What Grupa NDI does

Grupa NDI is a privately held Polish construction capital group headquartered in Sopot, founded in 1991, operating as a general contractor across infrastructure, hydrotechnical, road, rail, industrial, energy, and public utility construction. The group employs over 700 people and executes large-scale projects for both public sector clients (GDDKiA, Urząd Morski w Gdyni, municipal governments, universities) and private enterprise (Grupa ORLEN, PGZ Stocznia Wojenna). It operates through six wholly-owned subsidiaries — NDI S.A., NDI Sopot S.A., NDI Energy sp. z o.o. (energy/industrial/pipeline), NDI Development sp. z o.o. (premium real estate), NDI Facility Services sp. z o.o. (property management), and Inter Energia S.A. (electricity trading) — providing both project-based construction revenue and recurring facility management and energy trading streams. Core technical capabilities include specialized hydrotechnical engineering (port construction, shipping canals, artificial islands, quays, breakwaters), certified welding teams with UDT and Institute of Welding qualifications, an in-house Bituminous Group for asphalt work, and UDT-authorized pressure equipment and pipeline manufacturing through NDI Energy.

The company's revenue model is primarily project-based general contracting with competitive bidding for public tenders and direct negotiation for private enterprise work. Pricing is contract-specific and not publicly disclosed. Notable portfolio includes landmark projects such as the Vistula Spit Shipping Canal (with Besix N.V. consortium, ~500M PLN), the ORLEN Maritime Terminal on Martwa Wisła (500M+ PLN, 2M tons annual capacity), Terminal T5 for offshore wind (commenced April 2025), PGZ Stocznia Wojenna shipyard halls under the Miecznik defense program, the Gdańsk Shakespeare Theatre, and current ongoing works including DK91 modernization, Silesian Interdisciplinary Chemistry Centre, AGH Building S-1, and Katowice City Stadium. The company holds ISO 9001, 14001, and 45001 certifications across its operating entities and is a signatory to the Agreement for Safety in Construction. Geographic footprint is concentrated in Poland with regional offices in Sopot, Warsaw, Katowice, and Kraków, though recent positioning at the Ukraine Reconstruction Conference signals intent for cross-border expansion.
