Final Steps in Exterior Takeoff for Siding, Railings, and Standing Seam Metal Roofing Installation

Completing Detailed Exterior Takeoffs for Siding, Railings, and Metal Roofing with Precision and Accuracy

Discover the comprehensive process of measuring and estimating for siding, roofing, and railings in construction projects. In-depth instructions cover everything from taking off areas, understanding details and extents, zooming in for critical corners, to determining accuracy which is a critical component in performing these estimates.

Key Insights

  • In construction estimating, a thorough takeoff of areas, especially for siding and roofing, is necessary. This involves tracing the outlines, zooming in for critical corners, and ensuring accuracy for a precise estimate.
  • Understanding the details and extents of the project is fundamental. It's crucial to examine the cut-through detail and other specifications to understand precisely what materials and structures will be involved, which directly informs the pricing.
  • The accuracy in performing these estimates determines the possible profitability of the job and the margins that could be gained. Therefore, precision in tracing, zooming in at critical corners, and understanding the details is integral to a successful job estimate.

We have completed most of our siding. We still have the final elevation of the music room to do, so let's go ahead and knock that out right now. Let's go ahead and grab our area takeoff again, and we're just going to have to trace these few doors, and that will be the rest of our siding here.

Let's first look at the cut through detail, just to really understand the extents. It looks like we've got this overhang, but that's not going to get in the way of the siding. That is still going to be right here.

Okay, we are going to go back to our elevation, and let's go ahead and finish this takeoff. Start off in the corner with the siding, and trace it over to this door, and then start to go up and around these doors with these fixed lights at the top. The way that I like to do something like this is really utilize that wheel on the mouse to zoom out to be able to do some of these longer runs, and then really zoom in at some of the more critical corners where there's a lot of lines that could muddy the waters a bit, to really make sure that you're getting that accuracy.

Then again, use that wheel to zoom out, get some of these longer runs here, and then zoom in and go ahead and make sure that you've got the correct line that you are snapping to. It is very critical to be precise when performing these estimates. You know, these are going to inform the pricing that you're putting forward, and it really is going to perform, really going to determine how much money you can make on the job, and what your margins are going to be.

All right, so we'll run this siding over to the corner here, and we'll run it underneath this little roof here, and we'll just run it straight across, and then back down. All right, there we go. So that is our composite siding.

Just take a quick look, make sure we look like we've gotten everything pretty accurate, and I think we have. Good, so we've done the west elevation. We have done our south elevation.

Let's go ahead and look at the east elevation. We've got that. Okay, so that is the completion of our siding takeoff, and there's still some exterior railings, so let's go ahead and knock those out.

This is going to be a length takeoff, so let's choose our length item, and I've already got exterior metal railings here, but let's go ahead and make ourselves one. Exterior metal railings. All right, you can give that a color.

I like giving it this kind of purplish color here, and then I don't want to put any sort of lines or anything on there, so let's take those off, and then for specification section, this will be 055200 for metal railings. All right, so let's just go ahead and grab these linears here, so starting at one end of the railing to the other, and that's going to be easy. Let's go ahead and turn this caption off.

We'll use this box to check and uncheck. I personally don't like when the lengths are on there, so we've got that. While we're here, I did notice a little imperfection here on the corner.

Let's go ahead and put that back. All right, great, so we've got this railing here. Let's go ahead and set this as our default, and then let's go ahead over to the west elevation where we've got this long run of railing as well, and since we set that as our default, the next time we choose a length takeoff, it is going to bring us to exterior metal railings, and we're just going to take this railing all the way over across this whole balcony.

Perfect. Let's double check anything else. We don't have any railings over here.

We've gotten the railing down here. Go back into thumbnails and go over to sheet 12. No railings in our scope over here as well.

So that is our exterior metal railings, and you know what? Next up, let's go ahead and do this standing seam metal just because we are on the exterior, and we can go ahead and get this all finished off. So let's look at where else we have it. On the west elevation here, we've got it on the top and the bottom.

Let's review these notes, number 12 and number 5. Number 12, metal roof fascia panel similar to the metal roof, and number 5 is the metal finish continuous across the bottom of the open span. Okay, let's wrap our heads around this a bit more. We'll look at sheet 10 to see our cut-through.

So up at the top, we see we've got standing seam metal roof, and then underneath that is note number 3 here. We've got roof framing for structural, and then number 8, we've got a curved beam with a radius. Okay, down at the bottom, we have detail 6 and detail 5,2x6 composite siding.

Alright, that's going to be for the wood siding underneath, and then number 5 is going to be a galvanized sheet metal wrap. Okay, so let's just start with the standing seam metal roof. That's going to be the whole roof, and it is going to be on top of this overhang as well.

