Marina Bay Sands is an integrated resort fronting Marina Bay in Singapore. Developed by Las Vegas Sands (LVS), it is the world's most expensive building, at US$ 4.7billion, including the cost of the prime land.

Marina Bay Sands is situated on 15.5 hectares of land with the gross floor area of 581,000 square metres. The iconic design has transformed Singapore's skyline and tourism landscape since it opened on 27 April 2010. The property has a hotel, convention and exhibition facilities, theatres, entertainment venues, retailers and restaurants.

How it get started

Marina Bay Sands was one of two winning proposals for Singapore's first integrated resorts, the other being the Resorts World Sentosa, which incorporates Universal Studios Theme Park. The two resorts aimed to meet Singapore's economic and tourism objectives, and have 30-year casino licenses, exclusively for the first ten years.

On 27 May 2006, Las Vegas Sands was declared as the winner to develop the Marina Bay site in the prime new business district of Marina South. LVS highlighted its forte in Meetings, Incentives, Conferencing, Exhibitions (MICE). LVS's founder Sheldon Adelson is a pioneer in Las Vegas and the key to his early business success. In the Design Evaluation portion of the tender, a panel of local and international architects commended Sands' design as superior to other bids in terms of pedestrian circulation and layout, and it also fit in with the Marina Bay landscape best. They liked that the hotel towers were set back from the waterfront to open up expansive views of the city and the entire Marina Bay, making the skyline for Singapore's downtown more attractive and distinctive. Construction of the property commenced in early 2007 and was expected to be completed by 2009.

LVS submitted its winning bid on its own. Its original partner City Developments Limited (CDL), with a proposed 15% equity stake, pulled out of the partnership in the second phase of the tender process. CDL's CEO, Kwek Leng Beng said his company's pullout was a combination of factors – such as difficulties in getting numerous companies he owns to comply in time, as well as reluctance of some parties to disclose certain private information in probity checks required by the Singapore government. However, Kwek was retained as an advisor for Sands' bid.

The Design

Moshe Safdie was approached to lead the design on this massive project, ultimately taking inspiration from the form of card decks for the unique appearance of the three hotel towers. Other key structures of the property include the 200,000-square-foot (19,000 m2) ArtScience Museum, The Shoppes, Expo and Convention center and the casino. During the resort's planning and construction phases, feng shui consultants, the late Master Chong Swan Lek and Master Louisa Ong-Lee were consulted in regards to divination.

The engineering for the project was headed by Arup and Parsons Brinkerhoff. Arup had originally worked on prestigious projects such as the Beijing National Aquatics Centre and the Sydney Opera House. In spite of their experience in constructing challenging designs, the Marina Bay Sands project was described as the 'most difficult to carry out in the whole world' due to the amount of integration of the varied and advanced technologies needed to complete the project. Ssangyong E&C won the contract at 6.86 million dollar and completed the Marina Bay Sands Hotel, sloping up to 52 degrees from the ground surface in June, 2010.

The most dramatic landmark

The Marina Bay Sands hotel has three 55-story towers with 2,561 luxury rooms and suites, and is capped by the Sands SkyPark, which offers 360-degree views of Singapore's skyline. The SkyPark is home to restaurants, gardens, a 150-metre vanishing edge pool, manufactured by Natare Corporation in Indianapolis, Indiana, and the world's largest public cantilever housing an observation deck. This architectural marvel stands at a height of 200 metres and boasts 12,400 square metres of space. Dining options at the Skypark include restaurant Sky on 57, restaurant and nightclub KU DÉ TA, and executive club lounge The Club at Marina Bay Sands.

To help the Skypark withstand the natural motion of the towers caused by wind, engineers designed and constructed four movement joints beneath the main pools, each possessing a unique range of motion. The total range of motion is 500 millimetres (19.68 inches). In addition to wind, the hotel towers are also subject to settlement in the earth over time, hence custom jack legs were built and installed to allow for future adjustment at more than 500 points beneath the pool system. This jacking system is important primarily to ensure the infinity edge of the pool continues to function properly.

The Sands Expo and Convention Centre has more than 120,000 square metres or 1.3 million square feet of meeting space, making it one of the largest and most flexible locations in Asia. It is also the biggest MICE facility in Singapore, and the ballroom is the largest in Southeast Asia, capable of hosting up to 11,000 delegates. The Sands Expo and Convention Centre has five floors of exhibition and convention space, with up to 2,000 exhibition booths and 250 meeting rooms. It has hosted events ranging from banquets, theater-style conventions, to exhibitions and roadshows.

Marina Bay Sands is also home to the ArtScience Museum, With a form reminiscent of the lotus, the ArtScience Museum has been called "The Welcoming Hand of Singapore". It features an adjustable roof waterfall which uses rainwater collected when the roof is sealed in the day. The resort also features an Art Path designed by Moshe Safdie, incorporating 11 installations by five artists including Zheng Chongbin, Antony Gormley, and Sol LeWitt. The 11 art installations were commissioned to integrate seamlessly with Moshe Safdie's iconic architecture. These art installations form the largest art commissions ever completed as part of an integrated architectural process.
