Identify water intrusion problems in your multi-family, commercial, industrial or institutional building in Raleigh, North Carolina before they cause serious damage with infrared inspection services from Building Diagnostics Group.
Building Diagnostics Group (BDG) is a multifaceted consulting firm, founded in 2002, that specializes in infrared building science, aerial thermography, and water testing procedures that enable us to identify the cause and origin of most roof and building failures.
The President of BDG, Robert Scherer, has over 25 years of residential and commercial construction experience and is a pioneer in the field of moisture intrusion and building defect investigations with the use of infrared thermography. He is a Certified Indoor Environmentalist, Certified Mold Inspector, an ITC Certified Level III Thermographer with over 15 years of thermography experience and is certified in Advanced Building Diagnostics.
Our experienced team has performed services on hundreds of multi-family and commercial properties and inspected in excess of 50 million square feet, identifying significant hidden building defects that have cost from $2 to $5 million dollars in underlying structural repairs.
BDG services include:
- Exterior building inspections
- Commercial roof surveys
- Interior building inspections
- Cell Fill (CMU) evaluations
- EIFS inspections
- Electrical inspections
- Energy audits
The FAA has granted BDG a 14 CFR 107.29 Daylight Operation Waiver. This waiver allows us to perform aerial infrared roof inspections and other nighttime missions throughout the United States.
Why Infrared Thermography?
Infrared thermography (IR) uses specialized thermography cameras to measure the thermal energy emitted from an object. Thermal energy is light that is not visible because its wavelength is too long to be detected by the human eye. Unlike visible light, in the infrared world, everything with a temperature above absolute zero emits heat.
IR thermography is the only diagnostic tool that lets you instantly visualize faults due to thermal patterns, enabling you to maintain the reliability of electrical and mechanical systems and resolve issues before it is too late. Thermography also easily detects water penetrating a building envelope due to the thermal differences between wet building materials and the adjacent dry materials.
Causes of Water Intrusion
The basic causes of moisture intrusion into buildings are:
- Rainwater/groundwater intrusion: In both hot, humid and temperate climates, rainwater leaks and groundwater infiltration are major sources of building moisture and mold-related problems.
- Intrusion of moisture-laden air from outside: Humid air from outside can be introduced into building cavities by wind and through HVAC systems. This can be a particularly serious problem in hot, humid climates.
- Water vapor diffusion: Differential vapor pressure between the interior and exterior of a building can cause water vapor to diffuse through the building envelope. This can be a significant problem in cold climates.
BDG performs field-testing procedures relative to evaluating the performance of installed windows, doors, storefront, curtain walls, sloped glazing systems, skylights, ribbon windows, and exterior building facades for new construction quality assurance and diagnostic services to determine the cause of water intrusions.
