ISG has been appointed to build and upgrade three data centres, including its third new-build Nordic project worth around £120m.
The company did not identify its global technology customer. ISG’s first project was handed over in February 2014 and the second will be completed over the summer.
The firm has also secured a £20m upgrade of two existing data centres for a global banking and financial services organisation in the UK.
ISG chief executive officer David Lawther (pictured) said: “We are delighted to continue to be a key data centre delivery partner, as we grow both in scale and resource to service this highly specialised sector.”
