Recieved my pass letter for Building Technology yesterday!!!!!!!!!!!!
I thought I had passed it but you never want to be so sure until you get the pass letter.
Whew...
Ok, so on further review, I have decided to switch to only taking one more test before the end of June and taking the others in version 4.0.
So I will be switching to Mechanical and Electrical Systems since it is linked to Building Tech.
I realized by trying to take Site Planning and Pre-Design before the end of June I was needlessly putting both of those tests at risk for failure since my schedule for study time would have been much shorter than it should be.
Sorry for those that may have been following my Site Planning notes but I will pick it back up later.
Bye for now...

Site Grading Dorf Solutions Summary
Description: test ability to interpret and modify site topography to conform to a given set of program requirements.
Considerations
- Site elements may include parking areas, driveways, existing excavations, existing building structures, level OR sloped building pads, existing paved areas, sidewalks and the like.
- existing contours at 1’, 2’ or 5’ increments, probably 1’ intervals
- existing side streets at fixed elevations
- trees and/or other natural site features
Recommendations
- Understand site contours, slopes, swales, berms, crowns or ridges and how to manipulate contours is the main importance
- Check site plan first, learn what interval the contours are set at, this effects the distance needed to be maintained between them
- Use the sketch tools to measure distances between existing and modified contours
- Sketch center lines of proposed swales prior to manipulating existing grades
- A zoomed look at the site, note conditions and elevations of existing elements prior to manipulating contours
- Use sketch circles to represent req’d distances between contours to meet the program.
- PARKING LOTS: Drainage within a lot MUST be consistently handled with equal separation of contours to ensure a smooth flow of water to the sides or to a given point of collection.
- Swales may be used on the sides of the lot to direct the run-off
- Positive drainage from a level area requires the next lower contour to “surround” the entire level area.
- Use swales also to direct the water from there
- If a sloped surface is to remain sloped, do not change the contours in that area
- Water up slope of a given level paved area should not be allowed to flow onto that paved surface
- Note existing street grades, DO NOT ALTER
- DO NOT ALTER contours in tree drip lines
- Swales are indicated by contours “pointing” UP the general slope, lower numbered contour points up toward higher numbered grade contour
- Crowns “point” down the general slope, higher numbered grade contour points down toward lower numbered grade contour
- Grades must not be altered beyond the property lines shown on the existing site plan
Scoring issues
- draw max and min slope requirements accurately
- drainage is properly directed around features as programmed
- Do not disturb trees, stay clear of drip lines
- Don’t alter contours past prop line
- Existing street and site feature grades are noted but not altered
- Contours do not cross or split
- Crowns are shown to direct water off roads or parking lots, unless otherwise programmed
- Swales or crowns have been indicated correctly
- Contours are EVENLY spaced on surfaces requiring a uniform, constant slope

