Commercial buildings often have additional steps and considerations, compared to a residential building. This photo illustrates a large warehouse, with a high ceiling and a significant amount of contents.
The contents need to be inspected for water damage, assessed to determine if they can be dried, relocated to prevent further damage and monitored while they are drying (so they don't become too dry and cause damage). Other contents that are deemed to not be restorable, require a thorough inventory and disposal.
High ceilings in a commercial building also present specific concerns. Large commercial equipment, scissor lifts, forklifts and scaffolding, are common practices to reach high ceiling to remove wet insulation, drop ceilings and install drying equipment to reach wet materials.
