The organizer yesterday urged construction workers to maintain the momentum in Expo site construction as time is still "pressing," despite 90 percent of on-site work being finished.

Hong Hao, director of the Bureau of Shanghai World Expo Coordination, noted that site construction has entered the final stage and the task is still "arduous" with only about 100 days to go before the opening.

He made the call during an oath-taking ceremony yesterday at the World Expo 2010 site. The goal is to make the site ready for a trial operation ahead of the Expo opening on May 1.

Hong also expressed appreciation for the hard work of constructors.

More than 700 worker representatives pledged to finish the whole project on time at the ceremony.

About 70 percent of the 42 self-built foreign pavilions have started interior decoration and exhibition arrangement.

The organizer is urging all the participants to finish construction by the end of February and complete outfitting by the end of March.

Another 42 rented pavilions and 11 joint pavilions have been completed.
