Innovative solutions through experience for the transport sector
RSK has worked on a wide range of infrastructure projects for over 30 years within the aviation, rail and highways sectors. We apply our end-to-end customised services to a broad range of project types at many different scales, including a wide variety of environmental surveys (archaeology, ecology, noise, geophysical) and ground investigations for road and rail schemes; detailed design and construction of highways; permanent way work for rail; and designing and installing renewable energy schemes for airports.
Our experience shows just how much we can do, providing environmental, social and technical services, innovative sustainable solutions and support to help future-proof projects. We ensure all contractor activities are robust by taking a sustainability-led and forward-thinking approach that ensures compliance and value for money.
With more than 30 years’ experience of supporting the development needs of the aviation industry, RSK has worked with airports to deliver solutions, from designing and installing solar farms at Edinburgh Airport to long-term carbon forecasting at Gatwick Airport. We provide a complete one-stop shop for delivery with fully integrated design solutions to complement the project life cycle.

RSK is a registered supplier with the UK’s Railway Industry Supplier Qualification Scheme (RISQS) and holds a principal contractor’s licence with Network Rail. We help clients to maintain and enhance the natural and built environment, including on several large rail infrastructure projects.
Learn moreAddressing global challenges
There are increasing expectations for the global population to have access to safe, reliable and sustainable infrastructure. This is an intrinsic part of the UN Sustainable Development Goals, formulated in 2015 to serve as a shared blueprint for peace and prosperity for people and the planet, now and into the future. The infrastructure sector plays a pivotal role in driving decarbonisation, with two-thirds of the UK’s total greenhouse gas emissions in 2019 originating from transport, energy, waste and wastewater infrastructure. By addressing these critical areas, RSK’s work directly contributes to solving global challenges, integrating decarbonisation strategies into projects that meet the demands of growing populations while supporting the transition to low-carbon economies.
The development of new, innovative and cost-effective methods of moving the population must now be set against these wider objectives of tackling climate change and ensuring that solutions are environmentally and economically acceptable and sustainable in the long term.
