Featured Project

I-69 Highway Corridor

FLI-MAP was selected by TX DOT to obtain a Digital Terrain Model (DTM) of 42 miles of the proposed I-69 highway corridor in Texas. FLI-MAP’s dense data set allowed good ground data to be obtained through fairly dense vegetation, and the speed and efficiency of FLI-MAP allowed for savings of 9 months in time and approximately $1.5 million in costs over conventional methods.

Testimonials

"POWER Engineers has been on a steady diet of uprating projects and fast-track projects for more than six years. In that time, we have used LiDAR surveys for many miles of engineering. The technology is the best tool for cost-effectively achieving accuracy and satisfying a fast schedule. Having worked with several LiDAR providers, we have found the folks at John Chance to be the most capable of excellence in terms of technical knowledge, product quality, responsiveness and working relationship. These guys know what they are doing and always execute their work for us in the most professional manner. We routinely look to them first when we embark on a new project."

"We had the opportunity to work with John Chance and FLI MAP on a 150 mile 230kV transmission line upgrade project in 1998. We were very impressed with the planning, coordination, work ethic, professionalism, and quality of work the John Chance crews exhibited. When complete we were very satisfied with the work John Chance had performed for PNM and would be happy to recommend John Chance and FLI MAP to other utilities for their transmission line projects."

"Black & Veatch (B&V) performs services for transmission line studies, including economic evaluations, relating to the capacity of existing lines and determining the potential for transmission line upgrades. To obtain accurate and reliable information, we have worked with JCLS FLI-MAP data for more than four years and have found their data to be in an excellent format for analyzing transmission lines. JCLS can obtain the required data faster and more accurately than most attempts at conventional surveying from the ground. B&V uses this data to accurately model the existing transmission line in a true 'as-built' condition that provides very accurate structure locations, structure heights and conductor sags; all on a three-dimensional global basis. This data, which is complete for the entire line length, provides superior results when compared to an abbreviated survey that estimates ruling spans form limited information. The FLI-MAP data loads effortlessly into PLS-CADD and a three-dimensional model of the line can be developed for the analyses."


"After comparing several different survey methods for modeling the corridor terrain, we chose John Chance Land Surveys and their FLI-MAP system. By using the FLI-MAP system, Chance was the only firm that could meet the stringent schedule set by our client. As a result of the data collection speed and minimal amount of ground control needed, the overall cost was less than half of what we would have paid a ground survey crew to model by traditional cross-sectioning methods. Additionally, their unobtrusiveness of the data collection process was a real advantage due to environmentally sensitive corridor. When checked against cross-sections surveyed for quality assurance purposes, the data was well within acceptable tolerances for determining earthwork pay quantities, which was our principle use for the data. In summary, the FLI-MAP system allowed us to obtain accurate existing terrain data in a manner that was environmentally sensitive, conducive to our schedule and extremely cost effective. I would highly recommend Chance and their FLI-MAP system for any project of this type."
