ARX USA

We bring deep expertise in geology and geotechnical engineering, with proven experience across diverse underground projects. Our team excels in site characterization, geotechnical data analysis, and predictive ground behavior modeling, supported by advanced 3D tools and simulations. Competences include TBM parameter optimization, ground support design, SEM, groundwater control, and risk management for mixed-face and high-pressure conditions, ensuring safe and resilient underground infrastructure.

Our structural engineering expertise spans complex permanent works and innovative temporary works. We have delivered challenging bridges, underground structures, and heavy civil components with a focus on safety, durability, and constructability. Our competencies include structural design in steel, concrete, and composite systems, seismic and dynamic analysis, and optimized temporary works such as shoring systems, cofferdams, and TBM support structures. We also have specialized experience in the design and delivery of signature and complex bridges, with particular expertise in cable-stayed structures.

We provide integrated design solutions for hydropower and pumped storage plants, combining civil, hydraulic, mechanical, and electrical expertise. Our capabilities cover waterways, caverns, pressure shafts, intakes, and powerhouse structures, as well as electro-mechanical integration. Specialized knowledge in transient hydraulic analyses -covering water hammer, surge control, and system stability- ensures safe and reliable operation of high-head and pumped storage schemes.

From concept to full LOD500 implementation, we deliver advanced digital modelling solutions that enhance coordination and constructability. With global project experience, our team develops 3D/4D/5D models, digital twins, and clash detection systems, using BIM as a powerful tool for logistics planning, sequencing, and schedule optimization, helping projects anticipate challenges and stay aligned with critical paths.

We offer complete construction management services for major infrastructure projects worldwide. Our Innovation & Global Academy approach combines international best practices with local adaptability, ensuring efficiency, safety, and quality. Competences include integrated engineering and logistics, sequencing optimization, risk management, and implementation of innovative methods that reduce time and cost without compromising safety standards.
