Took Building Technology last Tuesday the 17th. It takes approximately 6 weeks to get exam results. I'll be studying for my next exams in the meantime, so we'll see.
More life and work delays, blah blah blah . . . new exam order as follows:
Site Planning - tied to pre-design
Pre-design - Has been touted as a summary exam of all other tests. tied to site planning
Mech/Elec - tied to Building technology
Building Planning - this is a one for one change over so no other tests are at risk, I may even take it in v4.0
Structural v4.0 This is one test instead of two in v3.1.

Bldg Tech - Roof Design: 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
Roof Design
Scope:
- Upper and lower roof: Calc. clng. ht. + structure thickness + clerestory
- Clerestory requirements
- Roof plan slope requirements
- Flashing at roof to wall and roof to chimney intersections
- Crickets at Chimney if required
- Skylights (per program)
- Gutters outside of roof edge
- Downspouts, avoid windows, doors, show at wall area only, provide one each end at long lengths.
o also provide at high roof to low roof if applicable
o watch out for porch and columns
- HVAC, locate per program requirements
- Exhaust vent, locate per program (not in wall)
- Plumbing vent stack, per program (back to back bathrooms can share)
Fatal Errors:
- Missing elements
- Clerestory location
- Overlapping roof planes (use check tool)
- Improper roof slopes (use least allowed per program)
- Natural light requirements for rooms without windows
- Highest ridge height
- complicated roof: keep it simple stupid (not grading on design)
- Poor HVAC location
- Improper roof elevations: See calc note above
- Downspout locations: see notes above
- Too much volume: minimize differences between clng heights and roof elevations
- Surfaces sloped in wrong direction
- Crickets per program
Personal Notes:
- Make an itemized checklist from the program
- Draw roof plans and all other elements
- When you think you are finished, run through the checklist and verify all is provided
o and verify that all is provided per program, slopes, skylights, etc.

Bldg Tech - Stair Design: 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
Stair Design
- Provide one continuous stair, from 2nd level to intermediate, from intermediate to 1st level at grade
- Code problem
o Real exam will be mostly the same as practice problems
o Ability to calc stair load
- Curveball
o watch out for new code requirements
. usually in area of refuge (AOR)
. May call for one at 2nd floor
. or may call for one at EACH primary landing
- Do the calculations
o width by occupancy
. railings can extend into the stair width 4" on each side unless AOR is required
o minimum width by code
o AOR requirements
. 48" clear of rails
. add 4" ea. side to 48" = 56" wide stair, min.
- check maneuvering clearances at doors
- check door swing encroachment at stair landing
o cannot reduce required landing length more than half
- check headroom clearances under landings
- Railings
o use your zoom tool
o don't forget to connect and extend 12" at top and bottom
o ok to encroach into egress width 4" ea. side
o don't encroach on AOR 30"x 48" CLEAR!
- Stair Riser
o between 6-7", and equal
o keep all same, can be different from run to run but entire run MUST match
o multiply elev. change foot x 12 + inch remainder, divide by 7 and round up one
- Stair Run
o Use the stair tool, input number of risers, when drawing, stop when tread reads 11 inches
- Stair Cuts
o Use them and practice
o Draw at each level as if drawing solid stair
o don't forget to draw railings up to cut line
Personal Notes:
- Use sketch rectangles everywhere
- Check clearances at ALL 1st level doors and Path to exit
o Doors not part of stair: Do not encroach door landing clearances with stair/landing layout.

