The processes and systems in place for designing and installing mechanical, electrical and plumbing systems have largely remained the same for decades. Sure, there have been many improvements, from CAD and Revit to press fittings, and hundreds of innovations and systemic improvements.
But at the end of the workday, the people in the field doing the demanding work of installing piping, valves, fittings, conduit, cable, siding, etc., have more or less been doing things the way they’ve always done them for years. We all know the refrain: “This is the way we’ve been doing this for years. It works, and it keeps us from getting too many callbacks and from having to deal with lawyers.”
