Engineering Discipline in Roads, Bridges and Viaducts
FTK Group's most established activity area; end-to-end engineering coordination in the design, fabrication and on-site execution of viaducts, bridges, culverts, underpasses and similar engineering structures.
Infrastructure Teams That Stay on Site
We work side by side with leading Turkish contractors on motorway main-line viaducts, urban stormwater culverts and private-sector industrial superstructure projects. We have delivered projects for large-scale employers such as Fernas İnşaat, Cengiz İnşaat, HGG İnşaat and Horozgediği Lojistik, as well as municipal authorities like MASKİ.
To date we have processed over 250,000 m³ of concrete and over 60,000 tons of reinforcement steel across five major infrastructure projects — two completed and three actively ongoing. With our 50+ expert field team, we treat on-time, on-quality and on-safety delivery as a core operational discipline.
