The preconstruction phase commonly presents challenges, including uncertain site conditions, budget constraints, scheduling delays due to permitting or design changes, complexities in obtaining necessary permits, contractor selection, risk management, stakeholder coordination, value engineering decisions, environmental compliance, change management, market fluctuations, client expectations, resource allocation, quality assurance, conflict resolution, and the adoption of construction technology. These challenges require proactive planning, effective communication, and experienced project management to help ensure a successful transition from planning to construction.
