The GCE (Highway) Interchange Section in Malaysia is located on the outskirts of Salam, the capital of Selangor, serving as a key transportation hub that connects the city to its surrounding areas. The project was undertaken to reinforce the road foundation, utilizing vibro-impact gravel pile technology with a pile diameter of 0.8 meters.
Our company was responsible for the construction, completing a total of 40,855.4 meters of vibro-gravel piles within a construction period of 5 months. This project enhanced the stability and durability of the interchange foundation, supporting the region’s vital transportation infrastructure.

The Macau Landfill Area is located south of the South Link Bridge of Macau International Airport and north of the Macau Power Plant, facing the artificial island of Macau International Airport across the sea. Sea mud accumulation in the area has disrupted navigation in the drainage channels near the Luhuan power plant and the airport rescue channel. To resolve this issue, the Macao Environmental Protection Bureau re-planned the landfill area to accommodate both sea mud storage and navigable waterways.
Under the jurisdiction of the Macao Environmental Protection Bureau, with Zhenhua Bay Engineering Co., Ltd. as the general contractor, the project involved treating soft foundations, including cofferdams and silt below the dock. Offshore bottom discharge and vibration compaction gravel pile technology were utilized to stabilize the foundation.
Our company was responsible for the construction, deploying one pile-driving ship equipped with four sets of offshore bottom discharge and vibration compaction equipment. The project achieved a cumulative completion of nearly 200,000 meters of work, with the construction period spanning from October 2020 to January 2021.

The Fourth Bridge on the Panama Canal is a planned road-rail cable-stayed bridge located west of Panama City, crossing the Panama Canal north of the Bridge of the Americas. The bridge connects the northern corridor and Albrook Metro Station on the east to the Aleihan Road on the west, aiming to alleviate traffic congestion and improve connectivity for the Panama Pacific Project and the canal’s western side.
The main bridge is a 965-meter-long highway cable-stayed structure, featuring a 485-meter main span, a 190-meter H-shaped tower, and a composite beam main deck. The bridge has a width of 36.87 meters and a navigation clearance of 75 meters.
Our company undertook the construction of vibro-crushed stone piles for the West Interchange section of the project, completing a total contract volume of 140,000 meters, ensuring the stability and durability of the bridge foundation.

The Girongo Water Supply Project, located in Luanda, the capital of Angola, was developed by the municipal corporation of PowerChina. The project involves the construction of a water treatment plant with a capacity of 500,000 tons per day, serving both production and domestic needs, primarily in the eastern part of Luanda. The plant spans a service area of 60,800 hectares and, upon completion, will become the largest water treatment facility in Angola.
This project is a critical infrastructure initiative aimed at increasing the water supply capacity of the capital region. Once operational, it will address the drinking water needs of approximately 10 million residents in Luanda, significantly benefiting the population.
The foundation treatment scope includes key structures such as Q1 (water intake), water intake canal, front pool, water intake pump house, generator set, and transformer station. The work covers a total reinforcement area of 6,176 square meters, utilizing approximately 1,783 vibration-driven gravel piles and a project volume of about 35,000 meters.
This project marks a vital step toward enhancing Angola’s water supply infrastructure, contributing to improved quality of life for millions in the region.
