Splitting a crew across two areas: test both workfaces before keeping the split
The upper floor is released, and the foreman considers sending half the crew up. The only material lift still serves the lower workface. Two starts would look better on the report, but neither crew has an agreed supply or leadership arrangement.
Split a crew only when both workfaces can support useful finished work. Check leadership, task needs, tools, supply and incoming conditions before testing the allocation. Compare each group's output per person-hour and the combined result, with differences in scope visible. A second start is not automatically a second productive workface, and one lower rate is a question to investigate rather than an automatic instruction to recombine.
Test the allocation rather than the appearance of progress
- Define two complete packages. Name each area, work quantity and receiving handoff. Check that both have the required information and releases; do not divide a task that needs the approved crew arrangement without the responsible lead's assessment.
- Assign leadership to each group. Identify who sets the work, answers routine questions and checks completion. Confirm competence and supervision arrangements instead of expecting one foreman to remain physically available in two separate places.
- Check tools and supply independently. List shared equipment, material deliveries and access demands. Resolve conflicts with their owners before the trial, including which group receives a scarce resource and what the other can genuinely do meanwhile.
- Set a short, monitored test. Agree the trial period and earlier checkpoints with the crew. Record the initial allocation and conditions, while retaining the required safety and technical controls. A week is a possible review period, not permission to leave a known problem untreated.
- Count comparable results separately. Record each group's completed quantity, person-hours, waiting and rework. Compare similar work on the same basis, then read the combined output and receiving handoffs rather than choosing the group with the best raw quantity.
- Act on the supported constraint. Check whether the problem is readiness, supply, leadership or the allocation itself. Confirm the next arrangement—retain, redistribute or recombine—with its leads and dependencies, then tell the affected trades what changes.
Common mistakes
- Splitting people while leaving one group without a lead or supply.
- Comparing raw quantities from different work types.
- Celebrating two starts while both receiving handoffs remain incomplete.
Checklist
Evidence for the next allocation
- Ready packages and intended handoffs.
- Leadership and resource arrangements.
- Separate quantity and person-hour records.
- Located waiting and scope differences.
- Supported cause, chosen allocation and next check.
Check your understanding
The upper crew's rate is lower, but its work includes more difficult details. Should you recombine immediately from that comparison?
