The City of Calgary has developed a CAD (computer-aided design) standard to be used for engineering drawings on capital projects that impact City of Calgary horizontal infrastructure initiated on or after January 1, 2019. The Standard also applies to drawings for subdivision construction projects initiated on or after January 1, 2020. Any projects initiated prior to these dates are encouraged to use this CAD Standard. Usage of this standard is also encouraged for CAD representations of buildings and other vertical infrastructure projects. If you have suggestions or comments you can provide feedback by emailing us at CADinfo@calgary.ca.
