Engineer Edward "Ed" Butera spent hours constructing models from the time he was a five-year-old boy in San Jose, California. Besides his interest in building and design, the young Butera also loved math and music—specifically the clarinet, at which he excelled, and which he still enjoys. After earning his Bachelor’s degree in Electrical Engineering at San Jose State University he was hired by Ralph Joeckel as a consulting engineer for Trane, a heating and air conditioning company. Joeckel became a mentor and "second dad" to Butera after the company sent him to Las Vegas in 1972, and the two remain close to this day. In this interview, Butera shares how he engineered and designed power, water, sanitation, utilities, and heating and cooling systems on many Clark County high schools, hospitals, and data centers while considering such factors as the building's shape and its affect on the way wind forces act on its glass, windows, and doors. He talks of his casino work that began with the Stardust soon after he arrived in Las Vegas, and before his client list grew to include Tony Marnell, Steve Wynn, and MGM. Besides the hotels, he shares his experiences engineering the infrastructure for the Bellagio fountains, The Mirage volcano, Treasure Island's pirate show.
