CPM 317: Numbering Rooms and Other Areas in University Facilities
To establish a uniform approach to the numbering of rooms and other spaces in university facilities
Consultants, design project managers, construction administrators, design coordinators, and facilities analysts
Any facility that ASU is maintaining a property presence within
During the development of working drawings, rooms and other spaces in facilities shall be numbered in accordance with the guidelines below. Each submission of numbered floor plans is reviewed by the user group for the accommodation of their management needs and by University Facilities Records Management (UFRM) for conformance with the room numbering guidelines. In an extraordinary situation only, an alternative numbering scheme may be approved with sufficient justification. UFRM must approve any alternative numbering scheme before it is used. If an alternative numbering scheme is approved, UFRM may require the consultant to prepare a room numbering schedule that provides an approved room number for each numbered room on the working drawings. The room numbering schedule must be included on the working drawings. All room numbering controversies are resolved by UFRM
These room numbering guidelines were established to assure that the numbering of spaces in university facilities will guide people to their destinations, facilitate management, and ensure control and consistency from facility to facility. Because of the infinite number of possible facility designs, i.e., shapes, levels, etc., it is impossible to describe a system that will cover all alternatives. Therefore, after careful consideration, it may be necessary to deviate from these guidelines.
Identification of Floors and Levels in a Facility
The main or first floor of a facility is identified as the location of the major pedestrian entrance level and should be at the same level as the outside grade or the lower level of a split-level entry. For example, the main level or floor would be 100 series numbers with successive levels above being 200, 300, etc. Floors below the main level would be L1-00, L2-00, L3-00, etc. Levels such as penthouse, mezzanine, etc., or any part thereof, will be a part of the total facility number system.
Consistent Room Numbering
Room numbers in a facility must follow a consistent room numbering system that provides information and a logical sense of direction and continuity. Room numbering should facilitate pedestrian movement within the facility. Each room or space in a facility must have a unique room number.
Room numbering should reflect a general location within the facility, one that relates to circulation elements and is consistent from floor to floor. Every attempt should be made to “stack” similar numbers by floor levels so that Room 120 is in the same relative position in the facility as are Rooms 220, 320, and so on. Interior graphics should also be taken into consideration, assigning ranges of numbers to facilitate directional signs.
Room Numbering and Pedestrian Movement within a Facility
The location of the main entrances, secondary entrances, interior stairs, and elevators are the keys to pedestrian movement within a facility. Room numbering should be consistent, compatible, and relative to key movement elements at all levels.
Room numbers should indicate a consistent orientation from a public circulation element within a facility such as an exterior entrance, stair, or elevator. They should indicate the same sense of direction (increasing or decreasing) from the primary circulation element, for example, the main elevator lobby.
Assignment of Room Numbers
|level||primary room number||room number suffix|
|sample room number||4||1||9||A|
|First||The first digit is used to identify floor levels above nine (e.g., 1025, 1130, etc.) and to identify lower levels (e.g., L1-00, L2-00, L3-00, etc.). Wing prefixes should only be used if there are too many rooms on a floor to allow rooms to be numbered without using a wing prefix. If used, the wing prefixes may be separated from the room number by a hyphen (-) on the working drawings and on room number signs.|
|Second||The second digit is used to identify floors
between level 1 (ground level) and level 9 (e.g., 133, 722, etc.)
and to identify levels below grade (e.g., L1-01, L2-35, etc.).
Below Grade Level Prefixes
|Third and Fourth||The third and fourth digits (01 through 99) are primary room numbers for rooms on the same level that are entered from a public circulation corridor. Mechanical rooms, janitorial areas, utility closets, and public restrooms are included in the room number sequence with a facility service space suffix.|
|Fifth and Sixth||An alpha or numeric character is used to number rooms that are not entered from a public circulation corridor.|
Although janitorial areas, public toilets, mechanical rooms, and utility closets are numbered in sequence with other room numbers on a floor, a facility service suffix is added (e.g., 244M1, 352U1, etc.). To conserve on the quantity of primary room numbers used for facility service rooms, adjacent service rooms may use the same primary number with distinguishing suffixes (e.g., an adjacent restroom and janitor closet may be numbered 244M1, 244W1, and 244J1).
Alpha suffix characters for numbering facility service space:D
|Alpha Suffix Character||Building Service Space|
|C||Public circulation corridors, including building entries|
|M||Men’s public toilets|
|P||Pipe or duct chases|
|T||Unisex public toilets|
|U||Mechanical rooms and utility closets|
|W||Women’s public toilets|
