If I do not hear from the construction employer after my interview, should I contact him or her directly to inquire?

Is it appropriate to contact the construction employer after a week or so if you haven't heard anything, especially if you believe you were a good fit for the position. Hopefully you have already sent a "thank you" letter or email to all of the people you interviewed with. The best person to reach out to would be the hiring authority (boss) who you would be reporting directly to.
