CNA Consulting Engineers is an award-winning professional civil and mining engineering firm that provides services for projects built in, on, or using soil and rock materials. We have a 30-year track record of successful projects and satisfied clients on local, national and international projects. We routinely assist clients with all phases of the project life cycle – from conceptualization through maintenance and rehabilitation. Projects include work on underground transportation facilities and occupied underground spaces, utility tunnels, infrastructure evaluation, geostructural research and evaluation, and much more. Our firm also specializes in the design of inhabited underground space and frequently take the same role for underground projects that architects do for above-ground projects – the role of project leader and coordinator. We often team with other firms to provide mechanical, electrical, fire protection, fire and life safety, outfitting and similar design services.
