Location and acquisition of utility and highway rights-of-way and easements, as well as topographic design and construction surveying, are focal points of Surveying’s Transportation division. Topographic surveys for engineering design, digital terrain modeling of bridges and overpasses, and establishing precise vertical and horizontal control for aerial mapping are handled under this division. With the addition of laser scanning technology, crews can safely collect data of busy roadways and intersections, and clearances for bridges and roadways can be accurately determined and mapped. We offer many alternative options for large scale projects to help reduce project cost and scheduling including aerial photogrammetry, aerial LiDAR mapping, mobile 3D laser mapping, and terrestrial 3D laser scanning.

Our LJA Surveying transportation division has supported TxDOT surveying needs for roadway, highway and bridge projects across the State as a prime contractor and subconsultant to design teams.

Collectively our licensed project managers have more than 60 years combined experience surveying for Federal, State, County and Municipal Transportation Departments on a wide variety of design projects.

LJA Surveying utilizes the latest state-of-the-art technology to efficiently and safely perform boundary, control surveys, aerial mapping, design survey and construction staking, including the latest in Bentley MicroStation/OpenRoads, and ESRI software packages for surveying and GIS related projects.

With our years of experience, knowledge and quality control processes related to transportation projects, we can focus and direct our dedicated team to make your project successful and provide high quality survey services to be delivered on schedule and budget.
