In Construction Management during 1966-1992, the period is characterized by the maturation of decision-support and planning through computational tools. The late 1980s introduced AI-driven planning with expert systems and knowledge-based planners that could generate project networks and schedules, while resource-constrained scheduling advanced through bounded enumeration, heuristics, and synthesis of historical data. Computerization efforts began addressing fragmentation in the AEC industry by enabling integrated data flows among design, planning, and field operations, laying the groundwork for more integrated project delivery.
