Abstract
The project for the new Public Service Hall is part of an extensive construction
program to create more than 15 new buildings dedicated to providing Government
services and in particular the distribution and support of the digital ID service card.
Following aMDL’s previous experience to design the first Public Service Hall in
Batumi we were commissioned in September 2011 to design to Marnueli project.

Project Description
[The project for the New Public Service Hall is part of an extensive construction
program to create more than 15 new buildings dedicated to providing Government
services and in particular the distribution and support of the digital ID service card.

Following aMDL’s pervious experience to design the first Public Service Hall in
Batumi we were commissioned in September 2011 to design the Marnueli project.
The town of Marnueli is located about 30 kms to the south of Tbilisi and acts as an
important point of connection for roads leading to the neighbouring America and
Turkey. The site is located at a busy traffic intersection, which is transformed by
other construction projects including a new police station, local cultural center and
supermarket. With the new public service hall, that also integrates a TBC Bank, it is
intended to upgrade the surrounding public areas with a new town square, sculpture,
parking and pedestrian paving.
The building and its main entrance has been conceived to have a representative
relationship with the square and its surroundings and is flanked by wide pavements
and a public park to the rear.
We have purposely chosen to organize the building within a simple square plan form
with a central atrium as a point of focus of the internal layout and vertical
circulation. The presence of the building is further accentuated by ‘ floating ‘ the
public ground floor level five steps above the pavement, which also provides
daylight and natural ventilation to the parking under-croft below.
The building’s appearance and continuous façade system has been specifically
designed to represent not only the accessibility and transparency of the Governments
activities and its relationship with local citizens but also using 2 key elements give a
contemporary sense of technological lightness. The whole 2 level building is
enclosed by a full height structural glazing system based on 1.4m wide modules,
which in turn is wrapped by a suspended silver fibre glass mesh screen which
undulates by a suspended silver fibre glass to provide protective sun shading. At
night the membrane reinforced the idea of protected transparency emphasized by the
effect of internal and external lighting.
In contrast to the technological expression of the façade the main building structure
of concrete columns and coffered floor slabs has been left exposed to provide a
modular framework for the insertion of building services and the specific interior
furniture systems developed for the Public Service Hall and TBC Bank. On the
ground floor the 4.5m high space has been kept as open as possible so as to
maximize the visibility of the different services, the horizontal views and the
penetration of natural light. The main atrium staircase that connects the basement
and first floor levels is clad in natural oak wood and overlooks the central consulting
area.
The first floor provides offices for the Chief Prosecutor and his department as well
as back offices, meeting rooms and staff facilities. The spaces are accessed by a ring
corridor around the atrium and are organised to give perimeter workspaces the
maximum contact with natural light and views to the surroundings. Internal finishes
are kept to neutral palette so as to accentuate the colours of the standard
communication and interior service design system.
The building construction commenced at the end of 2011 and has been opened on
the 5th September 2012.

Facade Design
The concept and the design of the membrane facade is part our ongoing research to
develop new types of expressive solutions that combine specific formal languages
with the need to find practical and environmentally supportive construction systems.
Following our previous experience with the first Public Service Hall in Batumi we
chose to create a simple building plan with a central atrium as most appropriate for
the distribution of Public Service Hall activities but also create a very luminous and
open internal space. Externally the facade reflects the contemporary spirit of the
government2s services and by using a lightweight enclosure there is a strong sense
of accessibility and lightness. The buildings exposed concrete structures was
designed to create a ground level podium that ‘ floats ‘ above the parking under croft
3
and by raising the membrane facade just above the external paving and extending it
above the roofline the undulating form is an effective external views for all those
working and visiting the building.
Using models and 3d drawings we defined the overall proportions of the facade so
as to have the best balance of refined structural support and membrane dimensions.
It is composed of steel brackets fixed to the buildings floor slab at 5.6m centers,
which also support the external maintenance walkways, to which the membrane
structure support struts are fixed using purpose made connectors. A silver colour
PTFE coated mesh was chosen for its reflective, structural and lifespan
characteristics and whose transparency would provide the best sense of enclosure
and views. Following full scale prototyping by Tensaform at their manufacturing
base near İstanbul, the design and project management team were able to control and
refine the overall design.
