1.1 General
This Standard covers the load test procedure for evaluating the strength and deformation performance of wood roof trusses intended for use in housing and small buildings as defined in Part 9 of the National Building Code of Canada.
Note: Part 9 of the National Building Code of Canada provides detailed requirements for the construction of houses and small buildings up to 600 m² in building area and 3 storeys in building he ight and applies to all occupancies except assembly, institutional, and high-hazard industrial.
1.2 This Standard does not stipulate mandatory performance criteria (see Appendix A for acceptable performance criteria).
1.3 Intent of Test
This load test procedure is intended to evaluate the adequacy of wood roof truss designs and is not intended as a quality control test. The procedure may, however, be used for retesting production run samples in cases where the quality of the truss is in dispute.
Note: It is recognized that measures to ensure the quality of production of trusses must be maintained for on-going production of designs acceptable under this Standard.
1.4 Limitations
Assemblies to be tested by this procedure are limited to:
(a) Triangulated trusses having a maximum span of 12 m; or
(b) Bowstring or lenticular trusses having a maximum span of 4.3 m; whose members are connected using mechanical connectors or nailed gu sset plates and which are intended to be installed at a maximum spacing of 600 mm on centres and in such a manner that the top chords are suitably sheathed or braced to prevent lateral buckling.

This is the second edition of CSA S269.1, Falsework and formwork. It supersedes the previous edition published in 1975 under the title Falsework for Construction Purposes.
The following are the significant changes from the previous edition of this Standard:
a) Provisions are now included for limit states design (LSD) while keeping provisions for allowable stress design (ASD), thereby letting the designer choose the method most appropriate. The aim in including LSD requirements is to be at least as safe as the existing ASD requirements.
b) This Standard combines the previous CSA S269.1 (dealing with falsework) and CSA S269.3 (dealing with formwork) into one Standard to eliminate redundancy and improve user readability.
c) A section on specialized formwork and falsework has been added.
d) A new Annex A on plywood has been added.
e) Updates have been made to scope, definitions, reference Standards, design, drawings, site activities, testing, figures, and tables. The updates will make this Standard more current and compatible with other similar documents.

• the requirements for absolute spatial positioning (i.e., horizontal and vertical datums) have been revised;
• the accuracy requirements for as-builts have been streamlined in Table 1 (see Clauses 5.5 and 5.6.2 and Figures 2 to 6) and Table 2 (see Clause 5.7 and Figures 2 to 6);
• the measurement requirement has been revised to include the lowest point below grade for vertical structures (i.e., the bottom of the utility pole);
• the obligation to identify third-party data sources has been expanded within the title block of shared maps and drawings;
• the material abbreviations have been revised to better align with other industry standards;
• the specific utility infrastructure requirements and graphical representations for mapping records have been revised;
• Clause A.4.5.4.2.2 has been expanded to provide guidance on leveraging the resolution of mapping discrepancies to drive the improvement of mapping records; and

These Standards and Guidelines have been developed as a resource for designers and owners of ferry boarding facilities operated in Canadian waters. Their purpose is to provide a consolidated standard of minimum requirements and guidelines for the design, operation, inspection, and maintenance of such facilities. Additionally, they are intended to encompass items not addressed in other standards.
These Standards reflect the diversity of ferry boarding facilities and their operating environments throughout Canada and are therefore based on general principles and objectives. Requirements are expressed in broad terms so that they may have the widest possible national application.
To accommodate the diversity of applications in Canada, the provisions set out by these Standards combine both code requirements and guidelines. In general, the design Standard (CSA S826.1) and the inspection Standard (CSA S826.3) are Standards expressed in mandatory language. The operations (CSA S826.2) and maintenance (CSA S826.4) Guidelines are expressed in recommendatory language.
