MEP BIM Services – An introduction
“Better late than ever” is an apt saying in today’s construction scenario. There are so many newer technologies and software that simplify the construction process to our advantage. If we do not use BIM Services today, we will miss the bus forever. We will try and understand the MEP BIM segment today. As we know, there are total 4 disciplines in the Virtual Construction Modeling domain, Architectural, Structural and MEP Modeling. Today we will discuss the most complex and critical part of the Building Information Modeling arena that is MEP BIM Services.
MEP BIM Modeling Services are more complex and critical of all the other services. This segment is the final part of the entire pre-construction process. Only once we complete the modeling part of MEP we can proceed ahead with the BIM coordination process, 3D/2D coordinated shop drawings etc. Achieving 3D spatial coordination through BIM with a larger level of accuracy and collaboration is extremely critical and important for a seamless construction process. Apart from 3D geometry through BIM we can also extract and work with complete building data across all construction stages. Collectively MEP BIM Services consists of
1. MEP BIM Modeling: We create a detailed and accurate 3D model with all MEP components modeled based on specific dimensions and requirements. It collectively consists of HVAC Modeling, Electrical, Plumbing and Fire protection modeling. These models can be used for Interference check and BIM coordination purposes. We can also plan a complete 4D Construction Sequencing with the help of a complete MEP Model. Using BIM for automated design have increased over a period of time.
2. Clash detection and Interference check: This is the most critical phase of Building Information Modeling. This justifies the purpose of BIM’s existence in the construction industry. We can perform interference checks and detect clashes that can hamper onsite construction. With the help of Revit and Navisworks, we can extract a clash report and check the constructability parameters. Large service clashes, interdisciplinary clashes etc. can be resolved in the virtual modeling phase. By the time the actual construction starts, we would have resolved the majority of the clashes and interferences.
3. BIM Coordination Services: Post interference checks the clash report is extracted and shared with all the parties involved in construction through a collaborative meeting. This meeting helps in resolving the clashes and create a final coordinated 3D BIM Model that can be used for construction. This coordinated model further helps in 4D construction sequencing, extraction of MEP shop drawings etc.
4. MEP shop Drawing Services: After completing the Modeling and BIM Coordination process, we can extract MEP shop drawings or MEP installation drawings. These drawings basically provide a general arrangement layout that indicates where and with what detailing the MEP components needs to be installed. Also further, we can work on creating Fabrication Drawings with sections, elevation drawings, parts, assemblies etc. With the help of Revit, we can create a detailed 3d model and extract shop drawings from the model. Any changes or last-minute modifications is easy to handle with the help of Building Information Modeling as any change made in the 3D model reflects automatically in the 2D Drawings.
Conclusion:
This was an overview of the services any company offers under the “MEP BIM Services” flagship. Revit, Navisworks etc. are software that is used for 3D Modeling as well as BIM Coordination. Looking at the current trend, it is evident that future developments will be much more automated and shall further improve construction productivity.
