BIM Course of Dangers for MEP Design Service and Methods to Mitigate Them

World development follow has seen substantial adjustments over current years, with the arrival of BIM being a key issue. Constructing Info Modelling, referred to as BIM, is a course of that entails the creation of 3D fashions, which allows designers and engineers to create correct development scheduling, estimate prices and adapt intelligently to design adjustments. Correct constructing info fashions and exact constructing designs are created from the outset, which advantages all stakeholders within the development course of, significantly MEP (mechanical, electrical and plumbing) designers. MEP (M&E) designers or engineers design MEP services, whereas MEP contractors are then chargeable for spatial coordination, detailed design, fabrication and set up. Although BIM drives an efficient course of for MEP (M&E) design services, there are some dangers concerned. We take a look at how these dangers may be mitigated.

Firstly, it’s helpful to grasp precisely what the BIM course of contributes to MEP engineering design. A BIM model helps visualise spatial MEP necessities. Detailed views are created for evaluation, and any clashes of spatial necessities are recognized and may be resolved at an early stage. Designs may be altered to mitigate any clashes, and these adjustments may be seen within the model.

The progress of the MEP design and coordination workflow course of has been supported and pushed by technological developments. BIM know-how has performed an vital function in making this attainable, particularly the usage of 3D fashions by way of Autodesk’s BIM 360 tool. BIM 360 is a cloud-based software program platform developed primarily for development, which employs checklists, tools monitoring and the monitoring of duties to enhance high quality and on-site safety. Inside BIM 360, fashions may be utilised for 2D development documentation and the 3D coordination of trades. BIM 360 permits the management of processes by challenge managers, subcontractors, designers and designers in any respect design phases. It allows the sharing of huge quantities of knowledge between stakeholders and simple communication.

MEP designers can utilise architectural, structural and commerce fashions to plan intimately from the onset of a challenge by designing in 3D. Typically, the method entails MEP design and set up workflows that may streamline planning, designing, coordination, fabrication, set up and development of a challenge. Following architectural design, the MEP design engineer develops constructing services design components, resembling lighting, cooling, heating, drainage, waste, hearth prevention and safety services. Normally, the design engineer isn’t concerned with the detailed spatial design of constructing services. Normally, it’s the MEP, or commerce, contractor who carries out the detailed spatial design and set up. It falls to the MEP contractor to transform the advisor’s design into an installation-ready MEP format and supply MEP store drawing services. At instances, fabricators creating ductwork or pipework components, electrical ladders or sprinklers in a module additionally contribute.

The BIM course of brings all stakeholders on to the identical platform at each design stage.

Due to this fact, an efficient collaboration tool can be required to:


  • Allow entry to MEP designers, architects, structural designers, MEP contractors
  • Host varied codecs for information and paperwork
  • Ease communication
  • Allow designers and shareholders to work on the identical fashions and share design information


BIM 360 Workforce with Collaboration for Revit (C4R) presents this. It integrates stakeholders and challenge info right into a single cloud-based platform and improves high quality whereas lowering rework. Checklists can monitor safety on web site, tools may be tracked and asset information may be collated. Any issues may be resolved early within the design course of, minimising delay, value and rework.

BIM Course of Dangers for MEP


If architects, modellers and designers don’t talk correctly, designs is probably not correctly built-in and the incidence of errors within the MEP model will enhance.

Constructing Code Understanding

Shopper wants and native code necessities are of paramount significance and should be clearly understood. If misunderstandings of constructing codes and shopper necessities happen the MEP design will probably be negatively impacted.


Stakeholders should coordinate successfully. Any modification executed by any MEP service must be communicated to all different trades. Failure to take action can create hazards on the challenge implementation stage.

Price Estimation

The BIM course of may help decide general prices and take off portions. MEP assets, labour and costs are thought-about, however supplies availability and prices might fluctuate over the length of the design and implementation, affecting value estimation.

Technical Knowhow

Efficient BIM utilization requires in-depth information of BIM know-how and Revit, Navisworks, and so forth. to develop exact MEP designs. Errors may show pricey.

Incomplete BIM Use

In widespread follow, BIM is used for a selected MEP goal quite than for every a part of the design course of. These embody:


  • Remodelling or renovation
  • Materials takeoffs and estimation
  • Design fashions by contractors
  • Detailed fashions of MEP parts


Until the BIM scope and output are precisely outlined, the supposed use of the BIM model might not happen.

BIM Model Not Shared with Building Workforce

When 2D paperwork are printed from the model, a number of the 3D information is probably not transferred. The development staff might must design a brand new 3D model, resulting in sudden adjustments. Designers might not share fashions with contractors as a result of they’re incomplete or don’t tally with the development paperwork, creating errors and tensions.

Not Doable to Model Every part

Creating fashions is time consuming. Many particulars, resembling measurement, form, location, amount, and orientation with detailing, fabrication, meeting and set up info, may be included. It is probably not attainable to create fashions for each portion of the design, leading to an incomplete general image.

MEP Design Handoff

Contractors historically obtained 2D line diagrams, schedules and specs of the design from MEP designers. At present, an growing variety of MEP design engineers create fashions, elevating confusion about who’s chargeable for duct placement, tools placement and coordination duty – designers or contractors. Fashions created by MEP designers is probably not spatially correct sufficient throughout the early phases.

Nonetheless, there are a number of methods to mitigate these shortfalls, resembling:


  • Early BIM Adoption (Throughout Design Stage)


All challenge stakeholders must be inspired to make use of BIM from the design stage, with clear pointers for its use. If BIM is adopted at a later stage with out clear specification of its objective, the outcomes might be confusion, wastage of time and growing prices.


  • Outlined Roles throughout the BIM Course of


Design and modelling roles should be clearly outlined earlier than starting design. If MEP subcontractors want to offer MEP BIM, with correct routing, attachment particulars and tools connections, they should be clearly knowledgeable of this and it must be a part of the contractual obligations. They will be unable to depend on MEP advisor fashions in such a case website link.


  • Improved Coordination Expertise


MEP design in BIM at present utilises improved spatial coordination expertise throughout the design section. This might be a results of using extra technically certified professionals for these services, and as a consequence, contractors are introduced with extra correct fashions to work with.


  • Accountability for Coordination


Inside coordination is important for a viable BIM model, very similar to a 2D drawing set was once. Revisions, modifications and file variations should be coordinated as nicely. Since 3D fashions are complicated, coordination should be monitored and managed to stop costly and pointless rework. Though information may be hosted within the cloud, it’s advisable to take care of backups.

It’s a certainty that exact, efficient design with fewer errors is feasible utilizing BIM however there could also be challenges in attaining these designs. Specifying the function of BIM, its utilization, the stakeholders concerned and the challenges to be anticipated may help optimise the advantages of utilizing BIM and minimise its dangers. The optimistic influence of constructing info modelling will probably be felt for a while. Analysing and mitigating the dangers concerned in its use can solely profit the trade and its gamers.
