For seventy years, the Strange Bros. name has been synonymous with site grading. Today, what sets Strange Bros. apart is the ability to manage your dirt … not just move it.
Site grading typically begins with a detailed CAD file created by the civil engineering team that addresses storm water, curbing and finished floor elevations. Strange Bros. integrates that CAD file into a 3D surface model that’s imported directly into our grading equipment, along with GPS software.
Drone Interface
This surface model is also integrated with our drone software. Once the surface is cleared, we can fly the site for topography using 2D photogrammetry that takes an overlapped pattern of photo-images. Typically, in less than 45 minutes we can determine precisely how many cubic yards of dirt are required to get to (or remove from) the desired surface. These intricate calculations, applied to a thousand cubic yards of haul off or import, can create thousands of dollars in savings in time and fuel costs.
Strange Bros. handles everything from the tying into the boundary survey all the way through to as-builts for the storm system, curbing and getting the property ready for paving. We determine which utility company will handle sewer and storm drainage.
Our advanced drone interface provides high-resolution, up-to-date aerial photography throughout every phase of a project—before, during, and after sitework. This technology allows us to verify that our grading work aligns precisely with design specifications, ensuring accuracy and accountability.
In addition to quality control, drone imagery gives clients a clear visual timeline of site progress. Even for those frequently on site, these overhead perspectives reveal changes that may not be obvious from the ground—especially on large-scale projects. It’s a powerful tool for communication, documentation, and peace of mind.
