DESIGN & SPECIFICATION CONSIDERATIONS
BRICKWORK DIMENSIONS TABLES – LARGER FORMATS
Brickwork dimensions should be used whenever possible at the design stage to minimise the need for cut bricks.
All brickwork dimensions are then determined by one of 3 conditions.
1. Brick + 2 joints
2. Brick + 1 joint
3. Brick only
CO+ CO
CO-
e.g. door and window openings
brick panel with opposite return end
brick piers or panels between openings
