Environmental Permitting
and Documentation

We understand—and our clients have come to know—that keeping engineering design and environmental permitting under one roof creates the most effective approach to project delivery. This avoids the communication gaps that can occur when design engineers and permitting specialists work for separate companies.

In today’s complex regulatory environment, it is imperative that the design and permitting teams are integrated to develop the most buildable and permittable plans and specifications possible. Exeltech’s environmental scientists and engineers and work collaboratively to ensure designs meet current regulatory standards and environmental commitments and are highly constructible and cost-effective.
