MEP coordination method is used for developing 3D coordination models where all Mechanical (HVAC), Electrical and Plumbing components are integrated effectively. This method assists in reducing conflicts among these MEP components. MEP coordination is considered as one of the most vital processes in construction that should be given special attention as it ensures that the building’s architectural design and the structural framework doesn’t interfere with its Mechanical, Electrical, Plumbing, and Fire Protection systems. Thus, it has become one of the most integral practices in the AEC industry. MEP coordination process varies from one firm to another depending on the client’s requirements and the Level of Detail (LOD) sought.
Evaluation of Consultant Design Drawings and Structural/Architectural Plans
In the initial step, the MEP coordination service providing organization gets single -line drawings from the MEP-contractors or consultants. Later, they analyze the structural and architectural plans in depth. Also, they study the MEP specifications apart from the evaluation of drawings, layouts with consistency. In the end, MEP coordination services provider designs a roadmap for coordination.
3D Prototype Formation
To fulfil the need in the initial phase, the MEP coordinator generates an accurate 3D model by applying AutoCAD or Revit. This 3D model demonstrates total MEP services with adherence to the architectural and structural conditions of the building. Besides, this entire model acts as the base for various other important development-related plans, elevations or sections. MEP coordinator employs the 3D model for client inputs as well as generating complete walkthroughs.
Clash Detection
After completing the above step, we evaluate the coordination meticulously for detecting clashes among the MEP components. If we notice any chance of confliction such as design related clashes, workflow clashes or clearance clashes, we instantly fix the errors.
Creation of Coordinated Drawings and Sections
Once the 3D model is tested for horizontal and vertical coordination and clearance, coordinated drawing sets are prepared to show how mechanical, electrical, plumbing and fire-protection systems work together in the same space. Besides, to make sizes clear for each discipline, additional notes may be added. The coordinated drawings form a ready reference for individual service-by-service drawings. In addition to this, firms responsible for handling MEP coordination may take section, elevation and isometric views from the same 3D model and use them to explain to the clients and detail the layouts.
Creation of Detailed Service Drawings
At this stage, each of the single service-by-service drawings is created and details related to their sizes, heights, and distances from gridlines, are added for further clarity. While these drawings are used by site installation teams, they also form the basis for fabrication drawings.
Modifications based on As-Built Changes
The final stage involves modifying the model and the drawings based on any on-site changes or deviations that may have occurred. For instances where the coordination exercise has been executed accurately and the installation has been carried as per the instructions and layouts in the construction drawings, the As-Built (also known as as-fitted and as-installed) drawings are minimal.
