SLS Hotel & Casino - Settled Slab Recovery Case Studies
When you’re in the casino business, every hour you are closed means
lost revenue. If repairs are needed, time is of the essence, and every
second you can gain by getting a job done right in minimum time possible
is critically important. When the SLS Hotel and Casino, formerly the Sahara
Casino, in Las Vegas, Nevada, noticed foundation damage in a bar area
of the facility, they called Ram Jack Las Vegas to take care of it as
quickly as possible.
A plumbing leak beneath the slab in the bar area of the SLS Hotel and Casino
had caused severe damage, resulting in as much as 3 in. of slab settlement.
While the leak was fixed prior to Ram Jack’s arrival, it had saturated
the area with water for a significant period of time, damaging over 500
ft^2. of slab in the area around the bar. Because the damage occurred
to a reinforced structural slab with channels containing electrical conduits
for the various gaming devices on the floor, the job proved to be complicated,
and it was necessary to consider the electrical requirements of the casino
games in the surrounding area.
Ram Jack Las Vegas worked with the casino’s engineering team to provide
a plan of action. After mapping out the channels in the slab to prevent
damaging electrical conduits, Ram Jack Las Vegas proposed installing a
grid of helical piles every 5 ft. in the affected area.
Because the work took place in an active area of the casino, Ram Jack Las
Vegas professionals worked between 12 a.m. and 8 a.m. nightly until the
job was complete. At the end of each “work day,” the job area
was cleaned, all holes were covered, and the carpet was replaced so the
casino could function without interruption. Ram Jack Las Vegas cored through
the 6-7 in. slab at each of the 15 pile locations and installed each pile
with a rotary torque head and extended resistance bar. Each pile was extended
to the underlying Caliche hardpan about 10-14 ft. below grade. Once the
piles were set, the support brackets were put into place and a jacking
bracket brought the slab up to the original floor elevation. A Ram Jack
retaining system was used to tighten and hold the slab in place. After
the jacking system was removed from all holes, a line pump injected sand
slurry under the slab to fill any voids, and all of the cored holes were
filled. The engineers and maintenance workers at the SLS Hotel and Casino
were more than impressed with the quality work performed by Ram Jack Las
Vegas as well as the fact that the job was done with minimal interruption
to casino business.
