3TI Progetti

What 3TI Progetti does

3TI Progetti S.p.A. is a Rome-headquartered, employee-owned engineering and architecture consultancy founded in 1997 by Alfredo Ingletti, Giovanni Maria Cepparotti, and Stefano Luca Possati. The firm delivers integrated multidisciplinary design, project management, and construction supervision services across three operating divisions: General Buildings, Infrastructure, and International Development. Core service lines span metro and railway design (Doha Metro Red Line South, Bucharest Metro Line 5, Agra Metro), healthcare engineering (Cluj Regional Emergency Hospital, 849 beds), roads and bridges (Motorway A7 Romania, Skurusunds Bridge Sweden), airport and port infrastructure, nuclear and fusion facilities (ITER-Cadarache), environmental engineering (Po River Renaturalization under PNRR), and sustainable building design. All projects employ BIM methodology, certified under PdR 74:2019 since the firm's full transition to BIM in 2012.

The company serves primarily public-sector and large institutional clients, including transport administrations (Trafikverket, RB Rail AS, Italian railways), ministries of health (ANDIS Romania), municipalities, and international development organizations. Customers are won through competitive tendering, design competitions, framework contracts, and JV partnerships with firms such as Tractebel, Yüksel Proje, CCCC, Pentacle, and Turner & Townsend. Revenue is generated on a project-based, multi-year professional-fee model tied to design and supervision scope; pricing is non-standard, quote-driven, and contract-by-contract. The firm operates in 70+ countries with reported 75% foreign turnover, a Dubai branch established in 2011, and a 3,000+ project portfolio since founding.

3TI is held entirely by its partners (20 partner-shareholders as of 2021) with no external institutional investors, listed status, or disclosed funding rounds. The firm is consistently ranked in the ENR Top 225 International Design Firms (since 2015), holds Chairman Alfredo Ingletti's FIDIC Presidency (effective September 2025), and maintains comprehensive certifications (ISO 9001, 14001, 37001, 45001, PAS 24000, UNI PdR 125, BIM PdR 74:2019). In 2024, 3TI co-founded the 3AS Consortium with Alcotec and Studio Speri to consolidate into a multi-firm engineering platform targeting global leadership. Strategic positioning emphasizes sustainability (ESG Committee, UN Global Compact adherence) and talent retention through the only Italian employee-ownership model of its kind.
