Plant Mix Examples for Methodology‑Led Planning

Below are 60 example plant mixes for different types of work – with a strong
focus on rail, but also including energy, infrastructure, buildings, tunnels and
health projects. Each “card” represents a practical combination of plant and equipment
that works as a system to deliver a particular method.

Use these as starting points in methodology‑led estimating, scheduling, and ECC / TOC
analysis. The right fleet depends on your access windows, staging, workfaces and
productivity targets.

Need Help Selecting or Optimising Plant Mixes?

These examples are starting points. On a live project, the optimal plant mix depends on
your staging, access windows, WBS, safety constraints and ECC/TOC objectives.

We can help you:

  • Develop methodology‑based plant mixes for each stage and workface
  • Align plant fleets with realistic productivity (tpd, m/day, shifts per possession)
  • Test ECC options for different possession and staging strategies
  • Capture real performance and feed learning into future bids and planning
