What Geognosi does

Geognosi S.A. (ΓΕΩΓΝΩΣΗ Α.Ε.) is a Greek geotechnical engineering consulting firm founded in 1983 and headquartered in Thermi, Thessaloniki. The firm provides field investigations, laboratory testing, geotechnical design and construction supervision for public and private infrastructure projects, serving government agencies (Egnatia Odos, ERGOSE, Public Power Corporation, Athens 2004 Olympic Committee), industrial enterprises (Hellenic Petroleum, Amylum Hellas), construction companies, and international clients in Albania, Bulgaria, and Cyprus. Service lines cover borehole drilling, in-situ testing (CPT, pressuremeter, vane), laboratory analysis (triaxial, consolidation, shear, classification), foundation and retaining structure design, slope stability, ground improvement, tunnel design, and landslide remediation.

The firm operates a vertically integrated technical platform anchored by two proprietary in-house systems developed over three decades: SOILAB (a central laboratory data management and borehole log system in use since 1992) and GEOdb (a networked project management database deployed since 1998), complemented by approximately 210 internally developed specialized scientific programs and 142 commercial software licenses (PLAXIS, FLAC, PCSTABL, GEO5, Rocscience). Field operations are supported by 8 owned drilling rigs (track-mounted, truck-mounted, and a floating barge for marine investigations), penetrometers, and a fully equipped 230m² geotechnical laboratory. IT infrastructure spans 55 PCs with gigabit networking backed by 6 servers.

Geognosi generates revenue through professional services fees, with public-sector projects acquired via competitive tendering and private-sector clients engaged directly. The firm holds the highest 'E Level' certification in Greece for geotechnical engineering (Γ.Ε.Μ. registration number 232) and is ISO 9001:2015 and ISO 14001:2015 certified by TÜV, with ISO 17025 laboratory accreditation in progress. Ownership is concentrated among 13 senior partners, of whom 11 hold civil engineering degrees with postgraduate qualifications in geotechnical and geoenvironmental engineering.

Core offering

Geognosi S.A. provides professional geotechnical engineering consulting services spanning field investigations, in-situ and laboratory testing, geotechnical design, and construction supervision. Services include borehole drilling (on-shore and offshore via a floating barge), in-situ testing (CPT, pressuremeter, vane tests), laboratory analysis (triaxial, consolidation, shear, permeability, classification), and engineering design for foundations, slopes, retaining structures, tunnels, ground improvement, and landslide remediation. The firm serves both public infrastructure works and private industrial clients primarily in Greece, with selective international engagements.

Product overview

Geognosi S.A. is a geotechnical engineering consulting firm providing integrated services through three core operational systems: SOILAB (in-house laboratory data management system developed in 1992), GEOdb (in-house project management database developed in 1998), and comprehensive field/laboratory investigation services supported by proprietary equipment. The company operates approximately 8 drilling rigs and a 230m² laboratory facility. The software portfolio includes in-house developed programs (SOILAB, GEOdb, BOR-LAB, K-WATER, P4014, SETL, H-B, BEARING, LIQUE-RISK) alongside commercial geotechnical software packages (PLAXIS, FLAC, PCSTABL, GEO5, Rocscience products, Geologismiki suite) totaling around 142 commercial licenses and 40 free/developed programs.

Broad incumbents

• Arcadis: Global design and engineering consultancy with substantial geotechnical expertise in transportation, water and building projects. Overlaps on infrastructure site investigation and design but as part of a wider portfolio.
• AECOM: Global infrastructure consulting giant with substantial ground engineering practice; competes on megaprojects and EU-funded infrastructure where scale and multidisciplinary delivery are required.
• WSP Global: Global professional services firm with significant geotechnical and ground engineering capabilities (including ex-Golder). Competes on large infrastructure tenders through broader service offering and international scale.
• Stantec: North American-headquartered global engineering firm providing geotechnical, environmental and infrastructure consulting. Competes on large public infrastructure programs where geotechnical services are bundled with broader engineering scope.
• Arup: Global engineering consulting firm with a strong geotechnics practice covering investigation, foundation design, tunnels and seismic engineering. Competes on large infrastructure projects though as part of a broader multidisciplinary portfolio.

Direct peers

• Geosyntec Consultants: US-headquartered consulting firm specializing in geotechnical, geoenvironmental and water resources engineering. Directly comparable service mix (site characterization, lab testing, foundation design) for infrastructure and industrial clients.
• Golder Associates (now part of WSP): Global geotechnical, environmental and earth sciences consulting firm with deep roots in site investigation, geotechnical design and laboratory testing; a near-direct competitor in service portfolio and customer profile.
• Fugro: Dutch global leader in geotechnical, geophysical and geoscience services for infrastructure, energy and offshore markets. Most directly comparable in core offering (subsurface investigation, lab testing, geotechnical design) though operating at vastly larger scale and global footprint.

Regional players

• TEPRO Consulting Engineers S.A. Greek engineering consulting firm providing geotechnical, environmental and infrastructure design services. Competes with Geognosi in the Greek public tender market for transportation and building projects.
• EDAFOS Consulting Engineers S.A. Greek geotechnical and environmental engineering consulting firm based in Athens. Direct Greek-market competitor on public infrastructure tenders and private-sector foundation/ground improvement work.
