These types of facilities make America what it is today. Industrial and manufacturing are the root of the American economy and its history. These companies create millions of jobs around the country and produce all types of products consumers use. The mechanical systems in these buildings are important in the case of clean rooms and paint rooms, so air quality and air pressure are both important. From aviation to oil and gas facilities, the team at Dean E. Norris, Inc. has completed these types of projects since its inception in 1971.
