The California public-building pipeline is unusually early-stage: 225 of 390 active projects (58%) have not reached a bid board yet. Demand here is fragmented. 243 public buyers across 7 counties account for the 405 tracked projects, and the largest of them (Cal Poly Pomona) carries just 8. The buyer mix splits mainly between school districts (38%) and municipal governments (15%). Within the pre-bid pipeline, 95 projects are in design right now, which is typically when owners pick design partners and lock program scope.
