Global Structural Engineering Innovation
Founded in 2004 by Brian Eckersley and James OCallaghan, our firm has grown into a global team of 160 structural and facade engineers operating across 10 international offices. We specialize in integrating engineering rigor with architectural vision to deliver technically sophisticated solutions for complex building projects. Our expertise spans structural engineering, facade engineering, and digital design, with a particular focus on innovative material applications such as glass, carbon fiber, and mass timber. We maintain a strong commitment to sustainability, incorporating low-carbon design principles and environmental performance analysis throughout the project lifecycle. Our portfolio includes landmark projects like the world's tallest hybrid timber tower and precision-engineered structures that balance heritage preservation with modern functionality.With over two decades of experience, we combine analytical precision with creative problem-solving to address both traditional and unconventional engineering challenges. Our digital design capabilities enable advanced computational modeling and optimization, supporting our mission to push the boundaries of what is structurally possible while maintaining practical constructability. We collaborate directly with end-user clients, architects, and contractors to provide tailored engineering input at every project stage, from conceptual design through construction completion.

Services
Structural Engineering
Our structural engineers develop optimized solutions for new and existing buildings using advanced analysis techniques. We specialize in complex geometries and non-traditional materials while maintaining strict compliance with international building codes. Our approach balances technical precision with architectural vision to create structurally efficient, economically viable solutions for projects ranging from private residences to supertall towers.
Facade Engineering
We design high-performance building facades that integrate aesthetic vision with technical functionality. Our expertise includes advanced glazing systems, climate-responsive envelopes, and heritage-sensitive restoration. Through computational modeling and material innovation, we create facades that optimize energy efficiency while achieving architectural intent across diverse climatic conditions and regulatory environments.
Digital Design
Our digital design team develops algorithmic tools to enhance engineering decision-making and project delivery. We employ parametric modeling, environmental simulation, and data-driven optimization to improve design accuracy and sustainability outcomes. This approach enables real-time performance feedback and supports complex geometry resolution for technically challenging projects requiring high precision.
Sustainability Consulting
We integrate carbon footprint analysis and life-cycle assessment into all project phases. Our sustainability consultants develop passive design strategies, material optimization protocols, and retrofit solutions that reduce environmental impact. Through proprietary tools like EOC ECO2, we quantify design decisions' environmental effects to achieve measurable carbon reduction targets while maintaining structural integrity.
Heritage Engineering
Our specialists preserve architectural heritage through technically sound restoration methodologies. We combine traditional construction knowledge with modern engineering techniques to reinforce historic buildings while maintaining original character. This includes seismic upgrades, material conservation, and adaptive reuse strategies that extend building lifespans while meeting contemporary performance standards.
