Methods of assembly of prefabricated truss construction modules

A method, comprising:

• providing or assembling a rectangular horizontal member;
• joining a vertical member to the rectangular horizontal member such that the vertical member bisects a length of the horizontal member and forms a T-junction at the horizontal member;
• joining first and second sloped members to the rectangular horizontal member and vertical member such that the first and second sloped members span from a top of the vertical member to opposing ends of the horizontal member, each first and second sloped member having a groove cut into an underside portion;
• and
• joining first and second support members such that the first and second support members span from first ends disposed on either side of the T-junction between the vertical member and horizontal member to opposing second ends which only make direct contact with work points on the underside portion of each of the first and second sloped members at each groove, wherein the second ends of the first and second support members are precision cut male ends which are mated with each groove;
• wherein no additional support members are joined such that each of the first and second sloped members has no more than one work point disposed on their respective underside portions between the top of the vertical member and each opposing end of the horizontal member.
