Bldg Tech - Section: Dorf ARE Graphic Workshop Summary of Notes

(Note: This is MY summary of the notes notes from the Norman Dorf ARE Graphic Workshop, for complete notes, visit the areforum.com ftp site.)

Building Technology Division

General

- Don't tweak your designs if you have extra time - you will run out of time, most likely in the middle of tweaking.

- computer does not grade on quality of design, only check against code/program data

Building section

- Read plan with all layers on

- Draw section over plan right below cut line.

- Draw grade first

- Draw slab on TOP of grade

- Slab is discontinuous between bearing/stem walls

- Draw footings (check frost depth requirement)

- perimeter footings: stem wall starts at top of slab, top of footing aligns with frost depth

- frost depth: measure from grade line, not top of slab

- interior footings: be sure to place at any bearing walls as indicated.

- Stem breaks slab

- Top of footing aligns with bottom of slab & grade line, unless program states otherwise

- Ceilings: Draw sketch lines/rectangles for required ceiling height first

- Draw ceiling line

- Draw lighting clearance sketch rectangle (usually 8" but read program)

- Duct / joist size: Look for largest joist/duct COMBINATION that share common ceiling area in entire floor area.

- Draw sketch rectangles again for duct(even though that size duct may not show up in the actual section) and joist

- Draw joists: check size being cut through and direction

- be sure to move to align with layout on plan

- overlap halfway into bearing walls

- Draw ducts being cut: put right under joist

- Non-rated & Non bearing wall Partitions: stop 6" above ceiling line & cut ceiling

- Rated wall partitions: cut ceiling line and stops underside of floor/roof deck above

- For 2nd floor and high ceiling spaces, repeat ceilings and duct/joist size above

- Don't forget parapets, see program for required height

Common Fatal Errors

- Missing Program requirements: Read thoroughly and write a checklist, also, check it off as you go or at end(when you think you are finished)

- Missing elements: Ducts, Partitions, Interior Footings, Parapets (see checklist)

-Joists spanning in wrong direction

- improper dimensioning: check and re-check floor & roof heights

- Technical errors:

- Footing depths

- Rated partitions & their height

- Joists NOT supported on walls, Carry into wall 4-6 inches
