James Glass, executive vice president of Shaw Group Inc.’s Energy & Chemicals Group, has been promoted to president of the division.

Lou Pucher, who had held the top slot, will step down and work with Glass until the end of the year to smooth the transition, according to Shaw.

Glass has worked with Shaw or Stone and Webster, which Shaw acquired, since 1970. He has more than 40 years of general management and project execution experience covering the development, project management, engineering, procurement and construction of petrochemical, refinery and energy projects.

In a news release, Gary P. Graphia, Shaw’s executive vice president and chief operating officer, thanked Pucher for his commitment and service.
