The challenge

After completing the first part of the fire safety concept of 2009-2012 hoyos architekten is engaged to continue implementing the concept, as well as exchanging the heating system from steam to water. This project is the crucial part of the overall ecological and sustainable refurbishment of the city centre campus of the Technical University of Munich. The listed building was designed in 1949 by Robert Vorhoelzer.


The solution

The fire prevention system is implemented by building two internal staircases as second escape route from the lecture halls in the north and south wing. All building doors are fitted with fire safety characteristics, the whole book stack room with a sprinkler system, the hallways in the basement are upgraded to first and second escape routes and least all façade windows are toughened against fire flashovers at the firewall borders.

A main issue during the ongoing university activities is the location of the construction facilities including the supply and waste chain. The restructuring of heating and water pipes is organized like a vertical moving work site, subdivided into 6 sections. Fire safety doors are replaced floor by floor downwards. All other measures are being integrated into the main renovation according to the needs of the occupiers, offering them a detailed 14-day-outlook of noise and dust emissions in the affected parts of the building. There are temporary premises in modular construction located in the inner courtyard.

The refurbishment of the lecture hall on the second floor offers a new design with a roof lantern in mullion-transom construction and is completed with totally new techniques for media, sound and light.

hoyos architekten handles this very complex construction project with a close collaboration between the technical contractors, starting already during the schematic design phase and even closer during the execution. A continuous on-site presence during ongoing campus activity is the clue to a stringent and successful schedule.
