The HS2 Phase One Main Civil Contracts were signed in July 2017 and Phase One design development and enabling works are continuing to progress. Notice to Proceed is the formal contractual process which enables each Phase One supplier to move from design and development to construction.
HS2 Ltd has advised the Government that it intends for Notice to Proceed to take place later in 2019 to allow it to finalise costs and plans with its contracted suppliers. Full construction of bridges and tunnels will commence following award of Notice to Proceed. Essential works to prepare the route for this stage are well underway, with over 60 active sites, including major works at Euston, Old Oak Common, Curzon Street and Washwood Heath.
Expenditure on HS2 to date is set out in the Annual Report and Accounts of HS2 Ltd and the Department for Transport. The Government has committed to update Parliament on HS2’s progress at least once a year.
The Phase One Full Business Case, planned for publication later in 2019, will include an updated estimate of cost and schedule and an accompanying assessment of benefits.
