Concrete Batch Plant Operator (Sunmat)

Plant Operation & Batching

• • Operate the Erie Strayer MG-12CP central-mix plant and associated systems (cement silos, aggregate stackers, water heaters, dust collection, and water reclamation) in accordance with manufacturer specifications and Sunmat standard operating procedures.
• • Execute batch tickets through the Command Alkon Integra 10 batching system and Apex dispatch platform; verify mix design, load size, target slump, air content, and admixture dosing prior to release.
• • Calibrate and verify scale accuracy daily; maintain moisture probe calibration on fine and coarse aggregate bins; document all calibration activity in the plant log.
• • Coordinate cement, fly ash, fine aggregate, coarse aggregate, lightweight aggregate, and admixture deliveries; verify quantities, monitor silo levels, and prevent commingling or cross-contamination of raw materials.
• • Adjust mix designs in real time within authorized tolerances to compensate for ambient temperature, aggregate moisture, and slump-loss conditions; escalate any out-of-tolerance condition to the Plant Supervisor and QC.

Quality Control & Specifications

• • Produce concrete in strict conformance with approved mix designs, ASTM C94, ACI 301 / 318, and Micron-issued project specifications.
• • Coordinate with the Sunmat QA/QC team and field testing technicians on sampling, slump and air checks, temperature monitoring, cylinder casting, and rejection thresholds; will not release any load that fails to meet acceptance criteria.
• • Manage hot- and cold-weather concreting protocols using the Sioux water heaters and American Geothermal hot water system; document concrete temperature at the point of discharge for every load during temperature-controlled placements.
• • Maintain accurate batch records, ticket archives, mix design files, and material certifications in audit-ready condition.

Mixer Truck Dispatch & Customer Service

• • Dispatch and stage mixer trucks across the 40-unit fleet to meet placement-rate requirements established by the GC and the field placement crew; balance pour demand across the three plants on site.
• • Communicate clearly and professionally with Suntec field crews, Layton Construction field staff, Micron representatives, and third-party testing agencies via radio and dispatch systems.
• • Track truck cycle times, in-truck wait times, and discharge times; flag chronic delays and propose dispatch adjustments to the Plant Supervisor.

Environmental Compliance & Water Management

• • Operate the OZB CRS water reclamation system and HDPE-lined process water containment in full compliance with the site's stormwater and process water management plans; ensure zero discharge of untreated process water.
• • Maintain compliance with IDEQ Air Permit P-2023.0026 at all times: monitor and verify operation of the C&W RA-200 central dust collectors, silo vents, baghouse differential pressure, and all permitted opacity limits; log all required parameters.
• • Operate the Vortomech steam generators within manufacturer and permit limits; maintain logs for the de minimis water-heating equipment.
• Promptly report and document any deviation, upset condition, exceedance, or near-miss to the Plant Supervisor, Environmental Lead, and QA/QC Technical Advisor.

Safety & Site Stewardship

• • Comply with all Suntec, Sunmat, and Micron safety policies, including site-specific PPE, lockout/tagout, confined space, fall protection, and hot work requirements.
• • Conduct daily pre-shift inspections of the plant, conveyors, stackers, silos, dust collection, water systems, and surrounding work areas; tag and isolate any unsafe condition.
• • Complete digital JHAs and pre-task plans through Safety Culture (iAuditor) at the start of each shift and any time conditions change.
• • Maintain housekeeping standards across the plant pad, truck wash area, aggregate storage area, and reclaim system.

Maintenance & Reliability

• • Perform routine operator-level preventive maintenance: greasing, belt inspections, hose changes, pneumatic system checks, and cleanup of mixers, weigh hoppers, and conveyors.
• • Coordinate with the Sunmat maintenance team and equipment vendors (Erie Strayer, C&W, Kraft Tank, Sioux, Vortomech, OZB) on warranty work, scheduled service, and unscheduled repairs.
• • Operate the BE Power Equipment electric truck wash system and the Elgin Waterless Eagle street sweeper as needed to maintain site cleanliness.
• Document equipment runtime, alarm conditions, and downtime causes in the Sunmat plant availability reporting system.

Records, Reporting & Continuous Improvement

• • Complete daily plant production reports, batch volume summaries, raw material inventory counts, and shift handoff documentation.
• • Contribute to plant KPIs in the five Sunmat performance categories: Safety, Environmental Compliance, Plant Availability, QA/QC, and Gray Water Recycling.
• Identify and recommend process improvements that increase throughput, reduce waste, or improve mix quality; participate in shift-change toolbox talks and continuous improvement reviews.

Requirements

Required

• • High school diploma or equivalent.
• • Minimum three (3) years of hands-on experience operating a central-mix or transit-mix concrete batch plant; experience on Erie Strayer or comparable high-volume plants strongly preferred.
• • Working proficiency with Command Alkon Integra and Apex, or demonstrated ability to become certified within ninety (90) days of hire (training provided).
• • Working knowledge of ASTM C94, ACI 301 / 318, mix design fundamentals, and admixture chemistry.
• • NRMCA Concrete Plant Operator Certification, or ability to obtain within six (6) months of hire.
• • Valid driver's license; ability to obtain Micron site access credentials and complete all owner-required orientations.
• Ability to read, interpret, and execute concrete mix designs, batch tickets, project specifications, and equipment manuals.
• Strong written and verbal communication skills; comfortable on a two-way radio across multiple channels in a high-volume placement environment.

Preferred

• • Experience on large-format semiconductor or industrial mission-critical projects (Micron, Intel, TSMC, Samsung, or comparable).
• • Experience with mass-concrete pours, lightweight concrete, low-shrinkage mixes, and high-early-strength designs.
• • Familiarity with IDEQ air permitting and stormwater/process water compliance requirements.
• • Experience with water reclamation systems (OZB, BFK, or equivalent).
• OSHA 10 or OSHA 30 General Industry / Construction certification.
