Introduction

We are going to break down the framing into 11 framing modules that will be assembled on the ground in parallel with other construction processes.

This is the how-to for the modules of the 2nd floor. Starting from the south, they are labeled 4-9 with an "a" and "b" distinction referencing their location on either west or east respectively.

  1. Gather materials for mod 9a&b (these are enough materials for BOTH walls)
    • Gather materials for mod 9a&b (these are enough materials for BOTH walls)

    • 8:2x4x8

    • 2:2x4x10

    • 2 sheets of 3/4"x4'x8' OSB for exterior sheathing

    • 2 sheets of 1/2"x4'x8' plywood for interior sheathing

    • ~buncha 3-1/8" construction screws

    • ~buncha 1-5/8" coated deck screws

  2. Cut Framing Members
    • Cut Framing Members

    • 4: 2"x4"x5'5/8" (verticals)

    • 2: 2"x4"x4'3/4" (horizontal top/bottom)

    • 3: 2"x4"x2'9" (window frame top/bottom)

    • 2: 2"x4"x3' (window frame sides)

    • 1: 2"x4"x1'7-5/8" (blocking over window)

    • 1: 2'8"x3.5"x1/2" plywood

  3. Assemble Framing
    • Assemble Framing

    • Place vertical studs (60-5/8") inside horizontal top and bottom plates (48-3/4")

    • Sandwich plywood strip between two of the three 33" pieces and screw together (three screws across length is fine)

    • Use sandwich to form top of window box, use 3' members to form sides and remaining 2'9" member for the base; screw together with 3-1/8" screws (toe-in screws at a diagonal into top plate from side members)

    • Screw one stud (60-5/8") to either side of window box; letting top of studs hang free off the top of the window box but making sure they are all aligned at the bottom

    • Toe-in center vertical above window box

    • Place top and bottom plate such that vertical studs at edges leave a gap of 7" to one side of window, and 2-3/4" on the other.

  4. Cut and attach Exterior Sheathing (OSB)
    • Cut and attach Exterior Sheathing (OSB)

    • 1: 34-1/2"x24-5/8"x3/4" OSB

    • 1: 34-1/2"x7-3/4"x3/4" OSB

    • 1: 71-1/8"x10"x3/4" OSB
