Where do you store hundreds of running feet of prefabricated wall during construction delays?
How do you move sections of prefabricated wall into and within a dryed-in building?
How do you trim a section to fit and extend another when construction is not ideal?
Who is responsible when something is not right?
And of course there’s getting UL listings for any proprietary electrical connections and issues of inspection for code compliance.
Prefabricated walls are common and are suitable for cubical farms. They tend to cost more psf than regular construction but can be depreciated as furniture and reconfigured more easily than site built walls and fixtures.
