The $US15 million building will provide teaching and learning spaces for all disciplines currently offered in Vietnam and forms Stage.
Three of RMIT's development in Ho Chi Minh City. It will also house specialised learning spaces for digital design/media and communications, and support spaces for staff and administration.
RMIT Vice-Chancellor and President, Professor Margaret Gardner AO, welcomed the expansion.
"The growth of RMIT Vietnam means more students – whether from Vietnam, Australia or worldwide – can enjoy a quality education in Ho Chi Minh City.
"The close linkages between RMIT's campuses in Melbourne and Vietnam and our Study Abroad programs provide students with the chance to study and work in a different cultural environment.
"Our emphasis on work integrated learning also means that students in both countries can make a meaningful contribution to the community through collaborative projects."
Meanwhile, Stage Two of the Saigon South campus building project is expected to finish in March.
RMIT Vietnam President, Professor Merilyn Liddell, said the new sports facilities and accommodation would allow students to enjoy a rounded university experience, combining education, sports, leisure and social interaction.
A sports and leisure centre will include a sports field for soccer, rugby union, Australian Rules football, cricket, softball, baseball, and ultimate frisbee, as well as tennis courts, an indoor centre featuring a multi-sport court for basketball, badminton, volleyball and table tennis, and a gymnasium.
There will also be meeting rooms, and rooms for aerobics, dancing yoga, and martial arts instruction, a café, a health clinic, indoor seating for 1,500 spectators, and grandstand seating for 800 overlooking the sports field.
Professor Liddell said the residential centre would provide international-standard accommodation with energy and water-saving features and finishes in keeping with the environmental management principles adopted by RMIT Vietnam.
Cable television and high-speed internet connections will be available. A café and retail facilities are included in the complex.
RMIT Vietnam has campuses in Ho Chi Minh City and Hanoi. It began in 2001 and now has a student population of more than 5,000.
