The Chalupnik House is a sophisticated home for
six constructed on a challenging site in Prague. It
has an open western elevation, a rather closed
eastern elevation (with the minimum amount of
openings), and an almost closed northern elevation. There is no southern elevation, as the volume
of the house slides into the slope. Consequently,
the roof is devised as a green roof, with grass
planted on it.
The centerpiece of the project was the comprehensive Bentley 3D model, which ensured continuity, total coordination and integration, and targeted communications. It also helped in developing
specific components for the house by shifting the
design of the component to the architect, leaving
the manufacturer in the role of manufacturer only.

Over the last decade, the Dublin Docklands have
undergone major redevelopment to lift the area
from derelict industrial and warehouse-type sites
to modern urban quarters. Situated at the most
suitable inner-city location in Dublin to allow for a
cluster of high-rise buildings, the design includes a
48-story mixed-use tower above a podium deck
and two basement levels. The first 10 levels are
for office use, followed by 32 levels of residential.
The tower is vertically split into zones of different
use separated by public and semi-public gardens.
These zones are unified by a second outer glass
facade that wraps around the building in facetted
planes, giving the tower a crystal-like appearance. This double-skinned construction was also
chosen to allow for maximum natural ventilation.
The design process was guided by an intensive
assessment based on 3D models of a broad
urban scale. The design team undertook analysis
of the urban situation and visual impact. This
included animated visualizations simulating the
tower in its context.
Many projects will be phased over several years,
but the stability of file format and backward compatibility in MicroStation have removed the
requirement of updating information. All data
from different program versions is readily available to all users. ;
