Services
Post-Tensioning Systems
Our post-tensioning systems revolutionise concrete construction by enabling longer spans and complex geometries. This technology enhances structural performance while reducing material usage. With 70 years of innovation and 370 patents, we provide tailored solutions for bridges, high-rise buildings, and industrial facilities, ensuring optimal strength, durability, and cost-efficiency.
Asset Preservation
We extend infrastructure lifespan through comprehensive preservation services including inspections, repairs, and upgrades. Our specialists develop custom maintenance plans to ensure safety compliance and asset value retention. Using advanced monitoring technologies and patented repair methods, we address structural deterioration while maintaining operational continuity for critical infrastructure.
Bridge Construction
Specialist bridge construction services encompass design, post-tensioning systems, and heavy lifting operations. We deliver cable-stayed, segmental, and arch bridges for challenging environments, utilising proprietary technologies like the VSL system. Iconic projects include Incheon Bridge in South Korea and sections of the Hong Kong-Zhuhai-Macao bridge, demonstrating our capability in complex, large-scale infrastructure.
Ground Engineering
Our ground engineering expertise addresses foundation challenges through soil stabilisation, deep foundations, and retaining structures. We provide comprehensive geotechnical assessments and implement solutions like micropiles and ground anchors. These services ensure structural stability in demanding conditions, from urban environments to seismic zones, while minimising environmental impact.
Heavy Lifting
We execute complex heavy lifting operations for mega-structures using proprietary equipment and engineering expertise. Our capabilities include lifting steel superstructures for skyscrapers and installing massive bridge segments. The technology enabled the installation of Burj Khalifa's 828m pinnacle and Singapore's Marina Bay Sands Skypark, demonstrating precision in extreme-scale construction projects.
