In 2006 ONL has won the design for the Al Nasser Headquarters tower in Abu Dhabi in the United Arab Emirates via an invited international competition. The client Mr Al Nasser owns a steel company and has chosen ONLĀ“s iconic design, by far the most challenging of the competition entries, as he liked the exposed nonstandard steel structure inside and the metal duotone finishing of the exterior facade panels. Only in the final design stage the client as represented by Northcroft Middle East realized that all steel components and all windows are indeed different in shape and dimensions. They were fascinated by this fact but at the same time worried if this would be feasible within the strictly commercial budget they had defined for this project. Thanks to the precise control ONL successfully has monitored on the data as extracted from the Revit BIM model they were convinced that it was feasible indeed. The smart BIM model has served many purposes. In the first place ONL appointed no more then one single highly skilled architect, the young Gijs Joosen MSc, to be the executive architect and the BIM modeller in one. No information was lost in translation. The BIM model allowed for tweaking the curvatures of the shape of the office tower until the requested maximum GFA was reached, while maintaining the uniqueness of all constituting components and the unique configurations of each office floor. Any change in the curvature affects the square footage of each floor and hence the allowed GFA. Furthermore it facilitated to communicate with high precision with the local architects ACG who were responsible for acquiring the building permit and responsible for the calculations of the steel structure. The Al Nasser HQ is now under construction and will be finished in 2013.

PS: the building is now renamed into the LIWA tower
