Inputs
Start from a job walk or bring your own — historical estimates and models, current plans and specs. The fleet organizes your inputs and prepares the estimate.
DEFENSIBLE CONCEPTUAL ESTIMATING · PRIVATE BETA
For preconstruction teams who have to defend a number before design is done. Buildonto turns estimating history into an explainable forward estimate and a cost-loaded system forecast. Every assumption keeps its basis, source, and approval context.
THE COMPOUNDING LOOP
Start from a job walk or bring your own — historical estimates and models, current plans and specs. The fleet organizes your inputs and prepares the estimate.
Approve, revise, or send back. Every decision is logged, and a truth meter tracks quality so every quantity is counted.
Overlay the site plan and generate a conceptual model with quantities, cost, and assumptions.
