German to Portuguese Bus/Financial Accounting

Será que me poderiam ajudar com um termo em alemão que me apareceu no meio de um trabalho?
“Baukasse”

O contexto é o seguinte:

Cost Controller (CR)
The Cost Controlling is reporting directly to the CPD and has responsibility for the following matters:
- Cost control / onshore (income, expenses, allocation);
- Clarification of accounting matters with company;
- Records and control of personnel related costs;
- Orders and payments;
- Invoicing of milestones;
- Administration matters;
- Baukasse.


Agradeço desde já a vossa ajuda.
