Structural Framing Essentials for Upper Floors and Roofs with Joists and Glulam Beam Takeoffs

Detailed Takeoffs for Roof and Ceiling Framing Using Joists and Glulam Beams in Guest and Music Rooms

Discover the process of determining the main structural components of a construction project, with a focus on identifying floor joists, major structural posts, and floor sheeting. The article delves into the details of reviewing sheet S4, completing the structural floor joists, and progressing with the structural plan for the roof level.

Key Insights

  • The article primarily discusses the evaluation and identification of main structural components in a construction plan, particularly floor joists, major structural posts, and floor sheeting.
  • It explores the detailed examination of sheet S4, which includes the structural plans for the roof level. This includes the specific calculation of joist counts and lengths, with an example from a guest room roof framing scenario.
  • The construction plans also call for consideration of other specific elements such as glulam beams in the music room, highlighting the need for meticulous review and understanding of architectural plans to ensure accurate estimation and ordering of construction materials.

Note: These materials offer prospective students a preview of how our classes are structured. Students enrolled in this course will receive access to the full set of materials, including video lectures, project-based assignments, and instructor feedback.

All right, and moving along, we just finished the structural floor joists on sheet S3. Now we can jump into sheet S4 and do the same thing. And just a note, there are a lot of very kind of like intricate details of these structural sheets, and we could spend hours just taking off these structural items down to the nuts and the bolts and different hold downs and things like that.

We're not going to get into that level of depth in this course, but we really are going to just make sure that we capture the main structural components here. So things like floor joists, things like some of the major structural posts that are holding this up, as well as the floor sheeting that goes over it all. So what we're going to do now is we're going to go into sheet S4 and we are going to continue with floor joists.

So sheet S4, we can see the floor and roof framing plan. We are doing the structure to hold up the roof level right now. And let's look at the guest room first.

And we can see that we do have a similar type of joist as we do on the floor below. We have this 11 7 8 inch TJ1 over 360 joist at 16 inches on center, similar to what we had below. It's just running in a different orientation.

So let's go into our length here and we already have the scale set properly. We've confirmed that. Let's just go ahead and grab the length of this particular joist.

And it looks like it is 22 feet 2 and 3 quarter inches. Okay. And let's go over into properties here.

And we still do have the name saying guest room. That's great. Let's take this count off because this was for the previous.

And all right. So for this particular one, let's just say guest room roof framing. We know that we're differentiating from what we've done on the previous floor.

And to get a full count of how many of these we need, so this one is, oops, sorry, I navigated away from the page again. Go back to where I was. There we go.

So to understand, since these are at 16 inches on center, how many of them we actually need, we're going to go ahead and grab our length here. And we're going to go from outside to outside. And it's going to come in at 20 feet 9 and a half inches.

So again, grabbing the phone and doing some quick math here, we have 20 feet times 12. That gets us to 240 inches. We're going to add 9.5 inches in to 249.5. Let's go ahead and divide that by 16.

Once we divide that by 16, we get to 15.59. And we're going to round up to 16. So because we cannot have a half of a joist here. So let's delete this that we were just using from a length calculation standpoint.

Let's go back into our joists. And let's go into properties. And okay, we have the name of it.

We have it designated at the guest room roof framing instead of the floor framing like we did on the previous. And let's just say a count of 16. So great, we have that all straightened out here for the guest room.

And let's jump into the music room. And we'll do the ceiling framing on the music room. And we can see that we have many beams that are running kind of horizontally across here.

And when we look at the description here, it says 3 × 7 and a half inch glulam beams that are typical. We see that there are four of these beams in the room here. And they are all going to be typical from a dimensional standpoint.

So let's go ahead and grab our length item. And let us make a new takeoff item here. And we are going to call it 3 inch by 7 and a half, 7 and a half inch glulam.

We'll just leave it at that. We'll just call it glulam beams. And let's just say at the music room roof.

And there are going to be four of these as we can see, 1,2, 3,4. So let's just call it 4, count of 4 we'll say. We're going to keep this under 061100 wood framing in terms of specification section as well. And let's just go ahead and run this takeoff here.

We're going to go from the edge all the way down. And we can see that that comes in at 18 foot 6 and a half inches. And that's great.

We have the length there. We know that we're going to have four of them because there are four showing on the plans. And I do see a note here about cambering these pretty architectural drawings.

So let's just make a note when we're going to purchase these or if we're reviewing a subcontractor bid for this, we can just say include camber. The camber obviously is a kind of bend in the beam to almost like pre-stress it and make it able to hold heavier amounts of load. So that would affect maybe the length of these if there is going to be a camber involved.

Since we're typically going to be ordering something like a glulam beam from a specialty supplier, then we'll just make sure to note that when we go to order them. All right. And that is the kind of main structural components up at the second floor level.
