TRIPOLI INTERNATIONAL AIRPORT ROAD’S (TIAR) NORTH EXTENSION
For the purpose of connecting the central part of the city of Tripoli with the international airport “Tripoli”, the tunnel design on the road section that passes through a residential area of the city was planned (chainage from km 21+800.00 to km 25+100.00).
For designing purposes, geodetic surveying was carried out in order to unify the results on site and in the cadastre of utilities and underground installations. Also, surveying results were used to create the digital terrain model (DTM), an authentic terrain configuration layout.
Prior to the commencement of the land surveying, it was necessary to prepare precise survey network, which would, later on, be used for geodetic works while carrying out construction works. Survey network was stabilized with visible concrete monuments and for every point a description of the position was done, in order to make it easier to be found on the field. Coordinates (X, Y) were determined with GPS method – Statics, with known trigonometric points. Elevations were measured by using digital level from known benchmarks.
The location was surveyed by using GPS method Real Time Kinematic (RTK).
Geodetic documentation was prepared, where all measured and calculated data was presented.
