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.

The SkyPark spans
the top level of all
three Marina Bay
Sands hotel towers
626 feet (191
meters) above the
ground.

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.

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.

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.

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

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).

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.

A scale model of the pool enclosures and submersed connectors was built and tested at
Natares headquarters in Indianapolis.

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

The pool interior is finished
with ceramic tile adhered
directly to the stainless steel
foundation.

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.

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.

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.

They accomplished this feat by constructing four movement joints beneath the main
pool; each with a unique range of motion.

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

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

Natare engineers designed and built
custom jack legs at more than 500
points beneath the pool to allow forfuture adjustment.

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

Another obstacle Natare faced involved space limitations.

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

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.

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.
