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

International development observe has seen substantial modifications over current years, with the arrival of BIM being a key issue. Constructing Info Modelling, generally known as BIM, is a course of that entails the creation of 3D fashions, which permits designers and engineers to create correct development scheduling, estimate prices and adapt intelligently to design modifications. Correct constructing data fashions and exact constructing designs are created from the outset, which advantages all stakeholders within the development course of, notably MEP (mechanical, electrical and plumbing) designers. MEP (M&E) designers or engineers design MEP providers, whereas MEP contractors are then liable for spatial coordination, detailed design, fabrication and set up. Although BIM drives an efficient course of for MEP (M&E) design providers, there are some dangers concerned. We have a look at how these dangers might be mitigated.

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

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 position in making this attainable, particularly the usage of 3D fashions by way of Autodesk’s BIM 360 software. 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 security. Inside BIM 360, fashions might be utilised for 2D development documentation and the 3D coordination of trades. BIM 360 permits the management of processes by mission managers, subcontractors, designers and designers in any respect design phases. It permits the sharing of huge quantities of data between stakeholders and simple communication.

MEP designers can utilise architectural, structural and commerce fashions to plan intimately from the onset of a mission by designing in 3D. Basically, the method entails MEP design and set up workflows that can streamline planning, designing, coordination, fabrication, set up and development of a mission. Following architectural design, the MEP design engineer develops constructing providers design components, corresponding to lighting, cooling, heating, drainage, waste, hearth prevention and safety providers. Usually, the design engineer shouldn’t be concerned with the detailed spatial design of constructing providers. 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 guide’s design into an installation-ready MEP format and supply MEP store drawing providers. 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.

Subsequently, an efficient collaboration software could be required to:


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


BIM 360 Group with Collaboration for Revit (C4R) affords this. It integrates stakeholders and mission data right into a single cloud-based platform and improves high quality whereas lowering rework. Checklists can monitor security on website, tools might be tracked and asset knowledge might be collated. Any issues might 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 will not be correctly built-in and the incidence of errors within the MEP mannequin 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 consumer necessities happen the MEP design will likely be negatively impacted.


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

Price Estimation

The BIM course of may also help decide total prices and take off portions. MEP sources, labour and costs are thought of, however supplies availability and prices might differ over the period 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 many others. to develop exact MEP designs. Errors may show expensive.

Incomplete BIM Use

In frequent observe, BIM is used for a selected MEP goal slightly than for each a part of the design course of. These embrace:


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


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

BIM Mannequin Not Shared with Building Group

When 2D paperwork are printed from the mannequin, a few of the 3D knowledge will not be transferred. The development group might must design a brand new 3D mannequin, resulting in sudden modifications. 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 Potential to Mannequin Every little thing

Creating fashions is time consuming. Many particulars, corresponding to dimension, form, location, amount, and orientation with detailing, fabrication, meeting and set up data, might be included. It will not be attainable to create fashions for each portion of the design, leading to an incomplete total image.

MEP Design Handoff

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

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


  • Early BIM Adoption (Throughout Design Stage)


All mission stakeholders needs to be inspired to make use of BIM from the design stage, with clear tips 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 inside 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 needs to be a part of the contractual obligations. They will be unable to depend on MEP guide fashions in such a case.


  • Improved Coordination Abilities


MEP design in BIM presently utilises improved spatial coordination expertise throughout the design part. This might be a results of using extra technically certified professionals for these providers, 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 mannequin, very similar to a 2D drawing set was once. Revisions, modifications and file variations should be coordinated as effectively. Since 3D fashions are advanced, coordination should be monitored and managed to stop costly and pointless rework. Regardless that recordsdata might 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 reaching these designs. Specifying the position of BIM, its utilization, the stakeholders concerned and the challenges to be anticipated may also help optimise the advantages of utilizing BIM and minimise its dangers. The constructive impression of constructing data modelling will likely be felt for a while. Analysing and mitigating the dangers concerned in its use can solely profit the business and its gamers.
