🎯 Role Definition

The Construction Materials Engineer is responsible for ensuring the quality, durability, and performance of construction materials used in infrastructure and building projects. This role leads laboratory and field testing (concrete, asphalt, soils, aggregates, admixtures, geosynthetics), develops and verifies mix designs and specifications, supports construction QC/QA programs, conducts failure investigations and root cause analyses, and provides technical guidance to project teams, contractors and suppliers. The ideal candidate combines hands-on lab experience, strong knowledge of industry standards (ASTM, AASHTO, ISO), practical field sampling skills, and the ability to translate test data into actionable recommendations that reduce risk, control cost, and improve project outcomes.

Core Responsibilities

Primary Functions

  • Develop, evaluate and optimize concrete mix designs (including SCC, high-performance concrete, fiber-reinforced mixes) and asphalt mix designs (HMA, WMA, SMA) to meet structural, durability and constructability criteria while aligning with project specification, budget and schedule.
  • Plan, perform and document laboratory testing on construction materials (slump, compressive strength, CBR, gradation, Atterberg limits, moisture-density relationships, Marshall, Superpave, indirect tensile, resilient modulus), ensuring tests adhere to ASTM, AASHTO and project-specific procedures.
  • Establish, implement and maintain QA/QC programs for materials on projects, including sampling plans, acceptance criteria, statistical process control, documentation of non-conformances and corrective action tracking.
  • Conduct field sampling and inspection of fresh concrete, asphalt placement, soils and aggregates; verify compaction, placement techniques, curing, and in-place densities to confirm compliance with specifications.
  • Lead materials-related pre-construction reviews and submittal evaluations (mix designs, source approvals, supplier qualifications), coordinating with designers, contractors and suppliers to resolve specification or constructability issues prior to mobilization.
  • Perform on-site troubleshooting during placement and curing (concrete bleeding, segregation, asphalt segregation, rutting or soft spots) and provide immediate technical direction to crews to mitigate defects and avoid rework.
  • Manage and maintain an accredited materials laboratory or oversee lab vendors, including calibration of equipment, maintenance of testing apparatus, LIMS data entry, and certification records to preserve laboratory accreditation and data integrity.
  • Prepare detailed technical reports, laboratory summaries, test result analyses, daily field logs, and formal documentation for change orders, claims, or dispute resolution; present findings to clients, contractors, and regulatory agencies.
  • Execute root cause investigations of material failures, distress (cracking, spalling, rutting, faulting) or poor durability; perform forensic sampling, laboratory forensic testing, and recommend remedial repair strategies with cost and schedule impact assessments.
  • Review and interpret contract specifications, project drawings, standards and vendor data to create clear material acceptance criteria and test plans that align with owner and regulatory requirements.
  • Evaluate aggregate sources, admixture products, cement types, asphalt binders and specialty materials for suitability and long-term performance; perform source sampling and qualification testing to support material approvals.
  • Monitor and implement material sustainability initiatives including recycled content (RAP, RCA), supplementary cementitious materials (fly ash, slag), embodied carbon reduction strategies and life-cycle considerations, balancing performance, durability and environmental goals.
  • Provide technical support during contractor pre-construction meetings, daily construction operations and commissioning to ensure materials performance targets are met and to reduce workmanship-related defects.
  • Support procurement and supplier development by developing material specifications, participating in supplier audits, and qualifying alternate materials or vendors through trials and performance testing.
  • Use statistical analysis and quality tools (ANOVA, control charts) to interpret data trends, identify process drift, and drive continuous improvement in material performance and field installation practices.
  • Collaborate with design teams to incorporate constructability feedback and performance-based material recommendations into design documents, specifications, and value-engineering proposals.
  • Supervise, mentor and train laboratory technicians, field inspectors and junior engineers on testing protocols, safety procedures, data management, and best practices for materials handling and documentation.
  • Ensure compliance with environmental, health and safety regulations during sampling, testing and on-site operations; participate in safety planning and materials handling risk assessments.
  • Support development and validation of new testing methods, instrumentation and automated data collection systems; pilot emerging technologies such as non-destructive testing (NDT), sensor-based monitoring of curing, and digital LIMS integration.
  • Coordinate with geotechnical, structural and pavement engineers to evaluate subsurface material interactions, pavement layer design, and long-term performance predictions under traffic and environmental loading.
  • Prepare budgetary estimates for materials testing programs, lab operation costs and field inspection scopes; track expenditures and optimize testing frequency to meet contractual and regulatory needs while controlling costs.
  • Participate in claims management, litigation support and expert testimony by preparing technical exhibits, testimony materials and affidavits related to material performance and testing results.

Secondary Functions

  • Support project-level data collection and materials databases to enable trend analysis, reporting, and continuous improvement efforts across portfolios.
  • Contribute to cross-functional initiatives such as Life Cycle Assessment (LCA) for materials selection and sustainability reporting for infrastructure projects.
  • Assist business development teams with technical proposals, scope definitions, and pricing for materials testing and QA/QC services.
  • Maintain and update laboratory procedure manuals, training materials and SOPs to reflect changes in standards and best practices.
  • Participate in industry committees, standards development or continuing education to keep team practices aligned with evolving ASTM/AASHTO/ISO guidance.
  • Support ad-hoc technical requests from clients, regulatory agencies or internal project teams, including expedited testing and field consultation.
  • Coordinate third-party testing and validation with external laboratories, NDT providers and material suppliers when specialized testing beyond in-house capabilities is required.
