Construction has started on the S$350m ($276m) redevelopment of the Comtech commercial building in Singapore.
Mott MacDonald is serving as the project's building services consultant, on behalf of Mapletree Business City (MBC).
The redevelopment of the Comtech building will include the construction of a new 30-storey tower with three stepped podium blocks, providing about 125,000m² of floor area.
The project forms the second and final phase of the MBC integrated business hub, which is designed to revitalise Singapore's Alexandra precinct.
Other components include a business park and retail space, office and meeting facilities, restaurants and cafes and a gymnasium with a heated pool.
MBC will feature one office tower, two business space towers and an amenities/retail block, which will all be connected by covered linkways.
Mott MacDonald said the MBC development, which is located at the fringe of the central business district, is designed to support, enhance and exceed the needs of modern businesses.
Mott MacDonald project director CheeChuan Tan said that the redeveloped complex will be a business park space with high floor plate efficiency.
"The project recently obtained Green Mark Platinum certification, Singapore's highest sustainability award. This was achieved thanks to a predicted 30% energy saving through the use of efficient chiller plants and lighting," Tan said.
Construction is expected to be completed in the first half of 2016.
