Design of the two 40+ storey towers and 140,000m² extension commenced in the mid 90s but was delayed by the Asian financial crisis. Beca continued its involvement with the project and helped see it through to completion in 2009.
Plaza Indonesia is one of Jakarta's most prestigious developments. The existing complex includes the Grand Hyatt Hotel and the prime Plaza Indonesia Shopping Centre. The extension project, which commenced in 1994, includes two 40+ storey towers on a 7 level podium and has 140,000m² of office and residential space, plus five levels of underground car parking. Delayed by the Asian financial crisis in 1998 it recommenced in 2003 and was completed in 2009.
Beca provided mechanical, electrical, plumbing and fire protection engineering, including designs for standby power generation, water and wastewater treatment, communications and vertical transportation for the four new project components.
- A 7 level extension of the existing retail plaza, with exclusive shops located around two new atria. Beca designed specialist smoke control features to aid egress in a fire emergency with the final design incorporating automatic fire shutters to limit the size of each fire zone
- A 5 level parking basement incorporating an excavation depth saving ductless plenum ventilation system
- The 42-level 'The Plaza' office tower which has a central air-conditioning system with energy-efficient VAV systems and air handling plant on each floor. These are cooled from a primary/secondary chilled water reticulation which includes pressure break heat exchangers and outdoor air pre-cooling
- The residential tower, known as the "Keraton", (Palace), rises 48 levels above ground and has apartments that range in size from 250m² to 500m². The mechanical and electrical systems feature sophisticated designs and incorporate individual VRV air conditioning; a novel "backbone" drainage system allowing the flexibility for the location of wet areas; electronic security systems and a central communications systems including cable TV.
Beca worked with PT PIR, their international architects and structural engineers and local M&E engineers PT Hantaran Prima Mandiri, to deliver cost effective and coordinated mechanical and electrical designs.
