Job Order# 20R121
Pursuant to your request, Federal Engineering
&Testing, Inc. (FE&T)
has performed a field
withdrawal resistance
test in compliance with Testing Application
Standard TAS-105 and
the Florida Building
Code High Velocity
Hurricane Zone at the above referenced site.
The purpose of our test
was to determine the
uplift capacity of the
mechanical fasteners at the above referenced project. FE&T is a
Miami Dade Certified Testing Laboratory
(Certification #18-1105.02).
On 02/19/2020 our field representative visited the referenced site and conducted thirty-one (31) field withdrawal
resistance tests on the OMG #12 screw fasteners into the metal roof deck. All tests were found in compliance with
the Florida Building Code and TAS405. See attached copies of TAS-105 forms with test results.
The test results presented reflect the condition of the roof system at the time of the test. These results are time and
sample dependent since roof conditions are continuously changing one to exposure to the elements. All tests were
conducted according to the Florida Building Code Test Protocol TAS405 using a calibrated Comten Industries
Fastener Tester Model No.DFG 2W2000 (see attached calibration).
FE&T is an independent third party providing un-biased testing
information and results.
FE&T is not affiliated with
our client nor do we have any fmancial interest
in the project or
determination of the test
results.
Federal Engineering &Testing, Inc., appreciates the opportunity to be of service to you at this phase of your project.
If you have am/; questions or comments, please give us a call. It has been a pleasure working with you and look
forward to doing so in the near future.
