Bridge construction set out

Bridge construction set-out can vary from a small pedestrian bridge to railway bridges and dual lane carriage ways. Generally these structures are constructed out of precast concrete segments, steel girders or pre-cast super tees. Sometimes a structure may incorporate a combination of all of these methods.

All of these type of structures require detailed survey work to be carried out to ensure that the design criteria and structural integrity of the bridge is met. A good knowledge and understanding of what survey information is required for structures of this type is essential. The information provided by the bridge surveyor can play an important part in the construction process, ensuring that engineers and the construction team are aware of how progress is advancing and if the design criteria is being met or amendments need to be made.
