Brick Calculator: Wall Bricks, Blocks, Cement and Sand
Wired White v1 Estimate bricks or AAC blocks, cement bags and sand after deducting openings. Compare mortar, wall weight and your material costs with regional sizes and custom dimensions.
Civil and construction
Site and building engineering: concrete, steel and brick quantities, bar bending schedules, house frame loads, retaining walls, road curves, earthwork volumes and plot areas. Each calc shows its method and the public sources behind it; a structural design still needs a licensed engineer.

Retaining Wall Calculator: Overturning, Sliding and Bearing
Wired White v1 Check gravity and cantilever retaining walls for sliding, overturning and base bearing. Compare Rankine or Coulomb pressure, surcharge, groundwater and uplift.
Bar Bending Schedule Calculator & Steel Bar Weight
Wired White v1 Calculate steel bar weight and schedules for slabs, beams and columns. Get steel lengths per run, run/link counts, shape sketches and mass by diameter with editable detailing allowances.
Cement, Sand and Aggregate Calculator for Concrete
Wired White v1 Estimate cement bags, sand, aggregate and free water for small nominal-mix concrete pours. Includes geometry, wastage, loose-volume recipes and metric/US results.
Plot Area Calculator from Sides and Diagonals
Wired White v1 Calculate irregular land area from side lengths and internal diagonals using Heron's formula. See a to-scale plot, check an extra diagonal, and convert to metric, US and local units.
Cut and Fill Calculator: End Area vs Prismoidal
Wired White v1 Compare average end area and prismoidal earthwork volumes, include shrink and swell, and inspect a mass-haul diagram. A second mode estimates a building pad from a nine-point grid.
Road Curve Setting Out: Tangent Length, Chainages and Offsets
Wired White v1 Calculate circular curve elements, PC/PT chainages and peg tables by exact Rankine deflections, tangent offsets and long-chord offsets. Choose 20 m, 30 m or 100 ft stationing.
House Frame Column Load Calculator: Slab to Footing (Preliminary)
Wired White v1 Trace slab, wall and beam loads through a house column grid. Estimate storey axial loads, short-column steel demand and footing area for preliminary planning.
