Many construction companies think that they can build bridges. It is not a good idea to let them discover their mistake at your expense. This is a specialist activity with almost every aspect controlled by British Standard, DoT Bridge Directives and bridge design criteria. It should also be clearly understood that Insurance Policies written for general construction usually exclude working on bridges.
It is our policy to carry out all operations with our own employees. We suggest you look twice at firms who do not want to provide foundations or who use sub-contractors for this crucial operation. We feel our in-house approach is the only way to ensure quality and site safety.

If the depth of the load bearing beams under the deck becomes a problem this can be reduced by using a truss. The stiffness is supplied by the handrails and this allows significant reductions in the thickness of the deck. Trusses also have an attractive appearance and can add to the appeal of a bridge.
