This is the third edition of CSA S472, Foundations. It supersedes the second edition, published in 1992, and the preliminary edition, published in 1989. This Standard is the second of five CSA Standards that form the Code for the design, construction, and installation of offshore structures.
The others are
(a) CSA S471, General requirements, design criteria, the environment, and loads;
(b) CSA S473, Steel structures;
(c) CSA S474, Concrete structures; and
(d) CAN/CSA-S475, Sea Operations.
This Standard addresses the geotechnical engineering aspects of
(a) gravity-base structures;
(b) fill structures;
(c) fill-retention structures; and
(d) pile-supported structures.
Specific considerations include site investigations, general design principles, the influences of soil and natural processes on the foundation components, and the geotechnical factors that affect the construction, installation, operation, and decommissioning of such structures.
Note: This Standard does not deal with ice as a resistive structural element (e.g., ice pads, rubble fields, and spray ice islands).
Each investigation, analysis, design activity, construction activity, inspection, and monitoring activity described in this Standard is to be performed by or under the supervision of one or more competent persons who have demonstrated experience relevant to the activity and are professionally licensed in Canada as engineers, geologists, or geophysicists.
In CSA Standards, 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; may is used to express an option or that which is permissible within the limits of the standard; and can is used to express possibility or capability.
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. Legends to equations and figures are considered requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.
