Why the template separates civil, steel, and equipment work
Aggregate plants look like equipment projects, but installation quality depends heavily on foundation readiness, access platforms, transfer points, and chute interfaces.

What is included in the schedule structure
Each phase exists for a reason. The template separates civil readiness, steel access, process equipment, conveyors, electrical controls, commissioning, and handover so you can adjust the plan without losing the construction logic.
| WBS | Phase | Typical tasks | Why it matters | Duration |
|---|---|---|---|---|
| 1 | Project Preparation | Contract kickoff, design review, procurement planning, schedule baseline | Locks the process flow, layout assumptions, and long-lead equipment plan before field work starts. | 5-10 days |
| 2 | Site Preparation | Survey, clearing, access road, temporary power, temporary facilities | Creates safe access and temporary utilities for concrete, steel erection, equipment delivery, and lifting work. | 10-20 days |
| 3 | Civil Works | Excavation, equipment foundations, retaining walls, drainage, concrete curing | Crusher, screen, conveyor, and transfer tower installation cannot start reliably until foundations are ready. | 25-40 days |
| 4 | Steel Structure | Column installation, platforms, stairs, handrails, chute supports | Platforms and supports define access, chute interfaces, and the workface for mechanical installation. | 15-25 days |
| 5 | Equipment Installation | Jaw crusher, cone crusher, vibrating screens, feeders | Major process equipment sets the mechanical path that conveyors, cabling, and testing must follow. | 20-35 days |
| 6 | Conveyor System | Belt conveyor supports, pulleys, belts, drives, guards, transfer points | Conveyors connect the process line; no-load and loaded tests depend on stable transfer points. | 15-30 days |
| 7 | Electrical and Controls | Cable trays, MCC panels, motor wiring, sensors, PLC cabinets, control room | Motors, sensors, interlocks, and PLC controls must be ready before integrated commissioning. | 20-35 days |
| 8 | Commissioning | Dry run, single machine test, interlock test, load test, dust and water system checks | The plant must prove single-equipment, no-load, interlock, and loaded operation before acceptance. | 10-20 days |
| 9 | Handover | Punch list, training, documentation, acceptance, final handover | Final records, training, punch list closure, and performance acceptance turn the schedule into a deliverable plan. | 5-10 days |
Why this schedule is structured this way
The template is not only a task list. It reflects the construction logic behind aggregate processing plants: foundations, access steel, process equipment, conveyors, controls, and commissioning all constrain each other.
Why conveyors appear as their own phase
A plant may have several crushers and screens, but material flow depends on conveyors, pulleys, drives, guards, belts, belt scales, and transfer points working together.
Why commissioning is not a single final task
Single equipment dry run, conveyor no-load test, interlock test, loaded trial run, product gradation adjustment, and performance verification are different checks.
Key dependencies to review
Before you use the template as a baseline, review these dependency groups. They are common schedule drivers in fixed crushing, screening, and sand-and-gravel processing projects.
Civil foundations drive the installation start
Crusher foundations, screening workshop foundations, and transfer tower foundations must be complete and cured before most mechanical work can start.
Steel structure controls access and transfer points
Platforms, supports, handrails, chutes, and transfer towers define where screens, feeders, conveyors, and dust systems can be installed.
Electrical and controls are commissioning prerequisites
Motor cabling, MCC setup, PLC/HMI configuration, instruments, and safety interlocks must be ready before integrated no-load and loaded tests.
Loaded trial run comes before product adjustment
Gradation adjustment and performance verification should happen after the plant has passed interlock checks and loaded trial operation.
Resource and cost notesResource peaks usually appear before commissioning, not only at handover.
- Civil crew demand peaks around foundation excavation, reinforcement, pouring, and curing coordination.
- Crane and mechanical crew availability can constrain crusher, screen, feeder, and transfer tower installation.
- Electrical crew demand usually peaks when cable trays, motor cabling, terminations, PLC work, and instruments overlap.
- Commissioning engineers, operations staff, and maintenance staff should be reserved before no-load and loaded trial runs.
How to customize this template
Use the CSV as a planning worksheet, or open the Gantt version in GanttPilot and adjust the dates, task names, durations, dependencies, resources, and milestones to match your actual project.
- Update the plant capacity, process flow, and equipment list.
- Adjust civil foundation work around site conditions and curing time.
- Connect delivery, installation, cabling, commissioning, and handover tasks.
- Use the Gantt view to inspect downstream impact when dates move.
Template workflowAdjust the template only after checking scope, delivery dates, access, and commissioning constraints.
When the sequence changes, review downstream tasks such as conveyor installation, motor cabling, interlock testing, loaded trial run, and final handover. These are where small date changes often create real schedule pressure.
Common questions
What is included in this aggregate processing plant schedule template?
The template includes preparation, site work, civil foundations, steel structure, equipment installation, conveyors, electrical and controls, commissioning, loaded trial run, product adjustment, performance test, and handover tasks.
Can I download the schedule template?
Yes. The CSV download includes the sample task list, phase labels, durations, and dependencies shown on this page.
Can I open this template in GanttPilot?
Yes. The Open in GanttPilot action loads the aggregate processing plant schedule as an editable Gantt project.
Can I use this template for a sand and gravel plant?
Yes. It can be adapted for sand and gravel processing plants, quarry crushing lines, manufactured sand systems, and fixed aggregate production facilities.
What dependencies affect crusher and conveyor installation?
Civil foundations, concrete curing, steel supports, transfer towers, equipment delivery, and electrical readiness are the main dependency groups to review.
How long does aggregate plant commissioning take?
The example allows 10-20 days for commissioning, but the actual duration depends on equipment count, interlock complexity, loaded trial results, and product gradation adjustment.
Is this a finished project schedule?
No. It is a starting template. Review task scope, durations, resources, delivery dates, site access, and commissioning requirements before using it as a baseline schedule.
