What are the methods for construction dispute resolution?

Dispute resolution hierarchy: (1) Negotiation - direct discussion between parties, lowest cost, preserves relationships, (2) Mediation - neutral facilitator helps parties reach agreement, non-binding but high success rate, (3) Dispute Review Board (DRB) - standing panel provides recommendations during construction, (4) Arbitration - binding decision by neutral arbitrator(s), faster and cheaper than litigation but limited appeal, (5) Litigation - court proceedings, formal discovery, appeals possible, most expensive and time-consuming. Contracts specify dispute resolution procedures. Early resolution preferred; multi-tiered approaches increasingly common.
