chalkline, string line, markers
- Blueprint Reading Distribute old HFH house plans
origin

- Discussion of front/side elevation, floor plan, foundation plan/site
plan, electrical plan, truss plan. Questions?
- 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
- Brief discussion of 3 major HFH house plan design models; 3J, 4B,
3G; other models 4F wide and 3HC handicapped
- 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
- The Floor Plan- shows all you need to know
- Why we lay out walls on the actual deck- conformity to reality
- Show 1st segment of layout video (5-8 minutes);
take questions
- Lay out exterior walls first, then interior walls- marking system
- On markerboard, Jim shows how to mark plates for one corner, illustrating
one exterior door and one window
- Hands-on demonstration by participants on stud-length plate marking.
- 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.
- Ten-minute break for coffee & doughnuts
- Questions from participants about their exterior wall layout
- Video segment #2 about interior walls (5 minutes);
take questions
- Jim then shows on markerboard-
- Interior wall intersects an outside wall; contains closet.
Jim explains interior door headers; double 2x4s
- Porch beam concept- what it is, how it fits beam pocket,
why it must be square and level, framing the beam pocket
- Quickly break into groups again for different hands-on demonstration

beam.

- Brief discussion of other layout opportunities:
- layout of floor joist on rim joist and sill plate-
start at the plumbing wall
- layout of roof trusses- on the double top plate; truss plan
and whats important
- The Six uses of a stringline in building a Habitat House (Jim write
string limerick on markerboard)
- masons use string for block (prior to dig, stringlines used to mark)
- carpenters use string to check beam level
- after walls are raised, long walls are strung before bracing
- string across top plates to check center partition height prior
to truss setting
- string used to make truss setting consistent
- chalkline string makes first course of roof/ floor decking correct
- Framing problems weve had- Troubleshooting
- deck longer or shorter than plans- how to fix this
- house wider or narrower than plans- how to fix this
- importance of bathroom(s) walls- fix/start with them; hall width
must be maintained at 37 inches
- porch beam out-of-square- consequences for small trusses
- center partition too high- trusses rock
- one truss short- how to cut rafter with birdsmouth
- truss spacing inconsistent or leaning
- If I were an architect
- why it is difficult to add fractions
- questions- take the quiz; win a prize more video/dismissal for lunch-
