QC / R&D Manager · Ready-Mix Optimization Specialist · Transportation Manager
GCC
El Paso, TX
06.2017 - 08.2024
- Directed ready-mix QC and R&D for 6 plants — pilot testing, product development, audits, corrective actions, and mix-performance analysis to ensure spec adherence and reduce rejections.
- Applied Minitab, SPC, DOE, strength-performance analysis, and ACI 318 required-strength calculations to reduce variation, improve product consistency, and support cementitious reductions.
- Delivered ~$1.2M/year in material cost savings by leading KPI-driven mix-design optimization and cementitious-efficiency analysis across ready-mix operations.
- Built Tableau and Power BI dashboards centralizing QC, production, and performance KPIs improving leadership visibility into cost variance, trends, and corrective-action priorities.
- Led ready-mix delivery-network optimization using ArcGIS Pro — analyzed 2022–2023 delivery coordinates, plant service areas, and haul distances to improve dispatch reliability, fleet utilization, and staffing alignment, reducing average haul time 9%.
- Established KPI framework for 58-truck fleet, standardizing cy/driver-hour, loading-time, and trip-cycle tracking, increased productivity from 1.54 to 2.2 cy/driver-hour.
- Managed concrete delivery for USACE Biggs Army Airfield runway reconstruction (66,000 CY, delivered ahead of schedule), SpinLaunch mass-accelerator foundation (10,000 CY continuous pour over 46 hours, zero delays), and TxDOT I-10 infrastructure projects.
