First Baptist Church of Moultrie (First Baptist) (plaintiff) was soliciting bids for a construction project. Each bid had to be accompanied by a bid bond amounting to 5% of the bid. Barber Contracting Company (Barber) (defendant) submitted a bid for $1,860,000 with a 5% bond of $93,000. First Baptist awarded Barber the contract on May 15, 1986. On May 16, 1986, Barber informed First Baptist that Barber had made a mistake in calculating the bid and the cost was actually $143,120 higher. On May 20, 1986, Barber attempted to withdraw the bid. On May 29, 1986, First Baptist mailed Barber a contract based on the original bid price and Barber refused to sign it. First Baptist then accepted the second lowest bidder at a price of $1,919,272 and sued Barber for the $93,000 bid bond. First Baptist and Barber filed motions for summary judgment and the trial court denied both of them, but certified the issue for immediate appeal.
