The prestigious 600-room Atrium Hotel is located on New Petchburi Road in the heart of the city of Bangkok. The project includes a commercial complex on the same site with common recreation facilities, restaurants, car parking and roof-top helipad. The building consists of 25 floors above ground in addition to 3 basements and a huge atrium topped by an arced glass roof. Due to the treacherous sub-surface conditions of water-logged soft clay, bored cast-in-situ piles of upto 1.5 m dia and 60 m length have been provided. Prestressed (post- tensioned) concrete slabs of only 230 mm average thickness span across column grids of 8.2 m * 9.7 m with cantilevers upto 4.9 m. Designing for the large nos. of perforations due to passage of ducts through the slab presented a significant challenge.
