Singapore faces a problem of how to deal with its waste and has consequently designated a site in the industrial area of Tuas for an incinerator and waste treatment plant. To access the site, two bridges are required to cross a waterway serving cooling water to an existing power station. This paper discusses the constraints faced in the design and construction of the bridges and how the Designer and Contractor developed innovative solutions to overcome challenges they posed. In planning the bridges, it was essential that at no stage construction activity impacted the operation of the inlets and the associated access provisions. To meet this requirement, the bridges needed to span a clear distance of 75 m. With the aim of minimising the programme time required to construct the bridge, precast techniques were to be used extensively, with the pier heads each side of the main span being precast shells 28 m in length and the main beams being 50 m long precast U beams. |
