- Junction and interchange layouts (kavşak projeleri)
- Earthworks quantities and mass-haul (metraj, Brückner diagram)
- Traffic signing, marking and work-zone drawings to KGM standards
- High-speed and conventional rail alignment to AYGM specifications
- Utility relocation and coordination drawings (deplase projeleri)
We work in Turkish and English, so the same package can serve a Turkish administration and an international lender or joint-venture partner.
