Sinkholes have appeared at the construction site of the Lotte World Tower in Seoul, the Kohn Pedersen Fox-designed skyscraper set to become the tallest structure on the Korean peninsula. At first, the appearance of holes has been reported on two roads close to the site-half a meter wide and 20 centimeters deep. Now it appears the adjacent lake is shrinking.

In addition to the appearance of holes, it has been reported that the lake near the tower has been mysteriously shrinking, with water levels dropping from five to 4.3 meters. A team of engineers, environmentalists and experts have been called in to assess the situation and conditions on the construction site. The presence of underground water that could be coming from the lake was noted by a professor at Kwandong University.

The structure will serve as the new corporate headquarters for the Lotte Group, whose subsidairy, Lotte Construction is in charge of the building process and aims for LEED certification. The skyscraper will include public transport connectors, retail and residential space, offices, a hotel, an observation deck, and other public areas. So far, 123 floors have been built, but the accelerated circulation of underground water could undermine the ground in the area, Professor Park Chang-kun told The Associated Press. The skyscraper is slated for completion in 2016.
