Staging a Construction Project for Multiple Labor Cycles
Setting up scaffolding for the duration of the job saves time on high-performance wall assemblies
We own our scaffolding because we build with exterior insulation—and this adds several labor cycles before we get to the siding. Our air barrier is the exterior plywood with either the seams taped (like on the roof) or an adhesive WRB (like we used on the walls). Adding the exterior insulation adds several more labor cycles: first there’s one for the exterior custom window flashing (“jamb extensions”). Then there are two more for the two layers of staggered insulation. On our house we added a secondary WRB over the insulation so that was another pass around the house. For the areas with cedar siding we had rain screen battens to install, siding to put up, and then a last pass to stain the cedar. For the facades with metal cladding, the standing seam metal when directly over the secondary WRB.
