The engineering problem

A city network, end to end

A city network spanning more than 1,000 km of pipeline and 20,000 fittings required survey integration, hydraulic simulation and detailed CAD layout.

We developed a novel AI-driven engineering design approach to support our client's vision to grow 4× with no increase in manpower.

The workflow

Survey, simulation, layout

Survey data is integrated into GIS, pipe sizes are simulated, and the design layout is produced with every fitting, with Claude generating the CAD.

  1. Step 1

    Survey integrated into GIS

    ArcGIS

  2. Step 2

    Simulation on pipe size

    WaterGems

  3. Step 3

    Design layout with all fittings

    AutoCAD

Three-step workflow: a city survey integrated into GIS in ArcGIS, a pipe-size simulation in WaterGems, and the design layout with all fittings in AutoCAD.
From survey to layout: GIS integration, hydraulic simulation and AI-generated CAD.

The result

From 2 months to 48 hours

First-cut design moved from two months to 48 hours. Most of the 48 hours that remain is engineering simulation time.

The workflow also added an auditable process around the generated design.

Capabilities involved

  • AI-generated CAD
  • GIS survey integration
  • Hydraulic simulation
  • Auditable design workflow
