Pro­ject descrip­tion:
In Gör­litz, the Free State of Sax­ony is buil­ding the new Sen­cken­berg Cam­pus — a cen­tral buil­ding com­plex for the Sen­cken­berg Museum of Natu­ral History. The new buil­ding will later serve valuable coll­ec­tion, rese­arch and tea­ching pur­po­ses for the aca­de­mic study pro­grams as a branch of the TU Dres­den. The Sen­cken­berg Museum’s admi­nis­tra­tion and work­shops will also be housed at the new loca­tion. A total of 8300 m² of usable space is plan­ned. The entire com­plex com­pri­ses 5 buil­ding sec­tions, some of which are divi­ded into con­nec­ting buil­dings to the exis­ting neigh­bor­ing buil­dings and buil­ding sec­tions in the inner cour­ty­ard. Exis­ting lis­ted and his­to­ric parts of the buil­ding will also be reno­va­ted and inte­gra­ted into the com­plex. The over­all pro­ject is plan­ned to cost around EUR 60 mil­lion and is sche­du­led for com­ple­tion at the end of 2023.

Pro­ject requi­re­ments:
The new buil­ding was plan­ned as a water-imper­meable con­crete struc­ture in accordance with the WU gui­de­line and is clas­si­fied as a high-qua­lity use. The design water level is above the plan­ned floor slab, which is why the con­s­truc­tion must be dimen­sio­ned against pres­sing water. Due to the extre­mely sen­si­tive use of the inte­rior spaces, the requi­re­ment here is for a func­tional design with the hig­hest pos­si­ble level of safety.

Solu­ti­ons:
In order to reduce the risks as far as pos­si­ble, a con­s­truc­tion con­sis­ting of a white tank in com­bi­na­tion with a fresh con­crete com­po­site sys­tem was cho­sen. The choice fell on the inno­va­tive Sika­Proof A+ tech­no­logy, which is cha­rac­te­ri­zed by a hybrid com­po­site with maxi­mum con­s­truc­tion site robust­ness. Thanks to the con­s­truc­tion with a spe­cial TPO-based com­po­site sur­face, the sheets could be ther­mally joi­ned tog­e­ther in the seam area. This seam joi­ning vari­ant is cha­rac­te­ri­zed by maxi­mum safety, robust­ness and relia­bi­lity, which is why the qua­lity of the over­all mea­sure can be signi­fi­cantly increased. In com­bi­na­tion with the Sika­dur-Com­bi­flex TF sys­tem as a mas­king sys­tem for joint seal­ing and tran­si­ti­ons, a com­plete and fully tes­ted over­all sys­tem is pro­vi­ded. Cou­pled with the high-qua­lity exe­cu­tion of the con­s­truc­tion pro­ject by the gene­ral con­trac­tor Hentzsche Bau, Baut­zen, and the cer­ti­fied spe­cia­list instal­ler August Rei­ners Bau­werks­er­hal­tung Wüs­ten­brand, the Sen­cken­berg Cam­pus in Gör­litz is thus opti­mally protected.
