A 3.10 m high platform made of glue beams will first be erected on the high terrace.
The helpful friends from Russia bend the rebars into position.
In two stages, first the base slab, then the one meter thick column is concreted.
Last smooth coat on the upper edge of the 1.6m high concrete pier.
Ready dried concrete pillar with 3x3m base plate. As for a railroad bridge.
The steel column comes in two parts from the truck crane. Here is the galvanized lower cone with a base diameter of one meter.
On top comes the upper cone with 60cm base diameter, black powder coated. It really needs to be 100% stable for pin-point stars.
Now the assembly of the observatory on the platform can begin. The base is double grooved wooden panels, 44 mm thick.
Finalizing the roll-off roof construction.
Long distance view to the south towards the Alps (drone view), the observatory is almost finished.
The mighty column has a diameter of one meter at the base. It is almost five meters high with the concrete base.
The cladding of the roof with additional sheet metal panels makes the observatory winterproof.
Except for the missing railings, the observatory building is now finalized. Provisionally, the weather station has also been installed.
The entrance here is through a magnetically secured sliding door. The specialist companies and component manufacturers involved have received tributes on my signs.
