Preface
In response to requests from the trade and approval authorities, CSA authorized the organization of a Committee to prepare a national standard on scaffold falsework in construction. This Committee was formed with balanced representation from users, approval authorities and suppliers.
Much of the falsework used in the past for this purpose was empirically designed and lacked adequate safety margins which are often vital in temporary installations. As a result, the Committee decided to make this Standard primarily a users' specification.
The Committee studied various existing standards, reports, specifications and regulations dealing with this subject.
Documents which proved to be a valuable source of information were Special Publication SP4 **Formwork for Concrete of the American Concrete Institute as well as communiques of the Steel Scaffolding and Shoring Institute.
The Committee decided to separate Falsework and Access Scaffolding and prepare two Standards.
This Standard was prepared by the Committee on Scaffolding for Construction Purposes under the jurisdiction of the Sectional Committee on Structures and was formally approved by these Committees.
Scope
1.1
This Standard provides rules and requirements for the design, fabrication, erection, inspection, testing, maintenance, and use of falsework materials and components where they are erected to provide temporary vertical support for buildings and other structures during their construction, alteration or repair.
1.2
This Standard does not apply to:
(a) Suspended scaffolds or swing stages;
(b) Truck or vehicle mounted platforms;
(c) Access scaffolds;
