It's your worst nightmare: You've submitted a bid, it's been
accepted, and then you find out there was a mistake in your
estimate or that your bid was based on a subcontractor's
A recently decided legal case in California shows just how
messy things can get when such a bidding error turns up. In
this instance, after the prime contractor's bid was opened and
accepted — but before the contract papers were signed
— one of the subs told the prime contractor there was
a huge mistake in that sub's bid.
Right to Amend a Bid
California state law gave the prime contractor in the case the
right to amend his bid to the customer in the event of a
mistake. Nevertheless, the prime contractor chose not to do so.
(The job was a municipal project and he would have had to
forfeit a sizeable bid bond if he backed out after his bid was
accepted.) Instead, he went ahead and signed the contract
without correcting the mistake, and then he started the
At that point, the sub said, "Hey, I told you there was a
mistake in my bid before you signed the contract, and I'm not
going to do the work at that price." So the prime contractor
hired someone else to do the work, but he ended up paying a lot
more than the original bid price.
After the work was finished, the prime contractor sued the
original sub for the extra money that the work had cost. The
prime contractor's lawyer said, "We relied on the figures in
the sub's bid when we put our bid together. What's more, the
sub knew we would be relying on his bid. The law calls that
detrimental reliance, and what it means is that the sub created
this problem, so he should pay the difference between what he
bid and what the work actually cost."
The sub's lawyer responded, "What do you mean, the sub created
this problem? You knew those figures weren't reliable before
you ever signed that contract."
The lower court agreed with the sub and said that once the
prime contractor knew there was a mistake, he was no longer
entitled to rely on those figures.
Sounds reasonable so far, right? But here's where the legal
hair-splitting comes in: The prime contractor appealed the
lower court's decision and the Court of Appeals ruled in the
prime contractor's favor.
The higher court ruled that even though state law allowed the
prime contractor to correct his bid, it did not require him to
do so. So even though the prime contractor knew there was a
mistake, he did not have to correct it.
In effect, the Court of Appeals was saying that detrimental
reliance occurred at the moment the contractor submitted his
bid; therefore, the subcontractor was bound to honor his price
from that point forward. Not honoring it would be detrimental
to the contractor.
According to the Court of Appeals, the only question that
mattered was this one: Should the prime contractor have
suspected that there might be a mistake in the sub's figures
the first time the prime contractor saw them? In other words,
was the sub's bid price just too good to be true?
If the prime contractor should have suspected a mistake, then
it was unreasonable for him to rely on the sub's bid.
Unfortunately for the sub, the court also ruled that if it was
reasonable for the prime contractor to rely on the sub's bid,
the sub had to pay.
So the higher court sent the case back to the lower court to
make a determination about how reasonable it was for the
contractor to have relied on the original bid. The lower court
has not yet made that determination.
Moral of the Story
Clearly, you can't be too careful when you write your bids. If
you're a contractor and a sub gives you a price that seems too
low (or is significantly lower than prices from other subs), do
not rely on it without first calling him to make sure that it's
correct and he will honor it.
And if you're a sub, and a contractor relies on your bid to
get a job — and will be significantly damaged if you
do not honor it — keep in mind that you may be
required to honor it even if you don't want to and haven't
Those are the first two lessons. But I can think of at least
two more that you should take away from this case:
First, think how much better off the subcontractor would have
been if he had included a clause in his bid that allowed him to
amend the bid in the event of a mistake. You don't need a state
law authorizing that kind of clause if both parties agree to
Second — and this is probably the most important
lesson of all — one guy wins and the other guy loses
in a lawsuit, but so what? The reality is that they both lose.
Even the winner loses money — in unreimbursed legal
fees, in time, and in the delay in collecting what he had
coming from the original contract. These guys should have
worked out a deal long before this ever got to court.
Yes, it's painful to compromise when you're right and the
other guy's wrong, but we're not talking about life-and-death
constitutional principles. It's just business. When there's a
controversy, you need to solve it as quickly as possible so you
can get back to running your company.
