A consortium of Mace, Turner & Townsend and Atkins (MTA) has been appointed by the Ministry of Defence (MoD) as a Technical Service Provider on its Defence Estate Optimisation Portfolio framework.

With the appointment – recently confirmed at a signing ceremony with senior delegates – the three firms will operate as a single, coordinated team, supporting the Ministry of Defence (MoD) to develop, construct and integrate value for money solutions in the West of England and Wales region.


Defence Estate Optimisation (DEO) is the single biggest estates change programme within defence, bringing together an ambitious portfolio of interdependent programmes, construction activity, unit and personnel moves, and land release. It will invest £5.1bn in a better-structured, modern and more sustainable estate that improves security, resilience, and military capability.

The Mace-led team will provide design assurance and construction management services for this critical infrastructure portfolio as a sole supplier across the West of England and Wales region.

The trio, which already serves as delivery partner on the US Visiting Forces Infrastructure Programme at RAF Fairford in Gloucestershire and RAF Menwith Hill in North Yorkshire, will work to the Defence Infrastructure Organisation (DIO), the part of the MoD that will oversee the framework.
