Allegations that illegal immigrants were working on the $63 million courthouse project came to light last week when a bricklayers union organizer questioned the county.

Another bricklayers representative said he talked with employees at the courthouse in November and asked if papers were needed to get a job there. The employees said no papers were needed and that they were paid in cash, said Jose Alvarez, business marketing representative of the International Union of Bricklayers and Allied Craftworkers in Washington.
