make contact with (someone or something)
1. To communicate with someone. Has anyone made contact with Grandma since the storm hit?
2. To touch someone or something. Be careful not to make contact with that plant—it's poison ivy. We have a massive leak because the construction crew made contact with a pipe while drilling in our basement.
3. To engage with an unknown entity for the first time. Do you think we'll ever make contact with intelligent life? The government strictly forbids anyone from making contact with the indigenous tribe.
