The second Moselle lock presented a challenging construction project, but working in cooperation, PERI supported the construction site managers from Hochtief Infrastructure GmbH with a project-specific formwork and scaffolding concept, just-in-time deliveries of accurately pre-fabricated formwork elements as well as continuous on-site support. The Moselle lock in the south of Trier is currently being extensively extended and also features an additional, highly efficient lock chamber. Seven further projects of this kind between Koblenz and Trier are scheduled for completion. The lock chamber is being constructed parallel to the 170 m long existing lock, and is 216 m long, 12.70 m high and has a usable width of 12.60 m. Including intake and outlet structures, the new, second lock measures a total of 312 m. Filling and emptying take place using longitudinal channels which are arranged on both sides together with transverse-positioned branch channels.
The reinforced concrete structure with massive component dimensions and a high degree of reinforcement was realized at a depth of 15 m within bored pile walls. The time-consuming structural work was completed in autumn 2017. After completion of the hydraulic steelwork and mechanical engineering works, lock operations are to be started in 2018. In total, around 45,000 m³ of concrete were processed on the large-scale construction site in just under 1.5 years.
Challenging large-scale construction site, the formwork and reinforcement work in particular presented a major challenge. In order to comply with the required accuracies along with the short construction schedule, a formwork concept with a high level of prefabrication was selected. PERI’s formwork assembly team of experts produced and delivered the formwork elements to the jobsite ready for use – exactly matching construction site requirements in terms of quantity and time.
Reliable support throughout all project phases during the construction of the Moselle Lock in Trier, a PERI project coordinator supported the site management in all technical, commercial and logistical aspects regarding the coordination of the planning and installation work as well as ensuring punctual supply of materials. Furthermore, PERI supervisors briefed the site personnel, as and when required, on the correct and safe handling of the systems and special formwork being used.
