Morgan Sindall has been appointed to the Hub South West Scotland group’s £400m framework.
The contractor will join Ashleigh, Galliford Try, Graham Construction and Kier as a tier one supply chain member.
The framework has a potential pipeline valued at £400m to be delivered over the next five years, which could increase to £1bn over the next 10 years.
Hub South West Scotland made the appointment to strengthen its supplier network and enhance the value of its procurement and development process.
It said the ”recent supply chain refresh” has given the organisation an opportunity to expand to include large, medium and small local contractors that are “best placed to help us deliver our business”.
Hub South West chief executive Michael McBrearty said that Morgan Sindall brought a “pedigree in delivery experience”.
The contractor secured a place on National Grid’s £800m framework in July.
The engineer, procure and construct framework is for design, construction and commissioning of 11 kV-400 kV cable systems across National Grid’s network.
The agreement is set to last four years, with an option for a two-year extension.
