Menara BCA
Menara BCA is a 56 stories Premium Office Building of e u O ce u d g o100.000 m2 Gross Floor Area. It is integrated with Grand Indonesia Shopping Town. Leased to the Multi National Company (Mining OilCompany (Mining, Oil, International Flight, Securitas, Environment Agency) and g y)largest National Bank.
