Located at the Langstone Business Park, the office will deliver sales, design, engineering and project management services, creating 12 jobs.
Cleveland Bridge has experienced an upturn in activity in the south of the UK and Wales, which has contributed to two consecutive profitable years with the company reporting profits for 2016 of £4m, an increase of more than £1.5m on the previous year.
Andrew Morris, head of infrastructure at Cleveland Bridge UK , said: “South Wales is strategically important for Cleveland Bridge, opening a large office here will enable us to strengthen our Welsh team and provide closer support to the Welsh infrastructure and construction sectors as well as regions such as the South East and South West of England.
“It will also allow us to take advantage of the wealth of skilled people from the area that will help Cleveland Bridge further grow its market share.”
