Tech Auto (Plaintiff) purchased concrete from Morris Concrete (Defendant) as a foundation slab for a metal building it intended to use as a tire service shop. When Plaintiff ordered the concrete, he specified that it needed to be capable of withstanding 3,000 pounds of pressure per square inch (“PSI”), which was required for the automobile lifts Plaintiff was going to have installed. Plaintiff paid Defendant the agreed price of $30,000 for the concrete and installation. Purchase and installation of the lifts was necessary to enable Plaintiff to operate a tire shop.   After being informed by a representative of the automobile-lift company that there might be a problem with the quality of the concrete, Plaintiff contacted Defendant. Defendant subsequently employed an engineering company to test the concrete. The testing results indicated that the concrete’s tolerance was well below 3,000 PSI. It was therefore useless to Plaintiff and would have to be removed and replaced with proper concrete strong enough to support the automobile lifts. The estimated removal costs of the existing concrete was $15,000, and Plaintiff would be required to pay $25,000–$30,000 for the replacement concrete. Plaintiff testified that it would take approximately 1.5 years to remove the concrete, re-excavate the area and pour the proper concrete so it could go forward with its business plan.   Plaintiff sued Defendant seeking damages for breach of contract. The complaint sought damages for the cost of the concrete; its removal and replacement; and loss of profits which Plaintiff expected to receive through expansion of its business to include the sale of new tires. Defendant filed its answer with the appropriate affirmative defense to challenge Plaintiff’s lost profits claimed, and the case proceeded to trial.   Plaintiff, by testimony of its owner at trial, stated that it wanted to expand its business by selling and installing new tires which it had never done. Plaintiff testified that the nearest tire stores were about 20 miles from its location; it expected to sell at least two sets of tires per day and expected to generate about $40,000 in additional gross income per year.   On cross-examination, Plaintiff admitted it had no prior experience selling new tires; had not contracted with any tire company; and could not testify to the exact profit margin expected on tire sales and had not purchased the automobile lifts. No expert was called by either side.   Plaintiff sought a total judgment against Defendant in the amount of $105,000. It was based upon the $30,000 it had paid Defendant for the original concrete and installation; $15,000 for its removal; and lost profits in the amount of $60,000 based on Plaintiff’s estimate of lost profits for 1.5 years. Defendant admitted its breach but objected to the proffered testimony on the grounds that Plaintiff’s claim for lost profits was not supported by any competent evidence and should be rejected by the trial court.   Please identify and discuss the affirmative defense raised by Defendant and the applicable law in view of the facts and testimony provided and your opinion what damages, if any, Plaintiff is entitled to claim and receive at trial.
