Air forces must be able to deploy rapidly across the globe, providing an ever-ready capability in a complex world. The infrastructure to maintain that capability requires careful planning and development through programmes that last many years, yet shifts in geopolitics and technology often happen on much shorter timescales. Getting air defence infrastructure programmes right is a balancing act — bringing stakeholders together, getting technical details right first time, and keeping on track with schedules and budgets while remaining adaptable. Services span strategic consultancy, programme delivery and supply chain management, and technical design and engineering support for air bases and supporting infrastructure.

Airport buildings and infrastructure are at the heart of an aviation sector that enables global connectivity and economic growth. Airport investors, users and wider stakeholders expect them to deliver on the 'brilliant basics' of safety, security, sustainability and operational efficiency. Passengers want the time they spend in airports to be enjoyable, relaxing and universally accessible. Governments and communities expect airports to deliver wider social and economic benefits, and society expects airports to play their part in decarbonising the aviation sector and minimising wider environmental impacts.

A global focus on nature is accelerating, with increased recognition that prosperous societies and economies depend on thriving and resilient ecosystems. Nature is fundamental to the success of projects, programmes and organisations — pragmatic, innovative solutions to enhance nature can help deliver projects with excellence and improve resilience to climate change, as well as contribute towards health and wellbeing and meet stakeholder and regulatory expectations. Services include nature-based solutions, natural capital assessment, ecology services, biodiversity net gain and environmental net gain — integrated with climate resilience, carbon reduction, social outcomes and digital innovation capabilities. Work spans global goals including the Nature Positive initiative and Taskforce on Nature Related Disclosures.

Climate change is a complex global challenge. The realities of climate risk, including physical impact and transition risk, affect every society and organisation. Limiting global warming to 1.5°C means navigating and delivering on international, domestic and market-based commitments to decarbonisation, alongside managing climate risk and ensuring economic and social infrastructure is adaptive and resilient. Global climate expertise is used to build decarbonisation and climate resilience into projects, investment plans, business strategies and delivery across three routes: decarbonisation strategy and delivery; climate risk and resilience; and climate policy and finance — unlocking economic and commercial, reputational and operational benefits for clients worldwide.

Dams and reservoirs have a vital role to play in improving water resource security, providing irrigation for food production, and developing hydropower schemes to increase supplies and storage of clean and reliable energy.

With more than 100 years of experience in dam and reservoir projects, expertise covers dam safety, flood risk assessment, rehabilitation, engineering and modelling, construction and operational support, and hydropower design and optimisation — addressing structural, mechanical, operational, seismic, climate and financial risks for new construction and remedial works.

Defence technology is evolving rapidly — from autonomous systems through to advanced materials and the integration of artificial intelligence into military vehicles. Armed forces need cutting-edge hardware to respond to existing and emerging threats, while staying the course and controlling costs on long-term delivery programmes. Expert advisory and technical capability spans strategic advice, project and programme management, and through-life management of equipment platforms including aircraft, land vehicles and naval vessels. Work is delivered for defence agencies alongside investors, contractors and manufacturers, designing and delivering equipment programmes that provide defence capability on land, at sea and in the air.

Delivering and maintaining the infrastructure and equipment for a modern nuclear defence deterrent is a huge responsibility, requiring highly skilled teams, facilities and capabilities. New projects often share sites with existing operational assets, making it critical to avoid or minimise disruption when innovative technical and logistical solutions are being developed. With over 30 years of sector experience and an even longer heritage in the civilian nuclear industry, multidisciplinary teams deliver integrated design, engineering and management solutions across the lifecycle of nuclear defence infrastructure — from strategic support and design through to project, programme and supply chain management.

Accessible, efficient and flexible transmission and distribution networks are critical to meeting the demand for electricity while achieving carbon and resilience targets. An unprecedented quantity of new infrastructure is needed as part of a global transition towards a decarbonised, enlarged and more flexible electricity system, with challenges around planning and consents, regulation and the routing of cables and interconnectors. Work with energy network operators, utilities, developers and original equipment manufacturers covers planning, design and delivery of transmission and distribution infrastructure projects worldwide — spanning strategy, regulation and development; design and engineering; project, programme and supply chain management; and commissioning and through-life management.

Meeting legal and regulatory requirements for environmental protection and improvement is essential. Making effective use of planning and permitting processes and exceeding standards for environmental management is an opportunity for leadership. Embedding and delivering positive environmental outcomes throughout the project lifecycle results in improved operational and commercial performance and more sustainable projects. Trusted environmental, planning and consenting advice is delivered across planning, masterplanning and engagement; impact assessment; environmental management systems; and environmental monitoring and reporting. Highly experienced environmental teams work on major infrastructure projects around the world, providing local knowledge and support while drawing on international industry leadership and best practice.

Health and care systems need to modernise to meet challenges arising from changing demographics and morbidity rates, an increasing focus on prevention, the rise of climate related illnesses and the spread of new and evolving infectious diseases. Achieving this while navigating rising patient expectations, tighter budgets, staff shortages and rapid advances in technology puts health care providers under significant pressure to deliver. A comprehensive and collaborative approach to delivering built assets across healthcare and life sciences designs them around the needs of people, with digital enablement at the core and with future adaptability embedded. Support spans reconfiguration, decarbonisation, digitalisation and optimisation of services and infrastructure.

Highway network operators face multiple competing priorities, including maintenance to keep roads safe for users and investment to enhance capacity and increase connectivity between communities.
