Scope 1.1.1 Scope of Code The OHBDC (MTO 1991) was written for application within Ontario. CSA S6 (CSa
1988) was generated with interprovincial cooperation for use in the other
Provinces of Canada and was largely derived from the preceding OHBDC edition.
The Provinces and the CSA then agreed that the successor edition to both codes
would be the CHBDC, published by the CSA. The Code has been written using the
earlier codes as source documents and with the intention of retaining
continuity. The scope of the Code is a little broader than that of the 3rd and
last edition of the OHBDC (MTO 1991). Long span bridges and movable bridges are
included. In addition to incorporating newer technology, more emphasis is
placed on criteria related to seismic design, durability, access for inspection
and maintenance.
The Code Scope statement lists types of structures to which the Code is not
intended to apply. The list is not exhaustive. The application of the Code to
the types of structures listed is not precluded where the Owner or the
Authority having jurisdiction over the structure has designated all or part of
the Code as being applicable.
