Exploration drilling in the weir posts and radar measurements to explore the concrete quality and the management of the steel inserts, Ankerzugversuche, exposure of individual fields on solid construction and their logistical support (as alternate vessel as equipment and other auxiliary equipment), implementation and evaluation of soil mechanics and concrete technology experiments. 4 vertical holes in the weir posts to about 20.00 meters (approx. 80.00 meters), core diameter = 142 mm. Hole through the dam pillars in extension more about 5,00 m (approx. 20.00 meters), core diameter = 100 mm into the ground for the recovery of cored drill. Groups of 4 vertical holes above and below the weir to about 10.00 m (approx. 80.00 meters), core diameter d = 100 mm, made under the river bed from the pontoon. 23 horizontal wells, each approximately 1.60 m depth, hole diameter to 152 mm. 4 Remove the vertical wells after performing all structural inspection as groundwater monitoring wells. 8 fields in solid building expose to assess the steel inserts and close properly. Set including 14 Ankerzugversuche and remove the anchor. WD-tests and borehole scans (optical and hydraulic borehole investigations) to the vertical wells, results evaluated and documented. All building inspections and test specimens recovered are to be evaluated by an expert engineering firm and zufertigen at-a meaningful opinion on the structural condition. The report shall be in accordance with the requirements of the DIN s currently valid. Implementation of the create for the work necessary coordination BaustellV, a SiGe-Plan and all other documents for safety, health and safety and ongoing monitoring.
