What SIIP does

SIIP (legal name: S.I.I.P. srl) is a privately held Italian engineering consultancy headquartered in Naples (Via Toledo, 156, 80134 Napoli), founded in 2011 and operating with 11–50 employees. The firm specializes in integrated engineering design for complex technological infrastructure projects, with particular emphasis on underground works, railway systems, and metro stations. Its core technical methodology is BIM (Building Information Modeling), used to coordinate multiple disciplines — civil works, mechanical systems (HVAC, plumbing, fire protection), electrical systems, telecommunications, video surveillance, and security installations — within a unified digital model that supports real-time design modifications and cross-discipline coordination.

The company delivers its services exclusively to Italian public-sector clients through participation in public procurement tenders. Its service portfolio spans four core areas: BIM-based integrated design, railway and metro infrastructure engineering, construction supervision and RUP (Responsabile Unico del Procedimento) support, and a newer railway-authorization procedures practice targeting ANSF oversight of isolated railway lines. Notable project references include metro stations and lines in Naples (Line 6, Circumvesuviana, Metro Campania Nord Est, Montesanto station of Sepsa). The firm maintains nine third-party certifications — ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, SA 8000:2014, ISO 30415:2021, ISO 27001:2022, ISO 13485:202, UNI PdR 74/2019, and UNI PdR 125/2022 — covering quality, environmental, occupational health, social accountability, diversity and inclusion, information security, medical devices, and gender equality. Ownership is concentrated under Enrico Franco as Socio Unico (sole shareholder) and Amministratore, with multiple Franco family members in key operational roles and Giuseppe Allegretti serving as Coordinatore Generale e Direttore Tecnico.

Direct peers

• Proger: Italian engineering and project management consultancy with an established rail, metro and public-infrastructure practice across integrated design and works supervision. Closely comparable in service mix and Italian public-sector client base.
• RINA: Italian-headquartered engineering services and certification group with a dedicated infrastructure and transport practice covering rail, metro and complex public works. Comparable on multi-disciplinary engineering design and Italian public-sector delivery.
• Italferr: State-owned Italian railway engineering subsidiary of Ferrovie dello Stato Italiane, specializing in design and supervision of rail and metro infrastructure. Direct competitor for the same public-procurement tenders that constitute SIIP's core market.
• Systra: France-based engineering firm specialized in rail and public transport, with active Italian operations. Directly competes for metro and railway design mandates using comparable BIM-integrated multi-discipline capabilities.

Broad incumbents

• Mott MacDonald: Global engineering consultancy with a strong rail, metro and tunnel design practice serving public-sector clients worldwide. Comparable in multi-discipline integrated design but at much larger scale.
• WSP: Global professional services firm with a major rail and transit design practice, including underground works. Comparable service offering to SIIP but delivered at enterprise scale across multiple geographies.
• AtkinsRéalis: Global engineering services firm (formerly SNC-Lavalin) with a large rail and transit design practice. Competes in the same tender universe but operates at significantly greater scale and broader geographic scope.
• Arup: Global engineering firm with deep rail, metro and underground infrastructure capabilities, including integrated BIM-based design. Overlaps with SIIP's service portfolio but operates across a vastly broader infrastructure portfolio.
