Former Skanska High Speed 1 boss David Blackburn is the new managing director for the Galliford Try / Hochtief / Dragados High Speed 2 joint venture.
Mr Blackburn will lead Momentum Infrastructure’s bid for the £11.8bn civils packages and £900m enabling works.
The JV has been shortlisted for four of the seven civils packages, including the £1.3bn Chiltern Tunnels section to Brackley.
It has also been shortlisted for one of the three enabling works packages, which includes the northern section of the line between London and Birmingham.
Mr Blackburn recently joined Galliford Try as its major projects director from Australian firm Leighton, where he led the $3bn (£1.74bn) Sydney Metro NW OTS project.
He had previously spent more than 30 years with Skanska, which included leading the £1bn M25 DBFO widening works and a number of the major contracts on HS1.
The news comes as HS2 revealed the shortlist for £520m of consultants packages for phase two of the line.
Four teams were shortlisted for the £350m professional services contracts, while three were shortlisted for the £170m development partner role.
Momentum Infrastructure main board director Sally Cox said: “David comes with a great pedigree and he will be an excellent addition to an already strong team.
“He is highly respected within the professional community and brings great knowledge and experience of our industry, the needs of our clients and in the delivery of strong results.”
