The value of merger and acquisition deals among global engineering and construction firms rose to $13.03 billion in the third quarter of 2010, says financial services firm PricewaterhouseCoopers, New York City. The figure was up from $11.43 billion in the previous quarter, even though the number of transactions tracked dropped to 35 from 43. But the firm claims the value of “megadeals”—those worth at least $1 billion—more than doubled in the quarter, to $7.2 billion from $3.55 billion . Kent Goetjen, the firm’s E&C sector leader, credits the megadeal increase partly to “reduced capital constraints and low activity in 2009.”
