Copenhagen’s new metro line, the City Circle Line, it is designed to carry around 130 million passengers annually between the 17 new stations. The construction project is one of the largest in the history of Copenhagen.

The City Circle Line is being excavated beneath a city which has historic buildings and strict legal requirements towards noise, vibration, transportation, the removal of contaminated soil and the management of groundwater, which will be pumped up in connection with excavation and purified so that it is cleaner than it was before when pumped back into Copenhagen’s drinking water supply. In this way, EKJ Bulgaria will ensure that the Copenhagen environment will be even cleaner than it was before construction began. Through careful planning of construction sites,

In this way, EKJ Bulgaria will ensure that the environment in Copenhagen will be even cleaner than it was before construction began. By carefully planning the construction sites, EKJ Bulgaria ensures that noise and vibration are within all legal requirements and that the construction process is thus bearable for the Copenhageners living near the sites.

EKJ Bulgaria was a subcontractor of EKJ Denmark (part of the Italian consortium contractor CMT), and our services included preparation of the Structural part of all underground facilities – tunnels and metro stations, as well as Electrical, Rail, HVAC, Plumbing, Environmental assessment, soil type and groundwater studies, geotechnical studies, hydrology, modeling and control of groundwater flow, temporary traffic organization, assessment and monitoring of existing buildings and facilities, as well as planning and design of 21 construction sites for the implementation of the construction.
