Productivity levels, software glitches and Bond Street continue to put question mark over railway鈥檚 final cost

The chairman of Crossrail has admitted the scheme could be another six months late and need a further 拢400m to finish it off.

Tony Meggs told the latest board meeting of Transport for London, which is helping bankroll the job, that Crossrail鈥檚 own scenario modelling 鈥渟eems to support the possibility of a four to six month delay and a 拢300m to 拢400m overrun鈥.

The railway had been due to open last December and was supposed to have an original budget of 拢14.8bn.

But the scheme now won鈥檛 be open until some time between next October and the following March and has ballooned in cost to 拢17.8bn.

Meggs said there was a 20% chance the scheme could be 拢394m over budget and six months late but he told last week鈥檚 TfL meeting that internal probabilistic modelling 鈥 or cost estimates 鈥 meant a 拢42m overspend was currently the most likely scenario.

He added that it expected to get this figure down to zero, telling board members: 鈥淭here is a lot of opportunity to manage our costs down to within the [拢17.8bn] cost envelope. There is a tremendous focus on making sure we do not have to ask for more money.鈥

Software issues associated with the railway鈥檚 complex signalling system, the productivity of contractors and the ongoing delays at Bond Street 鈥 Crossrail chief executive Mark Wild has already said this will only open after the rest of the central section is up and running 鈥 were the main reasons for the uncertainty over costs, Meggs added.

He said the productivity of its contractors 鈥渞emains disappointing and is one of our biggest risks鈥 鈥 and added that Bond Street, being built by a Costain-Skanska joint venture, was giving Crossrail bosses a huge headache. 

This is despite resources being thrown at the job, with 500 staff working around the clock to get it ready enough so trains can pass through it, as part of the trial running of trains Crossrail needs to complete before the line can open.

He added: 鈥淏ond Street remains a challenge for us. We are taking special measures there but we are still not in the clear, in terms of making sure we have Bond Street ready for the start of trial running in the first quarter of next year.

鈥淥bviously even if the station is not completed 鈥 which it won鈥檛 be 鈥 we have to make sure it is open for safety evacuation.鈥

Over the summer Crossrail brought in a new management team for the job which a project spokesman said was to ensure 鈥淏ond Street reaches a sufficient level of readiness to support the start of trial running in the first quarter of 2020鈥.
