Must be spring – in the last couple of weeks I have noticed neighbors getting new sod, redoing their HVAC, their roof and their driveway. In each case I have stopped at talked to the contractors – amazingly they can do all their projects in a day or two.
Each one benefits from efficiencies at the “factories” designed to make the implementation at our homes so much more efficient than 10-30-50 years ago – from the squares the sod is cut into and the palettes they are delivered on, the dense packs the insulation comes in and expands as it is blown in, the design of the shingles to work with modern guns designed to staple them and survive hurricane strength winds, the cement designed to be mixed in small lots at our houses.
Watch the four videos below if it interests you on how sod, insulation, shingles and cement are manufactured. BTW, none of these factories are the biggest or most efficient for each product class, but I can spend hours watching such videos.
