Our building engineering professionals provided innovative and sustainable solutions for one of Singapore’s most energy efficient commercial developments.

AECOM provided engineering and consultancy services for Asia Square, a twin-tower mixed-use development with a total gross floor area of approximately 246,700 square meters.

Situated in the new Marina Bay business and financial centre, the high-rise towers comprise a 43-storey and a 46-storey building which include offices, retail and food and beverage space. A five-star hotel, The Westin Singapore Marina Bay, is also located there.
