Construction of the base for any large bridge takes time. The problems encountered during the construction of the foundation depend on the type of foundations, the soil strata found, the equipment / plant deployed and logistical problems. The planned construction difficulties during the execution will be kept in view when planning the works / period for the work. The foundation can be opened foundation, foundation of the pile, foundation of the well or any other type of foundation.

In the case of the foundation of the well, the different types of soils are found and it is difficult to give a clear timetable for sinking wells unless the details of the soil are very clear and the anticipated profile coincides with the real found. In the case of clayey and rocky soils, the sink rate is likely to be slow compared to the sandy soil. There may also be a requirement for pneumatic sinking subsequent to open grip due to difficulties in sinking the well.

As the cost of pneumatic collapse is very high, this should be judiciously deployed. In such cases, it is necessary to keep details of all sinking difficulties in a systematic order and this can be revised in consultation with the decision-making authority.
