Photo documentation of the construction work: Ronald Seiffert.
The completed construction site is taken over by the Senate Department for Environment, Transport and Climate Protection and subsequently handed over to the cemetery administration of the district Treptow-Köpenick. The acting persons can be seen in the picture (from left to right): Mrs. Gansauge (cemetery administration), Mr. Gruber (struber_gruber), Mr. Fittkau (fittkau metallgestaltung), Mr. Klaus (test engineer), Mrs. Struber (struber_gruber) , Mrs. Behrend, Mrs. Gutte (senate administration), Mr. Gößling (cemetery administration).

Assembly of the glass panels! The heaviest panel weighed 799.91 kg.
The grave border is completed
22 and 23 June:
Placement of the water-bound surface.
Meanwhile, at the glassworks in Nossen, on 2 June:
The team is working with great care on the centrepiece of the memorial. The challenge of making the glass panels monochrome and opaque while at the same time allowing the godparents’ lettering to appear as a light recess in the dark green surfaces was met with the best possible quality.
On 2 June, the first three panels could be taken down.
17 May to 7 June 2021
Preparation of the urn grave field for planting with vinca minor alba. First, the vegetation as well as kerbstones and some stepping stones around the memorial stone from the 1950s erected during the GDR era will be removed. The turf is peeled off and filled with soil to the desired level. After the formation of the subgrade, vinca minor alba, small periwinkle, is planted.
7 – 28 May
The substructure for the wall of the names is assembled: Stainless steel plates are aligned horizontally on the concrete, and aluminium profiles are placed on top of them to hold the glass panes. These aluminium profiles also hold the bronze parts that will later frame the glass panes.
30 April: The concrete construction is completed, the formwork can be dismantled and the company leaves the construction site.
23 to 28 April: The reinforcement is installed, tested and approved. After that, the reinforced concrete foundation can be built.
20-21 April: Part of the foundations are concreted: on the one hand, the frame around the urn fields U1 and U2 is built, on the other hand, the supports for the reinforced concrete foundation of the glass wall are erected.
At this point, we would like to thank Ronald Seiffert from the Altglienicke Citizens’ Association, who documented the entire construction period photographically, had conversations with the workers and captured their work in a very coherent way.
16 April: Root protection is taken very seriously in Berlin and makes it necessary to dig by hand under the crowns of trees, to protect and enclose stronger roots so that the tree is not weakened.
15 April: The excavation for the foundations is completed.
No sooner does the excavation for the foundations begin than some old objects are dug up. After a few days, urns come to light: this means a construction stop, the urns have to be examined, it turns out they date back to the 50s and 60s. Subsequently, all the urns are recovered and buried elsewhere in the cemetery.
Work on the redesign began in the 12th calendar week, on 23 March, with the excavation for the necessary foundations. The glass wall with the names of the victims needs a foundation about 2m wide, and the border of the bronze urn grave field also rests on a concrete border.
