The effects of corrosion on metal building components range from aesthetically undesirable appearances to hazardous structural conditions. This is particularly the case for masonry buildings constructed in the early 1900s, where unprotected structural steel is often in contact with exterior wall construction.

On a building constructed in 1929 with exterior loadbearing masonry walls, modifications were made to loadbearing masonry demising walls during past renovation efforts. A recent investigation has revealed these modifications present a serious structural stability problem for the building.

Site planting is an important part of most construction projects. When done correctly, planting can add the final touch to a project. Plants may be valued for their aesthetics, but they are living things, and have specific requirements, including nutrition, water, and sun. Failure to meet these basic requirements...

Two nearly identical domes constructed in different climate zones provide an opportunity to evaluate the ways in which environment and weather affect service life and performance of construction materials. One of the domes is located in the Southeast, in a hot, humid climate, and the other is located in...

Exterior steel elements—both structural (e.g. columns) and architectural (e.g. handrails)—need to be protected from corrosion, usually with high-performance coatings. However, even high-performance coatings degrade when exposed to severe environments.

Insulating glass units (IGUs) are often used in window and curtain wall assemblies due to their improved thermal performance as compared to assemblies with monolithic glass infill. However, monolithic glass can function for the life of the building (barring breakage), while IGUs can fail over time.

Occupants of a recently completed building reported localized peeling of wallcoverings from partition walls (primarily coinciding with the brick cladding/exterior curtain wall interface), as well as condensation on many interior surfaces during the cooling season.
