#22 Masonry Construction Technique

Description:  Why is the front of that building covered in a tent of plastic?  This construction technique is used to raise the temperature of the work space within the plastic and to block the wind.  Inside that scaffolding and plastic encasement the temperature is much warmer than the single digit temperatures experienced outside.  This warmer space allows for the construction of masonry finishes which would be nearly impossible in the freezing temperatures of winter.
