1200 tons of both U and Z type sheet piles are used. Shipping port is Karachi. During the construction, the sheet piles were braced against the existing pier. To guarantee the impermeability of the cofferdam, the sheet pile interlocks were filled with an inexpensive hydrocarbon product that was easy to handle. The Steel Sheet Piles were installed with a vibrohammer ICE 223, which had an additional weight of 2 tonnes, to permit easier penetration in the sandy harbour ground. Once the foundation was complete, the space between the sheet piles was in filled. The sheet piles were then tied back to the pier and the struts were removed.
