Case Brief Summary & Legal Analysis

General Brief
3 min read

tl;dr: A prime contractor relied on a subcontractor’s low bid to win a construction project. When the subcontractor tried to withdraw its bid post-award, the court used promissory estoppel to hold the subcontractor liable for the price difference, enforcing the original bid.

Legal Significance: This case adopts the modern rule that a subcontractor’s bid becomes an irrevocable offer under promissory estoppel once a general contractor reasonably and detrimentally relies upon it in submitting a prime bid.

Case Facts & Court Holding

Key Facts & Case Background

Defendant-appellant, Bostrom Sheet Metal Works, Inc. (Bostrom), a subcontractor, submitted a telephone bid of $372,000 for ventilation work to plaintiff-respondent, Constructors Supply Co. (Constructors), a prime contractor. The bid was submitted on the morning the prime bids for a university construction project were due. Constructors’ vice president called Bostrom back to confirm the price, and Bostrom’s representative affirmed it. Relying on Bostrom’s figure as the lowest bid for that work, Constructors incorporated it into its prime bid. Constructors was subsequently awarded the prime contract. Several days later, Bostrom notified Constructors that it was withdrawing its bid due to a substantial error and submitted a new, higher bid. Constructors formally accepted the original bid, but Bostrom refused to perform. Constructors hired other firms to complete the ventilation work at a higher cost and sued Bostrom to recover the difference. The trial court found for Constructors, noting that reliance on telephoned bids was a customary practice in the industry.
