Summary
Machine-generated summaryThe buyer requires specialist planning services for building services engineering, equipment group 3 under the HOAI fee structure, covering the replacement of ventilation systems at Bielefeld Brackwede prison in North Rhine-Westphalia. The existing 16 ventilation units no longer meet energy standards and are to be renewed as part of a wider energy refurbishment of the roof and facades of the main building. Works proceed in phases while the prison remains in operation, so the planner must coordinate construction staging, crane locations and structural interventions with the ongoing prison operation. Planning must include interfaces to building automation, which is commissioned separately. Lighting will be converted to LED while cells are vacated.
