A tremie is a watertight pipe, usually of about 250 mm inside diameter (150 to 300 mm), with a conical hopper at its upper end above the water level. It may have a loose plug or a valve at the bottom end. A tremie is used to pour concrete underwater in a way that avoids washout of cement from the mix due to turbulent water contact with the concrete while it is …

In the case of end bearing piles, the space between the piles that are placed adjacent must not be less than least width of the pile. The spacing of piles as per the practice followed in the UK are based on the following formulae: End bearing piles: Spacing S = 2.5d + 0.02L. Cohesion Piles: Spacing S = 3.5d + 0.02L

The concrete mix for the piles was a 60 MPa mix based on a triple blend with 25% fly ash, 7% silica fume, and a water to cement ratio of 0.32. The concrete was also designed as a fully self consolidating concrete, incorporating a viscosity modifying admixture with a slump flow of 675 +/- 75mm to limit the possibility of defects during construction.
