The proposed development of Warisan Merdeka is expected to cost RM5 billion.
It would be implemented in three phases over 10 years.
The project starts with the 118-storey tower which will be located at Taman Merdeka Negara. It is scheduled to be completed in 2015.
The development site is located near Stadium Negara and Stadium Merdeka.
Prime Minister Datuk Seri Najib Razak had announced the project in his 2010 Budget speech.