Site Zoning Dorf Solutions Summary
Read and took notes on 4/20 between 9:45pm-11:15pm for 1.5 hours
Description
- Tests the understanding of zoning and other setback restrictions in plan and in section.
- Task 1, You will receive a program, site plan, cross-sectional grid and be required to draw areas suitable for construction of buildings and areas suitable for surface improvements on two separate lots
- Task 2, Site section, draw existing grade profile and max. profile of the two buildings (above grade)
Considerations
- profile of the existing grades
- location of the section cut line
- legal front yard, side yard, rear yard setbacks from existing property lines
- easements, view corridors, other restrictive building areas
- setbacks from natural features, tree lines, well points, existing buildings
- the delineation of suitable building areas, and
- the delineation of suitable surface improvement areas
- height restrictions
- solar-access planes
- restrictions on which grade elevations buildings can be placed
Site Analysis Recommendations
- Must be completed before attempting to delineate the profiles of the buildings.
o There is only one correct solution to this portion, be sure to follow program EXACTLY or will get downgraded or fail
o No subjective thinking options, just one answer
- Thoroughly review existing conditions noting ALL plan notes or dimensions
- Setbacks are measured perpendicular to given elements, even when curved
- Use sketch tools to show construction limits and setbacks
- 10’ grid tool is valuable, USE IT.
- Determine setbacks for irregular shapes with sketch circles
- Two tasks, show building allowable area of coverage, show surface improvement allowable area of coverage
- Do each task separately, use layers
- Typically, easements will be available for construction of surface improvements, but not always, READ PROGRAM
- Accuracy is a main ingredient of solution even though the software may prohibit
- Look for small areas that still may be within setbacks, they will count
- Use “ortho” tool whenever possible, it’s faster
Site Section Recommendations
- draw existing grade accurately
- sketch tools for various height or setback limitations on the grid
- be sure to accurately the bench mark elevation as it is important in location of other elevations
- use ortho
- only one solution, check for accuracy, then check again
- angled sun exposure lines or planes can be determined by using a sketch line and drawing it at an angle, draw line at correct angle using triangulation
- EXTREMELY important to take notes of the various restrictions, DO NOT TRY TO MEMORIZE, a single error will be fatal
- Building profiles required are all above grade, it will not be necessary to trace over the existing grade line
Scoring Issues
- setbacks and height limits are properly and accurately shown
- front yard, side yard and rear yard setbacks are measured from property lines
- buildable areas (both buildings and surface improvements) are MAXIMIZED
- easements are respected per program
- measurements are reasonably accurate
- grade line is drawn reasonably accurate
- Since there is only one correct solution to this problem, any deviations will be downgraded, or if serious will trigger a fail. Mistakes on the site plan portion of this vignette will cause profile errors
Task 1 approach (site plan)
turn on 10’ grid
sketch limits per grogram perpendicular from elements, circles may be helpful for curved or odd shapes
Task 2 approach (site section)
draw existing grade, check scale of grid, it MAY differ between horizontal and vertical
use sketch tool to drop points that correspond to grade elevations at cut line
connect the points with straight segments with the draw grade command
OR
immediately enter draw grade command, use full cursor and click on the points as you go, this takes practice but may save some time
Draw all required lot line setbacks, easements, height restrictions, bench mark (ON BOTH SIDES OF SECTION), solar access planes, etc.
Take care in locating point where solar access plane initiates. It should be accurate, zoom in if necessary
outlining maximum volume of buildings should be straight forward after this point
Site analysis tips
- ‘surface improvements’ can occupy same area as the ‘building construction’ since they are on separate layers
- For speed make use of ortho 10’ grid and eyeballing 5’ setback increments
- Draw segmented lines for setbacks at curved elements, use sketch circles to help
- If more than one street, the program will indicate which is considered the ‘front’
- Buildings may be built over easements but generally only improvements will be allowed
- Keep within 1’ tolerance for showing setback restrictions
- Not required to leave both layers on before exiting vignette
Building profile tips
- area most likely will not be completely orthogonal, must show correctly, use sketch lines
- building outline starts and ends at a part of the grade, do not trace the grade too
- grade line does not need to show beyond the property line, but may help get a more accurate profile where it meets the property line
- use move / adjust tool to fix grade line if inaccurate, do not redraw
- use line sketch tool for sun exposure plane, stretch for more control and accuracy
- do not square off limits with an angle, draw them with the angle
- stay within 1-2 feet tolerance and 1 degree for angles
- use sketch circles as required for setbacks
- most time is dedicated to setting sketch elements for limits, drawing actual limit outlines and grade will take less time
- no need to hide sketch lines when leaving vignette

