I've watched videos like this where there's this big push for making modular parts where "the pieces are just like legos" and "construction needs to be more like manufacturing". And then the video shows a bunch of construction workers using fairly typical techniques. Yeah, you can position it to make things more optimal and whatever, but I still see people doing the same kind of things. The main difference I see is where they're doing it.<p>When I hear about modular construction my expectation is that you take those modules down to the sub-building or even sub-room layer. Take a floor piece, add four wall pieces, add a ceiling piece and you're essentially done. Outlets, wiring, HVAC, and even lighting are just built into those pieces and hooked up at the corners or edges.<p>I assume that this isn't the way because of the nature of timber to flex and twist as it dries, making every single structure (including these modular ones) a collection of bespoke pieces. Is there someone with more knowledge that can corroborate this?
