The years of economic contraction in the 1990s slowed this sector as it did others; the shell of the 105-story Ryugyŏng Hotel towered unfinished on Pyongyang's skyline for over a decade. The Bank of Korea claims that construction's share of GDP fell by almost one-third between 1992 and 1994, from 9.1% to 6.3%. This accords with a rare official figure of 6% for 1993, when the sector was said to have employed 4.2% of the labour force. However, the latter figure excludes the Korean People's Army, which visibly does much of the country's construction work.