Bldg Tech - Mechanical / Electrical Layout: 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
Mechanical / Electrical Layout
- Two issues being evaluated (don't inter-relate)
o light spacing
o diffuser and ductwork layout
- Know how to read a lighting chart
o Shows how many foot candles at a certain height
o spacing is dependant on ceiling height in program reqt's
- NON-requirements
o no need to light accent walls
o Furniture layout is not relavent to lighting layout
- Tricks
o go room by room
o use sketch circles to layout room (I haven't found this usefull)
. 6' dia. circles = 4' light separation (check program)
. move group of circles until centered in room
. drop 2'x2' fixtures in center of circles (make sure program doesn't require ONLY
2'x4')
o Add grid to layout and adjust as required
. grid from wall, 1' min. and 4' max
o every 144sf of room requires one diffuser and on return grill (check program)
. use id button and click grid to get square foot area of room (be sure you've drawn grid correctly.
o grid overlaps column corners
- Efficiency
o Rigid duct does not fit under joists
. must go between joists or parallel within 2' of BEAMS and BEARING walls.
. minimize lengths, layout for economy and maximize endrun with flex duct to reduce use of rigid
o flex duct from center of diffuser to rigid
. 10' max run
o connect return riser with rigid duct, poke through wall into ceiling space
o Don't forget fire dampers
. they point in direction of air flow
o keep 4' min. separation between supply and return grilles
. support grilles on 3 sides with grid
Checklist (in this order in my opinion)
- Grid in all rooms
(zoom in and scroll bar to each room, doing one task at the same time saves from switching between tools each time)
- align/rotate grid within each room
- Calc lighting separation and Place
- Draw rigid duct (minimize amount, center at rooms if possible)
. don't forget return
- Calc number of grilles required for each room (make list) and place.
. put supply closer to rigid to reduce flex duct run (ignore good practice of supply furthest from doors and near windows if you have to)
- connect flex duct from center of supply to rigid
- don't forget fire dampers

Bldg Tech - Ramp: 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
Accessibility Ramp
- Review Program & Code
o Make shorthand notes of specific requirements
o my last mock exam i made fatal flaw of doorswing from corridor to lobby drawing them based on the language in the program "provide wall and doors connecting the Lobby to the corridor". The swing was in the opposite direction of the egress path, FATAL FLAW.
- Keep solution simple, orthogonal
- Look for clues
o Doors, how many are shown
o Don't reduce exit clearance on ramp, keep all ramps same width
- Watch for obstacles in layout
- Use sketch tools to layout ramps and landings
- Consider exiting circulation
- Computer grader looks at residual spaces, make sure they are accessible
o this does not mean ADA, if you have solved correctly there won't be any wierd unusable leftover spaces.
- Don't overbuild: provide minimum requirements
- Changes in direction require 5x5 minimum landing, 60" circular clearance is under much debate on the forums, it's safer to provide the clearance between the railings and not let encroach.
two issues (90d turns & 180d turns):
o 90d turns require 60" square, ramps can be widened to 5'.
o 180d turns require 60" CLEAR circle, provide deeper landing at these locations.
Fatal Errors:
- Program
o missing elements, check all rails, include at landings +6" or less
o don't violate edge of existing slab
- Design Logic
o more than one stair/ramp
o residual space unusable
o Inefficient solution, incorrect slope, not meeting code minimum
o unclear circulation
- Code
o New doors swing in right direction
o Riser height and ramp slope
o stair/ramp too narrow
o missing railings
o missing railing extension
o Landings too small
o circulation obstruction
o Clearance at virtual landings, top and bottom
- Extra Notes
o Unclear issue, existing landing, do not reduce width of existing landing. Instead draw new landing up to it maintaining it's existing width.
o ie. don't have railings overlap existing landing
o See code note "No portion of the ramp or stairs may encroach on the existing upper level".
o there have been many discussions as to acceptability of utilizing the existing landing but it boils down to going safer route.
o Ref: REF LINK
o added door does not need to be double, wall with single door is deemed safest route by forum members.

