ESI provides surveying and mapping expertise for transportation, signal and highway projects. Services include base mapping, staking of centerline and right of way lines, determination of right of way, and preparation of right of way instruments and plans.

ESI personnel have excellent training and experience and are equipped with state of the art equipment including digital levels, total stations, electronic data collectors, Robotic, reflectorless total station and Global Positioning System (GPS) using Trimble R-8 GPS with Glonas capability. GPS experience includes both static and RTK as well as use of the statewide VRS network. ESI personnel not only have the day to day experience with GPS, they have also received additional training in the use of this technology. Survey data is collected using feature codes which provides accurate transfer to MicroStation files. Projects are prepared electronically through the use of CAD using InRoads and MicroStation.

ESI has had years of experience in all types of surveys. This includes construction surveys, boundary surveys, ALTA surveys, subdivision design and layout, topographic surveys, horizontal and vertical control networks, cross-sections, staking of alignments and right of way lines, and mapping of utility locations. We have also researched and located section corners and re-established section corners.

UDOT projects for which ESI set the aerial targets and provided the project survey control include 35 miles along the Western Transportation Corridor in Salt Lake County and 38 miles along the I-15 corridor from Santaquin north to the Salt Lake County line. These control surveys were performed using GPS static and RTK methods with ties to HARN control points. We also surveyed 28 miles along SR-12 from Escalante to Boulder. Since there were no HARN control points available in the area, accurate control was established using six hour observations and using the National Geodetic Survey's OPUS program to determine accurate control.

To insure the accuracy of the survey data, ESI has a QC/QA plan for the surveys. This includes detailed checking and review of the raw data collected by the field crews. The field survey techniques and drawings produced from the survey data is reviewed by a professional land surveyor.

ESI's years of providing survey and mapping has given us the experience to know how to identify and minimize potential delays. Our staff of five licensed professional land surveyors assures that surveys are conducted in a professional and accurate manner. By maintaining early and frequent coordination, cooperation, and communication, many potential problems and delays can be avoided as the process proceeds.
