EQUIDAS Consulting Engineers

What EQUIDAS Consulting Engineers does

EQUIDAS Consulting Engineers is a privately held consulting engineering firm headquartered at 10 Zaimi, Athens (Greece), founded in 2012 by Christos Giarlelis and Evlalia Lamprinou. Its full name — Earthquake Innovative Design & Analysis Solutions — captures the firm's mandate: seismic design of structures spanning conceptual study through detailed design and construction supervision. The firm operates as a specialized boutique with 11–50 staff, supported on demand by consultant geotechnical experts and technical draftsmen, and has remained independent with no external funding, parent company, or M&A activity since incorporation.

The service portfolio covers seismic design of new structures, seismic vulnerability assessment, seismic rehabilitation and strengthening, dynamic soil-structure interaction (SSI) analysis, machine foundation design, conceptual and detailed design, technical specification and tender documentation, construction supervision, and peer review. Technical differentiation rests on advanced analysis techniques — non-linear time history analysis using selected earthquake records, seismic isolation design (notably a 323 friction pendulum isolator system for the Stavros Niarchos Foundation Cultural Center), passive energy dissipation systems, and SSI modeling — executed on state-of-the-art structural and geotechnical software with BIM processes. EQUIDAS also conducts earthquake reconnaissance reporting.

The business model is project-based professional services revenue, with no publicly disclosed pricing. GTM is direct enterprise field sales: competitive tender for Greek public-sector work (e.g., the School Building Authority on Cephalonia and Samos), and direct commissioning from architects, developers, and nonprofit or cultural-heritage clients for private projects. Customer mix spans residential and hospitality, educational and medical facilities, cultural heritage and monuments, transportation infrastructure, and industrial and power plants. Marketing is built on academic credibility — international conference participation, peer-reviewed publications, and contributions to IABSE and FIB technical documents — rather than paid channels.
