The existing day-care centre on the northern edge of Holzkirchen, in Erich-Kästner-Strasse, is to be expanded
become. The extension will be built as a two-storey extension with a staggered gable roof and a
Partial basement built for technical rooms and storage.
Outside, the after-school care area will have two courtyard areas and a garden area with a noise barrier
to Rosenheimerstraße. The construction of the noise barrier is carried out as a separate construction measure.
The soil conditions require special measures in the foundation of the structure.
As a preliminary measure, seepage systems will be built on the property. These must not be run over
Become.
During the entire construction period, the operation of the existing kindergarten will take place.
The structure is to be erected in 3 construction phases. The staggered execution times are shown in the
construction schedule and must be taken into account.
The building will have a partial basement. The surfaces of the wooden components in the interior are finished surfaces
and will not be treated further. They must be protected against contamination and damage.
The energy objective requires a conscientious way of working on the part of all those involved in the construction.
In particular, this means avoiding structural thermal bridges, clean working and a high
Measure of the airtightness of the building envelope.
Screeds as cement screeds
- according to DIN 18560 ZE 30
- Minimum thicknesses according to specifications from floor structures are constant over the entire surface, even with
Sloping execution.
Insulating materials
- Only CFCs (fuorchlorofluorocarbons) free products.
- SVHC-free
- The provisions of RAL-CU 132 "Thermal insulation materials and suspended ceilings" must be observed.
Appropriate proof of quality must be provided.
Trennfolien
- as PE film 0.2 mm
Floors
- Screeds are divided with shrinkage joints (see joint plans)
- Shrinkage joints in longer rooms must be doweled and encapsulated with synthetic resin.
Floating screeds must be secured against shearing at expansion joints and separations.
- Building services cables or similar laid on the bare ceiling are integrated into the screed structure in such a way
to incorporate that
- There are no airborne and structure-borne sound transmissions
- there are no weakening of the screed
- there are no cavities in the insulating material layer (possibly filling with perlite)
Insulating edge strips at the connection are obligatory
- Screed formation for threshold-free floor coverings, unless otherwise stated.
- Screed surface ready for subsequent flooring work
- Flat surface, possibly by filling, even in several operations. Flatness measurements
are to be carried out and recorded.21
- Protection against too rapid and irregular drying of the screed by foil layer min. 3
Days
- After that: protection against excessive heat and drafts.
