Construction is under way for a Games 'centerpiece' in the heart of the city centre.

Builders are currently putting together a representation of the Games logo in George Square as seen in this picture taken by our staff photographer Colin Templeton.

‘The Big G’ -  that's the affectionate name that has already been given to the spectacular new installation which is to be officially unveiled in Glasgow's George Square on Friday.

The gigantic, three-dimensional structure, which has been designed to reflect the Games logo and is taller than a double decker bus, measures a whopping 5.5m (18-feet) in height by 10.2m (33.5-feet) in circumference. At four tonnes, it also weighs the equivalent of an African elephant.

It will provide a stunning backdrop for Glasgow’s celebrations when the Commonwealth Games begin on July 23 and will serve as an iconic welcome to the city for visitors, spectators and a global TV audience of some 1.5 billion viewers.

The launch of The Big G will be carried out by 10 Glasgow school pupils from Anderston; St Timothy’s; Annette; Blairdardie and Sandaig primary schools. They will be joined by the Leader of Glasgow City Council, Councillor Gordon Matheson and Glasgow 2014 chief executive, David Grevemberg.

The official logo for the 2014 Commonwealth Games was unveiled on Commonwealth Day on March 8, 2010. It was designed by Marque Creative, and it was inspired by three factors, time, data and measurement. Its rings are proportioned to represent the 20th Commonwealth Games, across 17 sports, over 11 days in one city

The official Olympics rings logo was previously housed in the city centre landmark during London 2012.

People sharing their images of The Big G on social media networks are encouraged to use the hashtag, #TheBigG.
