Our profession is a bridge between science and the humanities.

Engineering is human-centered innovation.

It’s the profession that brings together technical knowledge and human potential, employing innovation to solve our greatest challenges. We are strategists whose tactics respond to your vision when recommending the shape, bend, curve, equilibrium, and delivery of your project.

In an industry where consolidation is the norm, DeSimone stands apart from large engineering practices. The diversification of our specialized services is about supporting a global clientele experiencing complex challenges related to the interdependence of building systems. We remain independent so that you have bespoke solutions, wherever your vision and that of your partners and consultants takes you.

Structural engineering is where we began, and it is still the core of our practice. But through the years, we have expanded to provide other services, from façade and building envelope to vertical transportation to steel detailing and fabrication-ready modeling to advisory services.

To be truly effective, our profession needs to meet the non-technical and technical needs of building owners, developers, architects, contractors, and other partners. Clear communication, interdisciplinary coordination, and a resolute determination to realize design and programmatic vision are core principles of our practice.

We begin with a deep knowledge base, informed by a proven track record with advanced building systems. From our offices in the Americas, Europe, and the Middle East, we have contributed to the most striking, well-engineered, highest performing, and efficient structures in the world.

Our purpose is to be your trusted partner and provide reliable solutions to complex design and delivery challenges, though an excellent consultant experience.

We believe in innovation—not just for its own sake, but because the future demands new solutions to the challenges we face. Our buildings must rise to the challenge to be more sustainable, more efficient, more integrated, more flexible, and more resilient.

We move forward with your project knowing that field experience and expertise must be matched by a strong contextual understanding of the region, site, available materials, and fiscal restraints. Our engineers apply next-generation construction materials and invent long-span aerial marvels but do so with your unique requirements and ambitions in mind.
