FIRST-EVER NYSDOT project where 3D model issued as legal contract document (awarded Spring 2020, under construction). Represents next generation pilot advancing BIM use – model becomes legal contract document vs 2D plans. Agency documenting lessons learned. Eliminates/minimizes paper plans, requires bidders use digital copy, 3D model entire project containing topography, geotechnical, roadway, bridge information. Second project model-based contract planned Spring 2021. Breakthrough: model IS the contract.

For DBB projects: NYSDOT generates designs in 3D model in-house, converts model, delivers work as 2D information. Contractors then use 2D to reconstruct necessary 3D details. Process challenging due to incomplete/inaccurate information during 2D-to-3D conversions. Recognizing need robust data management strategy facilitate seamless exchange information through digital-as-builts (DABs) during transition to digital workflows. Consequently seeking specify work using various electronic file formats potential minimize/eliminate data loss during information transfer. Past decade particularly following 2011 GIS implementation improved integration DAB processes/construction as-built data.

EARLY PILOTS: Creating accurate geometric models roadways, utilities/drainage, 3D solids some bridge elements. Intended uses: help construction activities automation tools stakeout, AMG, inspection verification, quantity measurements. LATER PILOTS: Tested capture 3D digital as-built models real time exported GIS. 2014: Kosciuszko Bridge first DB contract with BIM requirements, piloted 4D models. KEW GARDENS: Next large complex project with BIM requirements (focus case study). MODEL-BASED DELIVERY: Route 28 bridge first 3D model becomes legal contract document (Spring 2020 awarded). Second model-based planned Spring 2021. Progression: geometric modeling → as-built capture → 4D scheduling → model-as-contract.

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.

“In 10 years, we will be living in BIM world” – Cosima Crawford, Chief Engineer NYCTA (2009 statement). “It’s our new reality.” Oct 1 2009: NYCTA started all new projects using Bentley V8i platform (released Dec 2008) create bi-directional data flow among project collaborators. Only structural BIM was bidirectional during Second Avenue Subway design initially. NYCTA now demanding BIM of consultants. Tackling same challenges building sector seeing transition: BIM technology issues, process change, institutional buy-in. Contractors already onboard expecting BIM. Vision: full digital project delivery ecosystem.
