Construction Planner
Build quick or manual plans and turn checked dimensions into a bill of quantities.
Estimate on site—even offline. BlockToBlock is available on iPhone and Android.
Product
Plan, calculate, price, save and export without relying on a permanent internet connection.
Planning and quantities
Build quick or manual plans and turn checked dimensions into a bill of quantities.
Calculate blocks, mortar, concrete, wall area, mix materials and waste.
Estimate sheets, timber and fixings for pitched, flat, curved and custom roofs.
Costs and logistics
Maintain local items, units, prices and suppliers, then reuse them across estimates.
Add labour, transport, truck capacity, trip cost and delivery assumptions to project totals.
Record private multi-line purchases, receipts, vendors, equipment hire and project expenses on-device.
Records and hand-off
Open, revise, duplicate, search and remove locally saved work.
Share PDF or CSV estimates with project identity, client/site details, cost sections, assumptions and planning disclaimers.
Choose the presentation that fits the team while calculations retain a consistent base.
Interoperability direction
Today, estimators can review and measure local PDF drawings manually. Future CAD adapters may import candidate dimensions or schedules, but every imported quantity must remain traceable and require approval before it affects a BoQ.
Calibrate each page, record reviewed measurements and explicitly accept BoQ candidates.
Extend the existing reviewed CSV/JSON mappings for quantities, prices and estimate hand-off.
Import selected geometry or schedules with validation, provenance and user approval.
Design rule: imported data remains traceable, editable and untrusted until a person confirms it.
Illustrative review simulation
