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.

ZWCAD Civil

ZWCAD Civil gives you a specialized toolkit built on the familiar ZWCAD platform, specifically designed to handle the heavy lifting of civil engineering projects. You can transform raw survey data into detailed digital terrain models and generate contour lines automatically. Whether you are designing roads, managing land leveling, or calculating earthwork volumes, the software automates the repetitive geometric calculations that usually eat up your billable hours.

You can work within a familiar DWG environment, meaning there is no need to relearn basic drafting commands. The platform focuses on accuracy and speed for infrastructure tasks like profile drawing and cross-section generation. It is an ideal solution for small to mid-sized engineering firms and land surveyors who need professional-grade civil tools without the steep price tag or complexity of high-end enterprise suites.
