Solutions
Managing multiple sites along the long route accelerated the schedule.
International standard environmental protection methods were applied at terrain crossings.
Specially trained teams and round the clock site inspections ensured occupational health and safety.
Sustainability
Energy and Resource Management
Modern equipment and low emission machinery reduced construction energy consumption.
Steel pipes from internationally certified suppliers ensured quality and long life.
Water Management
Special crossing methods, HDD and microtunneling, protected water resources along the route.
Construction minimized effects on groundwater and surface water.
Waste Management and Material Use
Welding and coating waste was separated and disposed of.
Excavated materials were assessed for reuse.
Reducing Environmental Impacts
Site rehabilitation protected flora and fauna during construction.
Local materials and labor reduced the carbon footprint of logistics.
Long Term Sustainability
Continuous monitoring and maintenance systems ensured line safety.
Modern valve stations minimized environmental risks from potential leaks and emergencies.
Four pigging stations, 10 block valve stations and power supply and access roads for 14 aboveground facilities were also constructed, expanding the line's operating and maintenance capabilities.
Kalyon İnşaat undertook the Lot 4 segment and completed construction of a 472 km, 48 inch pipeline.
