The Landestalsperrenverwaltung of the Free State of Saxony, operation Zwickauer Mulde / Upper White Elster, intends to land a terrestrial survey of the white magpie about 36 km in length, divided into three lots to award.

Instigation:

The Weiße Elster is to be examined in the area between river km 167 + 800 to 204 + 011 by means of model-based water level calculation for the preparation of flood risk and flood risk maps as well as for the preparation of the flood risk management plan. An engineering firm - hereinafter referred to as a modeler - has already been commissioned for the modeling and map production.

As part of the basic data analysis, a section of watercourse, structure and breakline measurement in the study area is required, the content of which is described below and is the subject of the present inquiry.

The primary objective of the survey is the preparation of a baseline plan (digital position and height plan) for the water level calculation, which focuses on the hydraulically relevant structures of the water hose and consists of height-adjusted, cleanly connected line elements and possibly points

The entire processing or investigation area extends along the Weiße Elster from river km 167 + 800 to 204 + 011. The processing area begins north of the city Elsterberg, below the local situation Nosswitz) and ends in the area of the local situation Magwitz, immediately below the dam Pirk.

The contract shall include all services required to complete the work described in the AST above and described in detail below, surveying main waters, tributaries, hydraulic rupture edges (including the sub-items mentioned) and the creation of photographic documentation. The surveying recordings must be made according to the requirements of the requirements stated in this task.

The works to be awarded consist essentially of the inclusion of transverse profiles, breaklines and structures on and in the water. From the buildings, the flood defenses and the waters are also maps to make.

In order to be able to check compliance with the prescribed quality standards, a test data set must be handed over to the modelers and the commissioned modeler (digital) for the technical and formal (current CAD guideline of the LTV) three to four weeks after the start of the surveying activity. The files in Attachment 5 serve as templates for this purpose. The examination of the data is carried out as quickly as possible. As a result, if necessary, a joint on-site meeting is carried out in order to rule out incorrect work executions for the further surveying. These services of the creation and transfer of the test data set and the necessary coordination dates, if necessary, are to be included in the surveying services.

The measured and evaluated data of the area must be submitted in advance digitally to the modeler and to the LTV for examination (reading version test data record). The data, which are used to check for equal height connection of the measured horizons, are to be transferred as a DWG file exclusively with height-assigned points and lines. After the test routine has been carried out, the data will be returned to the surveyor with a test report, if necessary. The data will be confirmed only if there is a positive result. All services until the confirmation of the data are to be offered and calculated as a basic service within the scope of the survey. After confirming the data, they must be converted into the specified CAD format of the LTV.

The current CAD and GIS guidelines of LTV (see www.talsperren-sachsen.de - Specialist information - Information for contractors) must be applied and adhered to.
