A new $238 million arena in downtown Louisville, Ky., is on schedule to open in 2010, officials say. A concrete floor collapsed at the site seven weeks ago, and an investigation determined that a subcontractor incorrectly installed support posts and did not install 22 additional posts. As a result, officials have added more inspectors to oversee concrete pours and created additional procedures to make sure the pours are done correctly.
