This topic was initially presented at the 2020 BES. 

This presentation will provide a case study of a medical research/office facility that, at nearly 35 years old, needed major exterior repairs. This mid-1980s building was constructed with thought given to energy conservation and durability by using continuous thermal insulation in the wall assembly and a durable masonry cladding system. Unfortunately, defects in the original design and construction created an exterior wall assembly that developed cracks in the exterior masonry and deterioration of the supporting steel members, and the building lacked an air barrier and leaked air badly, defeating the original energy conservation considerations. The lack of vertical masonry control joints led to widespread cracking and corrosion of supporting steel relief angles. The assessment of the masonry defects discovered that the wall assemblies lacked a weather barrier and an air barrier. Large air leaks were discovered during the cladding assessment, creating another challenge in developing restoration concepts.

The assessment resulted in three options. All steps—from the initial assessment of the building through the various design concepts and options—will review the construction challenges for the new lightweight metal panel over-cladding system, designed with a modern appearance to align with the owner’s corporate image and to coordinate with other research facilities.

The tiered approach to failures in this presentation helps clarify and provide an avenue for keeping important elements in design for long-term value of a building.
