The authorities and HS2 understood the brand new high speed railway was over budget and was probably behind program years ago, documents seen by the BBC series.
The files were composed in 2016, until MPs had signed off the first stage of the project.
It is evidence that both people and Parliament were not given the entire picture about the real cost.
The Department for Transport said:”Like all important, complicated projects delivery plans evolve over time.”
“We often maintain Parliament and members of the public updated on the progress of the project,” that the DfT added.
It’s funded by the citizen.
The lineup was expected to be constructed in two phases, beginning with a new railroad linking London and the West Midlands.
Stage one of this development was expected to open in the end of 2026, together with the second phase scheduled for completion from 2032-33.
In general, the railway was designed to price #55.7bn.
Before this month, the authorities said it intended to review the costs and benefits of the rail project, with a”venture or no-go” decision by the end of the year.
Just last month, the Transport Minister, Nusrat Ghani MP, who’s presently a government whip, informed Parliament”confidently” the programme could be delivered on budget and on time.
“There is just 1 budget for HS2 also it’s #55.7bn,” she said.
However, the documents obtained by BBC News show that at least three years ago the government and HS2 knew that was not the case.
Back in May 2016, then Chancellor George Osborne received a letter from Patrick McLoughlin, the Transport Secretary in the moment, where he confessed that the initial stretch of the railroad was a billion pounds over funding.
Nevertheless a former HS2 manager told the BBC that the 1bn overspend was considered, at the time, to be”a very conservative estimate”.
“Internally the groups knew it had been a whole lot higher than that,” he added.
The 1bn overspend is simpler than it initially sounds because it did not include a realistic quote for how much the property and land needed to build the railroad would price.
The quote for property and land which HS2 was using in the time for its London-Birmingham stretch was #2.8bn.
The consultancy company PwC discovered that”fundamental parts” of the quote had been calculated in an”ad-hoc manner”, as shown by a report seen from the BBC.
And two senior figures that worked in the Land and Property division in HS2 in August 2015 into April 2016 calculated , in fact, the true cost was 4.8bn.
That would have added a further #2bn, taking the total overspend in the time on phase one of the project to at least #3bn.
Stage one delay
The May 2016 letter to George Osborne also indicates a one-year delay to the opening of phase one was currently being considered because it could”bring cost savings”.
Cost was, at the voice of the then transport secretary,”a more substantial challenge”.
The correspondence also shows that, at the moment, HS2 failed a crucial hurdle named Review Point One.
According to some former HS2 director that”was just like saying it was not fit for purpose”.
The BBC has also acquired a Department for Transport briefing note labelled as”confidential”, composed in December 2016.
The document acknowledges that despite planned savings”that a substantial gap to target cost will remain”.
And it says, following alterations to the plot, phase one of HS2 would need to open a year late.
The problem has come to be a whole lot worse because both files were composed.
Last month, a leaked correspondence suggested that HS2 may be around #30bn within its funding.
However, in December of last year, HS2’s chief executive, Mark Thurston, was still insisting everything was fine.
“We’re confident we have a good quote for the first phase,” he told BBC Panorama.
“We are not over budget.”
Second stage doubt
The Department for Transport memo also states there is a comparatively small likelihood that the stretch of the railroad, linking Birmingham to Crewe, which will be referred to as phase 2a, would be delivered punctually.
It places the probability of the occurring at a mere 35 percent.
In a statement to the BBC, HS2 Ltd said it had”provided periodic updates about the project”.
It said there was”extensive scrutiny” in the National Audit Office and Parliamentary Committees.
And it stated that chief executive Mark Thurston had”talked for some time about the cost pressures facing the job”.
His predecessor, Simon Kirby, said during his biography HS2 Ltd”functioned entirely transparently in regard to this Department for Transport that were kept fully appraised of all appropriate details regarding the cost and timetable of the job”.
The new Transport Secretary, Grant Shapps, is expected to provide Parliament with a complete update on the project weekly.
