About BTTOTEK Solutions

BTTOTEK Solutions is an engineering calculation platform for the people who actually price and build projects: site engineers, quantity surveyors, contractors, architects and property investors. We turn the spreadsheets that live on every site office laptop into reactive, auditable tools that anyone on the team can run.

Every formula follows standard IS-code practice and widely accepted trade conversion factors. Where local variation exists — bigha size, state stamp duty, market rates — we expose the assumption as an editable input instead of hiding it.
