Tenders and Auctions

01

The deadline is the server's

A bid that arrives one second past the hour is recorded as late, by exactly how many seconds, with the server's own time in the refusal. It is never opened and never evaluated — and it is never deleted either, so "we submitted on time" is answered with a record instead of an opinion. The countdown on the bidder's screen is decoration; the clock that decides is here.

02

Two officers, or nothing opens

The tender's master key is split across the named opening officers, and each officer's share is wrapped under a key derived from a passphrase the system never stores. One officer cannot open a bid. Neither can an administrator holding the database. And we say the limit out loud: on a self-hosted database, somebody with the database and an officer's passphrase could — cryptography narrows that to a conspiracy, and only an HSM removes it.

03

A question from one bidder is answered to all

The default is publication, to every invitee, anonymised. A private answer is still possible — sometimes the question really is about one bidder's own paperwork — but it is recorded as private and it appears in the audit trail, because answering one bidder and not the others is the commonest way a tender is quietly rigged, and the cure is that doing it leaves a mark.

04

The unit rate governs

Bidders make arithmetic mistakes on a bill of eight hundred lines. Every extension is recomputed from the rate and the tender's own quantity, each correction is itemised and shown to the bidder, and the corrected figure is what is compared. Provisional sums and tax come out, currencies convert at the rate date fixed in the tender rather than at today's rate, and alternates are their own column instead of being merged into the base.

05

Scored blind, then agreed out loud

Each evaluator marks against the published weighted criteria and cannot see anybody else's marks until every mark is in — anchoring is how a committee's judgement is quietly captured by its loudest member. Then the consensus session records the agreed score and the reason where evaluators differed, and both the individual marks and the consensus survive in the file.

06

The window a losing bidder can still win in

A government award sets a standstill, and until it runs out the award cannot be handed to a purchase order or a contract — the system refuses, with the date. Signing inside the only window in which a decision can still be undone makes every challenge procedure decorative. The losers' bid bonds are released the moment the award is made, because until somebody releases them the bidder is still paying a bank.

07

A مزايدة is not a مناقصة with the sign flipped

Arabic separates what English does not: a competition to supply and a competition to acquire. A government sells land, vehicles, scrap and concessions as routinely as it buys, so direction is one of the six axes of a tender rather than a flag on the auction — and a reverse auction with anti-sniping extensions, a minimum decrement and a hidden reserve is the same engine with the comparator inverted.
