Room Number Guidelines
Preface:
The University currently operates a space inventory system which has two main components. The first is a
graphical building plan system which includes computerized architectural floor plans using AutoCad. In addition,
layering names and standards have been developed at McGill and are used for our reference floor plans. We ask
that consultants and / or architects, who produce plans, utilize these layering standards once they complete final
working drawings. The layering names and standards appear can be downloaded from: McGill University AutoCad
Layer Guidelines
The second component of the space inventory system is a room database using Oracle. This database includes
information concerning room numbers, room areas, room usage, departmental allocation and other information
that we require. This database is submitted, on an annual basis, to the MELS (Ministère de l'Éducation, du
Loisir et du Sport). This data is used by the MELS to calculate each university's annual capital grant and to
prioritize funding for new construction and major renovations. The data is also used to establish space norm
standards.
Room number rules:
1) All room numbers to have a maximum of 10 alphanumeric characters.
2) All room number tags, on the AutoCad drawings, to be on layer Upo-rm-num. The room tags are also to be
defined as an AutoCad block with data attributes. The block name is GEN-NUM-ROOM-25AT. Please contact
Stanley Glavac [email protected] in order to receive the room number block.
3) For all new building construction follow the room number sequencing as described in Table 1 below.
4) The room number should represent the actual room number physically installed on the door. If the room is not
specifically marked, a fictitious room number is assigned on the AutoCad plans.
5) Use the same numbering sequencing for repeating rooms on every floor. For example, if on the first floor, in
the elevator core area, there is a repeating toilet (room 115) and janitor’s closet (room 116), and then on the
second floor these same rooms would be labelled as rooms 215 & 216.
6) Leave some gaps between room numbers so that when a future renovation takes place we have spare room
numbers that can be utilized.
7) For a large room (room 328) that is sub-divided into smaller rooms, then those room numbers are labelled as
(room 328A), (room 328B), (room 328CA) etc… This technique is also applied to open areas such as
libraries. They are sub-divided; by room use such as stack areas, reading areas, circulation counter, reference
areas etc… Please see Figure 1 below.
8) For all new wing additions to existing buildings, follow the existing room number sequencing.
9) For all new floor additions or major renovations to existing buildings, follow the existing room number
sequencing.

Room Number Guidelines
10) Hallways on the first basement level are to be numbered as B1-HALL1, B1-HALL2, and B1-HALL3. Hallways
on the ground floor are to be numbered as 0-HALL1, 0-HALL2, and 0-HALL3. Hallways on the first floor are to
be numbered as 1-HALL1, 1-HALL2, and 1-HALL3. Hallways on the second floor are to be numbered as 2HALL1, 2-HALL2, 2-HALL3 etc…
11) Stairways on the first basement level are to be numbered as B1-STAIR1, B1- STAIR 2, and B1- STAIR 3.
Stairs on the ground floor are to be numbered as 0- STAIR1, 0- STAIR 2, and 0- STAIR3. Stairs on the first
floor are to be numbered as 1- STAIR1, 1- STAIR 2, and 1- STAIR3. Stairs on the second floor are to be
numbered as 2- STAIR1, 2- STAIR2, 2- STAIR3 etc…
12) Elevators are only labelled on the very lowest floor they occur. Elevators are to be numbered only once. In the
majority of cases this would be the first basement floor. Elevators are to be labelled as ELEV1, ELEV2, and
ELEV3 etc… In addition the number for the elevator (i.e. ELEV2) is to be obtained from Facilities Management
since each elevator at McGill has a unique number. Repeating elevators on other floors do not have a room
number but the duct space they occupy is removed from the gross area calculation.
