The E75 railway section from Sadowne to Czyżew, approximately 36 km long, is another segment being modernized on the Warsaw – Białystok line, which is part of the international transport corridor Rail Baltica. The outcome of these works includes reduced travel times, efficient transport between the capitals of Mazovia and Podlasie, and improved line capacity allowing for the operation of more connections.
The construction works were carried out by Przedsiębiorstwo Usług Technicznych Intercor sp. z o.o., for which MGGP S.A. provided comprehensive geodetic services, including: inventory of existing conditions, geodetic support during construction across all sectors (tracks with switches, platforms, drainage, roads, bridge structures, networks), establishment and measurement of the basic railway network and KOS, preparation of geodetic as-built documentation, including maps, longitudinal profiles, handover protocols for track axis adjustments, and more.
