Rick, you say delays caused by external forces, Lingle not signing off on the EIS for over a year.    Lingle received the EIS  in June of 2010 which was quickly signed by Abercrombie in Dec. 2010.  Lingle did not want to sign for because of concerns about the project’s financial foundation, and basically she was right about it.  Paulette Kelekini, sued because the city didn't follow State law regarding the AIS for projects.  And the lawsuits by Cayetano, Work on rail was never stopped by a court order on any of the lawsuits brought on by Cayetano and company.  What about the delays caused by the city.  Issuing contracts in 2009  yet never got the ok to start construction by the FTA until 2012.  You need to stop blaming others and start putting blame where it belongs.  All delays were fault and caused by the city.  If the city had not rushed this project, and done everything by the book, none of this would have happened.

Ex Output:
No
