The Port of Alexandria in Egypt handles about 60% of the country’s exports and imports. It consists of two harbors separated by a peninsula which is T-shaped. The shallow east harbor is not navigable by large vessels, but the west harbor is used for commercial shipping. A plan has been elaborated to expand Alexandria Port to handle more cargo, and the new ‘multi-purpose terminal 55/62’ occupying an area of approximately 56 ha will be reclaimed and improved.
Bauer Egypt was awarded by the main contractors EDECS and GIECO the deep foundation works of a semi-rectangular quay wall with a volume of 225,897 m3, consisting of a front diaphragm wall, two rows of middle piles and a rear row of barrettes. The front diaphragm wall will be 1.2 m thick over a length of 1,500 m and 1.0 m thick over a length of 1,025 m. The 1,326 middle piles and the 660 rear barrettes will have a depth of 39 m, just like the front diaphragm wall.
In addition to four trench cutters, two Bauer drilling rigs of the type BG 28 are in use. The vertical elements are planned to be executed parallelly by the means of two mega mixing plants located initially on the north and south sides of the wall covering a 200 m radius around each of them. The mixing plants will be shifted along the quay wall as the work progresses. Construction work executed by Bauer Egypt began on September 28, 2020 and is expected to take a total of ten months.
