We realize the importance of environmental responsibility in our professional and our personal lives. Our vision of environmental responsibility and the practice of Sustainable Design are based upon a definition of sustainable design criteria. As sustainability encompasses a very large realm of responsibility, we limit its scope to sustainable design criteria within our field of expertise. Therefore, we have adopted the following criteria for sustainable design:

“Sustainable design criteria minimizes Environmental Impact throughout the conception, creation, utilization, and ultimate demolition of a structure or system while providing a healthy, comfortable and productive environment for people.”

Strict adherence to the values expressed in this definition allows us to provide quality engineering services to our clients based upon sound engineering principles, environmental responsibility, effective economic decision making, and educated compromises.
