The initial steel components of the second construction phase were completely pre-assembled in the form station. Sections 1 to 5 have been placed on the completed staging frame.
In the next step, the interior diagonal sections were installed. Since then, the welding work on the entire superstructure has been in full swing.
By the end of the year, the lateral cantilevers will be assembled before the entire first increment cycle is moved in February.
Steel construction is nearing completion on the north bridge structure.
The deck coating has already been applied on more than half the bridge.
The welding work of the second half is almost complete and the corrosion protection work is in full swing.
After completion of the steel construction, the later roadway slab still needs a layer of concrete before it can be moved via SPMTs into its final position in spring.
In another night operation, the last steel components were assembled on the A45 Dorlar viaduct.
The 650t crawler crane was once again deployed. It successfully lifted the end cross girder in axis 12 and the four corresponding longitudinal girders.
Assembly of the supply mast began in mid-October.
First came the base point, followed by placement of the initial four sections on top of each other. Afterwards, the sections are welded together before assembly of additional sections continues.
At our building construction site, last week marked the beginning of the next-to-last and largest construction phase.
It involves the showroom and loading building with total tonnage of 160 tons.
During the night from Tuesday to Wednesday, another section of the Dorlar viaduct of A45 motorway was erected.
Using a 650t crawler crane, the supporting cross beam was successfully lifted into axis 11.
The installation team only had a time window of four hours for the total operation, as the adjacent rail traffic was blocked during this time period.
In the two days that followed, the four longitudinal girders extending across the Lahn River were also lifted.
The 2nd construction phase of the Heidingsfeld motorway viaduct was launched at the beginning of this week.
Construction began with the build-up of the foundations in the form station, on which the first steel components are to be laid in beginning of November.
By the end of August, the pad was welded on a pre-assembly surface. After these tasks were completed, the pad was successfully moved to its final position on September 11, 2018 and subsequently de-stacked onto the concrete slab. The final construction phase is currently underway.
The installation of the supply mast will follow in mid-October.
On the first weekend in September, 8 steel girders of the new bridge structure were lifted over the A1 motorway near Cologne in two night operations.
The end cross girder (section 1) and section 2 of the new Linz bypass bridges arrived on schedule at the Linz construction site on August 25, 2018.
