Task:
In the run-up to the planning, a concept and a cost estimate were drawn up. The inventory was examined with the help of component openings and inventory documents.
An essential part of the commissioning is the planning of the site logistics and the necessary scaffolding and lifting tools and protective measures. From the concept, a preferred variant has already emerged.
The entire roof structure is to be dismantled as part of the renovation measures to the raw ceiling. The insulation and sealing materials may possibly contain pollutants. The existing flaps, lids and Attikableche should be used again if possible. The penetrations must be renewed in coordination with the building services. The demolition measures must be done as far as possible low noise and dust. The removal can only take place via the scaffold tower.
The thermal insulation and the seal must be rescheduled and executed according to the current standard. To this end, the changed requirements of the ENEV must be observed and implemented.
The sealing joints have to be redesigned and made DIN-compliant, respecting the existing architectural design.
The processes and emergency processes must be re-planned and dimensioned according to today's standards.
In the original design, a tile covering was planned for the entire roof. This should now be implemented.
The openings in the roof surfaces should be permanently protected with stainless steel mesh. The existing protection concept must be checked and, if necessary, adapted to today's requirements.
The lightning protection system must be dismantled and reassembled after the refurbishment.
