INTRODUCTION
1.1
This document is intended to give the detailed requirements of a Mass
Rapid Transit (MRT) Station and is to be read in conjunction with the
Infrastructure Design Criteria Volume B Part1 MRT Station which gives the
general requirements to be considered in the design of the station.
1.2
The room areas and spaces are indicative and serve as a guide only. The
actual requirements will require further coordination with the designers,
consultants, system-wide contractors, service providers and equipment
manufacturers including requirements on equipment installation,
maintenance, operation, delivery / access routes and future asset
replacement

ROOM NAMING CONVENTION
2.1
General
2.1.1
Every space within the station shall have a descriptive identifier or ‘Room
Name’ so that during construction and eventual operation, the function of
the space is easily understood.
2.1.2
The full room name and an abbreviated room name for each room are
included on each room datasheet in subsequent sections.
2.2
Application of Names
2.2.1
All Civil and E&M plans may use either the full or abbreviated names but a
list of the acronyms, with their full names, must be included on the title page
for reference.
2.2.2
All operator interfaces or supporting documentation from Civil or E&M
Contractors must use either the full, abbreviated or combined names, but
reference must be made within the documentation to the full name for each
acronym.
2.3
Duplicate Rooms
2.3.1
For all spaces with identical names, the name shall include an identifier
after the room name. This identifier shall be a number unless otherwise
indicated in the room datasheet, e.g., ECPs and Intake Air Locks.
2.3.2
Any numbering included after the room name is dependent on the relative
bounds of the tracks as advised by the Authority.
2.4
Escalator / Moving Walk Control Panel Closets / Rooms, Escalator /
Moving Walk Pits, Lift Motor Rooms, Lift Shafts and Lift Pits
2.4.1
Escalator / Moving Walk Control Panel (ECP/MWCP) Closets / Rooms,
Escalator / Moving Walk Pits, Lift Motor Rooms, Lift Shaft and Lift Pits shall
be linked to the escalator / moving walk / lift by including the escalator /
moving walk / lift number in the ‘room’ name e.g. the ECP closet serving
Escalator B2E01 shall be named ‘ECP - B2E01 Closet’.
2.4.2
Note that this is the name of the room. The room number is separate and
would follow the standard numbering convention, which uses the level
where the room is located.

ROOM NUMBERING CONVENTION
3.1
General
3.1.1
Every space within the station shall have a unique identifier or ‘Room
Number’ so that the space can be scheduled and cross referenced with
items within the room for use during construction and for eventual operation
and maintenance.
3.1.2
The room number shall compose of a two-digit level number (01, B1, B2,
B3, etc.) followed by a three-digit number applied sequentially from left to
right across the general arrangement plan for the station. For example –
room numbers moving from left to right on the drawing at concourse level
(B1): B1001, B1002, B1003, etc.
3.2
Additional or Relocated Rooms
3.2.1
All additional or relocated rooms shall use an additional single letter suffix.
3.2.2
All additional or relocated rooms shall be renumbered to reflect their new
position.
3.2.3
For example – two additional or relocated rooms located between rooms
B1002 and B1003 would be numbered B1002A and B1002B.
3.3
Escalators, Moving Walks and Lifts
3.3.1
The escalator, moving walk or lift shall be numbered using the lowest level
of the escalator, moving walk or lift followed by the letters E (Escalator),
MW (Moving Walk) or L (Lift) followed by a two-digit number. E.g.,
escalators going up from the platform are numbered B2E01 and B2E02,
etc.
3.4
Staircases
3.4.1
The staircase shall be numbered using the lowest level of the staircase
followed by the letter S followed by a two-digit number. E.g., a staircase
going up from B1 is numbered B1S01. This applies to staircases in both the
public and non-public areas.
3.4.2
Spaces for enclosed staircases shall be numbered using the staircase
number and shall not be numbered using standard room numbers in 3.1
above. E.g., staircases going up from B1 would be B1S01, B1S02, etc.
Should B1S02 be enclosed in a stairwell, the resultant space would also be
numbered as B1S02.
3.4.3
Where doors occur along the route of a staircase this will cause a break in
the numbering, but not in the name. E.g., exit staircase 3 may be numbered
B2S03 at its lowest level but then passes through a CD ‘Blast Lock / Access
Lock’ at concourse level (B1). This ‘Blast Lock / Access Lock’ would have
Jan 2022
Page 8 of 160
Infrastructure Design & Engineering Group Key Document
Infrastructure Design Criteria – Volume B Part 1
E/GD/09/130/VOLB1/A1
IDC / VOLB1 / Annex B / Page 9
its own room number (e.g. B1076). Thereafter, up to the doors at grade, the
staircase would remain named ‘Exit Staircase 3’ but the number for the
space for the second leg of the staircase would be renumbered ‘B1S03’ to
signify the break caused by the Blast Lock. If there were no break in the
staircase, the staircase will be numbered B2S03 all the way to grade.
3.5
Closets
3.5.1
Closets, including those used to house services, shall be numbered from
left to right separately from the rooms and use the letter C (closets) to
distinguish the nature of the space. The numbers shall also have a prefix
denoting the lowest level of the space as with general rooms. Example –
closets, and doors from those closets, at level B2 would be identified by the
numbers B2C01, B2C02, etc.
3.6
Doors
3.6.1
Doors and access hatches for these spaces shall be identified using their
respective numbers followed by a suffix A, B, C, etc. for each door from that
space, e.g., 2 doors to room B1002 would be numbered B1002-A and
B1002-B. The doors are linked to particular spaces as follows:
If the door links a room to a common area (e.g. service corridor) or
public area, the door number will follow the room number, whether it
swings inwards or outwards.
If the door links a common area (e.g. service corridor) to the public
area, the door number will follow the common area number, whether
it swings inwards or outwards.
If the door opens between two rooms or common areas, it will follow
the room or common area from which it swings out from.
Doors to staircase, closet and duct will always follow the number of
the staircase, closet or duct.

STANDARD LOCKING HARDWARE SETS
4.1
General
4.1.1
Basic locking sets should apply to most door hardware arrangements
required within a station. Other locking sets can be derived by the designer
by addition of a suffix to the set code (e.g. EM1 for a modified
electromagnetic locking door). Consult with the Authority if additional
locking sets are required. Include reference to the components of each
locking set as an attachment to the door schedule which would include both
the standard sets below and any agreed additional sets.
4.1.2
The use of standard locking hardware sets are identified under the doors
section of each room datasheet.
4.1.3
Designers shall comply with all requirements of Code of Practise for Fire
Protection in Rapid Transit System (CPFPRTS).
