2. Materials Testing & Quality Control

• Supervise testing of:
• Concrete (fresh and hardened)
• Cement and admixtures
• Aggregates (gradation, abrasion, etc.)
• Soils and earthworks (compaction, classification, permeability)
• Rock materials (for dam foundations and embankments)
• Ensure accuracy and reliability of test results.
• Validate mix designs for structural and mass concrete used in dam construction.
• Monitor mass concrete temperature control and cracking risk mitigation.

3. Compliance & Reporting

• Ensure all testing aligns with:
• Project technical specifications
• International standards (ASTM, BS, AASHTO, ISO)
• Client/Engineer requirements
• Prepare and review:
• Test reports and certificates
• Quality control reports
• Non-conformance reports (NCRs)
• Maintain detailed laboratory records and traceability of materials.

4. Coordination & Communication

• Coordinate with:
• Construction teams (site engineers, contractors)
• Quality Assurance/Quality Control (QA/QC) teams
• Client representatives and consultants
• Provide technical advice on materials performance and suitability.
• Support inspections, audits, and third-party testing.

5. Mix Design & Technical Support

• Develop and optimize concrete mix designs, especially for:
• Mass concrete (dam body)
• High-strength structural elements
• Durability in aggressive environments
• Analyze test data to improve material performance and reduce risks.
• Support troubleshooting for:
• Concrete defects
• Strength issues
• Material inconsistencies

6. Personnel Management

• Supervise laboratory technicians and staff.
• Train team on testing standards, safety procedures, and best practices.
• Ensure adequate staffing and competency levels.

7. Health, Safety, and Environmental Compliance

• Enforce strict adherence to HSE policies within the laboratory.
• Ensure safe handling of chemicals, materials, and testing equipment.
• Maintain a clean, organized, and hazard-free work environment.

Qualifications & Requirements

education

• Civil Engineering
• Materials Engineering
• Geotechnical Engineering
• or related field

experience

• 7-15+ years of experience in construction materials testing.
• Strong experience on large-scale infrastructure projects (hydropower, dams, bridges, or heavy civil works).
• Proven experience with mass concrete and dam construction preferred.

Technical Skills

• Deep knowledge of:
• Concrete technology (especially mass concrete)
• Soil mechanics and earthworks
• Rock testing (preferred)
• Proficiency in standards:
• ASTM, AASHTO, BS, EN, or equivalent
• Familiarity with laboratory quality systems (ISO 17025 is a plus)

Soft Skills

• Strong leadership and team management ability
• High attention to detail and analytical thinking
• Excellent communication and reporting skills
• Ability to work in remote, project-site environments

Certifications (Preferred)

• ACI (American Concrete Institute) Certification
• Laboratory Quality Management (ISO 17025)
• Relevant national/international material testing certifications

Key Performance Indicators (KPIs)

• Accuracy and timeliness of test results
• Compliance with project specifications and standards
• Reduction in material-related defects or rework
• Laboratory audit and inspection outcomes
• Efficiency of laboratory operations

Working Conditions

• Site-based role in a remote construction environment
• May involve extended working hours aligned with project schedules
• Exposure to construction site conditions

Additional Notes

This role is critical to ensuring the long-term safety and performance of the dam structure, particularly given the complexity of mass concrete placement, thermal control, and geotechnical conditions in hydropower projects.
