Functional Performance Testing (FPT)

Functional Performance Testing (FTP) in the construction industry tests air and moisture movement through a building’s enclosure. Performing these tests verifies that your building components are installed correctly and operate as designed. Feel confident knowing your building enclosure is working correctly to avoid future moisture infiltration problems.

Are you getting what you paid for?

At BEPG, we think it’s a good idea to verify that you’re getting the expected features of your building’s design. We use industry-standard functional performance testing (FPT) to test a building’s enclosure to confirm protection from the exterior elements.

Besides functional performance testing, what benefit does a building enclosure specialist bring to your project? We bring years of experience assessing, diagnosing, and designing repairs for buildings with moisture problems. This unique perspective enables us to know what works and what doesn’t. Consequently, we apply this perspective and knowledge to new construction projects to help the Owners avoid problems.

New Construction

New construction isn’t cheap. That’s why it’s essential to do it right the first time. Building enclosure material design and installation is a discipline itself. However, the number of possible enclosure combinations is staggering because of the numerous available materials and manufacturers. We are here to help make it simple. With over 50 years of combined roofing, waterproofing, and exterior wall consulting, we’ve heard of most possible systems or materials.

Don’t Believe Us? We’ll Test It.

Unfortunately, just because a system looks correct doesn’t mean that it is. This is why we make sure to test installations to make sure they function as intended. Do all those weird intersections of storefronts or curtain wall systems with brick façade worry you? It concerns us. Fortunately, we’re able to test the installed systems per Industry Standards (AAMA, ASTM) to ensure they operate as designed. More importantly, it will prevent moisture infiltration problems from occurring in the future.
