Has BIM Changed MEP Design Workflow?

How Has BIM Changed MEP Coordination? | by Kuldeep Bwail | Medium


The MEP plan and establishment work process includes various partners and gatherings that are all in all answerable for managing a progression of stages that will bring about the structure designing (or building administrations) to be arranged, planned, spatially organized, manufactured, introduced, dispatched and kept up. Commonly, the structure administrations configuration stage follows the underlying engineering plan, from which point it can ordinarily be planned in corresponding with additional compositional just as auxiliary plan changes.

The designing groups that regularly configuration building administrations arrangements are for the most part in one of two gatherings. The primary gathering is ordinarily the structure fashioner, otherwise called the expert designer or the plan engineer. It is the part of the plan designer to work intimately with the draftsman to build up the general structure designing components including lighting, cooling, warming, seepage, squander, fire avoidance and insurance administrations. Generally, the plan architect won’t be engaged with the definite spatial plan of these administrations. Rather the itemized spatial plan and establishment would ordinarily be dealt with constantly party, known as the MEP temporary worker (M&E contract based worker) or exchange contract based worker. The MEP or exchange temporary worker is liable for advancing the underlying advisor plan into a useful and establishment prepared structure administrations arrangement.

In certain examples, there is likewise an outsider included – the fabricator, who will be answerable for making MEP parts, for example, ventilation work or pipework components or sometimes pre-created arrangements that comprise of pipework, electrical stepping stool, plumbing, ventilation work and sprinkler inside an edge (module) that is conveyed to site for establishment in risers, plant rooms and hallways.

This article is worried about the part of the MEP fashioner and MEP temporary worker, explicitly, the concentration for this article is to examine how BIM (Building Information Modeling) has affected the MEP plan work process between the planner and the contract based worker.

Current MEP BIM Workflow Options

Basically there are five distinctive MEP plan work process situations that at present exist and these will be talked about in the article. They are as per the following

Conventional 2D plan and 3D BIM coordination

3D MEP plan and 3D BIM coordination

Creators 3D BIM plan and coordination

Contractual worker 3D BIM plan and coordination

General contractual worker 3D model coordination

Conventional 2D Design and 3D BIM Coordination

Considering the conventional MEP approach first, this is the place an advisor will make 2D configuration yields, which incorporate 2D plan formats, 2D segments and MEP (M&E) schematics. This will demonstrate the plan aim for the structure dependent on the utilization determined by the designer. When the specialist has finished this plan data he will give the data to a MEP contractual worker who will be answerable for making the MEP facilitated arrangement. This article expects that the temporary worker will make a spatially organized 3D BIM model utilizing BIM instruments, for example, Revit MEP and Navisworks. The contractual worker will utilize the plan data and make an establishment prepared arrangement which considers establishment, proficiency of line runs or pipe twists, space for slacking and hanging the administrations, access for post introduce upkeep, etc. This customary MEP approach, from a 2D plan to a 3D model has existed for the recent many years and permits the contractual worker to include extra data into the model that can be utilized by him and by offices the board organizations after the establishment. The utilization of the 3D apparatus, for example, Revit is obviously helpful as it is a clever model, with parametric parts and hence, just as permitting the temporary worker to recognize and resolve conflicts before any time is spent nearby, it has different utilizations and applications where model ‘data’ is utilized and depended upon.

