The completion year is not settled. Pelli Clarke & Partners' project page gives 2014, while Wikipedia's[2] infobox and text give 2013, with finishing work running into 2014 and the official opening postponed to that year. The architect's 2014 is kept, dated to the last day of the year, but only as an estimate.
