    2. Tools for framing: carpenter’s square, speed square, tape measure, chalkline, string line, markers
  1. Blueprint Reading –Distribute old HFH house plans…origin of the term "blueprint" ozalid process- ammonia
    1. Discussion of front/side elevation, floor plan, foundation plan/site plan, electrical plan, truss plan. Questions?
    2. We are not designing anything; our function is to read the plans and execute the building…to build, not redesign but take note for future improvement
    3. Brief discussion of 3 major HFH house plan design models; 3J, 4B, 3G; other models 4F wide and 3HC handicapped
    4. Special to Habitat houses (Louisville): simple, decent; crawl space; a storage area w/outside entry door- access to crawl space; kitchen/dining area usually combined; bedroom layout for each plan; covered entrance; attic storage; trusses for roof
  1. The Floor Plan- shows all you need to know…
    1. Why we lay out walls on the actual deck- conformity to reality
    2. Show 1st segment of layout video (5-8 minutes); take questions
    3. Lay out exterior walls first, then interior walls- marking system
    4. On markerboard, Jim shows how to mark plates for one corner, illustrating one exterior door and one window
  1. Hands-on demonstration by participants on stud-length plate marking.
    1. Break into 4-5 groups of 5 people; each group gets one 8 ½ x 11 paper plan with layout task similar to markerboard example. Regroup for questions.
    2. Ten-minute break for coffee & doughnuts
    3. Questions from participants about their exterior wall layout
    4. Video segment #2 about interior walls (5 minutes); take questions
  1. Jim then shows on markerboard-
    1. Interior wall intersects an outside wall; contains closet. Jim explains interior door headers; double 2x4s
    2. Porch beam concept- what it is, how it fits beam pocket, why it must be square and level, framing the beam pocket
  1. Quickly break into groups again for different hands-on demonstration
    1. Some will do interior wall plates, some will calculate small porch beam.
    2. Reassemble for questions/answers
    3. Brief discussion of other layout opportunities:
    1. layout of floor joist –on rim joist and sill plate- start at the plumbing wall
    2. layout of roof trusses- on the double top plate; truss plan and what’s important
  1. The Six uses of a stringline in building a Habitat House (Jim write string limerick on markerboard)
    1. masons use string for block (prior to dig, stringlines used to mark)
    2. carpenters use string to check beam level
    3. after walls are raised, long walls are strung before bracing
    4. string across top plates to check center partition height prior to truss setting
    5. string used to make truss setting consistent
    6. chalkline string makes first course of roof/ floor decking correct
  1. Framing problems we’ve had- Troubleshooting
    1. deck longer or shorter than plans- how to fix this
    2. house wider or narrower than plans- how to fix this
    3. importance of bathroom(s) walls- fix/start with them; hall width must be maintained at 37 inches
    4. porch beam out-of-square- consequences for small trusses
    5. center partition too high- trusses rock
    6. one truss short- how to cut rafter with birdsmouth
    7. truss spacing inconsistent or leaning
  1. If I were an architect
    1. why it is difficult to add fractions
    2. questions- take the quiz; win a prize more video/dismissal for lunch- help clean room & prepare for the buffet
