September, 2007: Construction continues to progress at the World Trade Center (WTC) site. Developer Silverstein Properties has made steady progress on the Freedom Tower and the installation of steel columns continues as the concrete slab is being poured to form the tower's base. Additionally at the site, Port Authority has been preparing the "east bathtub," which includes excavating, building the permanent slurry walls, and relocating utilities. Foundation work for the National September 11 Memorial & Museum began in March 2006 and is now nearing completion. The first phase of structural framework installation is now underway.
