note: I'm not 100% sure of the following translation ; it's based on the description of "first fix" and "second fix" found on this page : http://www.buildstore.co.uk/materials/carpentry.html

first fix : travaux de gros oeuvre
second fix : travaux de finition

other possible translation :
"charpentier pour les travaux de gros oeuvre"
"charpentier pour les travaux de finition"
