A takt plan for repeating floors: one pace for every trade, drawn as a zone-by-week grid
The first apartment floor is nearly finished, but three trades are waiting outside the same suite. The next floor has started with a different sequence. Repetition is increasing the confusion because nobody has agreed what one ready zone looks like.
A takt plan gives repeating work a shared rhythm: trades move through defined zones in an agreed sequence at a common planning pace. The Lean Construction Institute describes balancing trade durations and work areas as part of this approach. Start by testing the amount of work and available capacity, rather than imposing a weekly move because the calendar looks tidy. A grid is useful only when its handoffs can actually be met.
Draw a pace the trades can test
- Choose comparable zones. Mark boundaries on the plan and list the work in each. Equal floor areas may contain different effort; a service-heavy zone needs a different discussion from a run of similar rooms.
- Agree the trade sequence. Ask each foreman what must be finished, checked and protected before that crew enters. Record interfaces that prevent two operations sharing a zone, including access and inspection dependencies.
- Estimate the work inside each period. Have the trades identify quantities, proposed crew capacity and other tasks using those people. Test more than one period length rather than presenting your first grid as a commitment.
- Draw zones against periods. Give each trade a clearly labelled position and show the handoff between periods. Use readable names as well as colour so a printed sheet or unfamiliar reader can follow the sequence.
- Expose missing readiness. Put outstanding releases, material availability and decisions beside the affected zone. Assign someone to clear each constraint before the planned entry, rather than allowing a blocked zone to masquerade as ready.
- Trial and adjust together. Observe the first zones and compare the planned work with completed results. Change zone boundaries, crew allocation or the proposed pace openly, then issue one agreed revision to everyone affected.
Common mistakes
- Sizing zones by floor area without discussing their actual work.
- Using colour alone to identify trades.
- Calling a planned handoff complete while required checks remain open.
Checklist
Before issuing the takt grid
- Zones have clear boundaries and comparable work.
- The trade sequence and entry conditions are agreed.
- Crew capacity has been tested against the proposed pace.
- Outstanding readiness items have owners.
- The first-zone trial and revision process are clear.
Check your understanding
One trade cannot meet the proposed period with its available crew. Should you leave the grid unchanged and ask it to catch up?
