Second Avenue Subway – BIM Context

City-defining infrastructure. Complex urban environment requiring sophisticated coordination. Budget $3.4B Phase 1, $3.4B Phase 2. Likely BIM applications based on project type: 3D underground alignment modeling, tunnel boring path coordination, station architectural/MEP/structural coordination, utilities conflict detection with dense existing infrastructure, geotechnical modeling, systems integration (signals, communications, traction power), construction sequencing maintain adjacent operations, as-built documentation integration existing subway systems. Project requires maintaining 100% service adjacent lines during construction. Advanced digital tools essential coordination dense urban underground environment. Total ~$6.8B investment Phases 1-2.
