First, a definition of "take off" : The length of pipe to be removed taken off such that a pipe and a fitting make a specific length. The term is a concept shorthand used by pipefitters and plumbers. This is not the same as a material takeoff, which is a list of all materials needed for a project.

Take-offs in general are specific to pipe construction PVC, copper, etc.

How do I calculate the takeoff for a 45 degree elbow joint? Ask Question. Asked 6 years, 11 months ago. Active 3 years, 9 months ago. Viewed 38k times. Wouldn't it depend on the particular fitting being used? Such ratio calculations may give you an approximately useful value, but there are variations between manufacturers, and of course fittings.

I wouldn't trust anything if real accuracy is needed except actually measuring or using the manufacturer's dimension tables. Active Oldest Votes. HerrBag HerrBag Daniel Griscom 5, 11 11 gold badges 25 25 silver badges 38 38 bronze badges. Jalal Pakdaman Jalal Pakdaman 1.

Enter your preferences below and then, use ImproveNet to connect with an experienced fencing contractor near you.

When many of us picture the American Dream, a wood fence is surely in the portrait. Beyond adding that sense of privacy we all want in our home, a new fence, no matter the material, increases the value of your home, deters intruders, keeps pets and children nearby and helps eliminate outside noise. Why you install a fence is easy. How much wood fencing you need is another obstacle all together. Luckily, you've come to the right place. Use our wood fence calculator above to determine exactly how much wood you need for your new fence.

Once you enter all your specs, you'll see how many post, rails and boards are required. Of course, these numbers will go a long way in determining your final wood fence installation cost.

As you can see above, there are a lot of factors at play. To make it as easy as possible to calculate how much lumber you need for your new wood fence, keep the following fencing basics in mind:.

If you're brand new to a wood fence installation, follow the steps below to ensure you buy the correct quantity of all materials:. Preparation: Check with your city so you know exactly where you can and can not install the fence. Also, see if you have to pull permits. Then, call so they can mark your property and utility lines. This ensures you don't cut electricity for the entire block.

Sketch the Fence: Lay out your fence with stakes at each corner and string in between. Then, use a long tape measure to determine your total wood fence length. Number of Posts: As we said earlier, posts should be no longer than 8 feet apart from each other.

Some homeowners go with 16 feet, but if you do, your fence will not be as sturdy. If you go with 8 feet, divide your fence length by 8 to get the total number of posts. Therefore, a foot fence would require 12 posts. Always round down. Therefore, if you're installing a 6-foot fence, make sure your posts are 9 feet high multiplied by 1. If you're installing a 4-foot fence, make sure your posts are 6 feet high.

Once you determine your post height, multiple that by the number of posts to get the total linear feet of post material.This process is known as takeoff — or material takeoff MTO — and is an essential part of the estimating process. For a small one-off job, an experienced builder should be able to estimate the materials required in his or her head. A more thorough process is necessary for major construction projects, however.

It is important to approach the task in a methodical manner in order to achieve the most accurate approximation possible. As well as providing a precise estimate for yourself and your client, this will also help the job run smoother on the ground by ensuring that your workers or contractors have everything they need.

It is worth noting that, while a thorough takeoff will improve your estimate, there will be other factors to take into account. These include your office overhead costs, shifts in market prices for materials, and various other expenses.

What to count. Essentially, the takeoff should quantify all the materials needed to complete the building, structure or project. This does not include assets such as tools and equipment, which are also required to do the job but should include all the physical materials that go into the project. This could be raw materials such as concrete, timber or sand, as well as prefabricated materials; bricks, lengths of electrical cable, plumbing pipes, and light fixtures.

How to Master the Takeoff In Construction Estimating

Looking to improve your estimating skills? In addition to counting the materials, the MTO should also specify the type of material required. This could be the grade of steel or the type of electrical cable, for example. Different contractors might have a diverse range of requirements when it comes to compiling their takeoff. A roofing specialist will use different materials than a concrete contractor, for example, but the principles of takeoff are broadly the same.

There are four key types of measurement required for the takeoff in most construction projects. The estimator will need to count the numbers required for specific individual items. These could be anything from the number of light fixtures required for a given building to the number of studs necessary to finish the project.

Some items, such as cables and pipes, are measured primarily by length. You will also need to know other dimensions, such as diameter, but this information will be included with the type of material required. You might need to allow for extra amounts for elements such as drops for switches, receptacles, and panels when measuring electrical cable. Some materials will require a measurement of the surface area.

This could include elements such as flooring, cladding, or an estimate of the amount of paint needed for a given structure. Measurements of volume may be needed for some materials, such as the amount of asphalt used per yard or the concrete required to lay a foundation.

There are two main types of takeoffs. However, it is crucial that the estimator be able to accurately read blueprints and plans for the type of work being quantified general building plans, electrical and plumbing schematics, etc. As well as diagrammatic representations of the dimensions of the project, these will contain various symbols and notes that may indicate the types of materials required.

Working from these plans, you can use colored pens, pencils, or markers to distinguish the different items and types of material specified. As paper blueprints can be expensive and time-consuming to produce, many estimators are adopting new technology to perform their estimates. You can then transfer the quantities and materials to spreadsheets or use various preprinted forms and worksheets that can help you to work out the exact material costs for each component.The Pipe Calculator is evolving to provide more and more information at your finger tips.

This radius will vary depending on the outside diameter of the tube, the wall thickness, and the angle at which the tube is to be bent. It is important to understand the different elements of a bend in order to make accurate calculations. Using the same variables as above, the standard dimension ratio SDR of a pipe can be calculated thusly:. A simple way to determine the center line radius of a bend of a specific angle is calculate a full circle, then divide that number by to find the measurement of one degree.

Then, use this formula:. For example, if your die creates a 2. The black line represents an offset bend in a tube; the red triangle represents the triangular geometry this offset creates. The relatively simple math formulas of sine, cosine, and tangent can be used to determine the angles of the triangle, and, therefore, the necessary angles of your pipe bend s.

Most scientific calculators and even the calculators built into smart phones have these functions. View information about bending conduit using a bender and the deducts and multipliers charts.
