Every contractor has the task of finding out the quantities and types of material needed for the construction. This is vital in the estimation of the material; hence you can always find out the cost of the construction. This process of estimation is known as takeoff. There are two types of construction takeoff that you need to learn about before mastering the techniques. These are the digital and manual take offs.
Digital Take Off
This is a process where the companies rely on software and digital blueprints for their estimations. The software is developed to aid in streamlining and partially automating the process of take off. Even though the software specifications always vary, you will always get to analyze and enter the measurements and quantities in the digital format. They have also been integrated into quotation or binding programs that can use two processes.
Manual Take Off
Unlike the digital take off, the manual take-off uses the traditional blueprints and plans to carry out accurate takeoff. This process demands that the estimator must read the blueprints accurately for all the work being quantified. The process may be kind of tiresome as you need to transfer the quantities and materials to the spreadsheets.
Once you have known about the types of taking offs, then here are some of the methods to master construction take off.
#1. Breaking down the Process
You need to master how you will break down every process to suit your workflow. You should expect variance on the number of factors like types of drawings, software used, and scale of job among others. Here are some ways to break down the key manual take-off process;
Calculating the Takeoff
Once you have the measurements and counts ready, you will need to use them in producing the takeoff figure. You should then deploy the trade market values in estimating the accurate material cost.
Counting the Symbols
You need to master this as it will aid in identifying the number of components needed for finishing the task. Each component type needs to be counted individually to ensure accuracy.
Measuring the Circuits
This is for the electrical contractors. You should measure all the circuits in the drawings by checking out the scale used on the page. For accurate measurements, you will need to use tools like scaled measuring tapes, electronic measuring wheels, and architectural ruler among others.
#2. What to Count
It is also vital that every contractor fully masters what is needed to be counted at the construction site. The takeoff needs to easily quantify materials that will finish the structure or building. The count should not comprise of things like equipment and tools but only raw materials. Here are the main measurements that you will need for the takeoff.
– You need to measure the volume of material like asphalt that you will require per yard.
– Elements such as flooring and cladding need to be measured to find the total surface area. You may also estimate the amount of paint needed.
– When used materials like pipes and cables, you have to measure the length and other dimensions like diameter.
– You also need to count the number of materials required for every project. For example, the number of bricks, pipes, and roofing materials among others needed for every project.
These are some of the simple ways to master the construction take offs. Depending on the project you are working on, you will always need to master these simple ways to get the ideal estimate for the material needed for the construction.
