The KL CAT ERL
Station is located within the KL Sentral Rail terminal which
also services the KTMB Intercity, KTMB Commuter and PUTRA
The main station space
for the ERL consists of two large separated spaces, namely
the Arrival and Departure Halls. Each concourse space is 97m
long, 47m wide and up to 17m high. At 7.3m above the Concourse
Level, the PUTRA LRT viaduct runs across the Concourse space.
Computer fluid dynamics
(CFD) modeling was done to study the stratification effects
on cooling load, appropriate air distribution strategy and
the effect of movement of the PUTRA LRT train through the
The CFD modeling utilizing
ESP and Microflo softwares was done in house over a period
of two months.
Smoke spill design for
the Concourse and Platform areas were based on fire size analysis.
For the platform area, due to the complexity of the various
fire scenarios, a Cause and Effect Matrix Chart was devised
to document the design requirements. The Chart was referred
to extensively during programming of the fire systems for
testing and commissioning.
Instead of the usual
two speed fans or reversible fans for smoke spill at the Platform
during fire mode, by matching fan curves, appropriate fans
were selected such that the flow rates during fire mode could
be achieved by just switching on the standby fans in addition
to the duty fans during fire mode. This resulted in substantial
Special attention had
to be paid to routing and location of services in view of
the large volume spaces and constraints of working entirely
within the core and shell spaces allocated.
All services had to
be interfaced with the KL Sentral infrastructure and provisions.
