In the construction sector, efficiency and precision are key to the success of any project. In this context, the BC3 file is the standard in Spain for exchanging estimates, measurements, and project data between different software programs.
In this article you will learn what the BC3 file is, how it works, what it is used for, and how you can use it in tools like Trowel.
What is a BC3 file?
The BC3 file, also known as the FIEBDC format, is a standardized text file used in construction to exchange estimates, measurements, and certifications between different programs.
This format was developed by the Higher Council of Architects' Associations of Spain (Consejo Superior de los Colegios de Arquitectos de España — CSCAE) with the goal of facilitating interoperability between systems.
Before its adoption, estimates had to be entered manually into each program, which generated more work time and more errors.
Today, the BC3 file allows different tools to work with a common language, ensuring data remains consistent throughout the project.
It is also known as:
- FIEBDC format
- Standard interchange file
- Construction database
- BC3 format estimate
Structure of a BC3 file
Although the BC3 file is a plain text file, it has an organized structure that allows it to be interpreted by different programs.
It is composed of four main blocks:
**Header **Includes general project data, such as the name, client, date, and file version.
**Body **Contains all the estimate line items. These are organized hierarchically and include:
- Chapters
- Measurements
- Unit prices
- Resources (materials, labor, and equipment)
- Totals per line item
**Totals **Shows the final cost of the project, including taxes and other expenses.
**Notes and observations **Space for adding comments or other relevant additional information.
BC3 file versions
Over time, the BC3 format has evolved to meet the needs of the sector:
- BC3: original version, basic and functional
- BC3 v2: improves structure and compatibility
- BC3 v3: more advanced version, designed for complex projects
You can check the version of the BC3 format on the official FIE | BDC website.

How is the BC3 file used in construction management?
The BC3 file is used at different stages of a construction project. These are its most common uses:
1. Estimating
This is the most common use. The technician creates the estimate in their software and exports it in BC3 format.
Other companies can then import it directly, without errors or duplication.
2. Public works tenders
In Spain, the BC3 file is the standard format for public tenders.
This allows the administration to compare bids automatically and much more quickly.
3. Construction progress billing
During project execution, BC3 is also used to update measurements and generate certifications in a traceable way.
This improves the financial control of the project.
4. Integration with price databases
Many databases such as CYPE or ITeC work with the BC3 format.
This allows updated prices to be imported without having to enter them manually.
Advantages of the BC3 file in construction
Using the BC3 file brings clear benefits to project management:
- Interoperability: works with most software programs in the sector
- Error reduction: avoids manual data entry
- Time savings: import and export in seconds
- Better cost control: full traceability from estimate to billing
How to open a BC3 file in Trowel
Opening a BC3 file in Trowel is a simple process:
- Log in to your Trowel account
- Go to the Estimates section
- Click Import
- Select the BC3 file from your device
- Verify that the data has been imported correctly
- Save the estimate and start working with it
Conclusion
The BC3 file is a key standard in construction in Spain. It allows information to be shared accurately, quickly, and without errors between different programs.
Its use improves efficiency at every stage of the project, from the initial estimate to the final certifications.
Furthermore, its integration with digital tools like Trowel simplifies site management and improves financial control of the project.
In short, mastering the use of the BC3 file is an important advantage for any professional in the construction sector.
