A new bridge for overpassing the A3 freeway was built at the Offenbach junction. There were a total of three excavation pits for this new construction.
A new bridge was built on the A3 autobahn near the Offenbach junction for the replacement of the autobahn overpass. For this new construction, a total of three excavation pits were required in axes 10, 20 and 30, which were constructed with sheet pile sections from thyssenkrupp Infrastructure.
The challenge here lay not so much in the supply, but rather in an ambitiously short time window from ordering the material to delivery. The customer's wish was to complete the excavation pits before the Christmas holidays.
Around 360 tons of sheet pile sections tkL 606 and 607 up to 15 meters in length, including seals and corner structures, were made available to the construction site for axes 10 and 30 in a period of less than two weeks from the order. Part of the material was in stock at the warehouse in Schaafheim, while another part of the sections had to be initially prepared at the plant in Ostrava in the Czech Republic, delivered and later processed at the warehouse.
The first delivery date was to be on December 9, 2020, but could be made as early as December 7. The last delivery was made on December 16. All in all, just-in-time deliveries took only a good week and a half and the excavation pits were completed as requested. In March 2021, the last 100 tons of tkL 605 for axis 20 were finally delivered on schedule.
