The below map depicts of the common 100 mile radius area of regional work we serve on a regular basis. IES does perform work outside of this region. Should your project require our services outside of the regional work area, we would be glad to assist with your project upon request.


We can  cater to your needs as we are a licensed professional engineering firm within Delaware, Maryland, New Jersey, and Pennsylvania.  We also have associates that are licensed to the rest of the Contiguous United States.