3D MEP Design and 3D BIM Coordination

The second work process strategy is all the more straightforwardly affected by BIM. As the MEP creator, one will utilize BIM apparatuses to make a 3D model and related drawings during his underlying plan stage (instead of a 2D plan) before this data is given across to a MEP exchange contractual worker. The MEP configuration designer will commonly make a 3D model because of client particulars and necessities for a BIM model, as much of the time a unified model (which joins different orders in a solitary model) is required by the customer for a week after week survey and thus the MEP expert can’t just give a lot of 2D drawings. In this work process, the BIM model is successfully a 3D portrayal of what might some way or another be a 2D deliverable. It will consequently comprise of zones where further changes are as yet required by an exchange contractual worker. Such models incorporate the utilization of library things instead of explicit MEP exchange temporary worker acquired components that might be utilized in the model. The formation of a 3D BIM model at this stage by the expert is additionally dependent upon numerous building and auxiliary model changes. These have a thump on impact on the MEP arrangement as it is adequately a work-in-progress model for MEP with consistent building and basic changes and hence will never have a similar degree of effectiveness, as far as format of administrations, contrasted with a MEP model where the compositional and auxiliary models are solidified. The drawback of this work process strategy is obviously the additional time taken to make a BIM model by the advisor group. Added to this issue is the way that 3D displaying aptitude and abilities inside a counseling designing group can some of the time be restricted. When the expert finishes his model and passes it to the MEP temporary worker, the choice regarding whether the contract based worker ought to adjust the model or start the demonstrating cycle from the beginning is truly founded on the nature of the model to begin with. Actually the two situations will exist, sometimes the MEP exchange temporary worker is in an ideal situation beginning the BIM model again utilizing just the 2D plan drawings that are made by the advisor from his BIM model, while in some uncommon cases the exchange temporary worker will utilize the specialists MEP BIM show and adjust and alter it with his changes, to prepare the model for establishment. In the two situations, the MEP temporary worker will consistently hope to make esteem designing increments and changes to the model just as acquirement drove model changes.

Fashioners 3D BIM MEP Design and Coordination

The third MEP plan work process technique is a more unadulterated and direct outcome of BIM and it entirely begins to advance the advantage of BIM all the more altogether as it draws nearer to ‘virtual plan and development’ points of the business. In this work process the methodology of configuration engineer is to make a BIM model that is spatially planned and that is utilizing the real determined segments for the task. Regularly, the advisor during this stage will have a more extended timeframe to make the model, permitting him to ingest the progressions from basic and engineering disciplines as they progress through the specifying stages. The way that the model is then planned with the structure and engineering just as other MEP administrations permits the advisor to make a model that is being made by an establishment standard that is presently more usable by an installer or fabricator. At the point when the model in this work process strategy is given to a temporary worker, the temporary worker may in any case wish to roll out definite improvements and changes in a series of significant worth designing. Commonly, the temporary worker will utilize a similar model in this work process and make changes to the model gave by the MEP plan expert. Also, it is plausible that the expert designer won’t have given alter (stature) levels or measurements from gridlines and dividers for the MEP administrations on his drawings. In such cases the contractual worker will along these lines need to make more detail in the drawings, however again contractual worker could utilize the advisor’s drawings and progress them in more detail for his/her utilization.

Temporary worker 3D Design and Coordination

The fourth work process technique includes MEP contractual workers (or exchange contract based workers) taking on the plan obligation just as the coordination duty. While the coordination duty is a set up range of abilities with experience of creating nitty gritty and exhaustive vertical and level procedures for coordination being important for the contractual worker’s center aptitudes, the plan obligation is another component for the temporary worker. This was customarily known as a plan and construct approach; in any case, it is currently turning out to be progressively basic particularly in situations where organizations are trying to have quick plan and point by point coordination finished. Ordinarily, the parts to be utilized will be determined by the end customer, permitting the contractual worker to plan and show before making his itemized facilitated drawings from the model, to permit establishment and manufacture if necessary. The explanation that this specific work process technique isn’t the most famous at present is basically because of the volume of work on the lookout and furthermore the plan duty that likewise must be expected as much of the time, contract based workers may not wish to acknowledge this danger or to be sure they might not have the assets to finish the plan work. For this work process strategy to exist at all implies that the contractual worker needs to utilize configuration staff legitimately and give plan risk protection to permit him to plan the MEP arrangement just as introduce it. The advantage of this work process choice is clearly the time effectiveness that is acknowledged and along these lines the money saving advantage, as the expense of using temporary worker asset will ordinarily be lower contrasted with costly plan designing firms. Nonetheless, it accompanies some danger as the plan ability that plan engineers have can’t be effortlessly duplicated by contractual workers, regardless of whether they do utilize in-house groups.
