Bethel officials are discussing how to proceed with the police station construction company to fix some problems and finish a few remaining tasks.  The Public Site and Building Committee on Tuesday discussed a leak in the firing range, likely caused by water trapped in the panels of a wall, cracked trim boards and a drainage problem near the radio tower.  Hearst Connecticut Media reports that Downes Construction hasn't been paid in three months, which committee members hoped would have spurred corrective action.  A critical railing for a retaining wall has not been installed yet, but is needed before a full certificate of occupancy can be issued.  The $14.4 million building opened in October.  The project came in about $890,000 over budget.
