MEP Coordination – An Introduction

3D MEP coordination, also known as 3D M&E coordination, is a key element of MEP design concerned with spatial configuration and the layout of building services trades (HVAC, pipe work, public health and electrical systems).

What does a harmonious orchestra and the construction process have in common? Both require the precise integrated efforts of a group performing as flawlessly as possible while not clashing with each other. In the construction industry, this is especially true of 3D MEP (mechanical, electrical, plumbing) coordination, also known as 3D M&E coordination or 3D MEP Coordination, a key element of MEP design concerned with spatial configuration and the layout of building services trades (HVAC, pipe work, public health and electrical systems).

What is MEP coordination all about?

Well, it’s about detecting and resolving clashes among trades, architectural, structural, mechanical, electrical, plumbing and fire safety, before construction begins. It involves considering the location of all architectural, structural and MEP elements. Coordinating the updated designs of each discipline helps harmonise these individual designs. All of these disciplines contribute to a building’s fabric, structure and external envelope. Having coordinated MEP drawings helps contractors to refer, to fit and to install building services on site. It resolves clashes during the pre-construction stage, ultimately resulting in savings of time and costs on site.

Key considerations of MEP coordination include:

  • Clash detection of MEP (M&E) services with other MEP (M&E) services and architectural and structural elements
  • Performance and insulation when laying out the services
  • Service access and access locations for post installation maintenance
  • Bracketing and hanger locations, which are sometimes modelled to ensure fitting on site

Some of the software used in MEP coordination are:

Who’s involved?

Though the process of MEP coordination may vary from project to project. In some cases, MEP consultants prepare spatially organised MEP drawings or 3D Models, which are then passed on to the MEP contractor. The responsibility for installations and fabrication lies with the MEP contractor, who then develops coordinated drawings, adds detailing and considers fabrication, lagging, insulation allowance and installation efficiency. The MEP contractor may also be required to resize ducts, reroute piping, split the electric ladder, replace or modify equipment. These several tasks may lead to delays and extra expenses.

Traditionally, MEP coordination has been handled by contractors. The advent of BIM (Building Information Modelling) and BIM output requirements for consultants has changed that.

Consultants creating BIM models have to overcome challenges including:

  • Upgrading to 3D software and training teams for delivery in 3D
  • Sharing models with other disciplines earlier in the process
  • Increased accountability of their models due to collaboration
  • Developing spatial strategies for vertical and horizontal areas earlier in the process
  • Understanding installation requirements for a more effective layout
  • Collectively these challenges are helping to produce a more coordination solution during the design phase. 3D BIM modeling at the consultant stage also increases the MEP Coordination workload.

Earlier, MEP coordination involved the ‘sequential comparison overlay process’, which meant the functional design was prepared by a consultant, and the detailed design for each building service was developed by trade contractors. Trade contractors then sequentially compared installation drawings of the same scale on a light table and attempted to identify potential clashes. This process could be ineffective, lengthy and at times expensive.

Then, CAD (computer-aided design) came along. Still with no automated system for clash detection, it was up to the technical knowhow, experience and powers of anticipation of team members that drawings were created that site teams could use.

The arrival of BIM technology provided teams with a virtual 3D model that eased the process considerably. Design changes could be made with relative ease in a 3D model, eliminating the need to redraw the design, and more to the point, the model could show clashes between trades and disciplines. During MEP coordination, BIM technology enabled collaboration among stakeholders, sharing of data, simplification of tasks and financial savings. Rather than waiting for completed trade designs, 3D BIM coordination could potentially begin from the Design Development stage.

The benefits of using 3D BIM models for MEP coordination are as follows:

  • Eliminates most chances of clashes
  • Stakeholders can view and solve spatial issues
  • Helps prevents delays and disputes on site
  • Enables easy communication
  • Walk-throughs for demos

With the increased need for 3D BIM coordination, there is growing need for technically qualified professionals with the requisite skills. Such professionals may be difficult to find or train, thereby offshoring is becoming a popular alternative.

Continuing from the increasing demand for technically skilled professionals due to the rise in 3D BIM coordination, the focus now shifts to the technology employed in minimum deposit online casinos. These platforms offer convenience and accessibility, allowing users to engage in gaming with minimal financial commitment. As the demand for innovative technology in various sectors grows, so does the appeal of minimum deposit online casinos. The advantages of depositing small sums include reduced financial risk, affordability for casual players, and the opportunity to explore various games without significant investment. Additionally, advancements in payment processing technology ensure secure transactions, providing peace of mind to users.

Offshore services provided to consultants may include:

  • Interference-free 3D models
  • Design drawings for all key areas
  • Design schematics

Offshore services provided to contractors may include:

  • Installation standard 3D models
  • Installation drawings with sizes, dimensions and levels
  • Builders work/penetration drawings
  • Manufacturing and spool drawings
  • MEP coordination skills and knowledge
  • Technical specifications for equipment being used in the model
  • Industry standards and regional code standards
  • Software knowledge and application
  • Client-specific standards for model and drawing output
  • Project specific schedules and timing for phasing deliverables

Offshoring or outsourcing MEP coordination holds several benefits for Western firms, namely:

  • Saves recruitment time and costs– Hiring professionals who understand MEP designing and training them can be a difficult and lengthy process. Outsourcing MEP coordination to offshore BIM companies means their skills, experience and expertise can be used without in-house investments.
  • Manage project resourcefully– Cloud-based BIM software allows stakeholders across locations to access and update models in real time, eliminating the need for their physical presence during the designing or MEP coordination, effectively managing the design process.
  • High quality from experts– Outsourcing companies with the latest software and technology and tools can design and coordinate MEP models expertly, assuring high quality services.
  • Increased flexibility– An extensive pool of BIM professionals lets offshore BIM companies easily increase or decrease resources and infrastructure for sudden project shifts. Some of these companies may even offer their customers the flexibility to choose a variety of tools and technologies.
  • Data security assurances– Most outsourcing companies are bound by data security laws, helping to ensure the security of design data.
  • Focus on other areas to bring in revenue– While experts take care of the coordination, in-house engineers can focus on more productive, strategic and operational activities, increasing profitability.

As connectivity across global locations becomes increasingly extensive and global conditions change to facilitate work from offshore locations, more design and build firms in the West prefer to outsource 3D BIM coordination to countries such as India, which has a large pool of professional and experienced experts in 3D M&E coordination.
