"If they are successful in that, it would be a clear indication of the project's feasibility," he added.

The Army Corps of Engineers studied the project's feasibility and environmental impact.

The immediate goal, they said, is to assess the project's feasibility independent of Mr. Diamond's enthusiastic campaign.

If the Engineers Corps approves the project's feasibility, the project will need the approval of the City Planning Commission.

By early 2002 the South Korean Ministry of Construction and Transportation had commissioned three research institutes to study the project's feasibility.

Also in January 1965, the Department of the Interior completed its three-volume, 1,000-page study of the Rampart project's feasibility and impact.

Despite approval of the project's feasibility plans by the National Development and Reform Commission in May 2009, construction has not begun as of March 2011.

"The project's feasibility study is being carried out by Armenia, Russia, the US and the International Atomic Energy Agency.

While the project's feasibility study suggested that three-car units would be preferred, it was thought that the alterations required to Ryde depot would be both difficult and expensive.

Following the release of the report, engineering and planning for the road began, as well as environmental study by the New Jersey Department of Environmental Protection, to determine the project's feasibility.

Mr. Zaslaw's connection to the Lincoln Center celebration began in February 1988, when he took part in a meeting at the Juilliard School to discuss the project's feasibility and desirability.
