Construction Calculator & Plan

30 construction calculators plus full project management — free, offline, no ads. ConstructPro sizes your concrete, rebar and foundations, estimates the job cost, then tracks the budget, tasks and permits for the project you just estimated. Free. No ads. No subscription. No daily calculation limits. 🏗️ WHY BUILDERS CHOOSE CONSTRUCTPRO Most construction calculators stop at the number. Most construction management software is priced for head office. ConstructPro does both, for free — built for the person standing on the slab, not the one in the boardroom. 🔢 CONSTRUCTION CALCULATORS • Cost Estimator — area, grade, labour, contingency and tax • Material Quantity — bricks, tiles, paint and sand • Concrete Mix Design — by volume or bag count • Rebar Calculator — steel weight and spacing • Beam Deflection — simply supported and cantilever beams • Foundation Calculator — bearing capacity and sizing • Load Bearing Calculator — structural load analysis • Seismic Calculator — base shear and seismic loads • ROI Calculator — return on construction investment • Bid Comparison — weighted scoring across multiple vendors • Carbon Footprint — estimate construction emissions 📋 PROJECT MANAGEMENT — WHAT OTHER CALCULATORS DON'T HAVE • Budget Tracker — planned vs actual spend by category • Task Manager — create and monitor tasks with due dates • Gantt Chart — visual project timeline • CPM Scheduler — critical path method planning • Milestone Tracker — planned, forecast and actual dates • Punch List — snag lists with photo attachments • Permit Manager — track permit status and expiry dates • Resource Scheduler — people and equipment bookings • RFI Tracker — requests for information log • Analytics Dashboard — budget, task and milestone metrics • PDF Project Reports — shareable progress reports 🛡️ SAFETY & COMPLIANCE • Safety Checklist — customisable site safety checks • OSHA Compliance — standards reference and checklist • PPE Tracker — personal protective equipment log • Incident Report — record, categorise and export incidents • AI Risk Predictor — on-device advisory risk scoring 📄 DOCUMENTS & REPORTS • Contract Builder — generate and export contracts as PDF • Invoice Generator — create and share invoices as PDF • Progress Report — weekly and monthly progress with photos • Daily Site Log — workforce, weather and activities • Drone Report — aerial inspection log with photos • BIM Viewer — organise and access BIM model links • Document Vault — store and organise project documents 📱 BUILT FOR SITE CONDITIONS • Works offline — calculators and logs run with no signal • Cloud sync — your work backs up automatically once you reconnect • 37 languages supported • PDF export for reports, invoices and contracts • Push reminders for overdue tasks and expiring permits • Optimised for phones and tablets 👷 DESIGNED FOR • General contractors and site managers • Civil and structural engineers • Residential builders and remodelers • Subcontractors and trade contractors • Project managers and quantity surveyors • Safety officers and HSE managers 🔒 PRIVACY Project data is stored locally on your device, or synced to your personal cloud storage when you sign in.
