INSTALLATION RECORD SUBMITTALS
14.1 The Installing Contractor shall provide the Owner copies of the individual helical anchor
installation records within 24 hours after each installation is completed. Formal copies shall
be submitted within 30 days following the completion of the helical anchor installation. These
installation records shall include, but are not limited to, the following information:
14.1.1 Date and time of installation
14.1.2 Location of helical anchor and anchor identification number
14.1.3 Installed helical anchor model and configuration
14.1.4 Termination depth, anchor head depth, and length of installed anchor
14.1.5 Actual inclination of the anchor
14.1.6 Final torsional resistance
14.1.7 Calculated geotechnical capacity based on final torsional resistance
14.1.8 Comments pertaining to interruptions, obstructions, or other relevant information

FIELD TENSION LOAD TESTING
15.1 If field tension load testing is required, the Installing Contractor shall furnish all labor, equipment
and pre-production helical anchors necessary to accomplish the testing as shown in the
approved anchor design documentation. Installing Contractor shall apply the specified loads
for the specified durations and record the specified data, for the specified number of anchors.
No deviations from the test plan(s) will be allowed without explicit approval in writing from the
Owner. Anchor testing shall be in general accordance with the ASTM D3689 quick test method
and the following criteria:
15.1.1 Failure criteria shall be in accordance with AC358 and is when plunging occurs or when
the net deflection exceeds 10% of the average helix plate diameter, whichever occurs
first.
15.1.2 An alignment load equal to 5% of the anticipated failure load or maximum anticipated
test load may be applied prior to the start of the test to take out slack in the load test
frame.
15.1.3 Loading increments shall be performed at 5% of the anticipated failure load or maximum
anticipated test load with a minimum hold time of 4 minutes at each increment.
15.1.4 Upon completion of the maximum test load hold increment, the anchor shall be unloaded
in 5 to 10 even increments with minimum hold times of 4 minutes at each increment.
15.2 Installing Contractor shall provide the Owner copies of raw field test data within 24 hours after
the completion of each load test. Formal test reports shall be submitted within 30 days following
test completion. Formal test reports shall include the following information:
15.2.1 Name of project and Installing Contractor’s representative(s) present during load testing.
15.2.2 Name of manufacturer’s representative(s) present during load testing, if any.
