Company profile

Flint & Neill is a firm of consulting engineers, providing innovative and advanced solutions to a variety of civil and structural engineering challenges worldwide. As part of COWI Group’s international Bridge, Tunnel and Marine Structures division, we have access to considerable engineering, environmental and planning resources throughout the COWI network, such as Donaldson Associates Ltd (also part of BTM division), meaning we can now tackle tunnels, offshore wind farms and other works in addition to our long standing portfolio of bridges and structures.


Flint & Neill engineers are able to adapt to the evolving needs of clients and retain our world leading position as specialist civil and structural engineers. Our engineers are equally at home in assessing existing structures and performing expert investigations as in designing new structures. We have always been committed to solving problems through a sound understanding of structural behaviour, never afraid to move outside the scope of codes and standards to apply engineering first principles where necessary. This approach has regularly enabled us to tackle new problems of significant complexity and has led to our involvement with the development and drafting of codes of practice for a variety of engineering applications.
