Calculating the value of quantity takeoff services for the building industry varies
according to project conditions and company experience. As a professional in
the building industry, anybody might come closer to this term. This term is in
the industry for a long time and is an important part of the industry. Quantity
takeoffs are determined by quantity surveyor services. A person may end up
making or breaking the project in this step. Furthermore, it can underestimate
or overestimate the project cost. You need highly professional skills to
calculate the quantity takeoff. Building companies define Quantity
takeoffs with associated terms. It includes estimation services, material
takeoff services, and quantity takeoffs. The key to completing any
project lies in determining realistic cost values with accuracy using quantity
takeoff. Different quantity surveyors use methods and terminologies according to experience for quantity takeoffs.
In this article, you will get guidance on correct and accurate quantity takeoff terminologies
and methods. Furthermore, you can do this by using different techniques according to industry requirements.
What is Quantity Takeoff Services?
Some dictionaries define quantity takeoff services as the estimation of quantities
for the project from documents such as plans and drawings. Certainly, it is recorded in the bills of material for the project.
In practice, the building industry uses quantity takeoff services to describe the
process of estimation. This process includes a review of a set of plans during
pre-construction to “take off ” measurements from plans. Measurements are then
used for forecasting costs. Architectural drawings, engineering drawings, and other models provide a list of items.
Moreover, quantity takeoff services are common in the industry. Anybody can experience
some confusion over its use. For example, you may assume that it is only a cost
estimate for the bills of material. You may also refer to this to forecasting material quantities from plans. But it includes both labor and material.
Interchangeable names associated with quantity takeoffs are also used. They refer to different
things. These terms include material takeoff, construction takeoff, material estimate, and material count. Everybody must distinguish different terms to avoid misunderstanding.
How to do quantity takeoffs
This process is essential for estimating. The quantity surveyor or the builder
should be able to estimate materials. Moreover, you should methodically
approach this process. Various other expenses such as overheads, shifts, and
market costs should also be considered. Everybody should count all physical
materials except tools and equipment in this process. For example, a person may
use concrete, electrical cables, lights, bricks, etc. Quantity and type both should be indicated in quantity takeoff services.
You should focus on counting numbers for specific individual items. Certainly, this will
include numbers and product types. Different items require different measurements
and units. Flooring and roofing will require measurement of surface area as
as well as the quantity required. Finally, some materials require volume measurements to accurately estimate them.
Things to Look for in Quantity Takeoff Services
For calculating the quantity takeoff, you put some information related to the
project. Professionals use mathematical equations and resolve numbers. Then you
ultimately arrive at a figure which is an estimate. Quantity surveyor services should ponder over these points to perform the task accurately:
Unit: You should make sure that the units used for measurements are also used In markets. This will ease the procedure to acquire resources.
Weight: The weight of the material should be calculated to determine the costs to handle them.
Length: Actual and estimated length should be proper and in appropriate units.
Surface and volume: A person must distinguish between surface and volume as the design move from 2D to 3D. Length*width*height is the correct formula for volume.
Methods to Calculate the Value of Quantity Takeoff Services
There are two most used methods for calculating the surveyor quantity takeoff. Technology
is the main difference between these two methods. Building Information Modeling
(BIM) raised the technological bar with complicated systems and tools. Professionals
have reduced excessive usage of materials and issues such as low productivity
by using computer-aided designs. Certainly, digitalization has improved the
estimation and takeoff procedure. But human operators and interpreters are also
important in this method. Therefore, professionals use two methods for quantity takeoff services.
i. Manual Takeoffs
This is used to calculate takeoff manually. Physical plans as well as blueprints for
accurately detailing and describing the material. Human error and time
consumption are disadvantages of this system. Skill and experience of estimator matter in determining the costs. Attention to detail and practical knowledge help in this method.
ii. Digital Takeoffs
In this method, digital tools and computerization are used. This is relatively
new in the industry. It was first devised in the 80s and 90s. You can form
Computerized building models. Large and complex projects are integrated and
digital takeoffs are obtained. This method is superior to manual methods, especially for large and complex projects.
Quantity takeoffs can be complex but it should use methods appropriately to solve them. Anybody should have only a single purpose-accuracy. Manual takeoff is far better than digital if you have an accurate estimate.
Conclusion
Quantity takeoff services are an important and complicated process. Experienced and
knowledgeable engineers can produce accurate data so they can manage a project.
This will help us avoid estimation worries. You need professional quantity
surveyor services to determine accurate costs. Surveyors offer services to
small as well as large and complex projects with years of experience. This increases quantity takeoffs for increasing bidding accuracy and work efficiency.
Quantity takeoff services are important in the building industry. For a successful bid
to best resources and cost management, all involve accurate estimates. There
are some inaccuracies in both methods but the user should know in and out of
the process to get the best results. Digital surveyor quantity services can
help to minimize errors but at the cost of knowledge to use them and trained staff.
Certainly, everybody recommends using digital methods to solve complex
problems. Furthermore, large companies are already getting benefits from computerization and technology.
