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.
