PLASTERS
In the basement (1st floor) and partly on the 2nd and 3rd floors, the grooves in the plasters needed for the installation of wiring and electronic security system are being repaired. Non-authentic plaster is being removed on the outside after the secondarily made openings and in the grooves made for various types of installations (e.g. electric) made in the 1980’s. The restoration of the authentic smoothed cement plaster is being finalized in the air-conditioning spaces.
METAL ELEMENTS
The mechanical cleaning of steel windows in the housekeeper’s flat was finalized (3rd floor) and their frames were provided with prime anti-rust coating. At the end of the month, the restoration and renovation of the ash lift mechanical equipment in the boiler room, which was not dismantled, was finalized (1st floor).
In the steel doors with glass glazing a sealing was uncovered in the peripheral groove and a part of the sealing was removed in order to perform a material analysis.
The survey into the internal air conditioning space using a camera robot identified that there are wooden louvers in the air conditioning pipe. Both original hot-air heat exchangers were dismantled in the air conditioning chambers on the 1st floor and transported to the restorer’s workshops.
At the end of March, the unauthentic glazing was removed in the southwestern glazed wall of the main living room (2nd floor) and the restorers started mechanical cleaning of the steel framework structure of the large-size windows. They also dismantled metal awnings, which were transported to workshops to be renovated and to have the structure reinforced as in the future it will have to withstand side wind pressure. The restorers also mechanically cleaned the steel supporting columns and air conditioning pipes on the technical floor (1st floor). In the main living room (2nd floor) they mechanically cleaned the upper surfaces of the steel joists over the 1st floor, which were provided with the prime anti-rust coating and an adhesive bridge before applying the re-profiling mixture.
OTHER WORK
Installation of the security system and the installation of the central heating system continues on the 2nd and 3rd floors.
The existing travertine and sandstone elements are sorted out on site and ready to be transported to the restorer’s workshops.
Excavation work for the last foundation wells under the garden terrace continues.
Unauthentic layers (concrete screed, heat insulation–polystyrene and damp insulation in the form of asphalt strips) were removed from under previously removed large-size terrazzo tiles on the entrance and upper terraces (3rd floor).
Installation of the suction pipes of the electronic fire system was finalized at the foot of the supporting wall, the so-called tunnel (2nd floor).
Installation of steel scaffolds was completed along the southwestern and southeastern of the house façade for the follow-up work on the façade, restoration of the steel glazed wall and awnings.
