Tbilisi Public Service Hall

The Tbilisi Public Service Hall is situated in the central area of the city and it overlooks the Kura river.

The building is made up of 7 volumes that contain offices (each volume is made up of 4 floors located on different levels). These volumes are placed around a "central public square", which is the core of the project, where there is the front office services. Offices are connected to each other by internal footbridges that stretches on different levels.

Volumes and the central public space are towered above by 11 big "petals" that are independent both formally and structurally from the rest of the building. Three of those big petals covers the central space. The petals, different for their geometry and dimension, reaches almost 35 meters and they are supported by a structure of steel pillars with a tree shape, visible, as well as the petals, externally and internally from the building.

Among the petals, that are at different levels, are the glass facades. The main characteristic of these facades is that these have been released completely from the structure of the petals, allowing relative movements between the facade and the spatial network structure of coverage. This decision was taken to prevent that any movement of the cover, mainly due to oscillations for snow loads, wind or thermal expansion, can lead to the crisis of the glass.

The Tbilisi Public Service Hall includes: the National Bank of Georgia, the Minister of Energy, the Civil and National Registry.

The Tbilisi Public Service Hall is located in the central area of the city. The building covers 28,000 m² and is made up of seven cantilevered volumes designed as office space. Each of these sections consists of four floors located on different levels. The volumes are arranged around a "central public plaza" that is considered the core of the project and where the various front office facilities are located. The offices are also connected by internal footbridges that stretch between the various floors. The cantilevered office volumes and the central public atrium are covered by eleven huge "petals" that are formally and structurally separate from the rest of the building. The Tbilisi Public Service Hall houses the National Bank of Georgia, the Minister of Energy and the Civil and National Registry. The lighting design is based mainly on lines of light that are used in the general circulation areas, the offices where computers are common and the meeting rooms. IN60 luminaires have been installed in the corridors on all the floors and in the offices where they provide general lighting. In the corridors these luminaires emphasize the horizontal stretch and spread of space, whereas in the offices they guarantee visual comfort to those working with computer screens. In some corridors recessed Reflex Easy luminaires have been fitted to integrate the general lighting effect with distinctive zones of accent light, and in some executive offices, pendant Zyl luminaires have been installed for their decorative effect. iPlan standard lamps have also been added to allow customised light to be created on the front desks.
