AOSA

What AOSA does

AOSA S.A. is an Argentine professional services firm specializing in geotechnical engineering for the built environment. Founded in 1970 as Laboratorio de Ingeniería Triaxis SRL and rebranded to its current form in 2013, the company operates from a single headquarters and laboratory facility in Ciudad Autónoma de Buenos Aires (Humberto Primo 722) with a team of approximately 12 employees. It is privately held, family-influenced, and holds no public listing or external funding.

The company's offering is organized around four integrated service lines: (1) laboratory testing of soils and rocks following ASTM standards (including USCS/AASHTO classification, Proctor/CBR compaction, oedometer consolidation, triaxial UU/CIUC/CIDC, UCS, permeability, and chemical analyses); (2) field testing and in-situ measurement (SPT, CPTu, PMT, VST, plate load tests, Lugeon/Lefranc permeability, pile integrity testing, and Cross Hole); (3) applied geophysics using non-destructive techniques (refraction seismic, SASW/MASW, electrical tomography, GPR, Cross Hole/Down Hole); and (4) geotechnical instrumentation delivered through the AOSA-GIOT-INSUS unified working group for bridges, shoring, embedded sensors, mining, and tunneling. Quality management is aligned with ISO 9001-2015 and proficiency is validated through international inter-laboratory rounds with PTA (Australia).

AOSA monetizes these capabilities on a project-based, quote-driven professional services model. Clients are enterprise and government entities across real estate development, industrial, mining (including lithium and gold), oil & gas, energy/power generation, transportation infrastructure, and water/sanitation sectors in Argentina, with isolated international work in Paraguay. Notable repeat clients include Techint, Siemens, Pan American Energy, YPF/AESA, SRK Consulting, Knight Piesold, Consultatio, AySA, and Benito Roggio. Go-to-market is direct enterprise sales supported by a structured web-based project inquiry form and a LinkedIn presence; the company has completed more than 3,500 geotechnical studies over its history and is a member of SAIG and ISSMGE. Revenue is not publicly disclosed.

Core offering

AOSA S.A. delivers integrated geotechnical investigation and engineering services to enterprise clients, encompassing laboratory testing of soils and rocks, in-situ field testing, non-destructive applied geophysics, and geotechnical instrumentation for monitoring. Services support foundation design, ground characterization, quality control, and structural monitoring for construction, infrastructure, mining, oil & gas, and energy projects. Engagements are project-based, scoped via custom quotations derived from detailed client project inquiries.

Product overview

AOSA is a geotechnical services company offering an integrated portfolio of four core service lines: Laboratory Testing Services (physical, chemical, mechanical, and hydraulic analysis of soils and rocks), Field Testing Services (in-situ testing including SPT, CPTu, and pile integrity testing), Applied Geophysics Services (non-destructive terrain characterization using seismic, electrical, and electromagnetic methods), and Geotechnical Instrumentation Services (monitoring and sensor installation for construction and mining projects). These services work together to provide comprehensive geotechnical studies from site investigation through construction monitoring.

Products and services

• Laboratory Testing Services Physical, chemical, mechanical, and hydraulic characterization of soils and rocks following ASTM standards, including USCS/AASHTO classification, unit weights, moisture content, granulometry, hydrometry, X-ray diffraction, scanning electron microscopy, thermal conductivity, Proctor/CBR compaction, oedometer (consolidation, expansion, collapse) tests, triaxial tests (UU, CIUC, CIDC), UCS, point load, slake tests, permeability (constant and variable head), Pin Hole tests, and chemical analyses (Cl-, SO42-, pH, MO, salts, BTEX, DRO, GRO, heavy metals). Used by enterprise clients in real estate, industrial, mining, and energy sectors requiring soil and rock characterization for foundation and earthworks design.
• Field Testing Services Direct sampling and measurement in the field for geotechnical profile characterization or execution controls, including SPT, CPTu, PMT, VST, dynamic tests (DPL, DPH, DPSH), plate load tests (PLT), in-situ density tests, low-disturbance sampling (Denison, Shelby, Fixed Piston), pump tests at scale, Lugeon and Lefranc permeability, pile integrity testing (PIT), static and pseudo-static pile testing, Cross Hole in piles and walls, and parallel seismic in structures. Used by enterprise clients requiring in-situ verification of subsurface conditions and execution quality control.
• Applied Geophysics Services Dynamic, electrical, and electromagnetic characterization of terrain through non-destructive techniques for geotechnical purposes, including refraction seismic, 1D spectral analysis (SASW), 2D multi-analysis spectral and tomography (MASW), 1D vertical electrical soundings, 2D electrical tomography with 24 electrodes, Cross Hole/Down Hole, and ground-penetrating radar (GPR). Used by enterprise clients needing non-destructive subsurface imaging for site investigation in congested or sensitive project environments.
• Geotechnical Instrumentation Services Geotechnical instrumentation services delivered through the unified working group AOSA-GIOT-INSUS, including load tests on bridges and viaducts, monitoring of shoring and facades, installation of embedded sensors, mining and tunneling applications, and comprehensive technical advisory.

Regional players

• GEOSOL (Geotecnia y Suelos): Regional Argentine/Latin American geotechnical engineering firm offering soil studies, foundation design, and field testing. A direct domestic competitor operating in similar service segments and sharing the same end-client base in real estate, infrastructure, and industrial projects.

Direct peers

• ConeTec Group: Specialist geotechnical site investigation contractor offering CPTu, SPT, sampling, and laboratory testing across the Americas. Closely matches AOSA's field testing and in-situ measurement capabilities and competes directly for similar infrastructure and mining projects.
• Knight Piesold: International consulting firm specializing in geotechnical, hydrogeological, and tailings engineering for mining and energy projects. Overlaps directly with AOSA's mining and energy geotechnical offerings, particularly across Argentina, Chile, and Peru.
• SRK Consulting: Global mining and geotechnical consulting firm that performs site investigations, geotechnical characterization, and tailings assessments. Although SRK is also a client of AOSA on multiple mining projects, it provides directly overlapping geotechnical, rock mechanics, and hydrogeology services that compete for the same end mining clients in Argentina.

Emerging players

• Haley & Aldrich: US-based geotechnical and environmental engineering consultancy serving infrastructure, energy, and real estate clients. Provides overlapping subsurface investigation, foundation engineering, and environmental site assessment services comparable to AOSA's portfolio.
• Itasca International: Geotechnical and rock mechanics consulting firm known for numerical modeling software (FLAC, PFC) and specialized mining geotechnical work. Overlaps with AOSA's mining and instrumentation services, particularly in deep mining and tunneling applications.
• Geosyntec Consultants: Environmental and geotechnical engineering firm specializing in site characterization, remediation, and water resources. Competes with AOSA in environmental and industrial site assessment work, particularly for energy and infrastructure clients.

Broad incumbents

• Soletanche Bachy: Global specialty foundation contractor offering geotechnical works, deep foundations, and ground improvement. Although also a client of AOSA, Soletanche Bachy directly competes for foundation and geotechnical characterization scopes on major infrastructure and port projects.
• Fugro: Dutch-based global leader in geotechnical site investigation, geophysical surveys, and offshore site characterization. Offers a much broader portfolio than AOSA but directly competes for large infrastructure, energy, and offshore engineering projects that require integrated geotechnical services.
• Golder Associates (a WSP company): Global engineering consultancy providing geotechnical, environmental, and mining services. Now part of WSP, Golder directly competes with AOSA in mining site characterization, foundation engineering, and environmental site assessments across Latin America.
