Bid Validity Period: What You Are Committing To, and What Happens If You Withdraw

When you submit a bid, you commit to your price for a stated period. That commitment is a free option written by you and held by the buyer, and its cost belongs in the price rather than in hope.

What the period is

The bid validity period is stated in the notice, commonly counted in days from the date of bid opening. During it, your bid stands and you cannot withdraw or modify it without consequence.

The consequence is normally forfeiture of the EMD, which is exactly what the deposit secures.

What you are actually committing to

For a works contract, holding a price for several months means holding it through:

• Movements in steel, cement, bitumen and fuel
• Wage movements
• Changes in your own capacity, as you win or lose other work
• Changes in your working capital position

None of these are in your control, and all of them can move against you.

This is why a bid priced with no margin for movement is a bid you may want to withdraw from, and wanting to withdraw is precisely the situation the validity period is designed to prevent.

Pricing the exposure

The honest treatment is to include the cost of holding the price. Where the contract also has no price variation clause, the exposure extends through the construction period as well, and the total commodity risk you are carrying is substantial.

Two practical approaches:

• Hold quotes from suppliers with matching validity where possible, which transfers part of the risk
• Price the residual risk explicitly as a line in your build-up rather than absorbing it into margin

How to price a government tender covers where this sits alongside the financing costs.

Extension requests

Evaluation frequently runs longer than the validity period, and buyers then ask bidders to extend.

An extension request is a decision, not a formality:

Extending keeps you in contention at your original price, for longer, with the same exposure continuing.

Declining generally takes you out of contention. Whether it also risks your EMD depends on the notice's wording, and this is worth reading carefully rather than assuming. Declining to extend beyond the original committed period is not usually the same as withdrawing during it, but the position is set by the document.

Where a buyer asks you to extend and also asks you to extend the EMD instrument's validity, both need action, and the bank guarantee or FDR extension takes working days.

When declining is right

Where materials have moved substantially, where you have won other work and no longer have capacity, or where the contract at that price is no longer one you want, declining is a legitimate commercial decision.

The mistake is to extend passively, out of a reluctance to say no, and then find yourself awarded a contract you did not want at a price that no longer works. That leads to either performing at a loss or failing to execute, and the second triggers forfeiture and possible consequences beyond it.

Extend deliberately, or decline deliberately. Do not drift.

Validity and the EMD instrument

Where EMD is furnished as a bank guarantee, its validity generally has to exceed the bid validity by a stated margin, so the buyer can invoke it if needed at the end of the period.

Practical consequence: an extension of bid validity usually requires an extension of the guarantee, which requires the bank, which takes time and costs commission. Factor both into the decision. See bank guarantee, FDR or insurance surety bond.

Tracking it

Record the validity expiry against every live bid. It tells you when your exposure ends, when to expect either an award or an extension request, and when to chase an EMD refund if neither has arrived.

Avsar tracks validity periods and EMD instrument expiries against every bid you are running. See the treasury module.
