Ashdod Port, located in the city of Ashdod on the western coast of Israel, is adjacent to the Mediterranean Sea and is the second-largest port in the country. This port expansion project includes the construction of a 360-meter shipping terminal, a 600-meter main breakwater, a 1,480-meter revetment, a 1,230-meter container terminal shoreline, a 770-meter operational dock, and 620,000 square meters of reclaimed land.
The foundation treatment scope covers a land area of approximately 1,300 meters along the container terminal shoreline and 600,000 square meters of reclaimed land, with a treatment volume of 6.6 million cubic meters.
The construction process utilized vibro-compaction techniques with a combination of filled and unfilled sand compaction. To meet design specifications, the relative density of backfilled sand was maintained at no less than 70%.
Our company carried out the local foundation treatment work, achieving a total treated volume of approximately 7.48 million cubic meters. The project ensured a robust foundation to support the port’s large-scale operations, including a 200,000-ton container terminal.
The Tibar Harbour Reclamation Area Vibration Gravel Pile Project is located 10 kilometers west of Dili, the capital of East Timor, and is the largest harbor development in the country. The project includes a 630-meter container high-pile wharf and dredging and reclamation works involving approximately 3.5 million cubic meters of material. The foundation treatment was carried out using bottom-feed vibro-stone column technology over 300,000 square meters onshore and 100,000 square meters offshore.
The soil in the area predominantly consists of coral sand, which has high calcium content and many voids, making it unsuitable for stability and settlement requirements. The vibro-stone column process was employed to strengthen the foundation and meet anti-liquefaction requirements, particularly for seismic resilience. Standard Penetration Test (SPT) results showed that 60%-70% of the area recorded less than 20 hits, with some locations exceeding 30 hits, fewer exceeding 50 hits, and a few reaching SPT 100.
The project involved the installation of 37,053 stone columns onshore and 17,543 offshore, totaling approximately 460,000 cubic meters. Two sets of bottom-feed vibroflotation equipment were used for onshore operations, while two specialized barges equipped with six bottom-feed vibroflotation units were deployed for offshore operations.
This project significantly enhanced the foundation stability of Tibar Harbour, ensuring long-term functionality and resilience for one of East Timor’s most critical infrastructure developments.
The Ras Az Zawr Port Project is located in the Sabkah region of the Arabian Gulf, on the Ras Az Zawr Peninsula in Saudi Arabia. This project is part of the infrastructure development for Ma’aden’s industrial city, designed to support the import and export demands of phosphate plants and associated industries. Owned by the Saudi Ports Authority (SEAPA) and managed by Worly Parsons (WP) as the consulting firm, the project site was initially in a desert state, featuring original sand dunes and the Sabkah Basin, with a land surface elevation ranging from +8.85 meters to +1.36 meters.
The construction area, formed by hydraulic filling, is divided into four zones: A (A1–A4), B (B1–B4), C, and D (D1, D2). Key activities include base slot excavation for the harbor basin, channel dredging, and gravity wharf construction. The seabed elevation ranges from -0.5 meters to -6.0 meters, with an average sea surface elevation of +0.93 meters.
The foundation treatment for this project employed vibroflotation and vibration compaction technology over an area of approximately 150,000 square meters, with a design depth of 15 meters and a spacing of 4 meters between compaction points. BJV130 vibrators were used for the compaction process. Post-treatment Cone Penetration Tests (CPTs) confirmed the compactness of the dredged sand layer, achieving a cone resistance of 7.50 MPa, meeting the design requirements. The compactness was consistent across all depth ranges, ensuring a stable and uniform foundation.
This project successfully reinforced the foundation to support critical industrial operations, contributing to the strategic development of the Ras Az Zawr industrial zone.
The Abu Dhabi Ayam to Gran Island Road Bridge Project is located 24 kilometers southwest of Abu Dhabi, UAE. The project features a total road and bridge length of 1,853 meters, including two bridges with spans of 80 meters and 120 meters. The roadway is constructed on a 40-meter-wide dam created through sand blowing and sea filling.
The project employed vibro-compaction technology for foundation treatment. The design specifications included a compaction depth of 7 meters and a triangular pile layout with a spacing of 3.5 meters. A 130 kW vibroflot was utilized to compact the sand effectively, ensuring foundation stability and meeting design requirements.
The total treated area for this project was 65,000 square meters, with our company successfully completing all construction works to provide a robust and reliable foundation for the road and bridge system.
