Building Technology II ARCH2331, F2024

Question:
What is the building’s height that we are currently making the plans and elevations for?

Solution:
Utilized the elevation drawings of maison Gartte-Cie case study project on OpenLab. You know the long East-West dimension (55’) from the dimension diagram. Use that information to scale the elevation drawings. You are encouraged to do more research on the case study building including it’s dimensions, consider searching for more drawings and evaluating building pictures.

Student question:

“…. my structural grid is printing as solid lines instead of the grid line type, I did everything I could to change it but I just can’t seem to fix it, the model space is fine, it’s just the paper space that’s messed up.”

Solution:

There are several ways to adjust line properties, so they print dots and/or dashes.

Here are 3 ways that I think are most useful.

you can type the command  “PSLTSCALE” to turn off and on the scaling line command. When on the line should scale to the Scale you’re using in that particular viewport.

MSLTSCALE To adjust line scales in model space

PSLTSCALE To adjust line scales in paper space

or

You can right click a line and go to its properties and change its “Linetype scale”.

Question:
I had a question about the thickness of the batt insulation in the roof. You asked us to make it thicker than our deepest joist, in my case 220. However, I am not sure what can hold it. For example, the image I attached shows that the joist is flush with the slant of the roof, if I give ore space for insulation what can I add so there wouldn’t be a gap above the joist? Double studs (47×75)? If so, how far should I space them from the joist?

Response:
See the attached sketch in particular the parts labeled A, B, C, and D.
Because roofs tend to be the surfaces you lose most of your conditioned air it is the area that should have the most insulation if possible. The overall insulation area should be equal or greater (B>A) to achieve this you can put your roof furring strips (D) at a distance from your rafter. To support your roof furring strips you can use 18mm OSB or plywood (C) to connect them to your rafters.

Question: I was trying to calculate the beam to use in my building. Can you check the attachment to see if it’s correct?
Answer: Yes, that works with the table Architect Studio Companion

Question: I also need help with finding the width of the beam.
Answer: A beam with is from 2 to 7 times smaller than its depth depending on the beam length. In your example dividing the death by three would equal roughly 5.25” would be a good estimation.

Question: Is it okay if my exterior walls for the Cooper Residency are 13” thick and the interior ones 6”?

Response: Yes, 13” is a good estimation of what a high performance wall might equal. Interior walls are typical typically just under 5” (4-3/4”) so that is a good number to work with.

A good start, I can review drawings online during class.

some quick thoughts on improvements:

• you should add a heavy weighted that line indicates the ground level.
• the lines of your cantilever are too heavy
• you should add elevation markers to show the relative Heights of the building
• You do not want to use multiple lines for the curves
• Give at least 8 inches of thickness to your slope roof
• With a dash line you can add the outline of the Cellar level

Question1: I was trying to figure out how to put grid on the image can you please tell me. Response: Can you be a little bit more descriptive with your question? The grid should be drawn using the grid line template as indicated over the drawing. Copy the grid lines in the template and placed them over the image in a way which makes logical sense to the structure of the building. Think about the way the structure of the building works addition to what is represented in the drawing. Remember to use the dimension lines in between the column lines. Copy them and place them in between the grid lines and stretch them to the correct length.

Question2: Assignment 1 due 9 pm, but I saw the assignment is due 9 am on Sunday. Response: The due time is fixed.

Question: Where on blackboard should we post and should we hatch the walls on our drawings?

Response: You will now find and upload location in the content section of the class blackboard site. Do not hatch your walls, use heavy line weights for your cut walls. Walls are typically only hatched on some presentation plans not on construction plans. When they are hatched there usually filled in.

Question
How far does the key go into the footing?

Response
Concrete of type the typical for foundations well in increments of an 1/2 inch. Smaller increments have a risk of not casting properly. A good key to mention for this project would be 3 inches on top by 2 inches in depth by 1.5 inches at the base.

Question:
I was wondering what the king stud is supposed to look. Could I get a photo of how a king stud supposed to look at windows, and doors?
