Construction Testing | French Engineering, LLC

French Engineering is experienced in and capable of sampling and conducting a variety of different tests in the field for numerous projects across the United and States and North America.

We have the equipment and experience to conduct testing in accordance with standard test methods and procedures promulgated by the American Society for Testing and Materials (ASTM), American Architectural Manufacturers Association (AAMA), and Factory Mutual (FM), Exterior Insulation Manufacturers Association (EIMA), International Concrete Repair Institute (ICRI), Sealants, Waterproofing and Restoration Institute (SWRI), National Association of Home Builders (NAHB), and RILEM. Whether you project requires analysis of materials provided and systems installed, or if the performance of any building envelope component is in question, French Engineering can perform the appropriate testing to assist in evaluating any deficiencies or in confirming compliance with prescribed criteria. French Engineering is capable of providing testing in accordance with the following test protocols:

ASTM E547: Test Method for Water Penetration of Exterior Windows, Curtain Walls, and Doors by Cyclic Static Air Pressure Differential
ASTM E783: Field Measurement of Air Leakage Through Installed Exterior Windows and Doors
ASTM E907: Field Testing for Uplift Resistance of Adhered Membrane Roofing Systems
ASTM E1105: Field Determination of Water Penetration of Installed Exterior Windows, Curtain Walls, and Doors by Uniform or Cyclic Static Air Pressure Difference
AAMA 501.2: Field Check of Metal Storefronts, Curtain Walls, and Sloped Glazing Systems for Water Leakage
AAMA 502-90: Field Testing of Windows and Sliding Glass Doors
FM 1-52: Roof Uplift Testing (Tripod Method)
FM 1-52: Roof Uplift Testing (Bubble Method)
NAHB Moisture Test for Exterior Insulation and Finish System (EIFS) Assemblies
RILEM tube moisture absorption test
Concrete chloride content
Concrete mix and compressive strength
Concrete performance - anomalies
Reinforcing steel corrosion
Performance of post-tensioned strands
Sealant field adhesion testing

In addition to the field testing outlined above, French Engineering is experienced and knowledgeable in collecting samples and coordinating a myriad of different laboratory testing for a variety of different purposes, including diagnostic, as well as forensic. Our experience and knowledge of appropriate ASTM test methods and standards allows us to "customize" a test program designed to specifically assess the conditions at your project. Due to the wide variety of tests and procedures available, please contact us to discuss your specific needs.

Non-Destructive Moisture Surveys

Over the years, French Engineering has had experience with a variety of non-destructive roof moisture surveys methods, including infrared (thermographic imaging), radioactive isotope (nuclear), resistivity, and capacitance methods. Our experience allows us to determine which method would be the best for your project in order to accurately assess the severity and location of moisture within the roof insulation and deck materials of your buildings. This information can be invaluable in developing a prudent replacement and repair scheme that may be capable of saving and renovating the original roof system at substantial savings when compared to total replacement options. In addition, non-destructive roof moisture surveys are capable of pin-pointing where anomalies and problem areas may exist within the roof system, so effective repairs may be made at the "right" locations.

In addition to roof moisture surveys, French Engineering has extensive experience in performing or coordinating non-destructive moisture surveys and NAHB moisture tests for various types of wall cladding systems, including plaster, Exterior Insulation and Finish Systems, and lapped board siding. This type of testing may be helpful in diagnosing and locating thermal bridges, wet spots, water infiltration sources, and areas of retained moisture. Once known, these locations may be properly addressed utilizing appropriate and effective repair techniques.

Infrared Thermography

Our experience includes non-destructive condition surveys using digital infrared (IR) thermography. Infrared thermography allows French Engineering to pinpoint thermal anomalies on building materials, which may translate to underlying construction deficiencies or deteriorated building components.

Infrared thermography is quickly growing in popularity throughout the United States due to its cost-effectiveness and diverse range of applications. Greater efficiency and accuracy translates into savings in time and money for building owners during and after the survey process.

French Engineering infrared thermography services include:

Roof Condition Surveys
Cladding Condition Surveys
Quality Assurance Inspections during construction
Condition monitoring through periodic inspections
Supplemental analysis during field leak test services
Energy Loss Surveys (air leakage, insulation anomalies, etc.)
Mechanical System Surveys
Electrical Distribution System Surveys
French Engineering is a member of IRINFO.org and maintains a staff of qualified infrared thermographers certified by The Infraspection Institute.
