What this group solves

Masonry take-off goes wrong over definitions. Brick count depends on wall thickness and joint, from 529 bricks per cubic metre in a 240 mm wall to 552 in a 120 mm wall. Mortar is not simply one minus brick volume — it needs the joint-fill allowance added on top. This group keeps the brick, mortar and block chains separate so one does not contaminate the other.

Secondary structure — tie columns, ring beams, lintels and wall ties — is the most commonly missed quantity, yet it carries a meaningful share of the cost. Tie columns run roughly one per 5 m of wall and one per storey band, lintels take the opening width plus 250 mm bearing each side, and ties go in every 500 mm of height extending 700 mm or a fifth of the wall length, whichever is greater. All of these are editable so you can match the local detail book.

FAQ

How many bricks per cubic metre?
With 240 × 115 × 53 bricks and 10 mm joints: 529 per m³ in a 240 mm wall, 552 in a 120 mm wall, 522 in a 370 mm wall and 518 in a 490 mm wall. The formula is 1 ÷ (wall thickness × (brick length + joint) × (brick height + joint)) × K, where K is twice the number of brick widths in the wall.
How much mortar per square metre of brickwork?
About 0.226 m³ of mortar per m³ of 240 mm brickwork, roughly a 22 mm layer over the wall area. Calculate one minus the net brick volume, then apply a 1.05-1.10 allowance for joint fill. An M5 cement mortar uses about 200 kg cement and 1.15 m³ sand per cubic metre.
What quantities does a tie column involve?
Four: concrete volume, formwork area, longitudinal bars and stirrups. Volume is wall thickness × column width × storey height less the beam depth; formwork is both faces; stirrups are closer together within 500 mm of each end. Tie columns are non-structural, but toothing and wall ties are routinely left out of quotes.
