Most schedule loss is waiting for answers.

Answers wait on information held in different systems. Criad connects the drawings, specs, model, programme and procurement of the build, so the answer and its evidence are in the meeting.

Cost and the readiness date

Where the date and the margin go

You carry the facility readiness date and the cost of reaching it. Every open question ends one of two ways: pulled back to the date, or a change to the date and the price that has to stand on its evidence. A change assessment that takes weeks, a revision found after the work is done, an RFI that comes back with a question: each one is time on the critical path with nobody building and nothing to put in front of the client.

Two outcomes, both defensible. The date holds where the knock-ons can be absorbed; where they cannot, the change to the date and the price carries its evidence.

What we hear most

Four issues, in your words.

01

A design change notice lands. Finding everything it touches, and pricing it, takes weeks.

02

A new revision landed. Someone is still building to the old sheet.

03

The RFI went out without the evidence, so it came back with a question.

04

The take-off was right on the day it was done. The model has moved since.

Use case

One change, every knock-on, one decision

A design change notice lands. Finding everything it touches, and pricing it, takes weeks.

One change is never one change. Criad shows everything a requested change touches and checks it against the governing drawings and specs. Not an AI making the call: every knock-on and its evidence, in front of the person who decides.

Ask

A plain-language question.

"The client wants a deeper 1.0 m electrical cabinet. What does that change touch?"

Inspect

The full blast radius, on the model.

96 cabinets across 6 halls light up: one shared product, one long-lead order.

Use case

Sequencing and work zones you can check

The master schedule says which month. It does not say which crane, which zone, or which trade has to be out of the room.

Heavy plant lifts, live electrical work and mechanical installs cannot share a space or a week. Criad links each work package to the elements and the zone it works in, so a proposed sequence can be checked on the model: what is in the way, which zone is live, which room needs a permit, and which trade is waiting on which.

Use case

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.

Use case

Revision guard

A new revision just landed. What changed, and who is still building to the old sheet?

Every element drawn on that sheet is known, so the change list writes itself: what moved, what it affects, who needs to know. Before anyone builds to the old sheet.

Use case

Submittal review at scale

Submittals arrive every week, each one checked by hand against a spec nobody has time to reread.

Each submittal is linked to the elements it covers and the clauses that govern them. Criad checks the proposed product against the clause and the space it has to fit, and shows the reviewer what passes, what fails and what the spec does not say. Approve once, and every unit of that product updates.

Use case

Long-lead orders tied to the design

The order was placed months ago. The design has moved since, and nobody has checked the two against each other.

Long-lead equipment sets the energise date, and lead times run to months. Criad links each order to the elements it covers, the clause it was specified under and the revision it was placed against, so a design change that touches an order shows up when the change is proposed, not when the equipment arrives. When a substitute product is offered to beat a lead time, it is checked against the client standard before it is ordered.

Use case

RFI with evidence

Two documents genuinely disagree. Now what?

Where authority alone cannot settle it, Criad drafts the RFI with the clauses, sheets and measurements already attached, so the question arrives ready to answer.

Use case

Take-offs that refresh

The take-off was right on the day it was done. The model has moved since.

Counts are read straight from the model, and every item is linked to its spec and package. When a revision lands, the take-off is run again, not redone.

Tender pack review

The tender pack is hundreds of files. The bid team has days to find what is in it and what is missing.

The pack comes in as it is: drawings, specs, schedules and the model. Criad lists the requirements with their sources and checks the ones that can be measured. Your team decides whether and how to bid.
