(concurring):
I join in the court’s opinion because I understand it to lay down and apply the same standard as has been used by the Boards of Contract Appeals in cases such as Ivey Bros. Construction Co., Inc., Eng. BCA No. 1764 (1960) (unreported deci*1363sion); Gust K. Newberg Construction Co., Eng. BCA No. 2754, 67-2 BCA ¶ 6490, at 30.116-18; I. K. Construction Enterprises, Inc., ASBCA No. 10987, 67-1 BCA ¶ 6271, at 29,027; Eastridge Excavating Contractors, Inc., Eng. BCA No. 2683, 67-1 BCA ¶ 6379, at 29,534-35; A. L. Harding, Inc., DCAB No. PR-44, 65-2 BCA ¶ 5261, at 24,777, aff’d on reconsideration, 66-1 BCA ¶ 5463, at 25,590-91, and Power City Construction & Equipment, Inc., IBCA No. 490-4-65, 68-2 BCA ¶ 7126, at 33,024-26. That rule permits an equitable adjustment to cover increased costs which were the direct and necessary result of the change or changed conditions, where the condition or the change directly leads to disruption, extra work, or new procedures. The record makes it very clear that such is the situation here and that the Engineers Board could not properly find the plaintiff’s added costs to be merely “consequential”.
