Helical Foundation Systems

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.
