The University of Duisburg-Essen (client) invites tenders for cleaning services in buildings on the Essen campus and their outdoor properties. The cleaning services include maintenance cleaning, the provision of additional service staff and, if necessary, the implementation of special cleaning

Areas of buildings T and S. The T-Group consists of buildings T01, T02 and T03. Here is the headquarters of the administration in Essen, so there is mainly office space and meeting rooms here. The S-Group consists of buildings S03, S04, S05, S05Pik, S06, S07 and S08. Building S04 is a lecture hall centre. Building S06 is mainly used by the Faculty of Education. Therefore, the area to be cleaned consists largely of offices and classrooms.

I. Schützenbahn.

This includes the buildings S-A, S-E, S-GW, S-H, S-L, S-M and S-R. The main users are the Faculties of Chemistry and Economics. There is a large server room in building S-H. The building S-M is the seat of the university sports including the areas of the university sports club.

The S-AM building, which is also located in this area, is used by the Studierendenwerk and is not part of the tender. Also marked on the map is the Rabbi's House, which is home to the Salomon Steinheim Institute.

II. Sportcampus Gladbecker Straße and Leimkugelstraße

The sports campus of the UDE is located on Gladbecker Straße. It consists of two sports halls, the GLA-SH and GLA-ZH buildings. For safety reasons, special care must be taken when cleaning the hall floors. There is also the GLA-SP administration building with office and classroom space, the small GLA-P pavilion and the GLA-WDW residential building used as storage space.

III. Zollverein

The Erich L. Hahn Institute is located on the grounds of the Zollverein World Heritage Site

The R-Group consists of the structurally connected buildings R09, R11, R12, and R13 as well as the free-standing buildings R10 and R14. Buildings R09, R11 and R12 are mainly occupied by the Faculties of Humanities and Economics. In addition to a large number of offices and classrooms, the library is located in building R11 and the University Printing Center in R12. Two day-care centres are also operated in the building. Parts of the space are also occupied by the Studierendenwerk, which operates a cafeteria here. These areas are not part of the cleaning contract. Building R14 is a separate lecture hall building.

Building R10 is the headquarters of the technical building management and the central warehouse. There are also workshops here.

The V-Group consists of buildings V13, V15 and V17. These buildings are all structurally connected and are used equally by faculties and university institutions. Therefore, the area to be cleaned consists largely of offices and classrooms.

Building V15 is currently almost empty due to a construction project that is expected to last until 2025. Some major construction work is also taking place in buildings R09 and R12.

Lot 4 comprises the outdoor properties Weststadttürme (WST), Weststadtcarreè (WSC), Altendorfer Str. 5-9 (A) as well as the property in the botanical garden of the Gruga. The buildings WST, WSC and A are within walking distance of each other on Altendorfer Straße and Limbecker Platz. The main users are the university administration and some chairs, so there is mainly office space and meeting rooms. The WSC is home to the faculties of mathematics and economics. Here, too, a large part of the surfaces to be cleaned consists of office space. In the building on Altendorfer Straße, on the other hand, there are almost exclusively teaching areas, including the university's PC hall.

In the Botanical Garden of the Gruga, the Faculty of Biology occupies several buildings. Most of the area is occupied by greenhouses, which are not part of this cleaning contract. The cleaning job covers only a small proportion of the total area. The cleaning cycle here differs from that for other surfaces at the UDE.

Lot 3 comprises the Institute for Advanced Study in the Humanities (KWI) at Goethestrasse 31 in Essen. This is an interdisciplinary research college for the humanities and cultural studies. As an inter-university college of the Ruhr University Bochum, the Technical University of Dortmund and the University of Duisburg-Essen, the institute works together with the scientists of its sponsoring universities and with other partners in NRW and at home and abroad. In addition to the research work, lectures for the public are often held here.

In addition, there are seven small living areas in the KWI building, which are rented out to visiting scholars both on a short-term basis and for longer periods of time. These are also part of the cleaning contract, whereby in addition to regular cleaning in the event of a change of tenant, a basic cleaning must also be carried out.
