As requested, on June 27, 2019, Mayes Testing Engineers performed load testing of
hold-down anchors at the above referenced project at 18111 84th Avenue West in Seattle,
Washington.
Background
The Residence at 18111 84th Avenue West is currently under construction. Part of the
construction includes the use Simpson Strong -Tie HD713 and HD12 hold-downs for seismic
and wind loads. We understand that these anchors did not receive inspection during their
installation. Thus, load testing of the anchors was required for permissible use.
Test Procedures
There were approximately eight H D713 and eight
HD12 anchors installed; two of each
(approximately 25%) were selected for testing in -A.
conjunction with the contractor based on
accessibility.
The test load was applied via a calibrated
Enerpac RCH-302 thru-hole hydraulic ram and
digital gauge assembly (shown right). In
accordance with ASTM E3121 load testing
procedures, we also used a reaction beam to
distribute the load away from the substrate in
which a failure cone could develop.
We understand the HD713 anchors prescribed a
test load of 5,600 pounds -force (lb-f), while the
HD12 anchors were prescribed a test load of
20,000 lb-f. All anchors were tested at their
prescribed loads for 5 minutes or until failure,
whichever came first.

Test Results
All anchors tested held their required loads for the minimum 5-minute duration without
failure or indication of overstress. The general locations of the tested anchors are shown on
the attached plan.
We trust this provides you with the information you require at this time.
Respectfully Submitted,
