One Raffles Quay (ORQ) is the first major development in the New Downtown District on the Marina waterfront. The developer, a joint venture between Hong Kong based Cheong Kong Holdings & HongKong Land and local developer Keppel Land, are constructing a landmark building called One Raffles Quay which consists of two towers, the North Tower, 50 storeys and the South Tower, 28 storeys. The site is being built on a geologically challanging area with at one end of the site a 40m layer of very soft Marine Clay overlaying hard S3 Bouldery Clay and the other only 15m of soft material before reaching the very hard bouldery clay. The foundations and basement is is further complicated by having a underground railway running right across it, indeed the North Tower foundations stradle the tunnels.

With an ambitious programme for the completion of the sub-structure works, Bachy Soletanche set to the task in September 2002 and are due to complete by the end of February 2003. Due to the nature of the ground, hard S3 bouldery clay, BSS called in several of our specialist operators from Hong Kong who are very experienced to heavy chiselling in similar ground conditions.
