Whether field or shop fabricated, one quality control measure to confirm the integrity and consistency of the structural sealant application is to deglaze representative assemblies—deglazing representative assemblies also assists in developing protocols for infill replacement should the infill be damaged in-service.

Prior to the adoption of the 2015 International Building Code (IBC), vents were required in the roof assembly to allow the “attic” space—between the underside of the roof deck and the top of the ceiling below—to vent to the exterior. However, the volume of air movement provided by these...

When through-wall flashing is not properly detailed or installed in cavity wall construction, the water penetration resistance of the enclosure can be compromised. This was recently observed at a multi-story office building in the southeastern U.S., that regularly experienced water leakage during prolonged rain events above ribbon window assemblies.

In the absence of a large-scale fire catastrophe, a sense of complacency may be influencing the specification of firestopping materials. In recent years, North America has seen a trend of pre-insulated back pans coming from overseas which contain foreign mineral wool that has not been tested to ASTM E2307....

A close-range examination revealed the gaskets were not driven to the required depth within the joints to engage the locking barb with the corresponding raceway in the outboard aluminum trim. Instead, they were retained in the joint through compression alone, leaving them susceptible to disengagement over time.

PT tendons are susceptible to corrosion from water and chloride (salt) ingress in similar ways as conventional reinforcing steel. However, unlike conventionally reinforced concrete, the effects of corrosion can result in the tendons losing tension and the concrete losing pre-compression.
