HOUSTON — International engineering firm Walter P Moore announces several key changes within the firm's structures group, which encompasses structural engineering, enclosure engineering, construction engineering, secure design, and parking consulting.

Blair Hanuschak, P.E., senior principal, has been promoted to executive director of structures, which spans 19 U.S. offices, five international locations, and comprises roughly 54 percent of the firm's employees. Hanuschak will captain an executive suite of structural leaders, which includes senior principals Mark Larsen, P.E., S.E. (operations director); Viral Patel, P.E. (director of design); and Mashari Nassar, P.E. (client director).

A 27-year veteran at Walter P Moore and member of the board of directors, Hanuschak has served as a regional and managing director for structures and as global aviation practice leader. He has been instrumental in establishing the firm as a leader in airport design. In 2008, he founded Walter P Moore's Washington, D.C., office, now the firm's second largest U.S. location. He will continue to be located in the Washington, D.C., office.

"Blair is a proven leader, and I am confident that his charismatic and collaborative style, vast experience, and client savvy will make him a very effective Executive Director," said Dilip Choudhuri, P.E., CEO, in making the announcement.

Blair succeeds Lee Slade, P.E., senior principal, who has led the Structures Group since 2001. Slade continues to serve the firm as the chairman of the board and will be transitioning to a new role that leverages his engineering passion and 42 years of experience. Throughout his prolific career, Lee has served as a visionary leader, both for the structures group and for the firm as a whole. Under his direction, structures grew by $30 million in revenue, added three new practice areas, opened eight offices, and added 60 new principals (including 12 senior principals).
