> Crews would go to a house, perform their required task (using material that had been pre-delivered), then move on to the next house. Within the crew, work was further specialized: on the washing machine installation crew, William Levitt noted that “one man did nothing but fix bolts into the floor, another followed to attach the machine,” and so on. By breaking down the process into repetitive, well-defined steps, workers didn’t have to spend time figuring out what they should do Having worked over the years on multiple tract-home projects doing labor, framing, stacking (installing the prefab truss packages), and layout (snapping lines on slabs marking out where everything goes) I can affirm that this IS how its done with variance per-project and usually with several floorplans to scratch that "novelty" itch for buyers. The homes go up fast with each crew sweeping through a few units at a time doing their respective parts. It's efficient that way. > keeping construction on track meant a steady, uninterrupted stream of material that arrived at the jobsite exactly when needed. A lot of the materials (especially lumber) are queued up ahead of each project starting to ensure that daily flow happens. On jobs I worked on as labor my job was to hand deliver any lumber resupply requests that were below some efficiency threshold for using the heavy off road forklift -- if memory serves me correctly, 20 pieces. The windows and trusses were all pre-fabricated and delivered in bundled packages for each floorplan.
