1. DCL Portal & Test Request Management 

• Independently navigate and operate the Dubai Central Laboratory (DCL) online portal (EMTX system). 

• Generate, submit, and manage Inspection & Test Requests (ITRs) for all materials on-site and from third-party batching plants. 

• Track test request progress, download certified test reports, and maintain a structured digital archive. 

• Coordinate directly with DCL laboratory technicians and inspectors to schedule sample pickups and witness testing. 

• Ensure all ITR submissions are complete with correct project reference numbers, lot information, mix codes, and sample descriptions. 

• Resolve portal-related discrepancies, correct data entries, and liaise with the DCL helpdesk when required. 
  

2. Materials Testing & Quality Control 

• Oversee and coordinate all construction materials testing including but not limited to: 

• Concrete: Compressive strength (cubes & cylinders), flexural strength, splitting tensile, slump, density, air content, temperature, bleeding 

• Durability: Water absorption, water penetration under pressure, ISAT, RCPT (Rapid Chloride Penetrability), chloride migration coefficient (NT Build 492) 

• Chemical: Chloride and sulphate content in hardened concrete 

• Steel Reinforcement: Tensile, yield, elongation, and bend tests 

• Asphalt: Marshall stability, bulk density, VMA, VFA, binder content, gradation analysis 

• Aggregate: Sieve analysis, Los Angeles abrasion, flakiness & elongation index, water absorption 

• Soil & Sub-base: CBR, Proctor compaction, Atterberg limits, sand equivalent, particle size distribution 

• Conduct fresh concrete tests on-site (slump, temperature, density, air content) or witness testing at the batching plant. 

• Ensure sampling frequency and testing protocols conform to approved Quality Control Plans (QCPs) and project specifications. 

• Prepare and submit trial mix designs for Consultant and Client approval, including statistical analysis reports. 
  

3. Mix Design & Material Approval 

• Develop and review concrete mix designs in accordance with project specifications (C30, C40, C50/60, C60/20 and above). 

• Prepare Method Statements and Material Submittals for Consultant and Client approval (RTA, Dubai Municipality). 

• Submit Material Approval Requests (MARs) and Track Material Approval status through the project document management system. 

• Assess and approve proposed sources of aggregates, cement, GGBS, fly ash, micro silica, admixtures, and reinforcement steel. 

• Conduct pre-qualification assessments of concrete suppliers and ready-mix plants (Unimix, Emirates Beton, Gulf Precast, etc.). 
  

4. Site Quality Assurance & Inspection 

• Inspect incoming materials against approved submittals, delivery tickets, and test certificates. 

• Issue Non-Conformance Reports (NCRs) and Corrective Action Requests (CARs) when materials or test results fall outside specification limits. 
  

5. Reporting & Documentation 

• Prepare weekly and monthly material testing summary reports, including statistical analysis of compressive strength results. 

• Maintain up-to-date Material Test Registers and compliance logs for all test types. 

• Compile Trial Mix Summary Reports encompassing fresh and hardened concrete test results for DCL and independent laboratory results. 

• Provide regular updates to the Lead Material Engineer and QA/QC Manager on materials compliance status. 

• Prepare formal correspondence for DCL lab queries, retest requests, and calibration documentation. 
  

6. Laboratory Coordination 

• Act as the primary point of contact between the site team and testing laboratories (DCL, Independent Labs). 

• Liaise with the Contractor's QA/QC team, project engineers, and subcontractors on daily material requirements. 

• Coordinate with RTA and Dubai Municipality inspectors during compliance audits and site inspections. 

• Participate in pre-construction and materials review meetings with the Consultant and Client team.
