The Honolulu City Council voted Wednesday to approve two permits allowing construction to restart on the $5.26 billion rail project, after more than a year of delays.  Construction crews will be back in the fields of East Kapolei erecting concrete columns for the project on Monday. Dan Grabauskas, executive director of the Hono­lulu Authority for Rapid Transportation (HART), said work will restart in a couple of places simultaneously -- on the columns and also regrading will take place at the maintenance and storage facility in Waipahu.
