Building Forensics
Problems identified:
• EIFS
• Siding
• Structural defects
• Moisture
![Page 4: Presentation by SJA at Southtowne Rotary](https://reader036.vdocuments.mx/reader036/viewer/2022070315/554ed7bdb4c905d1158b478e/html5/thumbnails/4.jpg)
EIFS (exterior insulation finishing system)
• Evaluation • Very few certified evaluators
• Installation• Manufacturer Specifications
• Type• Since 1996
• Drainable Vapor Barrier Required• Flashing/Caulking Inspection
Required
• Present Day• Can’t install it
Do Not Confuse With Hard Coat Stucco

Siding
Class Action Lawsuits• Louisiana Pacific-“Smart Lap”
• Attended first trial in 1996
• 800,000+ houses
• Weyco-Class Action• Masonite-“Omniwood”

Structural Defects
Identify building system parts: • Trusses• Roof trusses • Wall and floor framing • Venting• Electrical • Heating • Footing • Foundation• Finishes

Structural Issues
The Building Envelope
The building envelope encloses and weatherizes the house.Any portion can fail and these are areas where moisture intrusion happens because of poor application and maintenance.
• Siding
• Flashing
• Doors and Windows
• Gutters, Drains, Downspouts
• Roofing
• Chimney Caps
• Insulation
• Sealant
• Vapor Barrier

Moisture
Sick Building Syndrome•Phase 1 mold evaluation
(What kind of mold is present?)• Phase 2 evaluation can only be done by a
Certified Industrial Hygienist
•Product and Systems Evaluation (What is the cause?)
• HVAC System
•Remediate (protocol to prevent cross-contamination)
•OSHA analysis (in some cases)

Analyze Findings (cause)
• Site analysis (soils)• Drainage• Component parts• Research products• Structural analysis (engineering
review)
Did a product fail? Or, was it installed improperly? (Workmanship)

Foundation System
• Concrete is porous and sucks up water• Concrete slabs trap vapor…older construction has
no vapor barrier
