Crozier & Associates Designers in Collingwood were joined by their counterparts from Milton to take part in an advanced AutoCAD Civil 3D course held in-office at our HarbourEdge location this past March. As part of our on-going emphasis on professional development, the 3-day technical workshop focused on analysis, modeling and layout in a solutions-based approach to complex land development sites, subdivisions, grading, roads and drainage systems.
