Long and narrow corridors creating orientation difficulties.

 
 

 

 
 

2. PLANNING PRINCIPLE

 
 

To provide well-dimensioned corridors to facilitate the passage
and maneuvering of a wheelchair.

 
     
  3. DESIGN CONSIDERATIONS  
  3.1 General  
 

Wide corridors are useful for wheelchair users, service equipment, high traffic areas, etc.

 
 

3.2 Width

 
 

The unobstructed width of a low-traffic corridor should not be less than 0.90 m. This also allows maneuverability in 90 turns (fig. 1).

 
 

The unobstructed width of a public corridor should not be less than 1.50 m. The recommended width is 1.80 m (1) (fig. 2).

 
 

To allow maneuverability in 180 turns, the minimum circulation space should be as shown in figure 3.

 
 

The corridor width should allow maneuverability through the doors located along its length (fig. 2) (fig. 4).

 
 

3.3 Obstructions

 
 

Obstacles protruding into the corridor, such as drinking fountains or public telephones,should be placed outside the circulation path, in alcoves or cul-de-sacs (fig. 5).

 
 

Overhanging signs and obstacles should be mounted at least 2.00 m high (fig. 6).

 
 

3.4 Surface

 
 

Changes in surface level of more than 13 mm should be ramped.

 
 

Floor surfaces should be non-slip and even. Carpets should be securely fastened.

 
     
  4. EXISTING CONSTRUCTIONS  
 

Narrow corridors should be widened along their full length if feasible; otherwise, passing areas should be located at appropriate intervals along the corridor length.

 
 

The minimum width of the passing area should be 1.50 m and the minimum length should be 2.40 m.

 
 

In highly restricted spaces, the height of an obstacle or sign can be dropped to 1.95 m.

 
  Notes:  
  (1) 1.50 m is the minimum width for two wheelchairs to pass each other or for one wheelchair to make a full turn
