Every land-side task runs off a single terrain model. Build the surface once, then contour it, grade it, subdivide it, run roads over it and drain it — without exporting between packages. BESPA Expert Systems is suitable for the preliminary design and feasibility study phase of civil infrastructure projects. Outputs are engineering aids, not certified designs: a qualified professional engineer must check and sign off any output before it is issued for construction.
