Construction Calculators: Material Estimation & Structural Design

The Brick & Block Calculator counts the number of bricks or CMU blocks needed for a wall given its dimensions, mortar joint size, and waste allowance. The Mortar Quantity Calculator estimates the volume of mortar for brickwork, blockwork, and stone masonry. The Tile Quantity Calculator adds the required number of tiles for floors and walls including cutting waste — specify tile size, area, and waste percentage for a precise order. The Plaster Quantity Calculator estimates cement plaster materials for walls and ceilings at a given thickness and mix ratio. The Drywall Calculator computes the number of plasterboard sheets needed for a room, accounting for door and window openings.

The Steel Reinforcement Calculator computes the weight of rebar from bar diameter, spacing, and length — output in kg or tonnes, ready for BOQ submission. The Precast Volume Calculator estimates the concrete volume and mass of precast elements such as wall panels, floor slabs, and staircase flights. The Staircase Calculator determines the optimum riser and tread dimensions for a given floor-to-floor height. The Retaining Wall Calculator provides preliminary design checks for gravity and cantilever retaining walls against sliding and overturning. The Warehouse Floor Load Calculator checks whether an existing or proposed industrial floor slab can sustain specified racking and forklift loads.
