(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. Sincerely, Keith LeBlanc, P.E. Z Lo yc Federal Engineering and Testing, nc. Florida Reg.
