In Doha, just like Sydney, the existing airport was too small and surrounded by built-up areas. In contrast to Sydney, the Qatari Government decided to do something about it, and built a new airport on reclaimed tidal flats at the edge of town.
The New Doha International Airport was a huge project. While Osborn Consulting Engineers role, as the designer of the roof over the multi-storey carpark, was relatively small, the design of these structures was a major project for the Brisbane office. Leaving aside hail protection structures, the 29,000 square metre roof area is larger than any other fabric structure designed by Osborn Consulting Engineers. The structural form is the classic hypar, of Ferrari 1302 around the edges and Ferrari 1202 internally, and aluminium louvres over the walkways. Each carpark has 69 hypars, and the carparks are mirror images of each other. Osborn Consulting Engineers clients were Sail Canopy and Alfasi, both based in Singapore.
