With the costs related to an internal embezzlement probe no longer weighing down earnings, Tampa-based PBSJ Corp. reported sharply higher earnings for the fiscal year ended Sept. 30. The company reported net income of $19.1 million on revenue of $581.5 million, compared to $5.4 million in profit on $537 million of revenue in the prior year when costs related to investigating the embezzlement activities of its former chief financial officer and two financial staffers  totaled close to $14 million. As part of a new strategic plan, the engineering firm says it will focus on work in the federal sector, which rose 50% in fiscal 2007 bookings. It obtained new work from the Defense Dept. and the Federal Emergency Management Agency. “Our employees really rallied in the last year and our backlog is strong,” says a spokeswoman.
