An inspection committee from the Commonwealth Games Federation (CGF) have warned Glasgow 2014 against complacency despite giving a favourable review to their preparations following their penultimate scouting mission to the city.

CGF vice-president Bruce Robertson has confirmed plans to bring athletics' Diamond League to Hampden in July ahead of the Games, with the National Stadium also set to stage the Scottish Schools Championships to prove an initial dry run for the purpose-built track which is soon to be laid over the existing football pitch.

Transportation and the command and control of security operations have been identified as the two main challenges still to be finalised while it has been revealed that the organisers have secured 13 additional sponsors for the event.

However, Robertson remains bullish that Glasgow can confront the remaining hurdles head on and stage the Games without a major hitch.

"It's going to be a very hectic seven months from January through to July," the Canadian said. "But based on our previous Games experience, and where we see the organising committee sitting at this minute in time, we're comfortable.

"There's no complacency, you can't take anything for granted. But there is time to complete all the work that needs to be done. The Games will be staged in July. From the plans we've seen across the board, we think it's going to be a spectacular experience."

It is a vote of confidence for Glasgow 2014 chief executive David Grevemberg, who has denied suggestions that Strathclyde Park, near Motherwell, might be ditched as the venue for the triathlon competitions due to poor water quality in the venue.

Proposals to insert barriers in order to create a clean space in the lake were drawn up after the swimming leg of a previous British Championship event had to be scrapped because of pollution caused by algae. And even though Loch Lomond officials have made public their interest in stepping in to fill any void, Grevemberg insists there will be no late change of plans.

"We haven't announced any contingencies," he said. "I know there's been expressions of interest from other locations in Scotland saying: 'if it doesn't work, we're here.' We're focused on making sure that site, as planned in the bid, is fit for purpose."

An option to switch the final of the netball competition from the SECC to the Hydro Arena will be retained, it has been confirmed, but no decision will taken until a logistical test at the newly-opened venue takes place in the New Year.
