number, pertinent dimensions, materials, and method of securing ties. Each
drawing shall bear the seal of a licensed professional engineer in Illinois.
2)Â Â Â Â Â Â Â Â Test

the anchor and all tiedown equipment meet the requirements of this Section.Â
Each piece of equipment must be tested a minimum of three times and be shown to
meet the requirements of Section 870.200. The tests must be conducted with the
equipment installed according to the installation instructions.

copy of the installation instructions for each anchor must accompany all
anchors when sold. For ground anchors, the instructions shall include
information as to the holding capability of the soils in which the anchor is
certified to be installed, the method of installation, the type and size of
stabilization devices required, the amount of pre-loading, and the method of
tension adjustment after installation. The instructions for installation must
be consistent with the testing of the equipment, especially with regard to the
angle and depth of installation of ground anchors. The instructions for
concrete anchors shall specify the minimum amount of concrete required, the
distance from the edge of the concrete to the anchor and the compressive
strength of the concrete. A copy of all instructions, including any revisions,
must be submitted prior to the issuance of approval.

anchor equipment will be rated at the soil holding capability of tests on file
and not soil class ratings.
