Here's a short section from a recent contract:
Quote
GC-44 ENGLISH REQUIREMENTS

At all times, all contractor personnel on site must have sufficient knowledge of the English language to comprehend safety related directions and requirements. At all times the contractor shall have a lead representative on site who has sufficient comprehension of the English language to read, write, speak and understand all job related directions and discussions.
I guess the next obvious question is, do we enforce this during performance of the contract? I have no idea.
