Construction Sand and Gravel Mining

NAICS 212321 · Mining (except Oil and Gas) · SBA size standard: 500 employees

Construction sand and gravel mining extracts, processes, washes, screens and stockpiles aggregates for concrete, asphalt, road base and fill. The specialists convert customer orders and project schedules into daily pit and plant production plans, manage equipment dispatch and maintenance, track inventory by grade and stockpile, handle permitting and reclamation paperwork, and coordinate truck and rail loading while maintaining dust control, stormwater compliance and safety logs.

What makes this business different

  • Daily and weekly production targets driven by construction season demand and large project schedules
  • Multiple material grades (concrete sand, mason sand, gravel sizes, crushed base, fill) that must meet ASTM and state specs
  • Pit operations with blasting, excavation, hauling, washing, screening and stockpiling sequences
  • Mobile equipment fleet (excavators, loaders, haul trucks, crushers, screen plants, wash plants) requiring preventive maintenance and fuel tracking
  • Permits for air quality, stormwater, mining reclamation, water use and endangered species plus regular inspections
  • Stockpile inventory measured by drone, GPS or survey with moisture adjustments for billing
  • Customer orders fulfilled by truck or rail with weight tickets, load tickets and chain-of-custody paperwork
  • Seasonal weather impacts on pit access, processing and reclamation schedules

Workflows

Order intake and specification

Starts when: A customer or project manager submits an order or schedule requirement

  1. Capture material type, grade, quantity, delivery method and required specifications
  2. Check against current approved sources, stockpile availability and production capability
  3. Confirm delivery or pickup window against plant schedule and haul road limits
  4. Draft the sales agreement or load authorization
  5. Create a production and loading task with full material spec

Watch for: Material must meet exact sieve analysis and cleanliness requirements; Large project orders may lock production capacity weeks in advance

Daily production scheduling

Starts when: Each morning before shift start and after weather check

  1. Review overnight orders, project call-ins and stockpile levels
  2. Set pit face, crusher, screen and wash plant targets by material type
  3. Assign mobile equipment and crews to each production step
  4. Adjust for weather, maintenance downtime or permit restrictions
  5. Publish the daily plan and load schedule

Watch for: Pit floor and face progression must follow the approved mining plan; Washing operations limited by water recycling and settling pond capacity

Equipment and crew dispatch

Starts when: At the start of each shift and when priorities change

  1. List all active equipment and required operators
  2. Assign haul routes, loading areas and dumping locations
  3. Send dispatch instructions to field supervisors
  4. Track start times, fuel use and hour meters
  5. Flag any equipment needing immediate maintenance

Watch for: Safety and dust control procedures must be followed on every route; Loaders and haul trucks operate near active pit faces and water hazards

Stockpile inventory and quality control

Starts when: Daily after production and weekly for full survey

  1. Record tons produced by grade from scale tickets and belt scales
  2. Update stockpile volumes using surveys or drone measurements
  3. Adjust for moisture content and apply specification test results
  4. Flag any pile that falls out of ASTM or state spec
  5. Generate reorder or production adjustment recommendations

Watch for: Moisture correction critical for concrete and asphalt mix designs; Segregated stockpiles must not be cross-contaminated by equipment

Fleet maintenance and parts inventory

Starts when: Daily hour-meter readings and scheduled intervals

  1. Collect operating hours and inspection results from each piece of equipment
  2. Generate preventive maintenance tasks by manufacturer schedule
  3. Track parts usage and reorder critical wear items
  4. Schedule major repairs around production windows
  5. Maintain service history for each asset

Watch for: Crushers, screens and wash plants have tight maintenance windows during the busy season; All repairs and inspections must be documented for MSHA compliance

Loading and shipping coordination

Starts when: When a truck or rail car arrives or a scheduled load is due

  1. Verify order and material specification at the scale
  2. Dispatch loader to the correct stockpile
  3. Print and attach weight ticket and material certification
  4. Record load time, destination and carrier
  5. Update inventory and customer account

Watch for: Overweight loads and axle limits must be strictly observed; Rail loading requires coordination with railroad windows

Permitting, safety and reclamation

Starts when: Daily for logs, monthly for reports and on permit milestones

  1. Generate daily dust control, stormwater and safety checklists
  2. Log water usage, fuel consumption and reclamation progress
  3. Track inspection due dates for air permits, NPDES, mining and reclamation plans
  4. Compile monthly production and sales data for state and federal reports
  5. Draft renewal applications and reclamation bond updates

Watch for: Rules differ by state and federal agencies including MSHA, EPA and local planning departments; Reclamation must follow approved grading, seeding and bonding schedule
