Overview of Framing Day
Major tasks of the day
Standing walls
Brace walls
Build and install porches
String walls
Install cap plate
Start sheathing exterior walls
Safety First
Safety glasses required when using power tools
Ramset can only be used by people who are Certified
http://www.ramset.com/patlicensing
Never lean walls against walls that have been stood/placed
When cutting sheathing/OSBBe sure to attach 3 - 2x4 boards on saw horses
The 2x4 boards will allow for a ‘chase’ when ripping OSB
Set saw blade depth to ½” – ¾”
Framing Overview of Build Day
Exterior – Letter + Number
Interior – Number only
Long vs. Short Wall
Nailing Pattern12d nails
Two nails every two feet on both sides
Anchor Bolts
Align wall
Measure for bolt location
Lay wall down
Anchor Bolts cont.
Drill hole with ½” bit
Add/replace Sill Seal
Lift wall onto bolt(s)
Lock in wall
Hilti/Ramset (MUST be Certified)
Walls should align on one line.
Exterior walls – set nail toward the inside edge of bottom plate
Place w/in 6in of each side of the wall
Every 3rd bay or w/in 4ft of anchor bolt
Announce (loudly) “Noise!” prior to activating shot.
Ear plugs are recommended and available
Standing Back Walls
Squaring wallsSet walls next to snap line to measure for slab bolt
Drill bottom plate for slab bolt.
Attach sill seal w/ 2” roofing nails
Stand walls
Plumb walls
Standing walls cont.
2 side wallsPlumb Side Walls and brace
Add 18” plastic sheets to all exterior walls.
Measure 12” from the bottom of plate and snap a line. Let the remaining plastic to hang.
Cover exterior corners with 18” polybarrier.
Standing walls cont. (tips)
Green = BOTTOM
Be sure no gaps between walls
Use cleats to clamp walls together
Be sure bottom plates and top plates are nailed securely to all studs.
Be sure not to stand exterior walls too far ahead of interior wall bracing
Nail off all exterior walls
Plumbing/Bracing walls:
use an 8’ level
Use 2 nails when tacking interior walls
Interior wall corners can be nailed completely off
Never attach blocks on garage floor for bracing
DO NOT remove wall bracing until roof is 80% decked.
Cut Plumbing Walls
Mark plumbing location to be cut.
Prior to cutting:
Move stud(s) if necessary.
Add a horizontal brace with scrap 2x4
Support wall under location of cut(s)
Bathtub
Must be 60”
Wall Issues/Solutions:
Wall is shortVerify wall/bottom plate or top plate is short comparing to floorplan.
DO NOT assume snap lines are correct.
If wall is ½” short, add OSB spacers on either end of wall.
Do not add shims at the corner or end of wall.
Be sure to rip cut OSB less than wall width, typically 3”
Nail to wall using either 8d or 2” roofing nails every foot.
If wall is ¼” short, install wall
Wall issues/solutions: cont.
Wall is long
Verify wall/top plate/bottom plate is long
If wall is ½” long or less
knock stud into place.
If wall is longer than ½”
measure length to cut, remove end component, cut
each plate and replace component then install
wall.
Stringing walls
String all exterior walls
2x4 on outside top corners, run string.
Use straight 2x4 under string to verify
walls are plumb.
After stringing and bracing walls, plumb all
interior walls with 8’ level and nail off.
Cap plate
Measure using bottom plates.
Refer to cap plate plan in Black Binder
Mark measurements on bottom plate and cap plate.
Cap plate only when walls are plumb and strung.
“Walk” cap plate
Overlap at least 4’ from where walls join/intersect.
2 nails over every stud, 5 nails on intersecting walls
Temporary Truss Support
Located in the front of the house where there is a dearth of interior walls.
Use wall pallet to make temporary wall.
Install before last exterior wall is stood.
Adjust to fit space.
DO NOT attach to slab.
Gable End Nailers/Truss Nailers
Located on all walls with gable truss
Placed on top of cap plate
Use non-finger jointed 2x4
‘Walk’ the nailer down the wall
No boards shorter than 4’
1 ½” inches from front edge, at least 1” from ends.
Use a 2x4 as a spacer
Make sure to cover corners

Blocking
With all Blocking
Verify on floorplan where blocking is required
Use non-finger jointed lumber
Use wide side of the block so its flush with interior face of the studs
Attach using 2-12d nails on each side of blocks
“toe nail” when needed.
Be sure at least 1 stud can be used to support shelving bracket(s)
Blocking cont.
ADA/Bathroom BlockingMeasure each location or measure in corners and pop a line at 36” from slab
Can cut 2 2x4 at 31” to support ADA blocking for nailing
Kitchen BlockingEither measure at each location or pop a chalk line at 32”, 55” & 82” from slab.
Can use 2x4 cut at 80½”, 53½” and 30½” to support blocking while nailing
Deadwood
Placed on walls running
parallel to trusses
Use scrap 2x4, non-
finger jointed wood
Use 12d nails every 8-
12”; use at least 3 nails
No more than 3 inches
between pieces.
Cover corners
HVAC Closet
Do not install until after walls are strung and braced.
Prior to sheathing, be sure there are studs for nailers on all corners.
Don’t rest OSB on ground
Do not nail down deck, try to install before trusses go up.
Attic Access
Marking stud locations
Mark cap plate and
polybarrier
Mark over blue board
Used for nail

Sheathing walls:Installed vertically
Start with full sheet from the corner
Insert 3-4 12d nails into sheeting, between slab and bottom plate to hold up OSB
Make sure OSB does not fall below bottom plate
8d nails no more than every 6 inches on perimeter and 12 inches in field
Sheathing gables
All sheathing installed vertically
Measure king post from bottom of the gable to the peak
