Pierce, FL 34946 As requested, a Roof Moisture Survey was completed by Cleary Inspection Service, Inc. (CIS) on the St. Lucie County — Logistic Center, located at 3855 South US Highway One, in Ft. Pierce, FL. PURPOSE OF THE SURVEY: Obtain visual and isotopic inspection data, to provide a non- destructive means to detect moisture by determining the amount of hydrogen within the layers of the roof using a nuclear (isotopic) Roof Moisture Gauge. The gauge neutrons can penetrate up to seven inches of roof and its coatings and the readings are of 7.5 seconds duration. METHOD: Hydrogen readings were taken at approximately five-foot intervals and the data recorded on the corresponding grid drawing. HYDROGEN READINGS: The purpose of the moisture test is to try to identify areas with wet roofing material. Following the field moisture tests, the customary procedure is for core samples to be taken at locations corresponding to readings that range from "low" to "high", in order to determine their moisture by weight content (gravimetric analysis). CODE CRITERIA: According to Florida Building Code (FBC) 2014, Chapter 15, Section 1521.4, not more than 25% of the total roof area or roof section of any existing building or structure shall be repaired, replaced or recovered in any 12 month period unless the entire existing roofing system or roof section is replaced or repaired to conform to requirements of this code. CORE SAMPLES: Core cuts were made to determine their moisture content (percentage by weight). Roof core samples, of a minimum of 2 inches in diameter, were taken down to the deck. The core samples were then transported to the laboratory in air -tight compartments to determine the type of roof components and percentage of moisture by weight. The detailed gravimetric results sheet is included with this report. FILE Uaupy Mailing Address: P.O. Box 2471, Palm Beach, FL 33480 Office: 1017 North "H" Street, Lake Worth, FL 33460 Tel.

Pierce, FL 34946 R`NSPBCT)ONseRVlce INC Page -2- ROOF GRAPH: The enclosed computerized graph was prepared from the data collected during inspection and gravimetric test performed in accordance with TAS 126. This graph separates moisture levels into four levels of dry to wet. The Florida Building Code sets allowable maximum limit of moisture in the roof system as 5% in the roof membrane and 8% in the insulation. (See chapter 15 section 1521.12) TEST SUMMARY: Top Gypsum Board Insulation: A total of 2415 nuclear field readings were recorded. The nuclear field readings ranged from 3 to16. Of the 2415 readings, 100% readings were found to be wet; over 8% moisture by weight content in the Top Gypsum Insulation (indicated in red). The Ton Gypsum Board does not meet current code for repair/recover. Bottom ISO Insulation: A total of 2415 nuclear field readings were recorded. The nuclear field readings ranged from 3 to16. Of the 2415 readings, III or 4.6% readings were found to be wet; over 8% moisture by weight content in the Bottom ISO Insulation (indicated in red). The Bottom ISO Insulation does meet current code for repair/recover. However, all wet insulation to be removed One Roof- Stele Ply Membrane over a Top Gypsum Board Insulation over a Bottom ISO Insulation over a Steel Roof Deck The test results presented here 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 due to exposure to the elements and roof top traffic.

Cleary Inspection Services, Inc. 1017 North 'H' Street Lake Worth, FL - 33460 Attention: Dear Ms. Cleary: Ms. Katherine Cleary March 1, 2018 Re.: Gravimetric Tests St. Lucie County Logistics Center 3855 South US Hwy-1 Ft. Pierce, FL - 34946 As requested, Forensic Engineering Consultants, Inc. (FEC) has completed gravimetric tests on the six roof samples delivered to our office. The tests were done in accordance with TAS-126. This report transmits the results of our laboratory tests. The subject facility is located at 3855 South US Hwy-1 in Ft. Pierce, Florida. We understand that eight core samples were obtained from the roof of the subject facility. In all, twenty four samples from eight roof cores were delivered to our office in sealed plastic bags with notations on the bags identifying the samples. We have used those same notations in our report. The roof samples were removed from the bags and weighed. They were then placed in an oven. The singe ply membrane samples were cooked at 150OF for over 24 hours, while the insulation samples were cooked at 230°F for over 24 hours. The samples were then removed from the oven, weighed again and the loss in moisture computed. The laboratory moisture content test results are given in the attached sheet. The sheet also indicates the reported sample locations. We appreciate the opportunity to be of service. If you have any other questions, please call. _ _ Sincerely,_ _- Forensic Engineering Consultants, Inc. u R. N.
