Survey

Premier provided field surveying for the final design of the I-17 Traffic Interchanges at Pinnacle Peak and Happy Valley Road.   Our survey department was responsible for locating and tie-in to existing ADOT control monuments and verifying control points used.  We provided detailed topographic field surveys of the interchange tin-ins to the arterial roads as well as frontage road tie-ins and processed field data and compared the field check shots to the existing ADOT DTM. We also prepared supplemental topographic base drawing to be incorporated into the existing ADOT survey base drawings, which depicted all features from the supplemental field survey including spot elevations, culvert and sanitary inverts (including pipe sizes), additional surface utility structures, edges of pavement, curbs, walls and other physical features.
