Description / Abstract:

This Standard provides rules and requirements for the design, fabrication, erection, inspection, testing, maintenance, and use of falsework and formwork materials, components, and systems where they are erected to provide temporary vertical and lateral support or containment of freshly placed concrete for buildings and other structures during their construction, alteration, or repair, and includes the reshore of new slab systems that have not achieved full strength. This Standard also covers the design of perimeter enclosure systems.


1) Supplementary rules or requirements may be necessary for unusual types of falsework or formwork that

a) are exposed to unusual environments or features;

b) employ materials or procedures not covered in this Standard; and

c) are intended to be used many times for precasting applications.

2) Similar material can be found in AS 3600, AS 3610, BS 5975, and BS EN 12812.

This Standard is structured and organized so that it may be used with either working stress or limit states design standards and concepts.

This Standard does not apply to

a) suspended scaffolds or swing stages;

b) truck or vehicle mounted platforms;

c) access scaffolds;

d) design of concrete structures;

e) chimney jump forms; and

f) demolition.

In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the Standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
