[4] Before the administration of President Rodrigo Duterte, the Philippine Olympic Committee had previous plans to put up a national training center outside Metro Manila but talks to establish such facility did not have any significant progress.

[5] There was also an earlier plan in the 2000s to build a sports complex called the Philippine Olympic City in the Clark area, which was intended to be used as a venue for the 2005 Southeast Asian Games.

A ₱1 billion savings from the PSC could be used to partly finance the construction by the BCDA, a GOCC that developed the Clark and Subic as well as Villamor Air Base and Fort Bonifacio.

[5] Groundbreaking for the National Government Administrative Center (NGAC) as a whole was held on January 23, 2018[8] and actual construction started on March 15, 2018.

[9] The New Clark City Sports Hub forms a significant portion of the Phase 1A of the larger mixed-used government complex's development.

[17] BCDA president Vince Dizon stated that the sports complex will privatize its maintenance and operations right after the SEA Games.

[23] They also planned to turn the complex into a multi-purpose, similar to what London and Sydney did after their hosting of Summer Olympic Games respectively.

[25] Most structures within the complex has a dark gray lahar finish as nod to the nearby Mount Pinatubo, a volcano.

[27] The main stadium, which had its design was derived from Mount Pinatubo, had its posts and facade made from lahar or volcanic debris from the volcano.

[26] The Aquatic Center's design consist of a huge open shed with a prismatic roof similar to a parol made of capiz coating.
