  • TMS 402/602 β€” Building Code Requirements and Specification for Masonry Structures
    Guidance on bond types (running, common, stack, flemish) and mortar joint specifications
Formulas Used
  • Wall area: wallArea = wallLength x wallHeight
    Source: Basic geometry
  • Net wall area: netWallArea = wallArea - openingArea
    Source: Standard deduction method
  • Bricks required: bricksRequired = ceil(netWallArea x bricksPerM2 x (1 + wastage/100))

Key Assumptions
  • US modular brick size: 194 x 92 x 57mm (7-5/8 x 3-5/8 x 2-1/4 in) β€” ASTM C216
  • Default mortar joint width: 10mm (3/8 in) β€” TMS 402/602
  • Running/common/stack bond uses ~74 bricks per m2; flemish bond uses ~111 bricks per m2 β€” BIA Technical Note 10
  • Typical wastage allowance of 5-10% for cutting and breakage β€” Industry standard practice
