Mid-afternoon on day two of virtual kindergarten last year, the teacher asked my granddaughter, “Do you want to stop now?” She replied, “Yes, and I want to stop for tomorrow, too.” Sometimes, I think general contractors on my projects have this same approach to “temporary conditioning” of the building environment during construction. They push costs to subcontractors or avoid conditioning the building under construction as long and as far out as possible. Maybe the low-bid contractor is the one that excluded the biggest portion of this cost. Maybe we should find a better way to plan and account for the costs of temporary conditioning for the building environment during construction.
