Case study
Building BlockToBlock for Offline Construction Estimating
A mobile construction toolkit shaped around local prices, unreliable connectivity and estimates that can be checked and shared.
The product problem
Construction estimates are often prepared where connectivity is unreliable and material prices vary by market, supplier and delivery route. A useful field tool must preserve the assumptions behind a total rather than presenting a number without context.
What was built
BlockToBlock is available on iPhone and Android and is designed to keep core estimating workflows available without a data connection.
- Wall, roof, block, concrete and mortar calculations
- User-controlled local prices, units and currency
- Saved projects and repeatable estimating workflows
- Labour, delivery, waste and markup inputs
- PDF and CSV export through the device share workflow
A dedicated evidence website
The public BlockToBlock website does more than describe the application. It provides an interactive wall-estimate demonstration, explains calculation assumptions and boundaries, shows application screens and publishes product direction and methodology.
Current evidence boundary
The app and dedicated website demonstrate implemented product capability. This case study does not claim customer savings, revenue or adoption figures that have not yet been verified.
