Simulation of smoke spread within the station space for various fire scenarios to determine tenability requirements for a performance based determination of egress times and hence the adequacy of the exit provisions for the station.

Changi Airport - Terminal 1 Upgrade

Developed performance based smoke control design for large open spaces in the expansion of Terminal 1. Existing terminal had no smoke control provisions.  The fire engineered smoke control alternative permitted the use of open spaces and significantly reduced the prescriptive smoke extraction requirements whilst assuring the fire and life safety levels for the airport are not compromised.

Asia Centre - City Room Podium

The City Room is a large W-shaped atrium (joining of a series of voids) measuring approximately 180m x 90m x 20m, wrapping around a pair of 40 storey office towers.  The voids which form the W-shaped atrium rises up to about 18-21m high, the height of the truss being about 3m deep, i.e. from 18m to 21m.  The smoke management for the City Room has been designed to be naturally ventilated.  The internal space was modelled to ensure that the provision of natural ventilation louvers and skylights in the roof (allowing partial natural solar lighting), coupled with the natural airflow from the external wind was sufficient to not result in dead or 'hot' spots within the space.

Changi Airport - West Outdoor Deck

Assessed the thermal comfort of an outdoor deck, where a large portion of the area was shielded from the sun using canopies. The impact of the wind and the surrounding buildings were accounted for, including the prevailing directions of the wind. Fans were also simulated to assist with improvements to thermal comfort.

One City - Phase 2 Podium, Kuala Lumpur

The Phase 2 podium comprises an internal space resembling a partially enclosed atrium within a 12 storey mixed-use development measuring approximately 100m × 250m × 76m (WLH).   The podium is naturally ventilated and is connected to the outside via vertical gaps on the side and end walls.  The internal space was simulated to determine the minimum dimensions of the gaps that will provide sufficient ventilation to achieve acceptable levels of thermal comfort for the users of the podium.

Tradewinds, Kuala Lumpur

Mixed development comprising of retail, office, hotel, serviced apartments and medical center. It also has a 6 level basement carpark. The development is divided into 4 towers built above a podium. A performance based assessment of radiant heat flux by point source method and Computational Fluid Dynamics modelling was conducted for the Tradewinds Tower to demonstrate and verify the adequacy of the proposed separation distance in achieving the performance objectives for fire safety compliance.

Tuas West Depot Stations

The curved roof which shielded the station allowed hot air to be trapped. The requirements for additional roof vents were studied over and above the wall louvers to provide adequate thermal comfort to the passengers utilizing the elevated dual platform station.

Rolls-Royce - Red Dot Facility

The Red Dot Facility is an Industrial Development comprising a single storey assembly building with ancillary facilities and a 3-storey research/development/administration building with canteen.   The proposed facility measures approximately 140m × 112m.   The roof is curved (on one plane only) along the longer dimension such that the eave height begins at 16m and rises up to 22.7m at the centre.   A preliminary study was undertaken to demonstrate viability of a proposed smoke management strategy to minimize the number of make-up air points and extraction fans with only a single run of ductwork.

Paradigm, Kelana Jaya - Basement Level Carpark, Kuala Lumpur

The underground carpark levels comprise of Basement 1 to 2, each measuring 37,000 m² of uncompartmented floor area and volume of 159,100m³, which exceeded the size limits for compartmentation.   An engineered smoke control system using virtual zones was designed, complementing the preferred ventilation shaft layout, and demonstrated that the smoke and heat could be successfully contained without requiring fire or smoke compartmentation.