So let's look at this detail D7.4. D7.4, detail number 4. Okay, great, eave detail, metal roofing. So the metal roofing runs continuous until it gets to the face of this eave, and then it looks like there is a bit of a fascia panel and an angle flashing here. We're not going to get into the extreme detail each of these pieces and parts here with all these angle flashings, but this gives us a really good idea of how this is constructed.

Now let's go ahead and do this standing seam metal takeoff here. We can go ahead and create a takeoff item. So it's going to be an area, and we're going to have a few of them.

So let's go to our tool chest. Let's go ahead and select the last area takeoff and duplicate it, and then let's go ahead and change the properties on this one. This is going to be standing seam metal roof, so we're going to call it standing seam metal roof, and let's go ahead and change the color on this one.

Let's make this orange, we'll say. Go ahead and make that orange, and for the specification section here, this is going to be an 076100 sheet metal roofing. So this is going to be our standing seam down to this kind of fascia angle piece here.

So let's grab the standing seam metal just to these lines, and we'll pull it all the way over here to match up with this edge, and then we can go ahead and run it back over here. That's going to be our standing seam metal. This looks like it's pretty accurate here.

Might have to slide it up a little bit. There we go, great. That's going to be our standing seam.

We'll come back later for these fascia pieces as they may be slightly different. Then let's go to the other elevation here, and take off the rest of our standing seam. Let's take a look at the detail page again just to see what the back side of this roof looks like.

Looks like there is just a bit of an overlap onto the siding. So let's go back there, and let's make sure that we see that. Okay, great.

So this is our standing seam, as well as this. We're going to count this in here too. Let's go ahead and grab our area takeoff here.

I'm sorry, let's go into our tool chest, and then let's get our standing seam metal roof. We'll start up at this corner, and we will just run this all the way down here, and up, and back to where we started for our standing seam metal. Go ahead and hit escape to change our cursor, and let's just do one more look back at our detail just to confirm that we got that totally right.

We've got the standing seam. Now there isn't particularly a detail here, or a specific fascia piece, so it looks like the roof just comes down and overhangs. Then let's go over to this side again, look at this detail once more just to really confirm that we're being accurate.

Got the standing seam metal that comes down. Fascia panel angle flashing. Actually, you know what? This all does appear to be the same standing seam metal assembly, so let's just go ahead and alter that first takeoff.

We originally left this area out, thinking it was going to be a different kind of piece of metal, but it's not. It appears to be the same roofing assembly, so let's grab our tool chest, and let's go ahead and drag this all the way out, and we'll snap it here. Let's go ahead and connect to our other takeoff.

Go ahead and run this all the way out, and then connect back down here. We've added that additional section of standing seam metal, and actually let's pull it all the way down too, so that we are aligned with our composite siding as well. That way we've got this whole exterior covered, and we'll make sure that these angles all line up here.

Slide that in just a little bit. All right, perfect. So that is our standing seam on the exterior here, and let's just go back and give it a quick double check, make sure that we're accurate.

All right, great. We've got the standing seam there, and let's go ahead and finish out some of these other metal panels here. So back into our detail.

On the bottom side, we have this detail 5 and detail 5, and that detail 5 again represents a 24-gauge galvanized sheet metal wrapped under the bottom side to the vented control joint. So let's go ahead and just make another quick takeoff for that. Let's jump into our tool chest here.

Let's go ahead and click into this one, and then duplicate it, and we'll just call this 24-gauge galvanized sheet metal. We'll go ahead into properties here, call this 24-gauge gal sheet metal, and we'll just call this a flashing it looks like, and we'll keep it under this 07-6100 sheet metal roofing, and you can just make it a slightly different orange color. Then we'll go back into our plans here.

Go over to our detail. Let's just go ahead and take all of this off as our flashing. Pull it over to the corner here.

Make sure that we're being comprehensive. Okay, we've got that, and then let's go to the other side and make sure we've got our final panel down here, and then we will be complete with this part of the exterior. Still have a bit of roofing to do, but this is getting this completed.

Excellent. Let's hit escape to take that takeoff away, and let's just go ahead and do a quick visual here to make sure that we've gotten everything. We can see that our music room looks to be comprehensive.

We can see that our stucco looks good. Double check these notes, number one, two, and six here. One is just that stucco, two is the stucco over CMU, six is going to be a crawlspace vent.

That's just something we could add after the fact. Coming back to the south elevation here, we've got our stucco, we've got our railings, we've got our siding. Remember we counted our windows and doors already, so we don't need to double count any of those.

And then back up, we've got our stucco, our siding, all of our standing seam metal panels, as well as our railing. Excellent. Let's go ahead and save this work, and that is going to be our exterior work for the time being.
