Shephard-Wesnitzer, Inc. (SWI) was established in 1990 and is a leading engineering and surveying firm based in northern Arizona. We have offices in four Arizona communities; Sedona, Prescott, Cottonwood, and Flagstaff. At SWI we take pride in providing comprehensive Civil Engineering and Surveying Services to our local communities. SWI creates unique civil engineering solutions for site planning, grading, drainage and infrastructure development. We are experienced with the rugged terrain of northern Arizona, ensuring our designs will work with the natural topography to reduce unnecessary land disturbance and minimize construction cost. SWI’s success can be attributed to our ability to pair qualified technical expertise with local communities, restrictive budgets and varying terrain and environmental challenges. SWI’s municipal work has encompassed the entire infrastructure range from water, sewer and roadway projects to municipal building facilities, airports, and parks.
SWI offers a full range of Civil Engineering, Surveying, Structural Engineering, and Geographic Information Systems (GIS) services, along with in-house printing capabilities.
