The emergence of modular construction as an option for new construction is becoming mainstream. While the reasons why have been reported on extensively, what has not been reported is that the modular construction industry has been plagued by mold and moisture problems, especially on projects located in warm and humid climates like the Southeast U.S. Both wood-frame and steel-frame modular construction units have experienced condensation problems in crawl spaces, within marriage walls, and within ceiling-to-floor cavities that have not only resulted in deterioration of the wood and corrosion of metal floor pans, but have also led to damaged wallboard and mold issues.
The greatest risk of modular construction failure has been seen in facilities that are domicidal or multi-family in nature, such as hotels, student housing, senior living, and soldier housing. The living units of these types of facilities have inherent similarities: they require both an individual cooling/heating unit, bathroom exhaust, and some sort of central HVAC make-up air system. In addition, these kinds of buildings contain many more modular “boxes,” increasing the number of marriage wall interior cavities and ceiling-to-floor cavities that might not be required in other types of modular construction.
