The contracts are the first of three that will be let for Scotland and North East structures and building renewals and enhancements, worth together £645m

Story Contracting picked up the £135m deal for renewals and enhancements work in Scotland, while AmcoGiffen has secured work on the London North East route valued at around £190m.

The remaining and most significant work-bank ‘Lot 1’, will be announced later this year and is valued at a further £320m.

As well as the renewals and enhancements framework, SNE will also name its two geotechnical framework partners shortly that will share £147m of work.

The awards are the first of Network Rail’s CP6 contracts to be let following the Office of Rail and Road’s final determination, which confirmed £35bn of funding for rail maintenance and renewals.

Scotland North East and Southern regions are anticipated to hold the largest work-banks for the coming five-years, with over £5bn of renewals spend estimated per region in addition to substantial network-wide upgrades.

Southern will be the next region to announce its contract awards next month.

John MacArthur, director of Story Scotland, said: “The award also supports our growth plans in Scotland and our vision to provide a highly professional turn-key service to the construction industry, where we deliver rail and civils infrastructure with our in-house labour resource.”

Andries Liebenberg, managing director AmcoGiffen, said: “We are delighted to have been appointed in partnership with Network Rail, delivering this programme of significant rail infrastructure investment. Providing substantial benefits to the travelling public, this framework award is testament to our long-standing relationship.”
