REVITALIZATION OF RESIDENTIAL AND COMMERCIAL BUILDING IN GÖTTINGEN

Artis Göt­tin­gen GmbH, as the cli­ent and part of the GETEC Immo­bi­lien Group, is car­ry­ing out a revi­ta­liza­tion of the resi­den­tial and com­mer­cial buil­ding Ween­der Str. 80–82 in 37073 Göt­tin­gen. As part of this pro­ject, repair and moder­niza­tion work is being car­ried out on the buil­ding in the cen­ter of Göt­tin­gen. LPI Inge­nieur­ge­sell­schaft mbH was com­mis­sio­ned with the plan­ning of the rein­forced con­crete repairs, the pre­pa­ra­tion of a cata­log of mea­su­res and the imple­men­ta­tion of sup­ple­men­tary struc­tu­ral dia­gno­stic inves­ti­ga­ti­ons, such as rein­forced con­crete repairs to the cei­lings and beams on the indi­vi­dual flo­ors and chlo­ride repairs to the under­ground car park and some of the exte­rior components. 

The buil­ding was in a gut­ted shell con­di­tion and has 4 upper flo­ors, a first floor and a base­ment. The base­ment is used as an under­ground par­king garage, among other things, and has an access ramp. The buil­ding was con­s­truc­ted using rein­forced con­crete. The walls, columns, beams, cei­lings and floor were mainly made of in-situ concrete. 

In June 2023, ARGE Ween­der Straße 80–82, con­sis­ting of the com­pa­nies Scadock&Hofmann GmbH Co. KG, AUGUST REINERS Bau­un­ter­neh­mung GmbH and BARG GmbH & Co. KG, was com­mis­sio­ned with the fol­lo­wing services: 

  • Con­s­truc­tion site equip­ment and pro­tec­tive measures

  • Seal­ing of cei­ling ope­nings of various dimen­si­ons with con­crete / grou­ting con­crete, inclu­ding sub­strate pre­pa­ra­tion, in some cases with the instal­la­tion of struc­tu­ral reinforcement 
  • Sur­face pre­pa­ra­tion of the sub­strate on the under­side of the cei­ling and the under­side of the beams for the appli­ca­tion of a spray mortar to increase the con­crete cover by blas­ting with a solid blas­ting agent
  • Exten­sive appli­ca­tion of a spray mortar to the under­side of the cei­ling and the under­side of the beams to increase the con­crete cover in accordance with the fire pro­tec­tion specifications

In the course of the work, the con­tract was exten­ded on the 4th floor and in Decem­ber 2023 the con­tract for the reno­va­tion of the under­ground par­king garage was awarded, which is to be com­ple­ted by the end of May 2024.
