CEI provides objective, expert civil and environmental engineering services to
clients in the US Northeast

There’s a reason we’re called “Comprehensive.” CEI is a client-oriented problem-solver. We take on projects that range from helping municipalities with compliance in the most cost-effective way possible, to serving as the objective mediator in complex post-project legal cases, to managing an entire state’s approach to water resource management. Our projects serve as the foundation for long-term relationships with our clients. In fact, we are still serving our first client from over 20 years ago.
