Neubau des Schulgebäudes Severinswall in Köln – Integrierte Gesamtschule Innenstadt (IGIS)

The new building for the inner city comprehensive school (igis) on Severinswall in Cologne created space for the implementation of new pedagogical space and teaching concepts in so-called clusters. A double gymnasium was also integrated into the building. The most striking design element of the new building, designed by Molestina Architects, are the imposing barrel roofs. They look like waves on the outside and like vaulted ceilings on the top floor. Climate protection and energy efficiency were an essential part of the development and realization of the new building. This also includes the use of district heating, photovoltaic systems to generate electricity and solar shading systems linked to the outside temperature and heat recovery via the ventilation systems. The building was constructed according to passive house standards. The best possible conditions have been created for quality of stay and learning in terms of temperature control, indoor air, ideal lighting and sound insulation.

The project was planned and implemented by a total contractor (TU) on behalf of Gebäudewirtschaft Köln (GWK). Alpha IC was commissioned by GWK as commissioning manager to manage and control the commissioning process. The commissioning manager acts as an external project manager for the client (GWK) and acts on its behalf. The client assigns him powers of instruction and authority over the other project participants. His tasks include ensuring that the client's requirements are met. To this end, the commissioning manager continuously monitors the IBM-relevant processes, e.g. by checking documents, carrying out IBM control appointments and site inspections. Any deviations identified are pointed out and the necessary measures for rectification are requested from the TU. 

The aim of the IBM is to consider all technical systems of the various trades as a closed technical system and to carry out a comprehensive functional test across all trades in order to prove the required functionality of the entire system. A further objective is to implement the documentation and data maintenance requirements for the City of Cologne's CAFM program to

Commissioning management ensures that the planned characteristics of building operation are realized. It leads to risk minimization and is a relevant component of the economical use of resources during subsequent operation.
