ConstructionKS-2 vs estimate

What to cut from an act before you sign it

Upload the KS-2 act and the contract estimate. The service finds volumes above the estimate, prices above estimate rates, work outside the estimate, repeats from earlier acts and arithmetic errors — and totals the amount to cut.

The workspace and bots are in Russian.

How the reconciliation runs

  1. 1The act to sign

    An Excel export from estimating software works best — PDF parses worse.

  2. 2The contract estimate

    A local estimate or contract price list: volumes, rates and prices are checked against it.

  3. 3Earlier acts

    Optional. With them volumes are checked across all acts since work began, and repeats show up.

  4. 4Amount to cut

    Each line comes with an amount and its place in the act. Confirmed amounts go to the money log.

What we check

Volumes above the estimate

Including all earlier acts under this estimate.

Prices above rates

The rate in the act vs the rate in the estimate.

Work outside the estimate

Items the estimate doesn’t have at all.

Repeats

Work already closed by an earlier act.

Arithmetic

Errors in a line’s cost and in the act total.

Source of every amount

The act line and the estimate line side by side.
