A Cranston builder is avoiding prison following a federal conviction for filing false claims and false documents.  Prosecutors say Donald Ihlefeld [[ ILL-uh-feld ]] owned the Alhambra Building Company in Warwick when the crimes took place.  Ihlefeld admits that he filed false claims in order to collect close to two-million-dollars in federal funds during the renovation of a former West Warwick textile mill.  His sentence calls for two years probation and 200 hours of community service.
