NYSDOT Design-Bid-Build Current Practice

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.
