A notice is valid or it is nothing
This is the part that catches good projects with good arguments. A notice does not become valid because everyone knew about it. It becomes valid because it was served by the contract’s method, to the contract’s addressee, within the contract’s time.
FIDIC 2017 made this explicit and unforgiving: a Notice must identify ITSELF as a notice, cite the clause it is given under, and travel by the agreed channel. An email that describes a problem in detail, to the right person, inside the window, is not a notice if it does not say it is one. And the courts have been consistent about this for a very long time — actual knowledge does not cure defective notice. The other side knowing perfectly well what happened is legally irrelevant if you did not tell them in the manner you agreed to tell them.
Which means the question “is email a valid notice?” has exactly one correct answer: only if the contract says so, and only to the address the contract names. Not the project manager’s personal address. Not the WhatsApp group. The addressee in the contract, by the method in the contract.
What correspondence discipline actually is
The personal-inbox silo is a single point of failure that everybody accepts. The project engineer resigns. IT deactivates the mailbox on a ninety-day policy nobody on the project was consulted about. And three years of instructions, agreements, clarifications and understandings — the entire operational memory of a workstream — go with them. Correspondence addressed to the PROJECT, filed in a register, survives people. Correspondence addressed to a person does not, and it does not fail gradually; it fails completely, on a date set by an HR process.
Letters carry positions. Email carries coordination. Do not confuse them. In GCC consultant culture, positions are taken by numbered letter — sequentially numbered, referenced, logged in a correspondence register with an action-by date against each one. That is not bureaucratic ceremony; it is how a position becomes findable, attributable and dated. Email is excellent for coordination and terrible for positions, because it has no sequence, no register, and no natural way to tell the important message from the four hundred around it.
Discovery cost scales with custodians, and that is a decision you make years in advance. Producing documents in a dispute runs at eighteen to twenty thousand dollars a gigabyte, and roughly three-quarters of that is human review. That number is from 2012 and it is still the standard citation. But notice what it means operationally: fifteen personal inboxes, each holding overlapping copies of the same threads, is fifteen custodians to collect, de-duplicate and review. One project record is one. The cost difference is not marginal.
Incoming correspondence carries clocks, and clocks do not live in inboxes. A determination to respond to. A consent to give or withhold. A submission deemed accepted if you say nothing. These arrive as email, and an email is an object that sits still — it does not remind you, it does not escalate, and it does not care. Anything with a contractual response window belongs on a deadline board with an owner against it, not in a folder that somebody intends to look at.
What it costs to run correspondence as chat
A meritorious claim dies on formality — the right facts, the right timing, the wrong channel or the wrong addressee — and no amount of the other side having obviously known cures it.
A key person leaves and takes the record with them. Nobody notices for months, because the absence of a document is invisible until you go looking for it.
And a dispute begins. Fourteen months, on average, of people reading your correspondence. Except it is not one correspondence: it is fifteen inboxes, half-overlapping, at nearly twenty thousand dollars a gigabyte to produce — and the position your consultant took in 2024 is in there somewhere, unless the person who received it has left.
How Zepth runs correspondence
Mail addressed to the project rather than to people, threaded and held in registers — so the record survives resignation, reorganisation and the ninety-day mailbox policy. Numbered letters with references and action-by dates, which is how a position stays findable.
Response deadlines tracked on a board rather than intended in an inbox. And every piece of correspondence linked to what it actually references — the RFI, the instruction, the claim — so the thread and the record are the same object rather than two systems and a gap.
