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.
