Explaining Takt Time: The Construction Beat
Imagine a conductor leading an orchestra, ensuring each musician plays their part harmoniously. This synchronicity is the essence of takt time in construction. Here, takt time represents the calculated rate at which specific work units must be completed to meet the project deadline. The rhythmic heartbeat guides construction activities, ensuring timely completion and efficient resource utilization.
Calculating Takt Time for Your Construction Project
The formula for calculating takt time is an adaption of Little’s law to construction:
Project Duration = (Tasks + Takt Zones - 1) x Takt Time
=>
Takt Time = Project Duration / (Tasks + Takt Zones - 1)
Project Duration: The total workable timeframe for the entire project, excluding non-working days and planned downtime.
Tasks: Number of Tasks to be completed per Zone
Example
Consider a construction project with 80 units or apartments to be done in a 12-month duration. In each apartment a list of 40 tasks must be completed.
Takt Time = 12 months * 4 (weeks/month) / (40 + 80-1 ) = 0,4 week or roghly 2 days.
This 2-day takt time becomes the guiding principle for planning and scheduling all activities related to constructing a single floor. It dictates:
1. The pace at which materials need to be ordered and delivered.
2. The timeframe allocated for each trade to complete their work.
3. The coordination required between different teams to ensure a smooth handover from one activity to the next.
In construction practice instead of calculating a theoretical optimal Takt Time, the Takt Time is typically chosen and to be a week or a day for easy communication and implementation.
The challenge is then to balance the plan with work group in packages also called wagons that follows the Takt Time and have a high and stable utilization of resources across the zones and time frame as possible.
