Since the beginning of January, the first construction phase has occurred with the furnishing of the construction site, the dredging in the port basin to a depth of NHN -6.7 meters (6.7 meters below sea level/standard zero), and the dismantling/removal of old elements of the quay at the Helgoland Quay. With the first pile-driving blow, Dr. Bernd Althusmann, Niedersachsen’s Minister for Economic Affairs, Labor, Transport, and Digitization, officially signaled the commencement of construction work at the Alter Vorhafen port section in Wilhelmshaven.
Althusmann: “The ports of Niedersachsen depend on a secure and efficient infrastructure. The modernized Helgoland Quay will fully meet these requirements, especially with regard to the important cargo handling options for coastal protection and rescue operations. I am sure that the restored Helgoland Quay will attract many tourists that want to experience the special flair of Wilhemshaven's South Beach.
During recent years, the Helgoland Quay had only been used to a limited extent for reasons of stability, and will be fully repaired this year, at a cost of around five million Euros. A new corrugated sheet piling wall is placed in front of the 100-meter-long existing sheet piling wall, then anchored and subsequently back-filled. By the end of the year, the quay head will be erected and stairs will be constructed in front of the sheet piling wall. In addition, the new Helgoland Quay will be equipped with fixed ladders, cross poles, head bollards, as well as mooring and berth dolphins.
Completion is scheduled for December of 2019. It is expected that by then, work will have begun on the Wangeroogkai on the opposite side, which will also be renovated.
The construction work was awarded to Ludwig Freytag/TAGU at the end of September 2018.
“For us, this measure is a special digitization project. We have already built the Helgoland Quay. In virtual form. In addition to the 3D construction model, we have a database that also contains information on materials, deadlines, and costs. We can compare this with our partners in real time and we're banking on time and cost savings," explains Holger Banik, Managing Director of Niedersachsen Ports GmbH & Co. KG and of JadeWeserPort Realisierungs GmbH & Co. KG
The project for the restoration of the Helgoland Quay is a pilot measure, i.e. it is the first time that we are applying the program Building Information Modeling (BIM) to a real-life project. BIM is a collaborative work methodology that uses digital models of a building to permanently capture and manage information and data relevant to its life cycle. In addition, such information can be exchanged in transparent communication between all those involved in the construction and in the operation and handed over for further processing.
Between 1877 and 1886, the Helgoland Quay was used as the 1st Entrance to Wilhelmshaven's interior port that was protected from tides, and comprised a usable quay length of some 100 meters.
Due to damage in the quay walls, a back-anchored sheet pile wall was placed in front of the quay walls between 1953 and 1957. In order to counteract corrosion, a corrosion protection system was installed in 1985.
In 2004, a drainage system with drainage and pump shafts and a reinforced concrete beam were installed at the Helgoland Quay. In addition, a partial restoration was performed in 2007 and 2008.
