Box culvert is a rectangular shape reinforced concrete structure consists of single or multiple boxes allowing movement of water and traffic. The American Concrete Pipe Associations precast concrete box section program was implemented to develop a product for these applications and. Box Culvert - A culvert in the shape of an enclosed rectangle and consisting of a bottom slab two wall elements and a top slab.

Buried structures with horizontal dimensions less than 10-0 are not classified as bridges. Culverts diameter or height greater than 1200. Flexible Pipe - a structure that transmits the load on the pipe to the soil at the sides of the pipe.

Designer - Individuals designated by the Structural Engineer to use this manual to design and detail culverts. Design the culvert to fit Design the channel and floodplain. State as an example the coordination of construction and design.

A cast in- situ headwall extension with minimum thickness as specif ied in the standard drawing 1243 Drawing 2 and 3 shall be used to connect the precast headwall and the pipe or box culvert. BBS will provide assistance on design of new culverts not meeting Design Table requirements and in need of special design. Circular pipe culverts are widely used in transportation applications to transport stormwater under roadways railways etc.
