1. BIM & Quantity Takeoff
BIM stands for Building Information modeling. Here we are discussing about this modeling oriented
estimating solution which is not a fashionable word for a business now-a-days; rather it becomes the
essential part for a business. As the modeling part is essential for starting a construction, modeling
oriented estimating solution is so important for handling a construction business. And Quantity Takeoff is
that software which performs the above mentioned functions automatically.
About Quantity takeoff
General Contractors, Subcontractors, Cost Consultants, and Quantity Surveyors often done their
job perfectly with the help of the software named Quantity takeoff. They utilize it actively as part
of the construction process. They use it for counting the number of items associated with a
particular construction project, determining the associated materials and labor costs, and
formulating a bid (or estimate) as part of the bidding process. Quantity takeoff is also applied to
the pricing process.
This specific software provides a solution that generates a set of takeoff elements like counts,
measurements, conditions that effect cost. Using this software an estimator is able to do his job
more quickly and more accurately perform for bidding or pricing.
This can be used for various purposes - initial pricing, bidding, cost impact of changes made to
the model etc.
BIM oriented estimating solution can produce the quantity takeoff automatically
BIM oriented estimating solution provides the estimators a unified platform for easily reviewing a BIM
model in both 2D and 3D view. BIM oriented estimating solution can produce the quantity takeoff
automatically based on the calculation criteria set by the estimator. At the same time it has the ability to
further take off the quantities into estimating assemblies and items, with a breakdown of construction
materials, equipment, and subcontractor costs.
True BIM estimating software helpful for Contractors:
Contractors do not have to face a hurdle or complexity at the field of their job when they perform with the
help of BIM estimating software. This is truly helpful for performing the design quantity information and
item cost databases just perfectly.
As the true BIM estimating software has the capability to keep hold of the connections between design,
quantity, cost items, and scheduling activities contractors face the facility to do all these jobs cleverly &
smartly even before the scheduled time.
BIM oriented estimating solution helpful for Construction planning.

2. Any change in design or resource can be reflected in the estimate and schedule. Any kind of estimation is
basically submitted according to the design or model of the construction. Sofor doing estimation just
perfectly we can use BIM oriented estimating solution. When such a BIM system is used in pre-
construction, it helps all project stakeholders increase productivity. The perfect performance of BIM
oriented estimating solution makes an analysis in constructed form. It almost improves the budgetary
decision making and speeds up the construction planning.
With BIM, the quantity take-off can be greatly speeded up
With BIM based visual estimating the quantity take-off can be greatly speeded up. As the model gets the
information about all the objects in the building as well as their dimensions the Quantity Take off can
easily produce necessary information within a very short period. However, it is must be noticeable that it
will, by itself, not enable automatic take-off. This is because the estimating process is a lot more
complicated than simply getting a list of objects and their sizes.
BIM also involves analyzing the building design, grouping objects into appropriate assemblies for
construction, setting assembly and item variables, and then pricing the objects by taking off these
assemblies or items.
The assembly takeoff remains still a substantial process in cost estimating unless the BIM model was
developed to some extend that the objects are derived directly from construction assemblies. Currently,
however, BIM applications do not model construction assembly details, for example, the nails, studs,
drywalls, etc. for a wall object.
Facilities of uses of QTO
To perform any size estimate and for checking a BIM model for precision QTO can be organized. Data is
transferred to any of the project management, or estimating systems, or amount produced as an Excel
“spread sheet” file. QTO will also receive component information from cost analysis services for instance
RS Means.
From the above discussed portion we can get a conclusion that QTO & BIM is a great combination which
fulfills the discussed criteria very easily. And Contactors can take deep breathe just depending on the
combination. Along with this we can get a perfect work benefits & make our time more valuable.
