No Good Deed Goes Unpunished…

Mold under cabinets in apartments found during one of Liberty’s investigations. What do you think caused this micro-climate that caused this growth?Even though many buildings may not be Green driven anymore, owners are still seeking higher performing buildings. Yet designs and material meant for high performance can have hidden risks.  For instance, an owner of a multi-family complex experienced unintended moisture and mold problems due to a combination of fire rating between floors and increased reduction of sound transmission between units (walls and floors). Contractors used Gyp-crete and underlayment within the floor systems which provided an increase in thickness to […]

PTAC Moisture & Mold Problems: 3 Myths That Cause Them to Fail in Warm and Humid Climates

By J. David Odom, Richard Scott, AIA, and Norman Nelson, PE

In the mid-1980s the hospitality industry developed some of the earliest niche hotel prototypes catering to the needs of the business traveler (such as Marriott Courtyards). A number of these hotels quickly began to suffer moisture, mold, and odor problems during their first one or two summer seasons. These problems were especially pronounced in the Southeast US. Presently, the hospitality industry is embracing similar minimalist style prototypes aimed at attracting millennials.  Avoiding similar problems from several decades ago are both a competitive business opportunity as well as a risk management […]

Stucco Myth #3: Direct-applied stucco is easily packed out to meet a finished plane.

In our work as forensic architects and engineers, we are regularly involved in litigation over stucco failures, including hotels and high-rise condo complexes. (For this article, ‘stucco’ refers to traditional portland cement plaster direct-applied to a masonry substrate, rather than using lath.)

Myths abound around stucco cracking. In truth, it is not abnormal to have some cracking with stucco, much of which can be relatively harmless. The key is paying attention to the types of cracks, and minimizing any significant issues that might lead to actual failure, including debonding, water intrusion, and mold problems. It is not a good idea to […]
