A proposed highway bridge will be supported by 180 piles, each about 18 m long. The design load per pile is greater than 1000 kN. The soil conditions are neither unusually good, nor unusually bad, and you have limited experience with other pile foundations in the area. Based on this limited information, determine the number of pile load tests required for this project. State the main objectives of pile load tests.

Pricing Excavation and Backfill

Backfill, in construction, is the activity of returning the soil and gravel that are removed during building construction or using them again to toughen and support the foundation of the building or any other structural component.
