What SIIS does

SIIS (Società Italiana di Ingegneria e Servizi), trading as SIIS Engineering & Management, is a privately held Italian civil engineering and project management firm founded in 1996 in Padova. The company delivers an integrated, end-to-end service stack across the construction lifecycle, including project management, contract and construction process management, architectural design and engineering, site safety coordination, cost and quality control, and accredited project validation. It employs roughly 20 multidisciplinary professionals — architects, engineers, project managers, surveyors, and safety specialists — and operates domestically across Italian regions including Veneto, Lombardy, Friuli-Venezia Giulia, and Abruzzo.

The company's technical backbone is a Building Information Modeling (BIM) methodology that supports federated models, quantity takeoffs, interference checks, energy and seismic simulations, and construction phasing, complemented by tools such as Primus, Project, and Revit. SIIS is accredited by Accredia as an Inspection Body type EA 34 under UNI CEI EN ISO/IEC 17020 (RT-21) for independent project validation, a credential that anchors its regulatory positioning for compliance-critical work. Additional compliance posture is evidenced by ISO 9001:2015, ISO 45001, and UNI/PdR 125:2022 gender equality certifications.

Commercially, SIIS is a B2B professional services firm selling project-based engagements to enterprise clients — major real estate developers (Covivio), retail chains (OVS, COIN, Esselunga), industrial and manufacturing groups (Luxottica), hospitality operators (Le Sereno, Meininger), financial institutions, and educational organizations (ICS Milan International School). Revenue is generated through fee-for-service engagements sized to scope, complexity, and duration; pricing is project-specific and not publicly disclosed. Go-to-market is sales-led, relying on direct business development, referrals, and reputational credibility built over 25+ years, including notable deliveries such as Symbiosis Business District, The Sign Milano (LEED Platinum, Top 8 LEED projects in Europe), and San Clemente Palace Venice.
