PHILADELPHIA, PA, Sep 9, 2026 – Bentley Systems has opened a Center City office that brings its engineering and geospatial software teams together as it integrates Cesium’s 3D geospatial engine with the iTwin Platform for infrastructure digital twins. The Curtis Center site also includes an experience center where developers, infrastructure professionals, students and partners can explore software used for infrastructure design, delivery and operations.
Bentley acquired Cesium in September 2024. Cesium’s developer community are based in Philadelphia, while the new office will support software development and demonstrations of Bentley’s infrastructure tools. Bentley began operating in the region at the University City Science Center and maintains its corporate headquarters in Exton. Its regional collaborators include the University of Pennsylvania, Drexel University and engineering firm Pennoni.
“Bentley’s downtown expansion is a strong vote of confidence in Philadelphia’s talent and technology ecosystem,” said Mayor Cherelle L. Parker. “This investment will expand economic opportunity, strengthen ties with our universities and developer community, and reinforce Philadelphia’s role as a global center for innovation.”
“Philadelphia has always been a city where innovation, talent, and opportunity come together,” said Pennsylvania House Appropriations Committee Majority Chair Jordan A. Harris. “Bentley’s continued investment in our city signals an enduring commitment to Philadelphia and creates an opportunity to create pathways for the next generation of students, developers, and infrastructure professionals. This new tech hub will bring people together, turn innovation into real-world solutions and help ensure that the careers and technologies shaping our future are being built right here in Philadelphia.”
Nicholas Cumins, CEO, Bentley Systems, said, “Bentley’s acquisition of Cesium was based on a shared vision of an open, interconnected 3D world. Today, opening our new Philadelphia office is the physical manifestation of that vision. By bringing our teams together in this vibrant tech hub, we are accelerating the integration of engineering and geospatial data to help our users design, build, and operate safer and more resilient infrastructure.”
Patrick Cozzi, chief platform officer, Bentley Systems, said, “The Philadelphia region is where Cesium started as an ambitious idea to bring 3D graphics to the web. Opening this office in Center City feels like a homecoming, but with global scale. This space will be a lighthouse for the open-source community, a collaborative engine for developers, and a testament to what happens when you combine the best of infrastructure engineering with the power of real-world 3D data.”
