Bridges

Part 6 covers the range of site activity likely to be met in constructing small to medium road and pedestrian bridges up to 40 m in maximum span. To ensure that bridges are properly constructed in accordance with the design drawings and specifications, engineers need to be well-informed on all aspects of the design and construction, including awareness of the problems that may arise and the levels of the various risks associated with their realisation. They need to know the important quality, safety, environmental and other issues relating to each activity before the activity is actually undertaken. They need to be able to identify when problems are emerging. The design objectives of serviceability, strength and durability do not lapse with the completion of a set of bridge drawings but are carried through into the specifications and the construction work itself.
