Centennial Tower, SingaporeEdit profile
Centennial Tower is a 158 m (518 ft), 37 storey high-rise skyscraper in the central business district of Singapore. It is located on 3 Temasek Avenue, in the zone of Marina Centre. The building is nearby other skyscrapers such as Millenia Tower, and Suntec City. It is less than 100 metres away from Promenade MRT Station.
The building won the Building and Construction Authority's Best Buildable Design Award in the Commercial & Office Buildings category in 1999.
The tower was built at a total cost of S$149 Million. It has a gross floor area of 66,270 square metres.History
Centennial Tower was designed by several architects, namely Kevin Roche John Dinkeloo & Associates, Johnson/Burgee Architects, DP Architects, and Philip Johnson/Alan Ritchie Architects. The building had a 23-month contract period, and was completed in 1997. Other firms involved in the project include Pontiac Marina, Dragages at Travaux Publics, Meinhardt, Sika Services AG, Building Systems, Moody's Investors Service, and McKinsey & Company.
Although completed in 1997, it was structurally designed and built to allow for future upward expansion by as much as 15 additional stories to reach 52 stories. During the construction of the building, the use of innovative and newer construction techniques allowed it to rise 20 stories in just 3 months, one of the fastest rates of construction then seen in Singapore. This enabled the contractor to save 5 months of construction, as compared to using the conventional method. Precast staircases, prefabricated reinforcement for the core walls, beams and columns were also used to enhance the productivity on site.Damage incident
On 10 February 2011 between 8:45pm and 9pm, 2 women were injured slightly by debris when a granite slab, estimated to be the size of half a mahjong table , which was part of the building facade, fell from the 25th floor. The building facade, designed and installed by French firm Dragages in 1997 had been checked in July last year and was certified safe by Dragages and its appointed building consultant Meinhardt.Architecture
The tower has an elliptical structure, which reflected the curvilinear frontage of Temasek Avenue. Similar to its neighbour Millenia Tower, the 360 degree windows and large floor plates provide better space efficiency. Most of the offices have good views of the city area of Singapore.
The contractor designed special formwork system, to suit the curved profile of the facade. The column, wall and facade were all constructed in the same operation by using the specially designed formwork. Telescopic table formwork system was used for the construction of the beams and floor slabs. The use of system formwork produced a high quality finish, which eliminated plastering. In fact, all the components were skim-coated.
To clad up the building, granite cladding and a curtain wall were used. The curtain wall, which has a total area of 7,773 m2 (83,670 sq ft), was standardised to six different panel sizes. Off-site fabrication of these wall system made installation faster. This reduced the number of site labour.
The tower is crowned by a twelve metre high ornamental trellis. This complements the adjacent pyramid atop Millenia Tower.Amenities
Centennial Tower is built on a two-story basement carpark, which is a continuation of the Millenia Walk carpark.
