Electrical Calculations — a complete new section, 69 calculators. LOAD CALCULATION Size a whole structure's electrical load in one place: connected load, maximum demand, design current, phase balance and the sanctioned load figure your utility asks for. Export the sheet as Excel or PDF with your company details on it. CABLES & CONDUIT Cable sizing, voltage drop, maximum run length, cable weight and drum counts, conduit fill, cable tray sizing and support quantities. PROTECTION & MOTORS Breaker and MCB sizing, RCD/RCCB selection, fault level, motor full-load current, starter and contactor selection, power factor correction. LIGHTING Lumen method fixture counts, illuminance checks, fixture spacing, lighting power density and street lighting layouts. EARTHING & LIGHTNING Earth conductor sizing, electrode resistance, multiple electrodes, earth pit materials and lightning protection. POWER SOURCES Transformer sizing and loading, DG set sizing and fuel cost, UPS and battery banks, solar PV capacity, panel counts and off-grid storage. QUANTITY & BOQ Wiring point, wire, conduit, termination and distribution board estimators that feed straight into your BOQ. CONVERTERS Electrical units, conductor size (mm² / AWG / kcmil / SWG) and illuminance (lux / foot-candle). Everything follows your region — India, USA, Canada, Australia, Europe and the Gulf each get their own voltages, demand factors and standard breaker ratings. ALSO NEW • Metal Library — alloy and section reference data • Material Library with specification lookup • New BOQ sheet flow and house-cost standards • Region-accurate concrete grade data • The Quantity tab now orders itself by your role and region • Calculator inputs sit two per row, so there's less scrolling • A What's New screen, so you can see each update at a glance FIXES • Concrete quantities showed NaN after changing the grade • The keyboard's Next could skip a field in the metal calculators • PDF export could hang on the web • Grid and layout fixes on wide screens Electrical sizing results are indicative and should be verified by a licensed electrical engineer against your local code.

NEW — Formwork Sheet 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 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.
