The one-piece application in lean construction is an approach to optimizing individual part production and assembly. Each component is manufactured and assembled individually and according to demand in order to reduce waste and inefficient processes.

The main principles of the One-Piece application are:

• Just-in-time production: One-piece application aims to produce and deliver components exactly when they are needed in order to reduce inventory levels and unnecessary waiting times.
• Custom manufacturing: Each component is manufactured individually and according to requirements in order to meet the specific demands of the project and minimize waste.
• Efficient assembly: The components are assembled quickly and precisely in order to shorten throughput times and ensure the quality of the work.

The advantages of the one-piece application in lean construction include:

• Reduction of waste: Customized manufacturing and just-in-time production reduce inventory levels, unnecessary waiting times, and waste.
• Higher quality: Demand-oriented manufacturing and efficient assembly ensure higher quality components and end products.
• Shorter turnaround times: One-piece application enables shorter lead times and faster completion of construction projects.
