Variations with evidence

The change was instructed on site. Proving what it touched, and getting paid for it, took months.

A variation is only as strong as its record. Criad shows what the instruction changed against the contract documents, measures the difference on the model, and keeps the sheet, clause and revision attached, so the claim is a statement of fact and not a negotiation from memory.

Every answer cites its source. People decide.

How it works

Ask. Inspect. Verify. Publish.

1

Ask

A plain-language question.

"What did this instruction change against our contract scope, and how much of it is there?"
2

Inspect

The full blast radius, on the model.

The elements the instruction touches, on the model, with the contract position beside the instructed one.
3

Verify

Checked against the governing drawings and specs.

The difference is measured on the model and checked against the contract drawings and the spec. The governing source is named for each item.
4

Publish

A dashboard, report or register, citations attached.

A variation record: what changed, quantities, the documents that show it, and the date each was issued. People agree the value.
Worked example

One job, start to finish.

Values come from a structured reference campus, not from a client project.

Reference campus
  1. 01

    Reference campus: the contract spec allows a cabinet depth of 0.92 m.

  2. 02

    The instruction asks for 1.0 m: 0.08 m over, on a product shared by 96 cabinets.

  3. 03

    The record shows the clause, the instruction and the elements affected.

  4. 04

    The conversation is about value, not about what happened.
