SiteWorx/OS

SiteWorx/OS helps you streamline the complex process of site excavation and earthwork estimating. You can import digital PDF files or scan paper blueprints to perform high-precision takeoffs that calculate cut and fill volumes, topsoil stripping, and subgrade materials. The software creates a 3D model of your site, allowing you to visualize the existing and proposed terrain to identify potential errors before you ever move a single yard of dirt.

You can generate detailed reports and high-resolution graphics to support your bids and provide clear documentation for field crews. Whether you are a site contractor, land developer, or estimator, the platform simplifies the transition from 2D drawings to 3D site analysis. It eliminates manual calculation errors and significantly reduces the time you spend on complex grading projects.
