Tetra Tech’s multidisciplinary experts supported the DIO on planning and design, procurement, and delivery of a masterplan to relocate UK troops across Salisbury Plain.
Under the Army Basing Programme (ABP), 4,300 UK troops and families are relocating from Germany to the Salisbury Plain area. For many, this means reuniting with loved ones not seen in a long time.
As Purchaser’s Representative and Technical Service Provider, Tetra Tech supported this transition, collaborating with the Defence Infrastructure Organisation and a wide net of stakeholders to deliver 917 homes in a challenging delivery environment, with minimal stakeholder impact.

Following the 2010 Strategic Defence & Security Review, the ABP aimed to return 20,000 UK troops from Germany by 2020. The Salisbury Plain Service Families Accommodation (SFA) represented a cornerstone of this ambitious plan, delivering homes to Larkhill, Ludgershall and Bulford alongside £1.2bn in infrastructure for working and living accommodation, workshops, offices, and welfare facilities.
Such massive scope meant a complex undertaking in masterplanning, heritage, environment and logistics that would span eight years of masterplanning, design, procurement and delivery. A major masterplanning exercise in itself had to be carried out to define the best locations for housing.
But tight planning application and funding deadlines accompanied a delivery environment that itself bore challenges almost as steep as the very slope on which the Larkhill development sat.
For one, the project sat next to Stonehenge, a world heritage site of great archaeological importance, which included World War I-era battlefield trenches that made waves in the news following their discovery by Tetra Tech archaeologists. Moreover, the project needed to address poor surrounding transport links and provide brownfield site and environmental impact mitigation.
Yet, despite the risks of missing objectives and dates, the project consistently delivered industry-leading outputs of 12–16 houses a week. How did we get there? This was the story of different organisations with unique drivers adopting joint ownership of problems for a better project outcome
To overcome this logistical Rubik’s cube, DIO and Tetra Tech implemented two-stage tendering for procurement and delivery while applying the principles of ISO 44001 Collaborative Working.
Collaborative working itself became the singular focus of a course-changing workshop in November 2017, convening all senior staff from the project team. Holding this workshop unlocked the door to openly sharing problems. It set the conditions for success whilst discussing corporate drivers, behaviours and perceptions. It pushed us towards a mutual understanding of our responsibilities in achieving project success.
It also inspired the establishment of a Joint Project Management Office at Ludgershall, where face-to-face discussions between senior staff resolved issues far quicker and encouraged joint ownership of issues, ultimately reducing risk and improving decision-making.
Frequent positive communication persisted throughout the project as we proactively engaged with stakeholders in the Army, DIO, County and Parish Councils, Lovell Partnerships, JCT Constructing Excellence, and over ten national bodies, agencies, and interest groups – from Environment Agency to Historic England.
Together with DIO planners and higher authority stakeholders – particularly Wiltshire Council – we developed a plan that received accolades from the Royal Town Planning Institute. This drew on our deep knowledge of strategic housing plans, town planning, ecology, archaeological and environmental risk factors, transport plans, local area development plans, and the Army’s drivers.
Efficient Delivery Realised
Thanks to the collaborative approach, and our high-quality technical reports, stakeholders initially opposed to development became plaudits of how we undertook the work, limiting eventual cost to the Ministry of Defence and ensuring smooth continuity of delivery. Indeed, all houses required for the summer 2020 moves were delivered on time, with the Army saving over £3.5m off the original liability.
The quality of the work we achieved together led to the Project Joint Relationship Management Plan, which now forms part of the ISO 44001-certified collaborative relationship between Tetra Tech and the DIO.
