Purpose
Site Engineer Tools is a collection of focused browser-based calculation aids for setting out, drainage, levels and construction quantities. The initial release deliberately uses static files and client-side calculations so the site can operate without accounts, databases or paid APIs.
Calculation approach
Core formulas are isolated in a tested JavaScript module. Pages show assumptions and conventions beside the result, and example inputs provide a quick sense check. The tools are intended for independent checking rather than replacing controlled design information, competent review or project-specific method statements.
Privacy by design
Coordinate text and calculator inputs remain on the device for the calculations currently included. No user account is required. See the privacy page before enabling any future analytics or advertising service.
