An update has been given to the Bethel Public Site and Building Commission about progress on renovations at Rockwell Elementary School.  At their meeting Tuesday, the group got a report from Rizzo Corporation that 12 portables were arriving Wednesday.  Installation is set to begin next week.   Demolition of the boiler room at Rockwell Elementary School in Bethel started this week.  This is part of overall renovation work.  Two weekends of abatement were successfully completed and testing reports to the state have been completed.  Work continues on renovations at Johnson School in Bethel.  Gymnasium demolition will start once furniture has been removed.  The abatement of floor tile and stair replacement can then start.
