Provide early-stage technical input on concrete materials during project planning and feasibility phases, identifying suitable local material sources and anticipating concrete material considerations (e.g., availability of aggregates, appropriate cement types, admixture needs) into project planning documents and design studies.
• Develop concrete materials testing plans and performance criteria for projects, establishing procedures to evaluate material properties and ensure they meet design specifications.
• Prepare and review concrete material specifications and quality control procedures that will guide material procurement and installation in compliance with industry standards and client requirements.
• Provide project phasing and constructability review for material elements.
• Lead the evaluation and approval of concrete submittals and material certifications during design and construction phases, providing expert oversight for quality assurance/quality control (QA/QC) on all concrete-related work.
• Reviewing laboratory test results, evaluating whether materials and mixes meet applicable ASTM/ACI standards, and recommending adjustments or corrective actions to address non-conformances.
• Advise on the selection of concrete materials for various project components and environmental conditions.
• Recommend appropriate cement types, supplementary cementitious materials, chemical admixtures, and curing methods to achieve required durability and service life objectives.
• Incorporate considerations for long-term performance (such as sulfate resistance, alkali-silica reactivity mitigation, and corrosion protection) into material specifications and design documents.
• Collaborate closely with structural engineers, geotechnical engineers, and hydraulic engineers to integrate concrete material considerations into overall project designs.
• Develop material performance requirements that align with structural design needs and ground conditions, supporting a holistic approach to design quality.
• Participate in multidisciplinary design reviews and risk assessments by providing specialized input on concrete behavior and material-related design decisions.
• Provide technical leadership during concrete construction phases by overseeing material-related activities.
• Monitor field performance of concrete (through strength tests, inspections, etc.) and troubleshoot material issues or deviations from specifications, implementing solutions to maintain quality.
• Serve as a mentor and technical resource for mid-career engineers and other team members in the field of concrete materials engineering.
• Lead or contribute to internal quality reviews of project deliverables related to concrete materials, such as specifications, drawings, and reports.
• Review documentation and design outputs for conformance with company standards and client material requirements and perform high-level reviews of material test data and contractor submittals for compliance and accuracy.
• Provide input on project scheduling, budgeting, and constructability as it relates to concrete materials. Evaluate how material choices and specifications may impact project costs, construction schedules, and methodologies.
• Advise project managers and clients on cost-effective, practical material solutions (e.g., alternative cement blends or aggregate sources) that achieve performance goals without compromising quality or safety.
• Maintain effective communication with project managers, clients, and team members regarding material performance expectations, specifications, and issues that arise. Participate in client meetings and presentations to explain technical aspects of concrete materials and ensure stakeholder alignment on materials-related decisions.
