Case Studies

Cornerstone provides a wide variety of Engineering and Design services to our clients in Industrial, Commercial, Institutional, and Governmental fields. You can read about some of our work for these clients below:


CEG completed an industrial ventilation project in our general area that started as a troubleshooting service and morphed into a complete system redesign. This redesign included a component-by-component evaluation of the ventilation system, evaluating the system for both HAP and solvent discharges. CEG worked with the client to validate the sizing of the existing pollution control device.


CEG is currently assisting a local property management firm in the refurbishing of older properties into more efficient and more aesthetically pleasing rental properties by renovating HVAC, electrical, and plumbing systems.


CEG recently completed a renovation of a water filtering facility. This renovation added a desiccant air drying system to the areas that contain the water piping. This work will improve the longevity of the piping materials, extend the painting intervals, and will decrease mold and mildew growth significantly.


CEG recently completed an HVAC renovation for a test facility in another state. The new system replaced systems installed in the late 1950s with more efficient HVAC systems with minimum interruption to the existing system.
