Construction Cost Code in Switzerland (BKP/CFC)

Discover how the Swiss Construction Cost Code (BKP/CFC) standardises project budgeting. Learn how the construction standard cost code list, BKP code, and Code CFC simplify cost control, communication, and comparisons in construction in Switzerland.

In the field of construction in Switzerland, projects are frequently organised and budgeted with the help of a construction standard cost code list. This system, commonly known as the BKP code in German or Code CFC in French, provides a uniform way of breaking down and classifying all expenses related to a building project. It supports consistent communication between architects, engineers, contractors, and clients, while also serving as a practical tool for structuring the project itself.

Understanding the Construction Cost Code

The BKP code or Code CFC represents a harmonised framework for documenting and tracking building costs. Standardised by the Swiss norm SN 506 500, each task within a project is assigned a numeric code, ranging from one to four digits. The more digits used, the more specific the categorisation becomes.

For example:

• The first digit identifies the main category.
• The second digit refines the activity into a sub-category.
• Additional digits bring further precision.

The hierarchy generally mirrors the chronological flow of construction tasks, and in practice, many of these entries correspond directly to individual contracts or service orders.

Why use the Construction Cost Code?

Applying the construction standard cost code list provides multiple benefits:

• Streamlined cost control: Estimates and offers structured by the code can be directly used for budget planning and cost monitoring.
• Improved communication: Since all stakeholders use the same framework, misunderstandings are minimised, and collaboration improves.
• Comparability across projects: Because the coding is standardised, it allows quick and transparent comparisons between offers and projects.

Conclusion

The BKP code / Code CFC is a cornerstone of modern construction in Switzerland. By ensuring a standardised and transparent method of organising costs, it fosters clarity, efficiency, and fairness in project management. Whether for architects, engineers, or property owners, this system provides a common language for budgeting and evaluating offers, ensuring projects run more smoothly from planning to completion.
