Mayor Rodrigo R. Duterte first announced the plan to build the facility in 2013.
Earlier this month, the city council passed on first reading an ordinance authorizing Duterte to sign on behalf of the city a memorandum of understanding with UP on the sports complex.
An in-house team of architects will be designing the facility.
Ungab said the idea of building the complex came about when he was still a city councilor.
“It has always been funding that was the problem,” he said.
