Field & Laboratory Testing Services
We operate a fully equipped and professionally managed civil engineering testing laboratory delivering accurate and timely results in Soil, Concrete, Asphalt, Aggregates, and Construction Materials testing. Our field investigation services include FDT, DCP, Sand Cone, CBR, and core sampling, supported by experienced field technicians and NEOM-compliant quality procedures. Our lab adheres to international standards such as ASTM, AASHTO, BS, and ISO/IEC 17025.
Calibration & Equipment Validation
We offer traceable and highly accurate calibration and validation services to ensure your laboratory and field equipment comply with ISO/IEC 17025 and project-specific standards. Our scope includes calibration of compression machines, load frames, ovens, pressure gauges, balances, thermometers, Proctor molds, and compaction tools. We service asphalt and concrete equipment such as Marshall and gyratory compactors, ovens, and mixers; verify field devices like sand cone kits, density gauges, core drills, and thermometers; and calibrate soil and aggregate equipment including sieves, shakers, molds, and balances. All calibrations are supported by full documentation, traceable certificates, and conformity reports—ensuring equipment accuracy, reduced downtime, and continuous compliance.
Vendor Technical Assessment & Consultancy
Our engineering and quality assurance team delivers comprehensive technical audits and evaluation services to ensure compliance, reduce risk, and support informed decision-making. We conduct quality system and material compliance audits, review method statements, ITPs, and certifications, and perform factory acceptance tests (FAT) for critical materials and equipment. Our assessments cover production facilities, in-house testing capabilities, and supplier quality management systems. We also carry out vendor and subcontractor prequalification audits, identify technical gaps, and assist in corrective action planning. These services empower our clients to engage only qualified partners, optimize procurement strategies, and maintain technical excellence across all project phases.
