Existing-Ground Data That Keeps Design Moving
Move from existing conditions to design with dense, high-accuracy terrain data. Utah LiDAR supports civil engineering firms with point clouds, existing-ground surfaces, contours, breaklines, and CAD-compatible files for grading, drainage, roadway, utility, and land-development projects.
Why civil firms use LiDAR
Better Existing Data Supports Better Design
Design schedules can stall when field data is incomplete, delayed, or too sparse to represent complex terrain. Drone LiDAR captures dense elevation information across large project areas and difficult terrain, giving design teams a more complete representation of existing conditions.
Collection and processing are scoped around the engineer's intended use, required outputs, coordinate system, and professional-surveying requirements.
Design can't start until existing conditions are known. When survey is the bottleneck, schedules slip and fees get eaten by waiting.
We collect dense, RTK-controlled terrain data over corridors, sites, and drainages and deliver surfaces your design team can load directly into Civil 3D.

Common questions
Civil Engineering Firms LiDAR FAQs
Can LiDAR data be used in Civil 3D?
Yes. Surfaces, contours, breaklines, and linework are delivered in Civil 3D-compatible formats such as LandXML, DWG, DXF, and CSV so they import as usable design data rather than a static image.
Is LiDAR suitable for grading and drainage design?
Dense bare-earth surfaces with defined breaklines support grading and drainage analysis well. The required accuracy and contour interval should be defined before collection so flight planning and control match the intended use.
Can LiDAR produce bare-earth terrain beneath vegetation?
LiDAR records multiple returns per pulse, so a portion of the pulses reach the ground between vegetation. Ground return density drops under heavy canopy, which is accounted for in flight height, overlap, and point density.
What information does an engineer need to provide?
Project limits, access details, coordinate system and datum, accuracy expectations, desired contour interval, existing control, and the file formats your design team needs.
Can existing conditions be collected before final design?
Yes, and earlier is usually better. Preliminary collection supports feasibility, layout, and grading concepts, and the site can be recollected later if conditions change materially.
Can LiDAR surfaces be compared with a proposed design?
Yes. A collected existing-ground surface can be compared against your design or grading model to produce cut, fill, net quantities, and elevation-difference exhibits.
What contour intervals are available?
Interval is set by the project. One-foot contours are common for site and grading work, with larger intervals used on broad terrain studies. The interval should match the accuracy of the collected data, not exceed it.
Does Utah LiDAR provide stamped survey documents?
No. Utah LiDAR provides data collection and preliminary processing. Boundary determination, certified surveys, and stamped documents require a Professional Land Surveyor licensed in the project state.
Other industries
All deliverables are provided as preliminary or supporting data. Stamped or permitted use requires review and certification by a licensed Professional Land Surveyor.
