NEW — Formwork Sheet (Pro) Plan a whole project's shuttering in one place. Build an element schedule and the app derives your ply sheets, battens, walers, ties, props, back-props and a complete scaffold list from it — then tells you the PEAK quantity you actually need to buy, not the cumulative area you bill. Includes cycle planning, de-shuttering sets and eight validation checks that flag a take-off before you issue it. Export a branded PDF, push quantities to a BOQ, or send a row straight in from any shuttering calculator. NEW — Brick Size Library Your own brick and block sizes, saved once and used everywhere. Region-aware seed catalogue, a default per brick/block type, and auto-fill across all 24 brickwork calculators. Backed up and synced with the rest of your data. Open it from Settings or the Brick Work page. NEW — False ceiling calculators Gypsum Ceiling, POP Ceiling and Grid Ceiling, with section and plan drawings, regional advisories, and material rates stocked for all six regions. IMPROVED — Shuttering, redrawn 17 element calculators, each with a new two-view drawing that shows WHICH FACES GET FORMWORK - a footing is sides only, a beam is soffit plus two sides. Tap any field and its dimension lights up on the drawing. IMPROVED — Quantity tab Calculators are now ordered by how relevant they are to your role and region. Nothing is hidden; your favourites still come first.
