What ETETH does

ETETH (E.T.E.Θ. Μονοπρόσωπη A.E. — Εταιρεία Τεχνικών Έργων Θεσσαλονίκης, or Thessaloniki Technical Works Company Single-Member S.A.) is a Greek general construction contractor founded in 1961 and headquartered at 6th km Thessaloniki–Thermi Road, Thermi, Thessaloniki. The company has operated as a wholly-owned subsidiary of the AVAX Group (Όμιλος ΑΒΑΞ, formerly J&P ΑΒΑΞ) since 2001. ETETH holds the highest-tier 6th Class General public works license in Greece, qualifying it to bid on and execute construction projects across all categories, types, and natures.

The company's core delivery capability spans seven verticals: infrastructure projects (highways, roads, airports, ports, bridges — including Egnatia Odos sections), building projects (municipal buildings, museums, educational facilities — including the Thessaloniki City Hall and the New Archaeological Museum of Patras), hospital and healthcare facilities, hydraulic and water engineering works (including the Valsamioti Dam), energy infrastructure (natural gas pipelines, distribution networks), railway construction, and Olympic venue construction and maintenance. ETETH deploys Building Information Modelling (BIM) as Lead Appointed Party under ISO 19650-2:2018 (certified by TÜV NORD) and maintains ten certified management systems spanning ISO 9001, 14001, 45001, 50001, 27001, 27701, 39001, 22301, 37001, and ELOT 1439. Projects are executed either independently or through consortium (Κ/Ξ) joint ventures with peer contractors.

ETETH's business model is enterprise/government (B2G): revenue is earned through participation in competitive public tenders issued by Greek ministries, regional authorities, municipalities, and public corporations, with contract values awarded through formal procurement. The company does not publicly disclose pricing; contracts are one-time, project-based, milestone-billed engagements. ETETH's primary customer is the Greek public sector, with secondary exposure to select private and municipal clients. The parent AVAX Group reported consolidated 2025 revenue of €958.2M; standalone ETETH revenue is not disclosed. Geographic scope is domestic Greece only, with no international project footprint identified.
