Main bridge inspection in accordance with DIN 1076 of the city centre bridge in the course of the four-lane motorway B 49 over a length of approx. 950 m. The structure was built in the 1980’s using prestressed concrete and crosses several railway tracks, intersections, large car parks and the river Dill.
Main structural inspection of a three-span, approx. 115-year-old concrete bridge in Dausenau (river Lahn), which connects the neighborhood on the hillside across two tracks. Due to the poor condition of the structure, the road bridge over the railway tracks will be replaced by a concrete slab construction on sheet pile abutments.
Construction of a new production building in steel and solid construction. Construction of tank foundations in liquid-tight concrete troughs and various pipe bridges in steel construction.
New construction of the Sandberg flyover with noise barrier and new construction of a rainwater retention basin as part of the traffic upgrading and four-lane expansion of the B 266 motorway between the Wißkirchen junction (motorway A 1) and the Mechernich-Roggendorf bypass.
Construction of two pumping stations for pumping the wastewater from the new Terminal 3 to the existing wastewater treatment plant. Due to high groundwater levels and a very permeable subsoil, extensive special civil engineering work was necessary. Sheet piling was used in conjunction with a back-anchored underwater concrete base.
As part of the Emscher renaturation, extensive plans were drawn up for both the excavation pits and the engineering structures for the stormwater overflow basin at Gladbecker Straße, the storage canal at Berger Feld and the stormwater overflow basins at Sutum and Springbach .
Construction of an overpass of the L 354n road over the river Niers near Mönchengladbach. In the area of a peat bog. The ramps have to be founded on driven piles in a grid of approx. 2 x 2 metres with a pile length of 8 metres. The bridge itself is founded as a single-span structure on in-situ concrete piles.
