Singapore Telecommunications (Singtel) has announced plans to build a SG$400 million ($282.63 million) Tier 3-Plus data center, in what it's touting to be its "biggest" investment in the country.

Located in the southwest area of Jurong, the new facility will span a gross floor area of 570,000 square feet and is expected to be completed in third-quarter 2016, said Singtel in a statement on Thursday.
