1. Conference Title June 23, 2010 Location Hartford, CT 1 © 2010 H. Ross Clements, AIA All Rights Reserved Forensic Tools 101 Presented By: H. Ross Clements, AIA Construction Science and Engineering, Inc. Westminster, South Carolina

2. A Little about Me… Presenter: H. Ross Clements, AIA Employed by: Construction Science and Engineering, Inc. 218 E. Main St. Westminster, SC 29693 Education: Bachelor of Architecture University of Tennessee College of Architecture and Design, 2001 Helping my Dad with his bookshelves is my earliest memory of learning to work with building materials.

3. As a Forensic Architect I am asked to: Determine cause of damage Determine extent of damage Determine necessary repairs Determine who is responsible for loss or damage

4. A Little about CSE… Staff located in Westminster, SC Forensic Architecture and Engineering Firm 50/50 Defense/Plaintiff

5. Defense Case Outline:

6. Common Tools Dictaphone Camera Tape Measure Probes Sharpie, Chalk, Crayon Utility Knife Flashlight Blue Tape Level Mirror Scale

7. Specialty Diagnostic Equipment Observant Eyes, Attentive Ears, and an Objective Mind to approach each case…

8. Specialty Diagnostic Equipment Moisture Meter IR Camera Metal Detector Boroscope/Camera Water Test Kit Roof Core Crack Monitor Slip Meter Adhesion Tester Cone Penetrometer Microscope Withdrawal Tester EIFS Pull Test Database: Historical Library of Codes and Industry Standards

9. Moisture Meter Pin-type meters and Pinless meters Can provide a qualitative indication of the substrate conditions, helpful in determining if damage exists behind cladding

10. IR Camera

11. Creates an image using infrared radiation rather than visible light Used to capture images showing potential problems not apparent on the surface

12. Metal Detector

13. Used to detect and mark the locations of existing brick ties in masonry walls

14. Boroscope/Camera Can obtain images of small cavities Used to capture images of spaces which may be difficult to access By drilling a small opening and inserting the camera, images may be obtained which can determine where damage exists

15. Boroscope/Camera

16. Water Test Kit Consists items used to test an installed window unit for water leakage in accordance with AAMA 501.2 AAMA test method used to determine the installed condition of window units in existing buildings Determines a variety of issues: ◦ flashing defects ◦ window installation defects ◦ window component failures ◦ window manufacturing defects

17. Water Test Kit

18. Moisture Test Strips Used to show moisture in areas in which water is hard to see Strip changes color when put into contact with water

19. Roof Core Sampler Used to take samples from a low sloped roof Saw teeth at the end of the cylinder allow the cylinder to be pushed into the roof and ultimately remove a sample of the layers

20. Crack Monitor

21. Once positioned over a crack, the crosshairs on the two plates of the crack monitor will shift when slabs move, making movement easier to see Used in cases involving differential settlement of foundations. Progress chart records movement Once a pattern of movement is established on the Progress Chart, forensic professionals can then decide what remedial action is needed.

22. Slip Resistance Meter

23. Measures the resistance to slipping on a floor covering Used to test slippage potential ASTM

24. Paint Adhesion Tester (PAT) Conducts adhesion tests on paints applied to a flat, uniform surface in accordance with ASTM Test Method D 3359, Method B and DIN Standard No. 53151 Used in cases involving coating failures Results can be used to determine the cause of the coating failure

25. Microscope Used to…

26. PosiPen Used for measuring dry non-magnetic coatings on steel and the ferrite content in metal.

27. Smoke Pen Used to dispense test smoke smoke-emitting wick is inserted into the clutch pencil and ignited Used for a variety of testing applications: ◦Leaks in duct work, heat exchangers, furnaces, plumbing ◦Air movement & ventilation systems ◦Turbulence around fume hoods ◦Duct mounted smoke detectors ◦Fume evacuation from gas heaters, etc ◦Leakage in ventilation systems ◦Leakage in drainage systems ◦Exhaust fans

28. Withdrawal Tester Assesses the adequacy of the installation and overall effects of deterioration, such as moisture, on the EIFS wall assembly (as opposed to small localized areas of degradation)
