Automated Ground Floor Slab Level Calculator for Large-Scale Housing, Integrated with AutoCAD

The Challenge

On a large housing development with hundreds of plots, setting each unit's finished floor / ground slab level — balancing site levels, drainage falls, flood freeboard and access gradients — was a repetitive manual exercise, error-prone and slow to update whenever the site layout changed.

The Solution

We built a tool that automatically calculates the optimum ground floor slab level for every plot from the site survey and design inputs, integrated directly with Autodesk AutoCAD — reading plot and level data from the drawings and writing the calculated slab levels back. Levels stayed consistent across the whole development and updated instantly as the layout evolved.
