Station can now be built in a single phase rather than two bringing fresh budget savings

HS2 downsizes Euston station to save costs

The station will now move to a simpler 10 platform design from the originally planned 11 platforms.

This will allow the station main contractor joint venture Mace Dragados to build the £2.6bn project in a single stage, rather than two stages as originally envisaged.

The changes are far less dramatic than some in the industry feared after a 15-month review looking for cost-saving options and efficiency opportunities, depending on the scope of the northern leg of HS2.

HS2 minister Andrew Stephenson revealed the new plan in a six-month update to Parliament yesterday.

He said that the changes will ease the £400m budget pressure already identified on Euston station budget.

Stephenson said the exact savings would be identified as the updated design is developed over the coming months.

“In response to a recommendation from the Oakervee Review about looking into the efficiency of the Euston station, the move to a smaller, simpler 10-platform station design at Euston has now been confirmed,” he said in the report

“This will provide a more efficient design and delivery strategy and play a significant role in mitigating the affordability pressures recently identified.

“Moving to this revised HS2 Euston station design maintains the station infrastructure capacity to run 17 trains per hour, as set out in the Phase One full business case.”

Stephenson also highlighted potential minor delays in the southern section of the line leading into Old Oak Common from outer London.

He said contractors were now focused on identifying efficiencies and controlling risk in these key areas.

The added delivery risk stems from residual delays in completing enabling works and handover to main works in certain locations.

Slower than planned design progress and securing planning consents by the main works civils contractors had also limited productivity of the supply chain.
