No clear error in holding that general contractor's threatened withholding of payment and interference was the first material breach of agreement with contractor; contractor's continued performance made the termination of the agreement breach, since the fact that the contractor didn't formally challenge a corps of engineers decisions didn't present a per se claim of nonperformance. Damages reasonable.
