The Canadian Standards Association (CSA) sets the criteria for designing steel structures above 15m/ 50' height, and applies to all classes of communications service including AM, CATV, FM/TV, VHF, Microwave, Cellular/PCS, licenced & unlicensed frequency bands etc. Consequently, telecom structures that are 50' or higher and intended for a Canadian location must be designed according to the CSA-S37/01 specifications.
The standard utilizes wind pressure (in Pa.) based on 10, 30 or 100 years recurrence probability, but is not intended to cover all environmental conditions which exist at a particular location.
Why a CSA Tower in Canada?
- Public Safety & Interest: the main intention of the standard is to serve the public interest and protect the public through eliminating reducing risks of tower collapse and occurring damages
- Client Liability: the standard protects the client by minimizing potential risks and liabilities. Due to strict design criteria; a CSA compliant tower is not likely to fail once properly installed, thus drastically reducing liability risks for the client
- Construction Permits: towers for locations within a Canadian municipal area require permits, which need construction drawings, to be stamped by a professional engineer. In Canada, an engineer cannot stamp drawings that are not CSA compliant.
