Embankment Compaction Management System-TE Nav | Automated Measurement Systems

The Ministry of Land, Infrastructure, Transport and Tourism (MLIT) has compiled ''the Guidelines for Computerized Construction Management of Embankment Compaction Using Total Stations and GPS (Draft)'', positioning it as the third management method following the conventional sand replacement and RI gauge methods. TE Nav supports both total stations and GPS, assisting in computerized construction for river works, road earthworks, and paving projects.
