BIM software provides benefits for calculating quantities and determining construction costs. It allows for accurate and efficient quantification during design and execution. Quantities can be automatically calculated from 3D models in minutes versus manual calculations in Excel. Any model changes are immediately reflected in quantity takeoffs and cost estimates, reducing disputes. BIM helps manage material ordering and inventory through precise quantification of needs. Its use promotes accuracy in project quantities, costs, and overall project lifecycle.

1. What are the benefits of BIM software in calculating quantities
and determining the cost of projects?
It is common knowledge that the quantification process plays an important role during the
project life cycle, from project design to project execution
To be delivered to the owner, and has a significant role in determining the time, cost and
quality standards of the project requirements.
During the study and audit of the project:
Starting with the calculation of estimated quantities (BOQ), through which project costs are
estimated,
The design team calculates the quantities of the drawings from the AutoCAD software, and
then writes the results to Excel, but it takes time to finish them, not only a few, especially in
large and unique projects, and it is also possible to calculate the quantities, regardless of
how well he can write and write some results Incorrectly.
Including Revit:
Where the study of modeling and the calculation of quantities
Its advantages in calculating quantities:
- The ease of visual verification in terms of reference to a particular element, and know the
quantity accurately
- Adjustments are made directly to the bill of quantities when the model changes, such as
changing sections or materials
But in addition to the previous features NAVISWORKS software came to give us the best
features, including:
- With the click of a button the project quantities will be fully calculated according to the
classification of the items, all of which takes only a few minutes, and is one of the most
important features of the software

2. - It is possible to make lists of materials, labor and equipment when analyzing prices, and
find out their impact on the cost of any item, which helps us to discuss different alternatives
with the owner from an economic point of view.
- Bills can also be exported to Excel for formatting reports.
During the executing of the project:
In large projects, there are specialists to calculate quantities in each engineering field to
follow up the accounting of subcontractors.
There are also accountants of quantities to deal with the supervising entity according to the
items of the BOQ's estimated disclosure, the accounts may be inaccurate and the project
manager may request materials that are premature or redundant due to lack of accuracy in
the quantity calculation.

3. All this will carry the main contractor the burden of financial expenses are not a few
adversely affect the progress of the project. It is also possible that the quantities issued by
the supervisor are different from the quantities of the main contractor, resulting in ongoing
disputes between the parties
The benefit was from NAVISWORKS
• Any modification during the implementation of the project at the request of the owner, we
will modify the models, which is reflected on the BOQ and become directly modified, and we
export to Excel for coordination in order to approve the financial statements of
subcontractors and the claim of the owner.
• The benefits reflected on the supervisor are to raise the financial statements of the main
contractor, based on the quantities resulting from the modified models, agreed upon by the
parties. This will reduce disputes and accelerate the work of the project.
We can find a precise organization of the material supply chain, by taking advantage of the
software in determining when to store materials, and when we can order new materials
from suppliers.
We conclude the article:
Today we have become an urgent need to spread the culture of BIM and its applications,
and to do the work of Arab research to study the benefits when used in projects through
most important of which is the effective and positive impact of the accuracy of project
quantities on the life cycle of the project.
