The Mittellandkanal (MLK) is a federal waterway and with a length of 325,3 kilometres the longest canal in Germany. Regarding Europe the MLK establishes together with the German canal network a connection among the Netherlands, Belgium, France and Switzerland on the one side and Poland and Czech Republic on the other side. In the course of expanding the east-west connecting inland waterways (project No. 17 "Verkehrsprojekte Deutsche Einheit") the new overfly Elbeu including the expansion of the Mittellandkanal from MLK-km 315,15 to 318,45 is presently being built. Because of the bypass especially built for this construction work this represents a special project in infrastructure planning. The report shows the tasks and requirements of this outstanding project which represents as well in planning as in completion unique challenges for all parties involved.

The grounds of the Naval Operations School between the bends in the River Geeste in Bremerhaven extend right up to the riverbanks on the northern, southern and western sides. After 80 years the sheet piling on the southern and western banks has become so badly corroded that repairing the wall would be uneconomic. Permission for the construction of a replacement wall was granted in February 2011. This article describes the boundary conditions for the design and construction work, especially the influence of the soft soils and groundwater situation so typical of this locality. The only answer to the abrupt change in level between the school grounds and the river is a heavyweight, combined sheet pile structure with piles up to 33 m long. Despite this, at most only the top 7.60 m of the wall is visible. The article also looks at the restrictions on site noise emissions laid down by the authorities. © 2013 Ernst & Sohn Verlag für Architektur und technische Wissenschaften GmbH & Co. KG, Berlin.

Bendorf In the course of the renewal of its bank reinforcement, the Rhine port of Bendorf will be developed to a modern and efficient inland port. New sheet piling walls will be built for a length of 430 m, and the water depth in the harbour will be increased. A new storage area of 12,000 m 2 will then be protected even at the highest water levels. The situation for tankers will be improved by the erection of new steel piles Copyright © 2012 Ernst & Sohn Verlag für Architektur und technische Wissenschaften GmbH & Co. KG, Berlin.

The Rhine represents Germany's most important inland waterway by far. In order to ensure a safe and smooth ship traffic it is essential to create suitable basic conditions for the stationary ship traffic as well as for the active ship traffic. Insufficient berths are available nowadays, due to Rhine shipping's evolution in fleet structure. Furthermore there is a lack of former berths. The Federal Water and Shipping Administration is planning new constructions as well as the reconstruction of further and existing berths. Thus, 14 berths emerge at the Upper and Middle Rhine. Each one has a capacity for 2 until 12 ships and is located on a route of 290 km between Iffezheim and Brohl. Initial improvement was already achieved by the construction of berths in Iffezheim, Sondernheim and Koblenz-Wallersheim. Further 11 construction projects will follow within the next years. © 2014 Ernst & Sohn Verlag für Architektur und technische Wissenschaften GmbH & Co. KG, Berlin.

After completion of the 2nd Strelasundquerung, including the transport connection to the motorways A1, A11 and A20, the isle of Rügen will be quickly and comfortable accessible. The construction of the B 96n on Rügen is required in order to handle the in- and outbound traffic. Due to the new construction of the 485 meter trough construction 2852-08, the B 96n crosses the railway line 6321 without changing height above terrain level. The construction has been completed in 2014. The report is based on the building process and the geotechnical planning challenge concerning the implementation and the economical optimization of the excavation pit. Both refer to the tender planning as well as to the detailed engineering. © 2014 Ernst & Sohn Verlag für Architektur und technische Wissenschaften GmbH & Co. KG, Berlin.

Grouted joints in Monopile substructures are exposed to high cyclic loading conditions. During maintenance work, vertical settlements in grouted joints with plain steel surfaces have been detected. It became apparent that applied design methods did not represent properly the physical behavior of the connections. Based on theoretical and experimental investigations, this paper presents discovered reasons and discusses the design driving parameters.

In today's terms, we would place a gasometer in the category of infrastructure projects. They were used to store gas. From 1900 onwards the English Imperial Continental Gas-Association was erecting the gasworks Mariendorf with the gasometer that is described here. When natural gasoline was used for supply, the gasworks was closed and dismantled. Some of the buildings were listed also for example the guide rail steel structure of the gasometer. Over the last 100 years the corrosion prevention was merely maintained through over-coating. The now advanced corrosion requires an overhaul. The preparation of the surface is not feasible with grid-blasting, because of structural and emission related issues. Instead the surfaces are being stripped with mechanically driven tools. The focus of this essay is the description of this rather unusual method. © 2013 Ernst & Sohn Verlag für Architektur und technische Wissenschaften GmbH & Co. KG, Berlin.
