Materials Inspector

Dubai, UAE

Receiving Inspection At Site

• Inspect all construction materials delivered to site (aggregates, cement, asphalt, steel, concrete, pipes, ducts, cables, geotextiles, paints, waterproofing, etc.).
• Verify delivery notes, mill certificates, batch numbers, manufacturing dates, and shelf life against approved material submittals.
• Check material quantities, packaging condition, markings, and traceability.
• Reject and segregate any materials that do not comply with approved submittals or project specifications, and report to the Material Engineer.

Sampling & Testing

• Carry out and witness sampling of soils, aggregates, asphalt, concrete, steel, water, and utility materials in accordance with approved Inspection & Test Plans (ITPs) and project specifications.
• Ensure sampling frequencies, methods, and labelling comply with ASTM, BS EN, AASHTO, and RTA / DM standards.
• Coordinate transport of samples to the site laboratory or to approved third-party DAC-accredited laboratories.
• Witness testing at site and external laboratories and verify that test procedures are followed correctly.

Roadworks Inspection

• Inspect subgrade, subbase, aggregate base course (ABC), and asphalt binder/wearing course layers for compliance with approved materials and methods.
• Witness compaction tests (Field Density Test, sand replacement, nuclear density gauge), CBR, plate load, and Benkelman beam tests.
• Verify asphalt temperatures at delivery, placement, and compaction; check rolling patterns and joints.
• Witness core sampling, thickness measurements, and surface regularity checks.

Concrete Works Inspection

• Witness concrete pouring activities for foundations, piles, pile caps, piers, abutments, decks, walls, and slabs.
• Carry out and witness slump tests, temperature checks, air content tests, and cube/cylinder sampling.
• Verify mix delivery tickets, transit times, and discharge times against approved limits.
• Inspect curing methods, formwork release agents, repair mortars, and protective coatings.
• Witness chloride, sulfate, and durability-related tests as required by specifications.

Reinforcement & Steel Inspection

• Inspect reinforcement steel deliveries against mill certificates and approved submittals.
• Verify bar diameters, grades, cutting, bending, and fixing in accordance with approved bar bending schedules and drawings.
• Check concrete cover, spacing, lap lengths, anchorage, and tying prior to concrete pouring.
• Witness bend, rebend, and tensile testing of reinforcement samples.
• Inspect structural steel, welding, post-tensioning strands, bearings, and expansion joints as required.

Bridges & Tunnels Inspection

• Support inspection of bridge-related materials: precast segments, girders, bearings, expansion joints, and waterproofing systems.
• Inspect tunnel-related materials: shotcrete, segmental linings, waterproofing membranes, grouts, and rock bolts.
• Witness shotcrete trials, panel tests, and grout sampling.
• Verify storage and handling of precast elements, segments, and sensitive structural materials.

Infrastructure Utilities Inspection

• Inspect materials for DEWA (water and electrical), sewerage (DM), irrigation, telecom, and district cooling networks.
• Check ductile iron, GRP, uPVC, HDPE, and RCP pipes; manholes; valves; cables; and chambers against approved submittals.
• Witness hydrostatic, pressure, and leakage testing of pipelines.
• Verify backfill materials, bedding, and surround conditions in trenches.

Storage & Handling

• Inspect site storage areas, stockyards, and warehouses to verify proper storage conditions for cement, steel, pipes, chemicals, and sensitive materials.
• Check protection against weather, contamination, and damage.
• Verify that material storage complies with manufacturer recommendations and shelf-life requirements.

Quality Control & Documentation

• Maintain daily Material Inspection Reports, sampling registers, and test result logs.
• Support the Material Engineer in the preparation and update of the Material Approval Register.
• Verify Contractor's Inspection Requests (IR), Material Inspection Requests (MIR), and Work Inspection Requests (WIR).
• Issue observation notes and support the preparation of Non-Conformance Reports (NCRs) where required.

Coordination & Reporting

• Report directly to the Material Engineer on all material inspection and testing matters.
• Coordinate with Site Engineers, Land Surveyor, Safety Engineer, and the Contractor's QA/QC team, materials team, and lab technicians.
• Attend daily site coordination meetings and material-related technical meetings.
• Prepare daily and weekly inspection inputs for the Material Engineer's reports to the Resident Engineer.
