SEQUAS

What SEQUAS does

SEQUAS (legal name: SEQUAS Ingegneria S.r.l. Società Benefit) is a privately held Italian engineering consultancy headquartered in Rome with a secondary office in Turin, founded in 2002 and operating as a Società Benefit (Benefit Corporation). The firm functions as a center of competencies providing integrated technical, normative, and procedural engineering consulting to public and private clients across Italy, with approximately 30 professionals delivering six interconnected service lines: Progettazione (integrated architectural and plant engineering design), DL/CSE (construction site management and safety coordination), Sostenibilità (sustainability certification consulting for LEED, BREEAM, WELL, and other protocols), Ambiente (environmental remediation with deep specialization in downstream petroleum and fuel distribution), Energia (energy efficiency, renewable energy design, and EPC delivery), and HSEQ (health, safety, environment, and quality management systems). The firm serves a client base spanning Italian government and SOEs (RFI, Aeroporti di Roma, Sogin, Regione Lazio, Roma Capitale, CONI, Aeronautica Militare), major private enterprises (Ferrero, Poste Italiane, Plenitude, Museo Egizio, RAI, BNL), and real estate/industrial clients.

The firm's technical backbone is built on BIM (Building Information Modeling) methodology compliant with ISO 19650 and UNI 11337 standards, complemented by dynamic energy modeling using EnergyPlus, Life Cycle Assessment (LCA) for environmental impact evaluation, Building Performance Simulation (BPS), and ENAC-licensed drone-based surveying for site assessment. These capabilities support integrated delivery from preliminary design through construction management, with particular depth in cultural heritage projects (Museo Egizio, Scuderie del Quirinale, Cisterna Sette Sale) and energy retrofit (Superbonus 110% residential complex in Via della Magliana). The firm holds ISO 14001 and ISO 9001 integrated management system certifications, ESCo certification per UNI 11352, and team members hold domain credentials (LEED AP BD+C, BREEAM AP, WELL AP, EGE).

The business model is professional services on a project-by-project basis with custom scoping and multi-year contract cadences. Revenue is generated through direct professional service contracts with enterprise and government clients, public procurement tenders, and through the Engeko consortium (formed 2015), a stable consortium of 10 specialized engineering companies providing access to large-scale infrastructure projects. Pricing is not publicly disclosed and varies by project scope, complexity, and client type. The firm operates exclusively in Italy through direct engagement with no intermediary distribution layers, and maintains professional association memberships in AICARR, FIRE, and GBC Italia for industry visibility.