Bldg Tech - Structural: 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
Structural (general)
- Only design for vertical loads, no lateral (pretend you're on the moon)
- Watch for two level roof
- Read entire program, make shorthand notes of requirements
- high ceiling areas
- clerestory location, etc.
- Show all elements of support (think checklist, see below)
- Identify high ceiling roof (see program)
- Dorf suggests column and beam only
- Bearing walls and Lintels can be used but can be more complicated
- Personally I only suggest for low roof structure
Drawing order:
Lower level:
(note: Dorf suggests starting at Upper, I prefer switching between upper and lower plans a couple times to get familiar and starting at lower. Do what's comfortable to you.)
(time saver note: draw all of one element at the same time, zoom into one room and pan around with scroll bars at side and bottom of screen. This will save from switching to different tools.)
- Bearing walls first
- Most solutions can be solved without bearing walls, use at your own risk
- Don't use at window walls
- No bearing walls on top of col's BUT col's on top of bearing walls acceptable
- Don't forget Lintels: Extend into wall 4-6 inches
- Columns next (or first if not using bearing walls)
- See timesaver note above
- Layout for maximum spans (typically not in program)
- See Joist and Beam below
- See program but typically ok in window walls and clerestory.
- Must be in walls/window, NOT in open space or openings
- Beams: ~20'-40' spans +/- is considered economical
- Extend beams to middle of column, DO NOT stop at edge of column
- Beam can be continuous over intermediate columns
- Joists = ~30' span range is considered economical
- Span in shortest direction, keep all spans same direction if possible
- Joist spacing = Max Deck span in program requirements
- Move/adjust joist spacing layout to middle of existing walls on ALL sides
- Ensure Joists are showing at parallel endwalls to provide decking support
- Provide bearing at end span walls perpendicular to joists only, none required at parallel walls.
- Decking: draw to middle of existing walls / new beams
- Runs perpendicular to Joists
- Clerestory: Dont' draw on lower level but:
- Don't forget beam at this level under clerestory for support, check program for clerestory location.
Upper Level:
- Columns: draw and stack over lower level colums at high roof area
- Beams: if you add any columns to reduce spans, be sure to add it on lower level plan too.
- see beam rules above
- Joists: See joist rules above
- check program for high roof requirements
- Decking: (Don't forget the decking!)
- See decking rules above
Fatal flaws:
- Missing elements
- Columns inside rooms (keep in walls)
- columns in openings
- clerestory location
- too many columns
- over structured
- redundancy
- un-needed bearing walls / beams
- over max spans
- Upper columns missing columns below
- column offsets (asume this means upper and lower not aligning (zoom people!))
- Beams / Joists: be sure they overlap bearing structure, nothing stops adjacent, everything sits on something
- beams onto columns: passover or to middle of end column
- joists to center of walls/beams: align joist over ends at non bearing parallel walls (how else will you support the decking)
- decking to center of walls
- Bearing wall openings, Don't forget the lintels, make sure they overlap the wall 4"-6"
Checklist:
- review
- program (take shorthand notes)
- review plans (switch between upper and lower)
- some requirements will show up in plan that are not mentioned in the program and vise versa
- draw stacking columns on both levels
- beams or bearing walls at all perpendicular joist bearing points
- Lintels in bearing walls
- beam at lower level to support under clerestory
- Joists
- Decking

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.
- Click here for detailed description see comment posted on Sun Mar 15th by Sinkwcal
- 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
Studying for Building Tech. Exam
I take the exam this Tuesday, 3/17.
I studied for 8 hours yesterday, ran through all of the tests and posted them to the areforum for feedback.
I feel pretty good about them except I need to do the following:
- Better my timing on the section, mech/elec & stair tests.
- List requirements to avoid fatal flaws, ie. forgetting roof decking on structural test.
Today, i will be typing up notes on the Dorf seminar notes. only items that will have a benefit to my memory.
Then i will retake all mock exams again.
cheers!

- List requirements to avoid fatal flaws, ie. forgetting roof decking on structural test.
Today, i will be typing up notes on the Dorf seminar notes. only items that will have a benefit to my memory.
Then i will retake all mock exams again.
cheers!
