7. FUNCTIONS OF THE FOUNDATIONS
➢To provide stability to the bridge on the whole.
➢To provide a leveled base for the construction of pier and abutments.
➢To prevent the tilt and over turning of the pier and Abutments.
➢To prevent unequal settlement of subsoil.
➢The load transferring uniformly over the subsoil.
➢The foundation are carry the super structure load.

20. REQUIREMENTS OF A COFFERDAM
➢ It should be reasonably water-tight.
➢It should be easy to construction at the site of work.
➢It should provide least obstruction to the flow of
river water.
➢Its cost of construction and maintenance should be
low.

21. TYPES OF COFFERDAM
❖ Earth fill Cofferdam
❖ Rock fill Cofferdam
❖ Rock fill crib Cofferdam
❖ Single wall Cofferdam
❖ Double wall Cofferdam
❖ Cellular Cofferdam
