Burj Structural Estimator

Burj Structural Estimator is a standalone, offline-first engineering calculator and materials estimator designed for site engineers, construction consultants, and builders. It helps calculate raw materials and estimate concrete, steel, and brick quantities directly on construction sites, eliminating the need for manual reference charts or internet access. Main Features: 1. Concrete Volume Estimator: - Calculate wet and dry concrete volumes based on user-entered length, width, and depth/thickness. - Supports both metric (meters) and imperial (feet and inches) unit inputs. - Automatically estimates the required cement bags (50kg standard), sand volume, and gravel volume based on selected mix ratios. 2. Steel Rebar Weight Estimator: - Calculate unit weight and total weight of steel reinforcement bars in kilograms and metric tons. - Supports standard diameter selections (6mm, 8mm, 10mm, 12mm, 16mm, 20mm, 25mm, 32mm, 40mm) or custom bar diameters. - Computes weight based on total length entered in meters or feet. 3. Brick & Mortar Calculator: - Estimate the total count of bricks, wet/dry mortar volume, cement bags, and sand volume. - Enter custom wall dimensions (length, height, thickness) and mortar joint width. - Choose between standard brick size presets (GCC, modular, US/UK) or custom brick dimensions. 4. Concrete Mix Design Helper: - Select standard presets for nominal concrete grades: M5, M7.5, M10, M15, M20, M25. - Displays descriptions, nominal strengths, and recommended structural applications for each grade. - Computes raw cement bags, dry sand, dry gravel, and mixing hydration water in litres for any volume. 5. Saved Calculations Log: - Save estimation runs locally with custom project titles. - View, search, and delete saved logs offline. - Examine detailed parameters and computed results inside details modal. 6. Rebar Weight Reference Chart: - Quick on-site reference table displaying unit weights (kg/m, lbs/ft) and standard 12-meter bar weights for diameters Ø6mm to Ø40mm. 7. Onsite Unit Converter: - Convert engineering units for Length (m, ft, in, mm), Area (m², ft², in²), Volume (m³, ft³, Liters, Gallons), and Weight (kg, lbs, tons) instantly. 8. Engineering Formulas Reference: - Reference equations for concrete dry compaction factor (1.54 multiplier), steel rebar weight (d²/162.28), brick wall volumes, and hydration water values. 9. Offline Privacy Policy: - A dedicated local page explaining that the application runs completely offline, requests no device permissions, and transmits no user data.
