BuildTally:BOQ & Cost Estimate

From dimensions to a professional construction estimate and Bill of Quantities (BOQ) in minutes — even without internet. BuildTally is an offline-capable construction estimating and Bill of Quantities (BOQ) app built for self-build homeowners, small contractors, fundis, site supervisors, and diaspora builders. It bridges the gap between basic pocket calculators and complex quantity-surveying software. MEASURE IT. PRICE IT. BUILD THE BOQ. Stop guessing material requirements or getting caught off-guard by supplier price shifts. Whether you are building a four-bedroom maisonette, casting a perimeter boundary wall, laying foundation concrete, or installing mabati roofing, BuildTally turns your building dimensions into organized procurement lists and client-ready BOQ documents. ════════════════════════════════════════ KEY CAPABILITIES & TOOLS ════════════════════════════════════════ 1. PRACTICAL CONSTRUCTION CALCULATORS • Concrete Slab & Foundation: Calculate cubic metres (m³), cement bags (50kg), river sand (m³), and crushed ballast (m³) with standard mix ratios (1:2:4, 1:1.5:3, 1:3:6) and customizable waste margins. • Block & Stone Walling: Estimate 200mm/150mm machine-cut concrete blocks or Ndarugu quarry stones, mortar volumes, and sand/cement requirements. • Reinforcement Steel (Rebar): Calculate total kilograms and 12-metre commercial bar lengths for Y8, Y10, Y12, and Y16 rebars including binding wire. • Roofing & Framing: Calculate Box Profile G30 and Corrugated G32 mabati sheets, ridge caps, roofing nails with rubber washers, and cypress timber rafters (2x4, 2x2). • Finishes & Flooring: Calculate ceramic floor and wall tile boxes, tile adhesive bags, and 20L emulsion/undercoat paint containers. • Labour Estimator: Estimate worker-days from physical surface areas and local daily fundi/casual rates. 2. KENYA RATE LIBRARY 2.0 (47 COUNTIES) • Benchmark Pricing: Pre-loaded with benchmark rates for major Kenyan construction materials and suppliers (Bamburi, Ndarugu, Devki, Mabati Rolling Mills). • 47 County Pricing Multipliers: From Nairobi, Kiambu, and Machakos to Mombasa, Nakuru, Kisumu, and rural regions, prices adjust based on transport and local availability. • Custom Rates Mode: Building outside Kenya? Switch to international mode for custom rates in Uganda (UGX), Tanzania (TZS), or USD. • Full User Sovereignty: Override any material rate globally or for a specific project. Add your own custom materials with custom units and baseline rates. 3. RUNNING BILL OF QUANTITIES (BOQ) WORKSPACE • Add calculation results directly to a running project BOQ. • Organize estimates by construction phases: Foundation, Walling, Roofing, and Finishes. • Insert manual line items for site works, transport trips, plumbing allowances, or subcontracting. • Apply contingency buffers (e.g. 5%–10%) and inspect material vs labour cost breakdowns. 4. CLIENT-READY SIGNED PDF EXPORTS • Generate professional, branded PDF estimates with your company name, client details, estimate ID, and signature lines. • Share directly via WhatsApp, email, or print on-site without internet access. • Clean, unwatermarked documents ready to present to homeowners, banks, or site foremen. 5. OFFLINE-FIRST & PRIVATE BY DESIGN • No mandatory accounts or logins. • No project data or client quotes are ever uploaded to cloud servers. Everything stays on your local device. • Export and import portable JSON backups anytime. ════════════════════════════════════════ OFFICIAL DISCLAIMER ════════════════════════════════════════ BuildTally provides approximate cost estimates and material quantities based on published Kenyan market averages.
