This paragraph explains the method we will use to properly install and tighten the connection bolts on the project. Though there are several different methods, the one most commonly speci- fied in the pre-engineered steel building industry is the "Turn of the Nut" method. Stran Building Company has specifically requested that this method be utilized on their structures. Because this is the method most often used, and Grenier Construction Co. has been erecting metal buildings for over twenty-five years, I assure you that our personnel are very fami- liar with this and all proper erecting procedures. If you, or any of the parties concerned with this project, have further questions, I will gladly answer them. Very truly yours, Joseph R.
