The building will feature a highly efficient building geometry supported by diagrid
superstructure that achieves 20% weight reduction when compared to traditional rectangular structures, and the building envelope has been designed so that certain components play multiple roles, such as shading elements with incorporated renewables positioned at optimised angles to receive maximum exposure to solar radiation, while providing maximum shading to the vision areas without obstructing external views.
It features a distinct, thermal efficient diagrid
that provides a vast open interior.
The triangulated diagrid
facade was inspired by the skin of a pine cone.
Architect Moshe Safdie has designed the project, based on a diagrid
design to promote efficient use of structural steel, greater structural stability and a column-free interior to optimise internal surface area.
form was selected partly for architectural expression and aesthetics.
The facade is a self-supporting, highly engineered, diagrid
This structure is echoed by the dramatic internal diagrid
of the atrium which transfers its load to the concrete core on the 19th floor.
Doha Tower is the first tall building to use reinforced concrete diagrid
This might have been covered by a utilitarian roof; instead, something in the best Victorian railway tradition has been created: a soaring diagrid
shell structure of complex geometry designed by Arup which is high enough to enclose a long and pleasingly sinuous first-floor balcony to contain more of the retail facilities a modern station needs.
Koolhaas has long had an interest in the interplay of field and shape, in the sense described by Fried, and the Seattle Library demonstrates a complex, purposefully unresolved relationship between its diamond-patterned diagrid
skin and its multifaceted building volume.
For the time being, however, this striking 103-storey building, characterised by its rounded triangular plan, giant order diagrid
structure (spanning up to 12 floors), with offices on levels 1 to 63, a Four Seasons luxury hotel between 64 to 99 (due to open later this year), and an observation deck on levels 100 and 101, will stand as the city's tallest building at 440m.
Three-dimensional coordinates for each diagrid
component are calculated using Tekla software that ensures seamless integration and assembly of the frame and supporting beams.
