Tenant standards, checked before the corridor is built

The tenant has its own pathway and conduit standard. We found the difference after the corridor was built.

Every tenant brings a standard of its own for pathways, conduit, containment and labelling, and it rarely matches the base-build spec line for line. Criad loads the tenant standard beside the spec, shows where the two disagree, and checks the model against both before the corridor is built, not after.

Every answer cites its source. People decide.

How it works

Ask. Inspect. Verify. Publish.

1

Ask

A plain-language question.

"Where does the tenant standard differ from our spec on this corridor?"
2

Inspect

The full blast radius, on the model.

The pathway on the model, end to end, with the containment, conduit and fixings the design shows.
3

Verify

Checked against the governing drawings and specs.

Each requirement in the tenant standard is checked against the spec and the model. Disagreements are listed with both clauses; the governing one is named.
4

Publish

A dashboard, report or register, citations attached.

A departures list per corridor, clause by clause, for the client to settle before the work is priced and built.
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, Hall 2: the containment run is one connected path on the model.

  2. 02

    Each element on it knows the sheet it is drawn on and the clause that limits it.

  3. 03

    A tenant standard is loaded as one more document and ranked against the spec and the code: 360 degrees of bend between pull points (NEC, TIA-569), 200 mm power to data separation for unscreened cables (EN 50174-2).

  4. 04

    The differences are listed, with both clauses, before anything is built.
