Approve a change with every knock-on in view

We asked for a change to the cooling units on one page. The knock-ons arrived later, as claims.

One change is never one change. Before you approve it, see what it touches: the product order, the governing drawing, the install plan. The evidence is in front of the person who decides.

Every answer cites its source. People decide.

How it works

Ask. Inspect. Verify. Publish.

1

Ask

A plain-language question.

"We want liquid cooling in Hall 2 instead of the air units. What does that change touch?"
2

Inspect

The full blast radius, on the model.

The 16 units in the hall and the plant behind them light up: 6 chillers, the chilled water header and the hall feeder.
3

Verify

Checked against the governing drawings and specs.

Checked against the mechanical spec. Clearance to the racks falls to 0.55 m against a 0.6 m minimum; the feeder's 3 m/s limit is re-checked for the new flow.
4

Publish

A dashboard, report or register, citations attached.

A change assessment: verdict, every knock-on and the governing clauses, citations attached.
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 client asks for liquid cooling in Hall 2 instead of the 16 air units.

  2. 02

    In the hall, the deeper units cut the clearance to the nearest rack from 1.45 m to 0.55 m, under the 0.6 m spec minimum.

  3. 03

    In the yard, the 6 chillers were sized for air-cooled halls, and each hall's chilled water feeder was sized to a 3 m/s limit. Both are re-checked before the order.

  4. 04

    The approval goes out with every knock-on listed, and the claims do not arrive later.
