Doha’s new desert rose – geometric complexity par excellence
In the course of Doha’s development into a global financial, cultural and tourism center, a new national museum was built in the capital of Qatar. Due to its size and geometric complexity, the building designed by Jean Nouvel required the highest standards of planning and installation of the building envelope. The basic idea of the design was the complex, rosette-like structures of so-called sand roses – structures that form naturally in the desert during the evaporative crystallization of gypsum.
Rosette-Like Structure of Sand Roses as Basic Motif
This motif was used to develop a building complex that measures approximately 400 m × 250 m in footprint and reaches up to 40 m in height. The building is composed of 600 different, discus-shaped elements that are intersected with each other. Based on a master detailed design and tender by Jean Nouvel, the overall project was awarded to the Korean general contractor Hyundai at the end of 2011.
World’s Largest BIM Model of Its Time
The central component of the planning process was a BIM model (Building Information Modeling). All the specialist planners and contractors involved were able to continuously feed their planning results into this model. In this way, it was possible to get a grip on the high geometric complexity of the project and prevent collisions of individual components. The BIM model was managed in the Gehry Technologies software system. Due to the enormous size of the project and with its extremely high level of detail (LOD 400), it was at the time the largest model of its kind in the world.
BIM Award 2016 for Werner Sobek
A particular challenge in the Qatar National Museum project was the planning process during construction. The ongoing overall coordination required permanent adjustments to the 3D BIM model in all trades. This required highly efficient planning change management, which included state-of-the-art approaches and processing tools with automatic collision detection and the simplest possible parameterized tracking of planning data.
Werner Sobek was honored with the 2016 BIM Award for its innovative use of BIM technology.
