Even electronic plans in some jurisdictions require ‘wet stamp’ and wet signature before permits are
issued. This can involve separate trips to the building department by all the licensed professionals, for a long session of stamping and signing for large sets of drawings. This is a considerable cost to the private sector, that can be eliminated by acceptance by the jurisdiction of some electronic means of seal and signature on the plans.
