Structural design in the context of the modernization of the dentist's house

It is intended to modernize the administrative building of the KZBV, Universitätsstraße 73 in 50193 Cologne. The planned measures include:

- a functional revitalization of the utilization structure (transfer of the kitchen from the 4th floor to the ground floor and conversion of the vacant space as offices),

- upgrading and optimizing office space,

- modernization of the meeting room as a central meeting area with a mobile partition wall system,

- Installation of air conditioning and possibly ventilation technology in the entire building, possibly dismantling of existing refrigeration technology in some areas,

- reviewing and, if necessary, modernizing the existing building services (heating, plumbing, electrical, refrigeration),

- modernization of sanitary facilities,

- approval of a uniform fire protection concept for the entire building,

- Building physics examination of the building stock as a basis for further planning (heat protection, sound insulation, room acoustics),

- optimization of basement rooms,

- renewal of the cooling equipment and storerooms in the cellar belonging to the company kitchen,

- in phases 1-4, the entire building should be planned,

- the preliminary design (performance phase 2) with the cost estimate according to DIN 276 required as a basic service is to be provided by the end of March 2020, as the technical committees of the KZBV will make further decisions in April,

- Implementation from service phase 5 on a construction phase basis, probably during operation.

The subject matter is structural design services within the meaning of §§ 49 ff. HOAI. As a basis for further planning, the building will be subjected to a condition analysis. In the process, isolated damage (cracks) and the load-bearing capacity of existing components in areas with special load requirements through use (libraries, servers, etc.) and building services (air conditioning and ventilation equipment on the roofs) are to be investigated. In addition, the cargo reserves of the existing extension, where the meeting room is located, will be identified in order to check for interim use as an alternative area for the offices to be converted and for the installation of a mobile partition system.

In addition to the planning services in the service phases 1 to 9 gem. §§ 49 ff. HOAI are to provide further special services. These include the examination of the existing static documents and load assumptions for completeness, an inspection of the building to determine current damage formation and determination of the resulting remedial needs and the exploration of the building fabric of the attached meeting room to determine the carrying capacity of load reserves. If the applicant considers further special services to be necessary, they must be included in the offer and offered.

The commissioning of the planning services takes place gradually, in the first stage for the service phases 1 to 4, that is, until the preparation of the design template as a basis for the necessary committees decisions of the client. The commissioning of the further service phases takes place in dependence of these committee decisions. There is no legal claim to the commissioning of further service phases according to HOAI.
