METHOD STATEMENT INSTALLATION OF SHEET PILES

Ohayo gozaimasu

The installation of sheet piles are the famous type of temporary works for the construction of  building or bridge during foundation works such as pilecap structural.   Steel sheet piles are long structural sections with a vertical interlocking system that creates a continuous wall.

The walls are most often used to retain either soil or water. The ability of a sheet pile section to perform is dependent upon its geometry and the soils it is driven into. The pile transfers pressure from the high side of the wall to the soil in front of the wall.

There are permanent and temporary applications. Permanent sheet piles remain in the ground and serve as permanent retaining structures. Temporary sheet piles are designed to provide safe access for construction, and are then removed.

However in the construction works today with amount of contract sum too  low due to the tight competition during tender process and in order to secure profit margin sometime we overseen and under estimate the ground condition without take considered the temporary cost such as sheet piles.

If the  contract awarded  based on the bill of quantities it so lucky if the client could agree on the variation order for the additional works. Sometimes it so hard to fight because in the normal contract document all the temporary work such as providing access and etc within period of construction have included under general works and preliminaries item.
