Methodologies For Forensic Investigation Of Construction Defects

Construction defects happen. Sometimes it's a design or installation error, other times the building components simply fail. We use proven methodologies to conduct our forensic investigations and testing, so that we may provide you with expert opinions that hold up under scrutiny.

While many recognized methodologies exist for the investigation of various failures and defects, we understand and apply the most appropriate for your case and circumstances.

We often utilize the following investigation and testing standards:

ASTM Standards:
  • ASTM E2128 - Standard Guide for Evaluating Water Leakage of Building Walls
  • ASTM D7053 - Standard Guide for Determining and Evaluating Causes of Water Leakage of Low-Sloped Roofs
  • ASTM D5957 -  Standard Guide for Flood Testing Horizontal Waterproofing Installations
  • ASTM E1105 - Standard Test Method for Field Determination of Water Penetration of Installed Exterior Windows, Skylights, Doors, and Curtain Walls, by Uniform or Cyclic Static Air Pressure Difference
AAMA Standards:
  • AAMA 511 - Voluntary Guideline for Forensic Water Penetration Testing of Fenestration Products
  • AAMA 501.2 - Quality Assurance and Diagnostic Water Leakage Field Check of Installed Storefronts, Curtain Walls and Sloped Glazing Systems

The application of appropriate standards, combined with our years of experience in the field focusing solely on the building envelope, sets us apart from others
