This is a residential (Class 2 | Cat 3) soft clog fill-up water loss. The condo's plumbing backed up to the extent that several condos were affected simultaneously. The policyholder was not in town at the time of the loss, as such, the Category 3 water had several days to take root and microbial growth was prolific, especially under the kitchen cabinets. This Insight Sheet seeks to illustrate the activities that relate closely to the deployment, set-up, and breakdown of a single negative air scrubber. We also intend to explore the nuances associated with the concessions required to accommodate the fact that other condo residences reside within close proximity to the affected unit. This Insight Sheet exists to clarify how one might invoice for a negative air machine with lay flat ducting. This does not seek to include or make concessions for all equipment and/or activities as it relates to a loss of this nature.
