These projects can
include over 100 peerto-peer fire detection
and alarm panels with
hundreds of auxiliary
power supplies monitoring
and controlling more than
10,000 devices. Those
devices, in turn, are

alternate suppression
systems, elevator
controllers, and more

control systems.
phase is always a major challenge. This
is when critical decisions are made that
will assist the project in meeting its
budget and schedule, and for achieving
optimum system performance during
its life cycle.
NFPA 3 defines the planning phase

and life safety commissioning team
is formed and initial project concepts
and owner's project requirements are
developed. Knowing early in the planning phase what your commissioning
challenges will be allows the fire commissioning agent to push planning
goals to meet system performance
objectives while understanding their
limitations, with the additional objective of ensuring a minimum level of
safety demanded by the adopted codes
and standards.
In most casino/resorts, a major
portion of the building is dedicated
to assembly occupancies that include
gaming, theaters, event arenas, convention spaces, conference centers,
ballrooms, restaurants, bars, and similar spaces. Planning needs to recognize
not only the size but the complexity of
the fire and life safety systems. Code
and standard requirements found in
mega-assembly areas are generally
more numerous and restrictive due
to the high occupant loads; even the
comparatively small Sands Macao
has a total gaming area of approximately 229,000 square feet, with a
legal occupancy load of over 20,000
in the gaming areas alone. The largest
project, the Sands Cotai Central, has a
GUTTER CREDIT
and standards to supplement or replace
local regulations. But the adoption of
any new standard can be a challenge
when a jurisdiction already has fire and
life safety regulations in place that have
worked relatively well for smaller, simpler buildings. Those same regulations
may not fully address the unique architectural designs or unfamiliar hazards
associated in larger, more complex facilities that have significant areas dedicated
to high-occupant-load assembly use.
Through our work in Macau we have
identified important ground rules for
each of the four project phases that
can help stakeholders avoid common
mistakes related to commissioning.
With the trend of building big being
embraced around the world, anyone
involved in the commissioning process
is urged to consider a handful of key
practices that can effectively shape
expectations and streamline the steps
necessary to getting a facility up and
running, on time and on budget.
