World development follow has seen substantial modifications over current years, with the arrival of BIM being a key issue. Constructing Info Modelling, often called BIM, is a course of that includes 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 info 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 services, 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 services, there are some dangers concerned. We take a look at how these dangers might 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 might be resolved at an early stage. Designs might be altered to mitigate any clashes, and these modifications might 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 necessary function in making this potential, particularly using 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, gear monitoring and the monitoring of duties to enhance high quality and on-site safety. Inside BIM 360, fashions might be utilised for 2D development documentation and the 3D coordination of trades. BIM 360 permits the control 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 straightforward communication.

MEP designers can utilise architectural, structural and trade fashions to plan intimately from the onset of a mission by designing in 3D. Generally, the method includes MEP design and set up workflows that may streamline planning, designing, coordination, fabrication, set up and development of a mission. Following architectural design, the MEP design engineer develops constructing services design parts, akin to lighting, cooling, heating, drainage, waste, fireplace prevention and safety services. In most cases, the design engineer is just not concerned with the detailed spatial design of constructing services. Normally, it’s the MEP, or trade, 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 occasions, fabricators creating ductwork or pipework parts, 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 could be required to:


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


BIM 360 Staff with Collaboration for Revit (C4R) presents this. It integrates stakeholders and mission info right into a single cloud-based platform and improves high quality whereas decreasing rework. Checklists can monitor safety on web site, gear might be tracked and asset information might be collated. Any issues might be resolved early within the design course of, minimising delay, price 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 prevalence 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 consumer necessities happen the MEP design will probably 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.

Value Estimation

The BIM course of will help decide general prices and take off portions. MEP assets, labour and costs are thought of, however supplies availability and prices might differ over the length of the design and implementation, affecting price 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 might show expensive.

Incomplete BIM Use

In frequent follow, BIM is used for a particular MEP goal quite 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 parts


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

BIM Model Not Shared with Development Staff

When 2D paperwork are printed from the model, among the 3D information will not be transferred. The development staff might must design a brand new 3D model, 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 Model Every part

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

MEP Design Handoff

Contractors historically acquired 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, gear placement and coordination accountability – designers or contractors. Fashions created by MEP designers will not be spatially correct sufficient in the course of the early phases.

Nonetheless, there are a number of methods to mitigate these shortfalls, akin 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 pointers for its use. If BIM is adopted at a later stage with out clear specification of its goal, 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 supply MEP BIM, with correct routing, attachment particulars and gear 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 advisor fashions in such a case bim management services.


  • Improved Coordination Abilities


MEP design in BIM at the moment utilises improved spatial coordination abilities in the course of the design part. This might be a results of using extra technically certified professionals for these services, and as a consequence, contractors are offered 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. Revisions, modifications and file variations should be coordinated as effectively. Since 3D fashions are complicated, coordination should be monitored and managed to forestall costly and pointless rework. Though 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 attaining these designs. Specifying the function of BIM, its utilization, the stakeholders concerned and the challenges to be anticipated will help optimise the advantages of utilizing BIM and minimise its dangers. The constructive affect 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.
