Separating underground metro lines under operation in BakuSYSTRA
The “28 May Station” is the only transfer station between the
existing Green and Red metro lines in Baku. As part of the huge
development strategy of the metro network, the complete
separation of the existing underground lines has been planned
at this location, in order to simplify the operation of the future
metro system.
The extreme challenge of the project is represented by the
need of achieve the separation of such lines over a breakdown
of the operation of just five weeks. The lack of direct access
from the surface, a complex geology with artesian water
layers, a congested underground space and sensible buildings
represent additional constraints.
The chosen design solution consists in creating a complex
steel pipe jacking frame around the operating tunnels and then
excavating under such frame two large caverns where the
separation of the existing lines and the construction of the
new metro tunnels will be achieved. Soil treatments have been
conceived to mitigate the geotechnical risks and to reduce
possible impacts on the existing structures.
The paper illustrate the challenges of this extraordinary project,
one of the most complex underground structures under study,
the design solutions and the risk management approach used
to manage the complexity and to design the mitigations
measures.

Need for platform-to-track intrusion detection systems in automated metro linesSYSTRA
The “communications-based train control” is defined by the IEEE 1474 standard as a continuous automatic train control system whose intelligence goes far beyond the basic train driving.
CBTC has become the heart of the metro system and, used for services with high added value, can improve availability and safety, which are the main concerns of the operators. To keep stations platforms a safe place while the grade of automation is growing, protection systems are needed.
Even if platform screen doors seem to be the ultimate solution, in some cases other detection systems can be more suitable mainly due to cost considerations or complexity of migration and infrastructures adaptation.

Architecture is the art of spaces. The human feelings were influenced by architectural
space from time to time. Relating to the design of a history museum, it could evoke a
certain feeling or memory of a historical event. This dissertation focuses on the
influence of architectural space over period of times.
A theoretical as well as practical key issue in the design of museum and galleries is how
the layout of space interacts with displays to create a specific effect, express the intended
message to visitors. This dissertation aims to capture and represent the history of
mankind’s understanding of space in the design of an architectural building.
