BIM and its benefits for Quantity Takeoff


In today’s economic scenario, the construction companies must maintain a constant eye on the bottom line. With the number of project bids increasing to rarely seen levels and profits becoming increasingly elusive, robust cost controls are more important than ever. As a result, basic square foot take-offs and unit costs are becoming a thing of the past. For BIM-enabled Contractors and Construction Managers, their appetite for automated BIM-based estimating from highly detailed models continues to grow rapidly.

In this age of cut throat competition, by using an automated and efficient estimating process we can easily iterate through more alternatives to find value. With more details in the estimate, there are simply more places for us to look for savings. After we win the work, we react to changes in the estimate in a precise and automated fashion and avoid losses related to incomplete change orders. We envision the estimator becoming a cost analyst limiting the tedious task of quantity take-offs.

The use of BIM software like Revit and Tekla in our preconstruction department allows us to leverage relationships with AEC firms to better ‘build’ the model while streamlining our estimating efforts thus adding more value in the preconstruction phase of the project.

How it Works
The information rich Tekla and Revit structures Building Information Modeling to find out the cist database and other relevant information for the project. One of our goals has always been to transfer as much intelligent BIM design data as possible to downstream applications such as estimating and scheduling. Streamlining this process continues with the connection of the model to the estimate. Projects change and so do quantity take-offs and estimates. This process allows users to see changes in the model visually and automatically change the project estimate accordingly bringing a high degree of efficiency to the change order process. While one benefit is the dramatic increase of the efficiency in producing construction quantities and plans, the various new BIM-based estimating features such as visual what-if cost analysis, automatic quantity and cost update for a design change, as well as side-by-side comparison of construction quantities and cost, really help cost estimators produce better estimates in a better and faster way.

Basic square foot take-offs and unit costs just don’t cut it any longer. The users must have the ability to quickly obtain accurate project quantities, apply costs to them and react to changes. Further, the customers are seeking take-off and estimate granularity this is either impossible or extremely difficult using traditional 2D project information or traditional digitizing. This integration meets this need and working with Innovaya helps our customers become more efficient and effective.

Conclusion:
The Building Information Modeling is the most efficient way to pull out useful information for quantity takeoff. All the things like; winning the bid, completion of the project with success depend on the BIM. The accurate, dynamic and data rich 3 dimensional models can create new business opportunities. The BIM users can streamline the design, fabrication and construction processes in the specialized areas like; construction companies, structural engineers, steel detailers and fabricators, concrete detailers and manufacturers.

Summary:
Building Information Modeling is an exclusive process to expand the business opportunity via quantity takeoff. With the relevant information from BIM winning the bid, estimating the project and completing it within schedule time frame and budget make possible.
