BIM has transformed the construction industry and the way it used to deal with complex projects. It started with creating 3D virtual model shifting its focus to BIM 4D Modeling Services and 5D BIM Services cost planning for construction firms.

Quantity takeoffs are an essential aspect of the Construction estimating Services in the construction project. It can be used in small, medium, and large projects to determine cost estimation by all the construction trades. It depicts the list of material to be used in a project. The estimator defines the amount of material required and its associated costs.

To get the cost estimates of material, the estimator needs to get accurate and proper drawings, models, or blueprint. The information processed by the quantity takeoffs has collaborated with the estimation of labor costs, overhead costs, etc.

Types of Quantity Takeoffs

Quantity takeoffs are prepared by many people involved in, and it needs to be unique. Every individual that define quantity takeoffs may have different methods and can format the final quantity of cost analysis.

Manual Quantity Takeoffs

Manual quantity takeoff is determined without any assistance of digital takeoff software. It is entirely prepared by hands, and the estimator would work on physical drawings to create a list of materials. Even today the information is stored by hand in quantity takeoffs being accessed in digital software. Calculation by hand would be more complexes than doing on software.

Digital Quantity Takeoffs

Digital Quantity Takeoffs are prepared on BIM software like Revit that contains digital capability. For easy calculation of material procurement in quantity takeoffs, running it in construction estimating software can be used. Drawings are uploaded or scanned into the program which analyzes the drawings and generates a list of material required in it.

Adjustment and wastage analysis of material and to order materials can be easily done in the digital software, which reduces errors associated with quantity takeoffs. It needs much less time to get produced than manual quantity takeoffs.

Conclusion

Quantity takeoff, when done with BIM software like Revit, calculates material procurement much faster, easier, and saves times. Digital quantity takeoff makes the model calculation of cost estimating services accurate and precise that helps the General Contractors, Subcontractors, and other construction traders to make a decision accordingly.
