Surveying

SWI has been providing surveying services in northern Arizona for over 27 years. ALTA/ACSM Land Title, Right-of-Way, Boundary, Topographic, and Photogrammetric Control Surveys are just a few services we have provided for commercial, residential, utilities, sewer and storm drains, and water distribution system around the state. For a more detailed list of relevant projects, please visit our contact page to request more information.

Navajo Housing Authority – Five Scattered Residential Housing Developments

Between 2013-2014, SWI teamed with Cooper Aerial and Dyron-Murphy Architects to perform surveys on five separate NHA housing developments located in Shiprock, New Mexico, and Window Rock, Chinle, Dilcon, and Nazlini, Arizona ranging in size from 10 acres to 30 acres. Our suggested project approach to acquire digital imagery and AutoCAD data via aerial mapping proved to be a valuable asset in analyzing existing site conditions as well as a cost and time-saving measure. Supplemental topography, finish floor elevations, and subdivision boundary information were added for each site and final survey drawings were provided to the architect and engineering team for development of construction drawings and documents.

Rio de Flag Flood Control, Flagstaff

Our team worked alongside the City of Flagstaff and the U.S. Army Corp of Engineers, in providing survey services for a $54 million flood control improvement project in Flagstaff. Using both GPS and conventional surveying methods, our surveyors located Right-of-Way for the BNSF railroad, and existing City and ADOT roadways along the proposed three-mile corridor. For individual parcels affected by the proposed improvements, our surveyors prepared a comprehensive Right-of-Way and parcel map with legal descriptions and exhibits for property to be acquired by the City. SWI was able to seamlessly incorporate the USACE aerial mapping with the City’s coordinate system, together with supplemental LiDAR and aerial topographic data. Our team was also tasked with identifying utility conflicts throughout the proposed corridor for planning and construction documents.

Perrin Ranch Wind Farms, Williams

The Perrin Ranch Wind Farm is a 99.2 megawatt electrical generation project located just north of Williams and supplies power to the existing Arizona Public Service infrastructure. SWI was responsible for establishing horizontal and vertical survey control for the 22,000-acre site, establishing 48 miles of Turbine String Road Right-of-Way for construction access to the 62 turbine tower sites, and locating 60 miles of new easements for underground electric collection lines and 3.5 miles of 230 KV transmission line to the new APS Cedar Mountain switch yard. SWI produced record As-Built drawings for all site improvements upon project completion. Two survey crews and additional office survey staff worked full-time on this project for nearly six months.

Highway SR-179 Reconstruction, Sedona

The project consisted of the reconstruction of 3.3 miles of the Highway SR-179 corridor between Sedona and the Village of Oak Creek. SWI survey crews established Right-of-Way and easements for the road reconstruction and a new bridge over Oak Creek. Our team also provided construction staking for all phases of this project including slope staking; retaining walls; underground utilities; curb and gutter; and all storm drain structures. During construction, SWI monitored the contractor for compliance with design standards from the ADOT engineers and design specialists.

Porter Mountain Road, Navajo County

SWI conducted a survey of approximately 4.2 miles of Right-of-Way through four sections of public lands and several private parcels of land. Responsibilities included research of all adjacent private and public parcels for record documents, performing the initial survey of the existing Right-of-Way for Porter Mountain Road, and conducting the aerial topographic survey for design purposes. Our continuing responsibilities are to perform the survey of the new Right-of-Way, a Results of Survey Plat map, legal descriptions and exhibit drawings for all the new Right-of-Way locations.
