So you're going to have other elements on part of your facade, and a few tips on other areas, how to measure these. So windows. Okay, so windows are typically measured on a square foot basis. Although one has to bear in mind that the square foot price of small windows is high, and the square foot price of large windows is high. It's because of all the engineering involved there. So it's good to group windows of certain sizes together. Now you'll see later on when we're building the estimate, actually we need the concept stage estimate. It's quite typical just to count up the number windows and your units actually will be per number. So you just count them up rather than square foot basis. The material of the window affects the costs. These are typically wood, aluminum or vinyl. And the glass of the window also affects the cost. So you have insulated glass, triple glazed glass. Also other factors include whether the window is operable or not. Is also affects the cost. It must be in the description that you're recording your quantity of that particular item. Okay, we're now going to look at finishes. So, finishes again, these are usually measured on square foot basis. So we're going to look at floor finishes and wall finishes. So floors you could have anything from carpet, to tile, or to wood floor. To wall finishes, this could be paintings to the wall, as simple as that. It could be tiles in the bathroom or in the kitchens or other coverings, wallpaper coverings to the wall as well. Okay, so we've now got a very simple example of a drawing and measurement for floor finishes. We've got three types here. We've got flooring type one measured at 2,020 square feet, flooring type two measured at 1,389 square feet and flooring type three, 2,281 square feet. It's very important here, you can see we've got three different types of colors. So, you've got organization here, it's clear what you're measuring. When you're actually carrying out the measurement, you measure it from the internal face of the external walls. And you can do that per room basis, or per overall area of that floor type. This is from an on-screen takeoff. You can see it quite clearly and it pulls up your quantities, so there's the error, margin of error, is less so. The manual way would be a scale rule and you'd just mark up your dimension sheets or the document that you're using with the quantities. So, wall finishes again, they're very simple to measure. Wall finishes are captured as square foot within the estimate. They're usually taken as a linear measure, then multiplied by the wall or partition heights. Items such as windows and door openings are deducted from the square foot area if it's a schematic type of estimate or above. But again it depends on the project and the expectation of the level of detail you're going to in the estimate. Also it's worth noting the cost of finishes to reveals, working around the opening negates the saving from the area deduction. Common types of wall finishes. Painting, all types of wallcoverings on all internal partitions. So the way you measure it on plan is first of all linear feet. You then multiply by the floor to ceiling height to get the full square foot area. You've got to remember, there's a few little tricks as you're measuring these items. If you're doing a partition you're more than likely to get the full area and you need to both sides if it's the same material, particularly painting. So the square foot area then is multiplied by two, this is to account for both sides of the partition. Just remember it's not always the case so sometimes you might have one material finish, so you don't do that all the time. So you can see here as an example, again key that you've got different colors. If you're doing it by hand you could use a highlighter and you'd mark up on the drawing as you're measuring the linear foot of the actual partition itself. Again if you're doing it on screen it will automatically put colors on it and a lot a bit of organization there. So we've got here for this particular example we've got partition to one side in one particular wall and we've got partition to two sides on another wall. So first of all we're going to do the partition with both sides. You measure the full length, and for this one it's 96 linear feet. You put that into your thin sheet or into your program and you now need to know the height. So, height should get from the ceiling layout drawings or other details in the specifications or other design documents. Sometimes the architect can be helpful and it can even be on the actual partition drawing itself. So here, the height is 12 linear foot. Now we're doing both sides, so you can see here in the calculations it's 96 linear feet by 12. Linear foot high, by 2. Gives us a calculation of 2,304 square foot. It's that simple. Then we've got a partition that is going to be painted to just one side, so it's just one side again. Again we've done the linear length, it's 37 linear foot by the height of 12 linear foot equals 444 square foot. So your total quantity for this particular take off for painting is now 2,748 square feet, it's that simple. So other common types of wall finishes can be fabric wrapped panels, wall tiles, pantry backsplashes, all part of internal partitions. And these finishes can be expensive and should be measured with greater accuracy. Square foot of finish is usually measured on section when possible. Unlike measuring painting, voids and other areas where there's a break in the finish such as storage units, these are deducted from the square foot area. So here we've got an example with tile backsplash so we're looking at elevations here now. We've been looking at plans before, so we've got elevations. So want we to get the backsplash tile area above the kitchen pantry cabinets. It's a very simple square foot basis. On your onscreen take off you'll literally just go around all the edges and it will give you a full area there of 62 square feet. Again if you're doing it manually by hand with a scale rule, you would really just split the area up there in blue Into different squares and oblongs. Keep it as simple as possible and you'll get to that measurement there of 62 square feet. Just remember the way you record this, the description of it, the location of it is really important as you're doing a measurement. So, measurement recap. Carefully review the full drawing pack including specifications and other associated design information. Clearly and accurately record the measurement description. Check your scale on standard items such as doors. Review and check your work, so you must review your own work, that's very key, you need to make sure you're comfortable with it. And then it would be very good if you can get someone else to review your measurement as well, and do spot checks. It's really important that you go through the drawing pack. Now sometimes you might see a drawing that you think is not relevant to the actual measurement you're doing. But I'll tell you now every single drawing in that pack is really important, and it's there for a reason. You get a lot more information by looking at all the other areas as well such as the structure steel work, design pack and all the other engineering packs. It really does paint a full picture. So examples I just gave you there were architecture items and really by looking at the structural items as well, you'll be gaining a lot more information on the measurement itself.
