the running tunnels, and initial station construction, including piling and utility diversions.
Crossrail awarded a total of 65 contracts covering construction of the line, which is now 85 per cent complete. Work on station construction and tunnel fit-out is still under way, with 21 contracts still to complete.
Parts of the Elizabeth line are scheduled to open in December 2018, ahead of the east-west route becoming fully operational by the end of 2019.
Large contract overruns include the Eastern Running Tunnels contract awarded to a JV between Dragados and John Sisk, which was initially valued at € 531m but reached a final cost of € 838m.
The Western Running Tunnels and Bond Street / Tottenham Court Road SCL contract awarded to the JV between Bam, Ferrovial and Kier (BFK) rose from an initial € 523m to € 825m.
Another contract at Bond Street, the Bond Street station (piling & dwall), undertaken by a JV between Costain and Skanska, was valued at € 37m when awarded but ended up costing € 106m once completed in January 2014.
The main works at Paddington Integration undertaken by Carillion also ballooned from € 31m to € 109m during the course of the project.
In a statement accompanying the release of the information, Crossrail said: “None of the major Crossrail tier one contracts were awarded as fixed-price contracts covering 100 per cent of the scope, design and cost, and therefore it was never anticipated that these contracts would be completed for the award price.
“The contract value at award does not reflect the risks that were retained by Crossrail Limited and contingency was allocated for this. The actual costs of these works are in line with Crossrail Limited's initial estimates.”
Despite the overruns, the cost of the line still fell below the € 16bn funding envelope for the project, which was reduced from an initial € 18bn funding package approved in 2007.
