Conditions & Fundamentals of Hajj and Umrah

Back or chest facing the Ka'bah during tawaaf due to construction barriers

Q: During tawaf on the first floor there are times where construction barriers are blocking off certain areas. It is such that we have to walk diagonally where our shoulder moves away from the Kaabah and it seems like our back is facing the Kaabah (but we can't be certain because we can't see the Kaabah from the first floor). It happens few times during tawaaf. What should we do in this situation?
