Roadways nad Railways

We participate in the preparation and implementation of significant road and railways infrastructure

We provide engineering services for the preparation and implementation of roadway and railway constructions. We design infrastructure not only compatible with current demand, but also anticipate future capacity requirements, reduce impact of the construction to environment and improve the quality of life of those it serves. We have experience since 1995, when the main railways in the Czech Republic were modernized. SG Geotechnika has been a geodetic consultant for Czech Railways from the beginning of these large-scale construction projects.
