During the construction phase of the hotel, the crew set a record by building a new floor every
four days, which is the fastest ever for such a large project in Singapore. • One of the main SkyPark
attractions is the massive 150-meter swimming pool, which is the largest elevated outdoor swimming pool in the world. Swimmers enjoy a spectacular view of the city as they swim along the 150-meter long infinity edge. Combined, the 3 swimming pools contain 1.424 million liters of water and contain 254,000 tiles.

SKYPARK INGENUITY
Te most complex and challenging aspect of building the Marina Bay Sands Hotel was that of the SkyPark. Architects were faced with numerous challenges when they set out to design and build this magnificent structure. Perhaps their toughest obstacle was determining how to hoist the massive 7000-ton structure from
the ground to its new elevation of 200 meters above the city. To accomplish this impressive task, the team employed a computer-controlled lifting device, which consisted of a series of strand jacks, which were mounted on giant temporary lifting gantries. Te precision lifting system hoisted the heavy steel structure into place. Strand jacks have been used in the past to hoist bridge structures into place, erect oilrigs, and con-
struct power stations. However, the SkyPark project was the first strand jack lift of this magnitude. Te strand jack system incorporates a series of cables and hydraulic cylinders to raise the structure incrementally. Te process is completed by expanding the hydraulic cylinders, clamping the load, releasing the trailing end, contracting the cylinders, and then clamping the trailing end prior to start- ing the process over again. To ensure there were no issues with the lift, the entire structure was pre-assembled offsite to
confirm the fit of the 14 individual mating components. Te large bridge assembly and cantilever portion of the SkyPark were pre-assembled at the base of the Marina Bay Sands towers to eliminate as much “sky-high” assembly as possible. Each lift would take as long as 24 hours to complete from start to finish. Te entire lifting process would take 3 months considering the time to hoist the entire structure, the hull cladding, an enormous swimming pool, the trees, and other building accessories. Te second hurdle with a project of this magnitude was dealing with the influence of the wind. When handling a large structure at these high elevations, the affect of the wind would be substantially magnified. To control the giant structure as it was hoisted, the construction team utilized a system of cables to reduce the swinging during the lifting process. Te team would monitor the wind condi- tions and speed prior to the initiation of each lift. Architects for the SkyPark development focused on the effect of the wind when designing the
project. In consideration of guest comfort, the engineering team conducted a series of wind tunnel tests to ascertain the effect of wind pressure on the overall structure. Te data collected from the tests led to a façade, which was designed in such a way that it would reduce the impact of the wind.

Te SkyPark Hull cladding consists of composite aluminum paneling on Aluminum extrusions/runners. Tere are approximately 2 million pieces of various fix- ings, i.e., s/s rivets, screws, bolts and nuts in the SkyPark Hull cladding system, which has an area of 14,500 m2, and this equates to 9456 panels. Te length of aluminum extrusions used is 62,500 meters (62km), and the esti- mated weight of the Hull cladding system is 350 tons.
UP IN THE AIR Te numbers involved in what it took to build
the Marina Bay Sands Hotel and Sands SkyPark are an accountants dream, coming in at a cool $5.7 bil- lion. Te massive, eye-stunning hotel is over 9 mil- lion square feet. So just what does that amount of space include? Te question, in the case of this hotel, is what doesn’t it include! Te Marina Bay Sands Hotel is made up of three
sloping towers that have straight legs. Te legs each con- nect at level 23 so that they form into a single building. Tere was a lot of thought that went into every details of how this building was going to be constructed, with the Tower 1 slope as steep as 26 degrees. Because of the complexities that went into the design of this hotel, it is considered to be one of the most complex hotels that have been built to date. Each day after the hotel officially opened in June 2010, the visitor estimates were at about 25,000 per day. And not everyone that visits is pulling up a bed in one of the hotels 2,561 rooms. Many people who live right in Singapore are reported to visit regularly, paying a monthly fee for use of the SkyPark. Within the hotel, visitors will find everything they need for a great time, regardless of what that may include.
