OS2 Structural Safety



Intent 1:

To limit the probability that the method of design of foundations, excavations and soil- and rock-retaining structures will not be based on:

  • a subsurface investigation carried out in accordance with Section¬†4.2., and
  • generally accepted geotechnical and civil engineering principles, established local practice or in situ testing of foundation units.

This is to limit the probability of structural failure, including excavation collapse, which could lead to harm to persons.

Intent 2:

To facilitate, through qualification of persons involved with the design and testing, the determination of compliance with this requirement.
