INNSBRUCK, Austria (AP) ― The head of the organizing committee for the 2014 Sochi Winter Olympics has “no doubts” that all construction work will be finished on time despite delays at more than 70 projects.

“It has nothing to do with a real delay that could harm the games,” Dmitry Chernyshenko said Monday while visiting the Winter Youth Olympics. “We are well on track ― 87 percent of the infrastructure has been done already.”

Chernyshenko said slowed construction works in the region would not affect the games because less than 15 percent of all building projects are directly related to the event.

“The majority of the work has nothing to do with the success of the games,” he said. “All the competition and noncompetition venues for the games are well on track. No doubts that we deliver that.”

Russian Deputy Prime Minister Dmitry Kozak acknowledged the delays Sunday but denied the Olympics would be affected.
