How to use this glossary
The Santix interface is in Turkish, and so is most paperwork on a Turkish site. The English equivalents here are the closest common terms, not exact legal translations. For official definitions on public works, see the General Specification for Works (Yapım İşleri Genel Şartnamesi) and the relevant laws. Rates and periods are general rules; confirm them with your accountant or lawyer.
