Heijunka is a method for evenly distributing workloads and resources in production processes. In lean construction, heijunka is used to avoid bottlenecks, increase the efficiency of construction processes, and reduce waste.

The main principles of Heijunka are:

• Even distribution of the workload: Heijunka aims to distribute the workload and use of resources evenly throughout the entire construction process.
• Flexibility and adaptability: Heijunka makes it possible to respond quickly to changes in the course of a project and adjust the workload accordingly.
• Reducing bottlenecks: The even distribution of the workload prevents bottlenecks that can lead to delays and waste.

The advantages of Heijunka in Lean Construction include:

• Greater efficiency: The even distribution of the workload and the avoidance of bottlenecks contribute to increasing the efficiency of construction projects.
• Reduction of waste: Heijunka helps to make optimal use of resources and minimize waste caused by overloading or underutilization.
• Improved adaptability: The flexibility and adaptability of Heijunka enable a faster response to changes in the course of a project.
