The majority of our surveying work has been for the Systems Engineering Department of Southwestern Public Service Company and encompasses thousands of miles of Right of Way, Preliminary, and Construction layout surveys for power transmission lines. Other endeavors have included ground control for aerial photogrammetry at Tolk Station, a coal fired generation facility; boundary and highly detailed topographic mapping of six (6) power generation plant sites in west Texas and two (2) plant sites in southeastern New Mexico, (100 acres to 5000 acres each); a survey of approximately 150 sections of land for water rights acquisition and/or transfer; a survey for five (5) miles of railroad to Tolk Station; and multiple boundary, topographic, and construction layout surveys for substation and interchange sites with access roads in Texas, New Mexico and Oklahoma. Also represented are design and construction surveys for major highways in New Mexico. Most recently completed in 2003 is a 354 mile power transmission line traversing 11 counties, four states, and five State Plane Coordinate system zones. We developed a horizontal and vertical control network with 13 working zones based on the State Plane System which produced a single contiguous project specific Coordinate system for design, land ties, and boundary and easement calculations in Texas, Oklahoma, Kansas, and Colorado. This system maintained coordinate positional error to less than 0.15 feet in all locations across the entire 354 mile project. This 3.3 million dollar survey project spanned over a time period of approximately four (4) years, approximately $800,000/ year in addition to other ongoing work.

Recent construction staking projects include Zia Park Racetrack and Casino, Lea County Detention Facility, Nor-Lea Hospital, Seven Rivers Substation Expansion, Potter County Interchange, Amerada Hess Substation Expansion and Eddy County to Seven Rivers 230 kV Transmission Line.

In addition, Pettigrew & Associates, P.A. was asked to complete an ALTA survey of the Caprock Wind Ranch in Quay County, New Mexico. The ALTA survey involved a project area of 31 sections across 4 townships. The ALTA also encompassed the transmission line route that covered an additional 12 miles of right-of-way. Through the course of our work we retraced over 65 sections in order to complete the ALTA survey. Through the course of our ALTA survey we were in direct contact with landowners gaining access and research for our work. The project also included construction surveying of the Substation sites and the transmission line. Other projects include boundary analysis and determination, stream and corridor cross sections, gradient boundary determination, preliminary surveys for design, route selection and right of way, construction layout, as-built surveys,
and control for aerial photogrammetry and Lidar surveys, in the states of Texas, New Mexico, Oklahoma, Kansas, and Colorado.
