HS2 cost-cutting report released

HS2 promoter HS2 Ltd has released details of a cost-cutting study into phase one of the line between Birmingham and London.

The independently chaired cost-cutting study highlights 12 ways in which expenses can be reduced in the first phase of the rail network. It was conducted by Aecom engineering director Mark Raiss.

The study looked at ways of reducing the cost of specific elements, including the design of bridges, barriers, viaducts, tunnel portals, and retaining walls. It is the first of a number of studies, which are hoped to provide advice for future phases of the project.

Raiss concluded that collaboration between designers, contractors, and HS2 limited had been beneficial overall. He then outlined how the process could be streamlined on smaller aspects of construction.

He highlighted points such as bridge collum spacing, ensuring tunnel walls are watertight, foundation design, and derailment prevention, as ways of reducing expense. He said that smaller structures must be worked on before the costs are agreed in June this year.

HS2 leaders, including Transport Minister Nusrat Ghani, recently met with industry heads and local Government in the North and Midlands to promote the economic potential of high-speed rail links.

Ghani said: “We will continue to work closely with local authorities and businesses as we drive this ambitious project forward, to ensure that the East Midlands benefits from the full potential of HS2.”

Large derailment prevention barriers are under review, with Mark Raiss saying that cheaper alternatives are available. Construction is already underway on phase one, linking Birmingham and London, which is expected to be complete in 2026.

The report was commissioned by HS2 Ltd and began in November. Contractors have already been told to review plans and ensure that costs are reduced as much as possible.
