The firm will carry out the complex task of improving facilities in Birmingham while the building continues to open its doors as a major entertainment venue.
The biggest change at the 20-year-old venue, part of The NEC Group, will see a glazed frontage overlooking the neighbouring canals, three towering sky needles and steps down to the waterway.
NEC Group Arenas managing director Phil Mead said: “The aim of the redevelopment programme is to make the NIA more accessible, both visually and physically, taking advantage of its key canal-side location.”
The plan to extensively upgrade facilities with new public concourse levels to increase the food and drink facilities available pre, during and post show. The works will also enhance the area around the arena.
Considerable M&E enabling works will be required throughout the various phasing to ensure that existing services are maintained and integrated with new.
The building arm has also be selected by developer Grainger to build a mixed-use project at Macaulay Road in central London worth £23m over a mix of eleven buildings.
Galliford Try chief executive Greg Fitzgerald said: “We are delighted to have won two such significant contracts in an extremely competitive market. These contract awards show that we can compete in all regions and provide our clients with high quality cost effective solutions for their needs.”
