Lithos Consulting Engineers

What Lithos Consulting Engineers does

Lithos Consulting Engineers is a privately held, founder-owned structural engineering consultancy headquartered in Vari, Greece. Founded in 2000 by co-CEOs Nick S. Zygouris (PhD in seismic design of reinforced concrete, former President of the Association of Civil Engineers of Greece) and Irene Bandeka (NTUA-trained structural engineer), the firm delivers full-lifecycle civil engineering services — from inception through design, construction, and post-construction — to both government/public sector and private enterprise clients. The firm's six service lines are Advanced Structural Design, Structural Assessment & Upgrading of Existing Structures (its signature niche using EC8-3 regulations), Quality Control of Materials, Consulting on Special Issues, Project & Design Management, and Research & Development.

The company leverages deep codified expertise in European seismic regulations and modern structural codes to differentiate in a specialized niche: the assessment, strengthening, and repair of existing reinforced concrete buildings. Its technology stack consists of industry-standard civil/structural engineering software and BIM tools, supplemented by in-house C++ development capability. The firm holds ISO 9001:2008 certification and operates with approximately 7 staff.

Lithos runs a project-based professional services model with quote-driven pricing and direct client engagement — no intermediaries or channel partners. Its public project portfolio is anchored by large Greek enterprises such as TERNA S.A. (Crete-Peloponnese undersea power interconnection), INTRAKAT S.A. (New International Airport at Mytilene), Drago Boats, Vlahos Bros SA, and PAKO SA, spanning airports, industrial facilities, commercial buildings, and energy infrastructure — exclusively within Greece.

• Ramboll: International engineering, design, and consulting firm with significant structural engineering practice across buildings and infrastructure. Competitor for larger Greek and pan-European structural design commissions.
• Egis: French-headquartered engineering and consulting firm active in transport, energy, buildings, and urban development across Europe, including Greece. Provides overlapping structural and infrastructure engineering services to public and private clients in Lithos's addressable market.
• Sweco: European engineering, design, and environmental consultancy with structural engineering services across infrastructure and buildings. Operates across Northern Europe and competes for EU-funded infrastructure work adjacent to Lithos's Greek territory.
