Take a look at a few of our projects and what our customers have to say, and learn how Zahner & Associates can work for you.

Kiln Design Project

Zahner & Associates, Inc., was contracted to provided 3D laser scanning services to aid in the design of a new Kiln to be built within an existing facility. We provided 3D laser scanning and a colorized point cloud of the plant to capture critical tie points for the construction project. After the design was completed and construction began, we were then contracted to provide third party verification to assist in maintaining accuracy throughout construction.

Zahner & Associates provided Engineering and Survey services for construction plans for the replacement of private and shared sidewalks for 31 federal housing buildings consisting of 102 units. This included ADA design of stairs, railings, curb ramp and switchback ramp. The design included construction details, profiles, and sections. The project is expected to be completed by fall 2017.

Downtown Stadium Project

Zahner & Associates was proud to partner our Mobile LiDar services with the Clayco Construction team for the planning of the new downtown stadium. With time and safety playing an important role, Mobil Lidar offered many advantages-



  • no personnel in the streets
  • no shutting down traffic lanes
  • provided clearances to powerlines and other utilities in a discreet and timely manner.



Bois Brule Levee

In the Spring of 2016 Zahner & Associates, Inc. was contacted by the Levee District and the Corps of Engineers to utilize our Mobile LiDar services to survey the low points (problem areas) on the 32 miles of the levee in Bois Brule. Timing was a major factor. Every minute counted as the Mississippi River flood waters were rising.  Zahner & Associates was able to survey and assess the problem areas and start staking a solution within 24 hours.
