What is the importance of model based Rebar Detailing?
Rebar Detailing is the process of creating shop or fabrication drawings of steel reinforcement for construction. They include all the details and specifications about steel connections, welds, lap slices, erection sequences etc. Considering the fact that the strength and resilience of a building is greatly dependent upon its structure, accurate Rebar Detailing Services are of paramount importance.
Using traditional methods like 2D Drawings in order to design reinforced concrete structures is a process fraught with challenges. It is not always very accurate, is extremely time consuming and also has a knock on effect of increased project time and cost. The model based approach helps overcome the challenges as well as provides some significant advantages.
1. Spot small design errors:
The visual nature of the 3D model ensures that all reinforcements are displayed in full geometries. It means any small errors like even a typo can be easily spotted and marked. Moreover, in the 3D model different types of bars or columns are distinctly marked in different colors again making it easy to spot any errors. Over the course of the design process it is also possible that the rebar design clashes with the neighboring elements. Since all the reinforcements are shown in a single 3D model it is possible to detect any clashes with the neighboring elements and figure out viable solutions. If these design errors are spotted in the preconstruction stage and rectified before prefabrication and onsite construction then it could provide various cost, time and monetary advantages
2. Scheduling and Cost Estimations:
With the model based approach it is possible to link time and cost related information with the intelligent 3D model to streamline the onsite construction. With proper scheduling it is possible to spot any workflow conflicts like the date of delivery of components is scheduled after the date of installation. Any time related conflicts are important to spot because it could have a cascading effect and disrupt the whole project timeline. Similarly, in rebar estimations cost is associated with quantities. Any change in the quantities of materials will be automatically reflected in terms of the cost. Thus, with the 3D model it is possible to keep track of cost and time related data throughout the project.
3. Precise Shop Drawings:
Shop Drawings are essential as they provide all the details that would be needed by the manufacturers for prefabrication of steel components like its dimensions, material specifications etc. They are also used by the ground workers to assemble and install these components onsite. Finally, they can also be utilized in order to account for parts especially for large components. It is possible to extract accurate shop drawings from the error free 3D model which increases its precision. Moreover, with the 3D design tools is possible to make modifications as they need to be done on the model individually and not in each drawing separately.
Thus, we can state the using the model based approach for rebar detail increases productivity, reduces errors and provides advantages at every stage of the project from planning and designing to onsite construction.