Site Planning Dorf Solutions Summary
Read and took notes on 3/19 between 4:15pm-6pm for 1.75 hours
- Three vignettes:
o Site Design – First section, 90 minutes then mandatory 15 minute break
o Site Zoning – Second section, 60 minutes
o Site Grading – Second section, 30 minutes
o You may not switch between vignettes in the first section but you may switch between the two vignettes in the second section as you wish
- Site design tests your understanding of general site planning principals, vehicular and pedestrian movement and safety, design logic, zoning and technical reqt’s to produce a cohesive and competent design. DON’T EXPECT TO ARRIVE AT A “BEAUTIFUL” SOLUTION WITHIN THE TIME LIMITS….. BUT YOU MUST MEET THE PROGRAM REQUIREMENTS!
o You are given a program, a site plan and conceptual footprints for 2 or 3 buildings and other site elements such as sidewalks, roads, plazas, trees and parking.
o From these you must produce a schematic site plan.
o Parking with drive-through circulation is a part of this problem, includes ADA spaces.
o Considerations to take into account
§ Easements, utilities, rights of way
§ Building limit lines
§ Trees, vegetation, rock outcroppings, wetlands, water & setbacks
§ Winter (or Summer) prevailing winds
§ Adjacent residential (quiet areas), academic and/or commercial uses.
§ Views
§ Setbacks from site elements
§ Primary and/or secondary road systems
§ Existing structures
§ Sun angles
§ Shadows from existing, or new, site elements
§ Curb cut(s)
§ Service drive(s)
§ Passenger drop-off
§ Pedestrian circulation
§ Vehicular / pedestrian conflicts
§ Special relationships between new elements or existing conditions
o Recommendations
§ Zoom in on existing site plan provided, verify notes, critical dimensions, site features and the nature of surrounding properties and streets
§ Use sketch tool to draw setbacks or other restrictions
§ Place all new programmed elements on screen to gain a sense of scale.
§ Let the program and site constraints “work” for you; follow the program exactly’ take “advantage” of the site restrictions, views, wind direction, solar needs, and so forth. There is no one correct answer on this vignette, many ways to solve, don’t fight the program, don’t try to be a great designer.
§ Use appropriate trees for blocking views and winds (conifers/evergreens), or for shading (deciduous/broad leaf/ seasonal).
§ Keep solution efficient, obvious and cost effective.
· Separate “service” drives from the parking lot access immediately.
· Design a simple, safe roadway system; don’t abuse the site with unnecessary roads, i.e. Save grass
· Keep noisy service trucks away from quiet residential areas if possible.
· Design parking lots with double loaded perpendicular parking to keep size to a minimum
· Design an obvious and simple pedestrian walkway system from existing sidewalks or between building elements
· If an element requires sun at NOON, then it must face SOUTH. Be direct if site conditions permit.
o Scoring issues
§ ALL program required elements are shown
§ Sizes of elements meet program requirements (within tolerances)
§ Relationships between elements reflect program needs
§ Programmed views or screens are provided effectively
§ Setbacks, easements and building limit lines are respected
§ Entrances to buildings are oriented properly
§ No more trees are removed than permitted by the Program
§ Accurately reflect sun or shading requirements
§ Effectively block prevailing winds where necessary
o Code
§ Parking, drives, buildings or building expansion do not infringe upon or overlap any legal easements or setbacks
§ Site improvements are not located on sloped areas, or where otherwise prohibited from construction
o Design logic
§ Programmed adjacencies are met (building to building, parking to entrances, service to service entry, etc.)
§ Entrances are viewed (or blocked) per program.
§ Programmed elements do not overlap
§ Vehicular circulation system is efficient and safe
§ Pedestrian walkways are accurately provided between elements
§ Safe pedestrian circulation
§ Curb cuts logically located
§ Efficient parking (double-load) when possible, safe, and drawn to an appropriate size and configuration. Avoid dead-end parking, allow for drive-through circulation
§ Only 90d parking indicated
§ Access to parking is not blocked by service vehicles
§ Handicapped spaces are located closest to entry and do not require crossing traffic aisles to reach entries
§ Use enough trees to solve the program issues, not too many
o General Site Planning tips
§ Conifer trees block wind and views; avoid placing in front of required views.
§ Deciduous trees do not block wind or views, use for shading only
§ Do not over plant, use new trees only to meet program requirements
§ All new elements “kill” existing trees including sidewalks
§ Use a double row of conifers to block wind only when perpendicular to the wind direction
§ Service drive should be at least 20 feet long
§ No elements may violate setbacks, not even sidewalks
§ Use tree profiles in program to determine sun angle and shading
§ Trees may be planted in plaza if needed to meet program
§ The words “close to” and “near” should be considered within 10%-20% of site dimension
§ Avoid violating easements
§ Conifers blocking wind of a specific element should be placed near rather than farther away
§ Stay within 5% - 10% for square footage requirements
§ Only plant tees required for program, not to enhance design.
§ Minimize roads and walkways
§ Even avoid new trees in setback areas
§ Plaza shape is not rigid, just meet the SF requirements and all others
o General Parking tips
§ Do not provide walks from parking to the street unless specifically required.
§ Walks not required around parking lot, only at Handicap spaces.
§ Locate Handicap spaces closest to entrances
§ Locate handicap spaces adjacent to walkway and DO NOT cross driveways
§ Drive through circulation means loop, no dead ends
§ Measure 90d angle requirement at existing road by “eye” but don’t be sloppy.
§ Adjusting new access roads is difficult in the software, try
· Drawing roads in several separate segments
· Use sketch circles to locate centerlines of required road locations
§ Roads kill trees, avoid drip lines
§ Single loaded parking is permitted but avoid due to inefficiency
§ Only 90d parking spaces are acceptable, no angled or parallel
§ If drop off required, road does not need to be widened, but note that they are provided that passengers are dropped off onto curb
§ Again, no dead end parking is permitted
§ Service trucks may NOT use parking lot to gain access to service entry!! Parking lot is for passenger vehicles only
§ Being short or providing 1 or 2 more stalls most likely will not receive a fail
§ Follow program for curb cuts, usually only one per program

Site Planning Exam - Dorf Notes
Ok, here's my first post for site planning.
Site Design
- Practice, Practice Practice, especially drawing roads.
- Stay away from easements
- Look for wind locations
- Verify direction of North arrow
- Stay within building limit lines
- Don't guess program requirements, always verify and make shorthand notes
- Place objects on screen to get a sense of scale
- 30-33 car req't is typical
- analyze parking, 120x120 or 150x100
o get a sense of scale
- try to stay away from diagonals
o Be efficient in numbner of trees
o Possible downgrade if too many trees are used
o Use them to serve a function
- Plant deciduous trees to shade the sun
- Locate ADA to access sidewalks immediately
- Plant trees on the plaza if there is a question that requires the plaza to be in shade at NOON
Site Zoning
- two primary tasks
o where can i build a building
o where can i do surface improvements
- read carefully and take notes - sometimes wording is difficult
- sun exposure plane will be on test
- take notes - save time from going back and forth to program
- there is only one correct solution
Site Grading Vignette
- be alert to scope on site
- good chance only dealing with swales
- must know how to manipulate grades
o swales point up hill
o crowns point down hill
- stay away from dirp line of trees
- look out if the problem involves a new object with a set elevation
o will require wrap around swales
- slopes / grading - common:
o 5% 1:20 1 foot rise to 20 feet of run
o 10% 1:10 1 foot rise to 10 feet of run
o 20% 1:5 1 foot rise to 5 feet of run
o 25% 1:4 1 foot rise to 4 feet of run

Study Site Planning Tonight
I'll be reviewing Dorf notes and updating Site Planning info on the blog tonight.
Thursday, March 26, 2009
Schedule Update: 3/26
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.

(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
