Speculation grows that rail project will have to go overseas to replace chief executive Simon Kirby

Speculation is growing that HS2 Ltd will have to go overseas to replace chief executive Simon Kirby who is leaving in December after two years in the post.

Kirby shocked the industry last month when it was announced he was joining Rolls-Royce as the engineer鈥檚 chief operating officer. He had joined HS2 Ltd from Network Rail back in May 2014.

HS2 Ltd says an appointment is expected early in the new year, meaning it is likely that its chair Sir David Higgins will be asked to fill Kirby鈥檚 role on a temporary basis.

Names being bandied about to take up the post include Crossrail chief executive Andrew Wolstenholme, Thames Tideway boss Andy Mitchell and former Laing O鈥橰ourke chief operating officer Tony Douglas. The favoured internal candidate is rumoured to be commercial director Beth West, a former investment banker.

But Patricia Moore, managing director of infrastructure at consultant T&T, said: 鈥淭he problem is I don鈥檛 think there鈥檚 an obvious candidate who鈥檚 available.鈥 And Richard Threlfall, head of infrastructure at KPMG, said: 鈥淚 won鈥檛 be surprised if the search doesn鈥檛 end up having to go more global for the right person.鈥

The speculation comes after prime minister Theresa May and her chancellor Philip Hammond gave the scheme their backing at last week鈥檚 Conservative Party conference. An HS2 spokesperson confirmed to 黑洞社区 that the scheme plans to keep to all of its published project milestones in the months ahead.

Upcoming decisions include the imminent selection of three contractors for 拢1bn phase 1 enabling works in the next month - the first big construction contracts - and then picking contractors for the 拢9bn main civil engineering works in the first half of 2017.

鈥淓nabling works contracts, royal assent and major works contracts all remain on track for construction to begin next year,鈥 the spokesperson said.

In addition, he confirmed that selecting providers for 拢500m of professional services work on phase 2 would happen once the expected phase 2 route is announced later this autumn.

Paul Dyson, head of advisory at consultant Hill International, says: 鈥淚t鈥檚 significant because once you鈥檝e let these contracts HS2 opens itself up to costs if it backs out.鈥

HS2 will choose between Bechtel, CH2M Hill and a Mace/T&T JV as development partner for phase 2 by the end of the year. Design consultants will also be chosen, with an Aecom/Capita JV, Arup, a Mott MacDonald/WSP JV and an Atkins/Arcadis JV all in the running.
