Colin Buchanan & Partners Ltd, a leading transport planning, planning, urban design and economics consultancy, will merge with projects firm Sinclair Knight Merz (SKM).
Combining both teams creates a “world leading transport planning consultancy with global reach and increased capacity and capability to service clients both in the UK and overseas”, SKM said.
In the European and Chinese markets, the merged organisation will be known as SKM Colin Buchanan.
SKM chief executive and managing director Paul Dougas said: “Our strategy continues to be driven by the evolving needs of our clients and their operations.
“Right now, our transport infrastructure clients are facing particular challenges and require trusted partners to bring deep insights and innovative solutions that meet their commercial needs across the entire life cycle of a project.”
Colin Buchanan chairman Andreas Markides will take a key role in the new operation, joining the board of SKM Europe.
“SKM and Colin Buchanan already have experience through collaboration on a number of opportunities and we now look forward to providing that stronger, joint capability to all our clients,” he said.
