[Polygon’s](https://www.polygongroup.com/) [Rob Sullivan](https://www.linkedin.com/in/robert-sullivan-94289916/), aka Rob on the Job, provides a “day in the life” tour of a construction site in Allison, Maryland. As a part of his workday, Rob focuses on maintaining temperature and humidity control while installing finished material in a six-story building. Control achieved using four H.C.U.s (Hybrid Desiccate and Refrigerate Units) is particularly effective given the day’s high relative humidity of about 90% and temperature of around 67 degrees. Rob checks the gear, provides a glimpse into installing ACU 6000 CFED units, and discusses on-site safety measures. He concludes his video by thanking viewers for joining him and promising future on-the-job adventures.
