Prior knowledge

BūvZ6045, Geodetic Support System I

Course abstract

The aim of the course is to familiarize students with the significance and organization of the geodetic reference system in the construction and operation process.
Students learn engineering geodetic research of construction sites and tracks, for the design of various engineering structures, about the methodology of designing a construction project. Long - term measurements of deformations.
Knowledge of high-precision measurements of project design and construction procedures is gained, using both classical and special tools and devices; as well as to perform executive measurements and compile their documentation.

Learning outcomes and their assessment

Knows the types of geodetic networks, their construction methods taking into account the intended network tasks, accuracy characteristics and the nature of the terrain. Knows and evaluates the factors influencing geodetic measurements. – exam
Is able to apply knowledge of geodetic survey of various engineering structures, their project designation in the area and geodetic supervision of construction. - practical works

Is able to apply the acquired knowledge to the development of a geodetic control system, substantiating the necessary use of resources and finances. – practical works
