The second phase, however, could add $1 billion to the price and require closing the convention center for several years.

Later that year a second phase added another classroom and a boiler room.

The third phase of the plant was under study in 2007 and adds an extra 80,000 m3 capacity.

The second phase of construction will add another 84 apartments.

Further phases of development may yet add to the exhibition space.

The third phase, at about $180,000, would add the top floor and terrace.

A second phase, scheduled for construction next year, will add 150 to 200 more.

This phase could add about another 1,000 and would be based upon demand.

The second phase added a 100-seat cafeteria and 90-seat conference center.
