Passers by may have noticed the recent addition of a mobile crane to the massive Wilshire Grand construction site.  Perhaps Turner Construction is about to install a larger stationary crane?  Or maybe it has something to do with tomorrow's "bottoming out," ceremony.  Crews have now excavated the site down to 106 feet below street level, capping off a demolition process which began late in 2012.  Soon afterwards, the Wilshire Grand begins a three year climb to its 1,100 foot apex.  When opened in 2017, the tower will contain 900 hotel rooms and 400,000 square feet of office space within 73 stories.  No need to mention the 70th floor lobby and the rooftop pool/observation deck.  Can it please be 2017 already?
