The pool and spas at the Ritz-Carlton Hotel & Residences and JW Marriott at the LA Live are designed to complement the overall entertainment experience at the LA Live entertainment complex in downtown Los Angeles. These pools serve as not only recreational
amenities for the Hotels, but also as social focal points, as they
become the newest gathering spots in and evolving Downtown LA
culture. Their modern aesthetics embody the spirit LA Live, and the
refined lifestyle represented in the overall project.
The pool area for the JW Marriott offers views into Nokia Plaza,
the Hotel Lobby, and neighboring Staples Center and Nokia Theatre.
The pool area for the Ritz-Carlton showcases the surrounding
downtown Los Angeles skyline.
Several specific design features further integrate the aquatic
amenities into the overall tapestry of the LA Live complex. Paving
patterns from Nokia Plaza and the Hotel were carried into the pool
decks, and incorporate the shape of the minimalistic, rectilinear
pools. In addition, the “zero-edge” design of the pool
copings ties directly into the raised pool deck paving system,
merging the design of the pools and spas with their
When it comes to the pool system engineering, both pools and spas
represent the state-of-the-art in above-grade swimming pool design,
engineering and construction. These salt-water system based vessels
required the utmost care in structural engineering and interface
with the Architect, General Contractor, and sub-trades. In
addition, proper pump selection and plumbing sizing dramatically
reduces energy consumption, making the systems more affordable to
run and significantly reducing environmental impact. Also,
maintaining proper circulation system flow in conjunction with
proper pump selection velocities, which works to lower the
acoustical threshold, helps to meet the noise thresholds expected
from a 5-star resort.
The primary challenge was pool construction on top of a high-rise
tower, and over a three-story Hotel lobby atrium. Other challenges
related to facilitating construction include delivery of materials
via crane, creation of a permanent delivery system for pumping
concrete up to the tower, the use of foam panels used to reduce the
weight of the reinforced concrete shell structure, and coordination
with waterproofing and the raised deck system.
As part of this exciting, newest addition to the downtown Los
Angeles skyline, these pools take on tremendous cultural
significance and may someday be considered historic installations.
Until then, they stand as prime examples of design and technical
excellence, the very best the aquatic industry has to offer.
