SNC-LAVALIN AMERICA, INC., Plaintiff/Counter-Defendant, v. ALLIANT TECHSYSTEMS, INC., Defendant/Counter-Plaintiff. Civil Action No. 7:10CV00540
SNC-Lavalin America, Inc. ("SNC") filed this diversity action against Alliant Techsystems, Inc. ("ATK"), asserting claims of breach of contract, unjust enrichment, and promissory estoppel. The action stems from the design and construction of a new nitric acid and sulfuric acid concentration plant ("NAC/SAC") [*2] at the Radford, Virginia arsenal owned by the United States Army and operated by ATK. SNC and ATK entered into a written contract pursuant to which SNC agreed to provide engineering, procurement, and construction services. The primary source of the instant dispute is SNC's demand for payment for additional costs that the company allegedly incurred as a result of (1) an ATK-directed change to the type of floor coating used on the first floor of the NAC/SAC; and (2) ATK's denial of a requested extension of the contract time due to severe winter weather. The case is presently before the court on ATK's motion for partial summary judgment. The court held a hearing on the motion on October 4, 2011.
