85827Y1399-Leveraging Ground-Scanning Technology to Build Understanding of Underground Infrastructure in New York City

The City of New York is issuing an RFI to gather information on the feasibility of deploying ground‑scanning technologies across the five boroughs to create a comprehensive 3‑D map of underground infrastructure for the 3DU program. Respondents are asked to outline technology options, data‑processing workflows, integration methods with existing utility records, limitations of the methods, and any complementary non‑invasive techniques. The response must be submitted as a single PDF (or via PASSPort) by 11 PM on 16 Nov 2026. • Identify suitable ground‑scanning methods (e.g., LiDAR, GPR, seismic) for NYC’s varied geologic conditions and dense built environment. • Detail data‑collection, processing, and deliverable formats, including turnaround times and quality‑control procedures. • Explain how the proposed data will integrate with existing utility GIS layers to improve asset visibility and support the 3D Underground platform. • Highlight any technology limitations, non‑invasive alternatives, and provide additional observations or recommendations.
