You have run hundreds of houses. Then a 60,000 square foot facility floods, the building
has its own air handling logic, the electrical service will not carry what you need to plug
in, and the property manager wants a drying plan with numbers in it before anyone mobilizes.
Nothing about that job is a bigger version of a basement. The structure behaves differently,
the psychrometrics are less forgiving, the equipment is heavier and needs to be sized rather
than guessed, and documentation is the deliverable the client actually reads.
That is the gap Catalyst Training exists to close — with certification training built on
the ANSI/IICRC S500 standard, and with per-project consulting for the jobs you are bidding
or running right now.
