Turkish to English Bus/Financial Accounting

I do not speak Turkish. Currently, I am translating The Turkish Chart of Accounts from English into Russian. In some cases, I doubt whether the initial Turkish-to-English translation is correct. As Turkish descriptions are available to me too, I need your help.

Balance Sheet Account YIL.YAYGIN İNŞAAT/ONARIM MAL.

In my file, it is translated as ACC.COSTS ON GOING JOBS

On the Internet, it is translated as "Contract progress cost"

What is this account actually intended for? I’d appreciate a short description in English.
