A DINING hall for 2000 athletes, a small hospital and "chill-out" areas where sportsmen and women from around the globe can relax are among the buildings being put together as the clock ticks down to the start of the Commonwealth Games.

With just 100 days to go, a complex programme of works is under way to make sure Glasgow is ready to host its biggest festival of sport in decades.

The Commonwealth Games will attract 4500 athletes from more than 70 countries to compete in more than 250 events across 17 sports.

Organisers say they have no concerns about getting ready, but are having to work to a tight timescale prepare venues and ensure each nation's team has access to all the resources it needs.

Ian McKenzie, Glasgow 2014 head of venue and village development and integration, said a concerted effort was being made to get the city ready and a tight schedule is in place.

He said: "Things are proceeding on track. Some areas are going better than others but we're in fine shape. There's nothing causing us concern and we're going to get there.

"The capital development venues are all completed and we are hard at work at Hampden installing a running track and areas for medal ceremonies and coaching staff."

The specialist running track is being laid at Scotland's national stadium using around 6000 steel stilts to raise the surface by about 6ft (2m).

The £14m project is being carried out to create a surface which will meet International Association of Athletics Federations-approved track standards.

As well as transforming Hampden Park from a football stadium to an athletics venue, preparations are also being made to ensure competitors feel at home in the athletes' village when in opens on July 13.

Any medical problems suffered by athletes will be treated at a small field hospital, complete with doctors' surgery and dentist rooms, while the biggest single building yet to take shape is a dining hall capable of seating 2000 people.

Due to be completed next month, giving time for caterers to install the kitchens which will be used to feed hundreds of competitors each day, the building's roof is being assembled even as its supporting walls go up, allowing it to be fitted together next month.

The race to the finish line will also see construction of three recreation areas for competitors, fewer than is usual for games of this size.

Mr McKenzie said: "We wanted to have areas where the athletes can relax away from the cameras. Usually there would be more but ours are bigger than normal to fit in more people.

"Part of the idea behind the village and the recreation centres is that the athletes will mix together and socialise, which has not always been the case at previous Games, to the extent we are aiming for.

"We want to try and ensure the Games in Glasgow live up to the name of the 'friendly games'."

Away from the village and the main stadium, the biggest job will be to install 4500 seats at Glasgow National Hockey centre and "brand" each of the other venues.

Work also has to be completed to install electric cabling and communications equipment for broadcasters, while some nations have also provided checklist of equipment they will need, such as PCs, DVD players and printers.

The 15,000 volunteers who have signed up to take part also have to undergo training, both before their venues open and after they are ready for the Games to take place.

Even then the schedule is not completed - with work to return many areas back to their original state expected to last until October.
