Testing labs in Jubail Industrial City

Ayed Eid Al Osaimi Engineering Consulting Office (OEO) is a 100% Saudi-owned independent geotechnical and materials testing engineering firm headquartered in Al Khobar, Eastern Province, Saudi Arabia. Founded in 1973 by Dr. Ayed Eid Al Osaimi, OEO has grown over more than five decades into one of the Kingdom's leading providers of geotechnical investigation, construction materials testing, and engineering consultancy services. The firm serves major industrial clients across Saudi Arabia's oil and gas, petrochemical, utilities, construction, and infrastructure sectors, including marquee names such as Saudi Aramco, Saudi Electricity Company (SEC), SABIC, the Royal Commission for Jubail and Yanbu, and SWCC. OEO's geotechnical investigation capabilities span both onshore and offshore environments, covering site investigation, soil sampling, borehole drilling, in-situ testing, and pile integrity and load testing. The firm's geotechnical teams conduct sub-surface investigations to determine soil consistency, bearing capacity, and foundation suitability for large-scale industrial and infrastructure projects. Onshore and offshore drilling rigs enable the firm to operate in Saudi Arabia's demanding desert, coastal, and marine environments, while geophysical survey methods provide non-invasive subsurface characterization. These investigations are conducted in compliance with internationally recognized standards including Saudi Aramco's geotechnical engineering procedure SAEP-383. At the core of OEO's laboratory services is comprehensive construction materials testing encompassing fresh and hardened concrete, soils, cement, asphalt (bituminous mixtures), aggregates, water, and steel. Physical, mechanical, and chemical analyses are performed on these materials to verify compliance with project specifications and international standards such as ASTM and BS. Concrete testing covers workability, compressive strength, durability parameters, and mix design verification; aggregate testing addresses grading, shape, and abrasion resistance; cement testing evaluates setting time, fineness, and strength development. The laboratory's steel analysis services include physical and chemical characterization of structural and reinforcing steel products, covering elemental composition and mechanical properties. Beyond traditional construction materials, OEO's laboratory is equipped to conduct chemical analysis, environmental testing, and microbiological testing. Water quality analysis supports construction dewatering assessments, potable water compliance checks, and industrial effluent characterization. Environmental testing capabilities address contaminant screening in soils and water matrices, supporting site remediation, baseline environmental studies, and regulatory compliance for project developers across Saudi Arabia's industrial and urban development zones. Microbiological testing of water and related samples is also performed, broadening the laboratory's scope for clients working on utilities, industrial hygiene, and environmental management programs. OEO provides non-destructive testing (NDT) services, enabling structural assessment of existing components and assets without causing damage — a critical capability for the inspection and maintenance of industrial plant and infrastructure in the Kingdom's aging petrochemical and utility estate. Calibration services for testing instruments and measurement equipment ensure metrological traceability of laboratory results to international reference standards. Geophysical surveys and land surveying extend the firm's capabilities beyond laboratory analysis to field investigation and mapping, delivering integrated site characterization packages to engineering and construction clients. OEO holds ISO/IEC 17025 accreditation, the international benchmark for the technical competence of testing and calibration laboratories, awarded by an accreditation body recognized in the United States. The firm is also certified to ISO 9001 for its quality management system. OEO demonstrates ongoing commitment to result reliability by participating in inter-laboratory proficiency testing programs organized by internationally recognized agencies including CCRL (Cement and Concrete Reference Laboratory), AMRL (AASHTO Materials Reference Laboratory), DAC, and FAPAS. These external round-robin programs benchmark the laboratory's performance against global peers and reinforce the credibility of results delivered to clients in high-stakes industrial environments. OEO operates an extensive network of offices and laboratories across Saudi Arabia, with its main laboratory and head office in Al Khobar and branch locations in Jubail, Jeddah, Riyadh, Yanbu, Haradh, Safaniya, Rabigh, Jizan, and the NEOM mega-project development zone. This geographic distribution enables responsive on-site field services and laboratory analysis across all of the Kingdom's major industrial and development corridors — from the Eastern Province energy hub to the Red Sea coast and the southern Jizan economic city. With over five decades of continuous operation, an accredited laboratory, and a blue-chip client roster spanning Saudi Arabia's most prominent public and private-sector organizations, OEO is a well-established and credible testing and investigation partner for construction, petrochemical, and infrastructure projects of any scale.
