CONSTRUCTION SURVEYINGAND SETTING OUT TASKS

Construction surveying is essential for the control of any kind of construction process, like tunnels, mines, shafts, bridges, dams, roads, buildings or other structures. The most basic task is to stake out points and markers that serve for guiding the construction of new structures according to the design. Further tasks are the survey of existing conditions of the work site including topography and existing buildings and infrastructure before construction, the verification of the location and dimension of structures during their construction and the as-built survey and documentation after construction.

In underground construction highly-specialized surveying methods and equipment are required to guarantee the surveying performance and accuracy needed.In this field of application, construction surveying often includes the setting out of geometrically highly-complex 3D objects such as portals, banks, foundations, pile walls, vertical and inclined shafts, pipe umbrellas, tunnel niches and cross-cuts, inner shells and frameworks, tunnel floors, carriageways, tracks, drains, boreholes and many more.

FIELD OF APPLICATION:

Through flexible measuring arrangements (e.g. free stationing) we take care for an optimal integration into the construction process and to achieve best synergies, for example with 3D displacement monitoring. Setting out can be performed by our experienced staff or, in

special cases, by site staff when operating our automatic setting out system KRIOS. During and after construction, we check and document the project (e.g. by using our tunnel laser scanner ORTHOS) to assure the quality of the entire construction.

Tunnel and Underground Construction

We offer object-specific setting out and surveying for earthwork and construction of engineering projects such as excavations, embankments, bulkheads, diaphragm walls, piles, foundations, roads and building site installations, open cut excavations, cut-

and-cover constructions, slope protections, disposals, portals, galleries, dams, bridges and other high-rise buildings.For earthwork, we survey the surface, generate elevation models, calculate volumes and masses and provide a reliable base for billing.

GEODATA offers the full range of construction surveying services and equipment, and is a specialist for underground construction survey. We provide experienced surveyors capable to carry out all kinds of engineering survey for construction, working in flexible schedules providing our service on a daily or weekly basis or as continous operations. We use state of the art surveying equipment such as robotic total stations, digital levels and GNSS-sensors and

also produce and offer automatic setting out systems, targets and marking material. All survey data is processed by EUPALINOS, our dedicated software tool for construction surveying. GEODATA offers construction site survey services for all projects, large and small, national and international. One of our core competencies is the execution of total projects, i.e. we see ourselves as a provider of integrated construction site surveys and products.
