GEODETIC NETWORKS
• Accurate Surveying Network is the fundamental factor
for a successful construction of a Tunnel. Unfortunately,
its high importance can be evaluated only through
failure.
• By using high-end equipment, delicate techniques
and methodologies, but mostly by gained experience,
Moniterra can establish, extend or check Surface and
Underground Geodetic Networks of high accuracy in
short time and finance terms.
