The Bid Error and the Unbalanced Schedule of Values

Five general contractors bid a lump-sum elementary school for a public school district. The engineer's estimate is $8,850,000; the apparent low bid is $8,412,000 and the second low is $8,690,000. Two days after opening, the low bidder's president sends a letter claiming a clerical error and asking to withdraw: the unit-price extension for 260 tons of structural steel was entered at $2,400 per ton instead of $4,200 per ton, a $468,000 understatement. The bid form states that unit prices govern over extensions and totals. The same bidder's schedule of values shows 9 percent mobilization against 3 percent typical for the district, and a $1.00 per cubic yard unit price for rock excavation with an owner-estimated quantity of 12,000 cubic yards. Award is scheduled in 10 days. Rebidding would take about six weeks, cost the district roughly $60,000 in staff time, and push occupancy by three months.

1. Apply the bid form's unit-price clause and state the corrected total. Is the error a basis for relief from the bid?

Apply the form as written. The bid form makes the unit price govern over the extension and the total. The entered unit price is $4,200 per ton; the extension of 260 tons at $2,400 is the arithmetic error. Corrected:

  • 260 tons × $4,200 = $1,092,000 (versus the extended $624,000)
  • Difference: $468,000
  • Corrected total: $8,412,000 + $468,000 = $8,880,000

That places the bidder third, $190,000 above the second low bidder and $30,000 above the engineer's estimate.

Is this a relief case? The usual test for relieving a bidder of a mistake has three parts: the mistake is material, notice is prompt and in writing, and the evidence of the error and of the intended bid is clear and convincing. Here notice was prompt (two days) and the error is provable from the bid documents themselves - the unit price sits on the form next to the wrong extension. So the bidder has a strong case for relief on the face of the documents.

But the relief question is largely moot for award. Because unit prices govern, the district can evaluate the bid at $8,880,000, at which point it is not low. The district does not have to choose between awarding an erroneous $8,412,000 contract and letting the bidder walk; it corrects the bid and evaluates it. What the district should not do is award at the uncorrected figure, which would guarantee a dispute and a likely default or claim later.

2. Analyze the 9 percent mobilization and the $1.00 rock excavation unit price. Should the district reject the bid as materially unbalanced?

Read the worked answer

Quantify the front-end loading first. On a base bid near $8.4 million, 9 percent mobilization is roughly $757,000 against roughly $252,000 at the district's typical 3 percent - about $505,000 pulled forward into the first months of the contract. That is front-end loading, and its real risk is not the bid price; it is that the district pays out cash far ahead of work in place and is exposed if the contractor fails early.

Then distinguish the two tests. A bid is mathematically unbalanced when unit prices do not reflect reasonable actual costs. It is materially unbalanced when the imbalance is enough that the bid will not result in the lowest ultimate cost to the owner, or gives the bidder an unfair advantage in competition. Front-end loading alone usually fails the materiality test on a project with a performance bond and retainage. It becomes material when the loading is extreme enough that award to that bidder costs the owner more in the end.

The $1.00 per cubic yard rock item is the more interesting number. A very low unit price on an item whose quantity may grow is not a cost risk to the district - if rock quantities increase, the district pays less per yard. The risk is a different one: a bidder who has priced rock at a dollar has no incentive to classify material as rock and will instead argue that the material is unclassified, that it is a differing site condition, or that the excavation is outside the item, and file a claim. That is a claims risk dressed as a bargain, and it should be flagged in the pre-award meeting.

Recommendation: do not reject on front-end loading alone. Require a written unit-price breakdown and a statement of the basis for the $1.00 rock item, verify the bond and the retainage provisions, and put the district on notice that any claim to reclassify rock will be measured against the bidder's own unit price.

3. What would you recommend to the district's board, and how would you handle the bid bond if the bidder refuses to honor the corrected bid?

Read the worked answer

Recommendation: award to the second low bidder at $8,690,000, provided the low bidder's withdrawal is confirmed in writing.

Reasoning, in numbers the board can follow:

  • The corrected low bid is $8,880,000; the second bid is $8,690,000, which is 98.2 percent of the $8,850,000 engineer's estimate - a competitive, credible number.
  • The gap between the corrected low bid and the second bid is $190,000.
  • Rebidding costs about $60,000 in staff time plus six weeks, and delays occupancy three months; the carrying cost of that delay to the district exceeds $190,000 by a wide margin on any reasonable assumption.
  • Awarding at the uncorrected $8,412,000 is not available under the bid form and would invite litigation.

So there is no scenario in which rebidding is the better decision, and no scenario in which the district should accept the erroneous number.

The bid bond. The bond secures the obligation to execute the contract at the bid price. If the bidder refuses to sign at the corrected price, forfeiture is legally available - but it is not automatic, because a bidder who can show a bona fide clerical error with clear and convincing evidence may be excused. Practically:

  1. Request the bidder's original takeoff worksheets and the steel subcontractor's quote to verify the intended unit price.
  2. If the error is honest and clerical, accept the withdrawal in writing and release the bond. Pursuing a bond claim for a $190,000 spread will consume legal fees, delay the award past the board's schedule, and generate exactly the procurement dispute the district does not need.
  3. If the worksheets suggest the "error" was a business judgment discovered after the bid opened, contest the withdrawal and pursue the bond.

Document the analysis in a board memo so the decision is defensible and the reasoning is on the record before anyone is unhappy.
