Manage an engineering change

Run a design or engineering change through proper control: raise it with its reason and risk, clear the technical questions it opens by RFI, and carry any cost or time impact into a change order.

How it works, step by step

3 steps across the platform - what you do at each one, and why it matters.

1

Raise the change under control

Management of change

Open a management-of-change record for the proposed change and state plainly what is changing, why, and the safety, operational and design risk it carries. Route it for review before anyone touches the work.

Why: Engineering changes that skip a control step are how a well-meant fix ends up unsafe or non-compliant. The record is the proof the risk was looked at and the change was authorised, not just done.

Clear the technical questions

RFI

Raise an RFI for each open technical question the change throws up, dimensions, interfaces, specification, and get the designer to answer in writing before the detail is fixed. Keep every RFI tied back to the change.

Why: A change built on an assumption is rework waiting to happen. Getting the answer on the record, from the person responsible for the design, is what stops the same question being argued again on site.

Carry the impact into a change order

Change orders

If the change moves cost or time, raise a change order that captures the priced impact and the programme effect, linked back to the change record. If the impact is genuinely nil, record that too.

Why: The engineering side can be closed and still leave the money open. A change order is what turns an authorised change into an agreed cost and a moved date, before it quietly becomes your problem.
