The Marina Bay

Sands SkyPark is a

triumph of modern

engineering,

featured by the likes

ofNational

Geographic and the

Discovery Channels

Build it Bigger for

its bold look and

daring design

elements.


4/39

The SkyPark spans

the top level of all

three Marina Bay

Sands hotel towers

626 feet (191

meters) above the

ground.

The SkyPark has a 213-foot (65-meter) cantilever edge

In 2006, the Las Vegas Sands Corporation and visionary architect Moshe Safdie were

awarded the bid to build Singapores first integrated resort. Natare Corporation was

hired to design, build and install the SkyPark pools.


8/39

They include a 146-meter (478-foot) infinity-edge stainless steel pool, three large

hydrotherapy spas, a wading pool and a reflecting pool -- all on the 55th floor of the

resort.


9/39

Comprising 422,000 pounds (191,416 kg) of stainless steel and holding 376,500 gallons (1.4

million liters) of water, the SkyPark pool is the worlds largest infinity pool at that height.


10/39

The pool is also composed of 254,000 ceramic tiles.


11/39

The mechanical systems were designed with multiple and independent recirculation and

filtration loops allowing for a variety of operational modes depending on the load (swimmers

in the pool), weather conditions, feature effects and hours of operation. The filtration system

has a flow rate of 5707 gallons per minute (1794 square meters per hour).


12/39

The entire system was individuallyengineered

and structurally designed using the

most comprehensive computer

design and modeling tools. Three-

dimensional models were created

long before manufacturing or

construction began.


13/39

A scale model of the pool enclosures and submersed connectors was built and tested at

Natares headquarters in Indianapolis.


14/39

October 2009

This mock-up allowed Natare to troubleshoot and modify the sealing method in order toprovide a superior product never before used in elevated pools.


15/39

The pool interior is finished

with ceramic tile adhered

directly to the stainless steel

foundation.


16/39

The SkyPark pools consist of three separate shells; the middle shell constructed atop the middle

tower, and the outer shells constructed on bridges that connect the middle tower with the outerones.


17/39

The structural

bridges between

each hotel tower

were installed with

a 3-inch pitch, orcamber, to

accommodate the

weight of the pool

when filled with

water.


18/39

Because the pool was built atop three high rise towers, engineers had to consider the fact

that wind, and the force of gravity would cause the towers to sway and move independently

of one another.


19/39

They accomplished this feat by constructing four movement joints beneath the main

pool; each with a unique range of motion.


20/39

The three pool shells are joined by connectors at each of the movement joints thatdouble as shallow-water terraces for pool loungers.

Movable Terraces


22/39

In addition to wind, the towers are also subject to settlement over time, which couldcause any of the three pool shells to slope.


23/39

Natare engineers designed and built

custom jack legs at more than 500

points beneath the pool to allow forfuture adjustment.


24/39

The jacking system ensures the infinity edge will remain within its original placement andcontinue to function properly.


25/39

Another obstacle Natare faced involved space limitations.


26/39

Ideally raw materials would be shipped and fabricated on-site, but in this case crew

members shared a very restricted workspace with many other contractors on a constructionsite in the sky


27/39

Natare developed a plan to pre-fabricate all components from their manufacturing

facility in Indianapolis and ship them to the site in more than 30 ocean freight

containers.

In all, 40,000 pieces were used to construct the pool enclosures; these pieces werecondensed to less than 2000 to be assembled on site.


33/39

Many of the pools sub-assemblies were hoisted to the top of the towers via crane.

Technical Details

The pools are composed of 422,000 pounds of stainless

steel and finished with 254,000 ceramic tiles adhered

directly to the stainless steel shell.

The pools hold 376,500 gallons (1424 cubic meters) of

water.

The weight of the pool when filled with water is 3.6Million pounds (1843 tons; 1672 metric tons).

The entire SkyPark is 340 meters (1115 feet) long and 40

meters (131 feet) wide.

The pools mechanical system, also designed, built and

installed by Natare, filters the pool water at a rate of

5707 gallons per minute.

The pool components traveled from Indianapolis to

Singapore, a total distance of 9,523 miles (15,325 km), as

the crow flies.
