Why testing may be requested

Testing can provide useful, site-specific information before a full foundation installation or where a project team needs additional evidence about a proposed solution.

The test arrangement, direction, target load, number of locations and reporting requirement should be established for the individual project.

Testing is one part of verification

  • Review the proposed screw and installation location.
  • Define the test method and project requirement before attendance.
  • Record the setup, observations and measured information.
  • Interpret the result in the context of the structure and site.

Limits of a test

A test at one point does not make every part of a variable site identical. Results should not be separated from location, setup, ground conditions or the tested component.

Testing does not remove the need for appropriate design, installation control or engineering judgement where those are required.

RESPONSIBLE USE

Project requirements vary. A booking request is reviewed before any test arrangement is confirmed.
