Call Aldar. Share your Feedback. Aldar HQ. The complexities of simplicity indeed proved to be many, and the design of the HQ could only be a holistic one, merging architecture and structure. It became an object of both fields, showcasing the expansion and blurring of their respective limits in order to form a combined product.
The curved glass skin became one of its most complex components to be executed in record time. A concrete structure would have required unwanted internal supports and entailed time-consuming and costly on-site construction work. Therefore, the team developed a complex external diamond-shaped steel structure, called a diagrid, which achieved the striking shape of the building. The first of its kind in the UAE, the diagrid allowed the creation of structural efficiency and stability appropriate to the circular building.
This diagrid system eliminates the need for internal columns to support the building which would compromise the aesthetic appeal as well as the views from within. This improved the building's efficiency, providing layout flexibility for tenants. All panels on one floor are then exactly the same size with the same angle change at each joint due to the equal chord lengths along the circular line in plan. The rate of change of size of panels increases as one moves further away from the equator of the building with the top and bottom of the building being an exact mirror image of the other.
To further increase the repeatability of panels the joint sizes were sized so that the same panel could be utilized over a number of theoretically geometrically different floors without being able to visibly see the change in joint width.
This exercise allowed the initial architectural vision to be created with approximately ten panel sizes instead of the original 10, sizes that would have been theoretically needed before the geometry refinement. This three faceted building relies on its zipper-like element, a continuous glass and structural band that stitches the two main facets together, creating a slim continuous surface that is both vertical and horizontal, side and face, window and roof.
THE PROCESS With a fast track construction schedule of 30 months that was meant to meet the opening of the Abu Dhabi Formula One Grand Prix, architects, engineers and the many experts on board worked with a collaborative effort and helped smartly run the intricate overlap of design and construction with its new challenges and complexities.
This contractual joint venture arrangement was key to the successful design and construction of the project. A factor of zone 2A was adopted in the design of the HQ building based on advice from the municipality. To gather accurate data with regards the wind impact on the building, wind engineers built a scale replica of the entire city.
This gave them insight into how winds moved across the landscape, and more importantly, how the winds would impact the structure of the project. The design has been refined using the results of the wind tunnel tests and the wind loading for final design is based wholly on the wind tunnel results.
The development process: An innovative method of Analysis and Drafting was adopted during the construction of the Aldar HQ building. Engineering and model data were used at the earliest stages of the project to take full advantage of early procurement and optimized use of material. The structural analysis of the podium and tower superstructure was undertaken using the 3D finite element analysis program, Strand 7.
Foundation works began just 1 month after the design was sketched, before a full set of plans was developed by the engineers. The concrete cores were completed within a year. Within 14 months of the project start, the steelwork was already erected up to the fourth floor. Concrete elements, such as stairs, columns and even the bathrooms, were pre-cast. United Arab Emirates. Work Places. Description When challenged to create an iconic structure on Al Raha beach, MZ Architects decided to create a simple building that would possess the calm, ideal beauty of classical architecture while also having considerable expressive power, a building that would compete with the iconic architecture of the UAE and create a sense of place and identity for the area.
