REX Engineering Group is a multi-disciplinary consulting engineering firm with expertise in MEP and Structural Engineering.

REX evolved out of the 2018 merger between Innovative Engineering Group, a MEP engineering firm, based in Los Angeles, and Ntrive, a Structural Engineering firm with offices in Chicago and Detroit. Together, the organization leverages a combined history of more than three decades of delivering client-focused engineering solutions across a wide range of building types in both the public and the private sector.

The firm’s multidisciplinary, integrated approach, enables clients to rely on REX as a single source for a multitude of engineering services and project types. REX integrates aesthetic, high-performance renewable energy systems into the built environment. Collaborating with industry professionals, REX designs and assists clients to procure HVAC systems for commercial, new construction and retrofit applications. We offer building evaluation, system diagnostics, feasibility studies and lease consultation to help owners maximize their capital investments.

We view ourselves as a true partner, assisting our clients in all phases of a project from consulting and schematic-design to construction administration and post-occupancy survey.

Our clients rely on us for helping them solve the problems of tomorrow. As innovators, we’re readying ourselves for the future, by examining and improving our practices and envisioning the technologies, environmental concerns, costs, and regulatory constraints of the future.

We build our business around our talented employees. We want to see them succeed. In order for them to offer you to the best of their ability, we make sure our employee’s skills are what define their roles. We stand by the belief that creating a strong team is what makes a business work and makes your project a success.
