The construction industry is increasingly using 3D modeling in the design and drafting of various projects. 3D modeling is a technique that enables the creation of digital models of structures and parts of structures where the model can be looked at in 3D. This enhanced visualization has a host of advantages over bidimensional drafting for new constructions in all sectors of the construction industry. So far in this blog post, I will discuss some of the most important benefits of using 3D modeling in construction drafting and designing.
Enhanced Visualization
Another advantage of 3D modeling is the ability to improve the visualization of the project model. Designers and drafters can look in any direction, get a close-up, and even rotate or even explore the design through walking. This helps to build a much more accurate picture of the final physical structure than if one interprets the two-dimensional drawings. The component and system work in context which enhances the integration of architectural, structural & MEP designs. They are also more accurate in 3D and also the likelihood of clash detections is much higher. The advanced visualization thus facilitates the project team to solve problems beforehand when construction is not advanced.
Improved Collaboration
3D modeling software enables the other stakeholders involved in a project to view, rotate, and annotate a centralized model. Cooperating and sharing such a detailed level of information is just hardly achievable with the help of 2D drawings. Project teams can observe the design intent and the work progress, as well as manage and share comments and feedback. Every stakeholder, from the architects to the structural steel detailers to the Millwork Cost Estimator, can therefore work in the same model environment by appending their component designs to the master file. This avoids mistakes and makes for constructability, as well as minimizing change orders that are costly down the road. Therefore, 3D modeling enhances collaboration and communication among different people.
Accurate Quantification and Estimation
A 3D model has highly detailed geometrical information that can be used to obtain correct volumes and create cost estimates. From the model, specialized software can determine lengths, sizes, volumes, and even counts. Take-offs and Structural Steel Detailing can also be automated. In the case of millwork costs, details such as custom cabinets and furniture work can be quoted as per the design modeled. This allows estimators to quickly come up with quantifications without having to use plan sheets and measuring tape. It also allows them to give accurate pricing information at the design stages instead of having to wait for the 2D drawings to be completed.
Supports Construction Planning
3D modeling is useful in planning and enables the contractor to see how construction will progress and what the sequence and method will be before actually moving to the location. This serves as the model for digital fabrication and it can link with building information modeling (BIM) software systems. Contractors can associate schedules with the 3D model to perform phases of the project to plan and make necessary enhancements. It also helps in coordinating with subcontractors regarding construction time and cost. It also enables the project managers to convey physical sequences and transitions to crews in a more precise manner.
Facilitates Future Operations and Maintenance
As for the owner, a 3D model gives a precise reflection of the actual shape and systems for operations, upkeep, and management of the asset once construction is done. It is useful for all facility managers to use the model for spatial coordination, assets management, renovation work, space allocation/utilization analysis, and planning of the emergency response. The model can also be used in the future when an addition or alteration to the building is planned. The above applications show that the value of a 3D model is not limited to the construction phase of the building only.
Conclusion
In conclusion, getting involved with 3D modeling provides numerous benefits over 2D drafting when it comes to the construction business. It enhances visualization, fosters communication between project stakeholders, determines quantities and costs, contributes to construction planning, and assists in facility maintenance. With the advancement in 3D modeling technologies and software construction firms should incorporate these processes effectively in the Designing and Drafting, and detailing processes for their competitive advantage. To this end, the accuracy that has been identified together with the reduction of time and cost, as well as the elimination of mistakes and delays, will shortly become a requirement for the shift from 2D modeling to 3D modeling.
