nce the stage of concept designing is completed, then comes the essential phase of building execution. When a project manages to reach this level, no amount of re-drawings and mistakes can be affordable. Not just mistakes can increase the cost but waste precious time as well. Considering how these two are taken as irreplaceable resources, you must make sure that the wastage of them is not just reduced but is quite negligible as possible.

So, how can you achieve that level? Sure, the stage of execution comprises the direction of Mechanical Electrical and Plumbing MEP Shop drawings. Also known as MEDP drawings, they can contribute greatly to waste of time and money, if not approached attentively. In such a scenario, outsourcing MEP BIM services can turn out to be an advantageous choice for both stakeholders and designers. After all, it provides virtual insight into the entire project. 

So, now the question arises, how BIM 3D can be super beneficial to MEP contractors? Scroll down and know more about it.

What Is Included in MEP BIM Services?

Most of the times, problems can be discovered in the designs of a plumbing wall, ceilings, architect, and electrical design. To neglect such problems, the role of BIM services for MEP can be considered crucial. There is a variety of services that come under BIM for MEP, such as:

  • MEP 2D layouts
  • MEP shop drawings
  • MEP 3D modeling
  • MEP quantity take-offs
  • MEP clash detection

MEP 2D layouts further comprise:

  • Mechanical services:
  • Heating and cooling system layout
  • HVAC duct layout
  • Fire protection system layout
  • HVAC pipe layout
  • Electrical services:
  • Electrical distribution layouts
  • Electrical wiring diagrams
  • Electrical panel diagrams
  • Lighting circuits
  • Plumbing services:
  • Domestic water system layout
  • Drainage water layout
  • Shop drawings
  • Water distribution plans and diagrams

Whether it is a residential building, leisure sector, or a commercial building, the virtual 3D presentation of mechanical, electrical, and plumbing drawings is quite mandatory. With such models, one can figure out the exact components location in the entire structure. It proves out to be advantageous in discovering the system clashes as well. In return, it can avoid problems and save money as well as time for your company.

MEP Shop Drawings:

With these drawings, you can enable the simplification of the installation process of prefabricated elements, like cabinets, structural steel, trusses, windows, elevators, and more. It focuses more on the process of installation and less on the construction part. 

MEP Clash Detection:

Clash detection is one of the most integral and vital parts of BIM. In a BIM 3D model, these models are generated on individual levels, and its commencement point is the model of design offered by the architect. After this, architectural drawings electrical, mechanical and plumbing shop drawings and site layouts are prepared.

However, these drawings are created independently. Therefore, when everything is completed and compiled, spring clashes in the drawings are bound to erupt. Also, these clashes become necessary to solve. They can be in different parameters. They can also occur in 4th dimension or model spaces, such as during the time of execution.

Once these clashes are solved, they can lead to more work efficiency, quick time schedules, and lesser costs. Thus, clash detection drawings help discover them virtually and safeguard losses before the beginning of construction. 

MEP Quantity Take-Offs:

With these drawings, one can figure out the precise material quantity required for the project. It is the responsibility of every estimator to develop a system of quantity takeoff to make sure that the quantity is not calculated twice or omitted. With this method, you can also calculate the waste level percentage if that might occur on-site during the phase of construction. 

The quantity of material take-off is quite essential for estimating the cost as it generally establishes the quantity and measuring unit for the contractor’s equipment and labor cost. Basically, there would be two different perspectives on why the quantity take-offs are essential. 

If you believe contractors, it is important because it helps with:

  • Subcontractor’s payments
  • Preparation of invoices of the completed work
  • Project scheduling
  • Identifying the required resources

As per the owners, it is necessary for:

  • The initial calculation of the project cost
  • Preparing the BOQs
  • Estimating the completed work to issue the payment of contractors


All of these parameters mentioned above are important for BIM services for MEP contractors which can provide them benefits in several ways. To sum everything up, it can be concluded that when a model is created virtually to comprehend physical challenges, occurred during the time of building construction; there are several issues that are generally eliminated.

This issue elimination in regards to Mechanical, Electrical and Plumbing drawings turn to be a boon for projects as it assists in the completion without any delayed time schedules and extra cost. In turn, it also increases efficiency and productivity in a better way.
