[2] The IC3 Convention Center was built as the IEC Pavilion, meant as the primary venue of the 2016 International Eucharistic Congress.
[15] Among the people involved in the construction of the project is architect Carlos Pio Zafra and project-in-charge Engineer Adonis Gabutin.
Camangyan noted that Cebu Auxiliary Bishop Dennis Villarojo called for "low maintenance building" specifying that there would be no finishes to be done on the floor so that it can be cleaned using a mop.

The grand hallway of the convention center is dubbed as the Ganghaan Walk where photos of the 2016 International Eucharistic Congress are exhibited.
