Since the architecture, engineering and construction (AEC) business faces tremendous pressure to provide optimal projects within strict deadlines, improving process efficiency and reducing rework is unquestionably the need of the actual hour. The design and construction-related rework is among the critical factors that negatively affect productivity, profitability as well as timely completion of tasks for both contractors as well as owners. Besides, it effects designers, subcontractors, MEP (M&E) technical engineers, consultants and the whole downstream chain. In comparatively larger and much more complex projects, the design-build rework can negatively influence the whole project workflow, delay task delivery, and cost a lot more than what was originally believed.
As mep coordination drawings, electrical, and plumbing systems take into account a significant value from the project, the prudent utilization of building information modeling (BIM) resources to effectively coordinate MEP (M&E) techniques helps reduce rework as well as increase productivity. On another hand, the lack of well-planned interdisciplinary MEP (M&E) coordination leads to duplication of efforts, main interferences and design clashes upon site, as well because fabrication changes and mistakes.
Since BIM requires thorough pre-construction planning and multidisciplinary coordination, its adoption through the MEP (M&E) team raises technical interoperability among numerous members during building providers coordination. In BIM-led MEP (M&E) coordination, creating services designers, consultants, and subcontractors are participating during the design as well as planning stage. One of the very crucial factors for a highly effective and accurate coordination exercise is to select a specific protocol with regard to creating virtual architectural, structural, mechanised, electrical, plumbing and fire protection types of the same facility. Consequently, the team should agree with mechanisms to merge the actual models from different trades and produce a combined coordinated services MEP design.
For instance, the designers use design development drawings application to organize architectural BIM models which accurately represent elements, for example walls, doors, windows, ceilings, as well as casework. Furthermore, each of these elements has a variety of parameters, including thickness, elevation, materials, and texture, amongst others. Using this architectural model like a reference point, a structural model is going to be created using Revit Framework which features vertical as well as horizontal structural framing, fundamentals, and slabs.
Subsequently, the actual MEP (M&E) contractors as well as subcontractors design separate versions for mechanical, electrical, Engineered Drawings as well as plumbing systems using three dimensional MEP modeling software (such because Autodesk MEP and Revit MEP). Generally, the mechanical models consist of HVAC ducts, piping assemblies, hangers, diffusers, as well as pipe insulation, to name several. The electrical models may represent details concerning conduits (feeder as well as underground), junction boxes, illumination systems, cable/wire bundles, as well as cable trays, amongst other people. The plumbing system design includes storm and sewage outlines, plumbing assemblies, hot/cold drinking water piping, and other niche equipment.
Once the particular architectural, structural engineering drawings, and building services models have been in place, they have to become merged and taken right into a clash detection application as well as specialist interference-checking application, for example Autodesk Navisworks. Any clashes as well as inconsistencies, including the geometry-related difficult clashes, the clearance clashes, as well as workflow clashes are discovered. Post clash detection, the combined services versions and drawing sets need to be prepared to show exactly how MEP (M&E) systems fit together within the same space.
As an effect, the MEP (M&E) contractors and fabricators receive well-coordinated as well as clash-free building services sketches on site, which drastically reduces the amount of installation conflicts in the actual field. Additionally, MEP (M&E) BIM coordination leads to more assemblies being prefabricated off-site inside a controlled factory environment, which improves the logistical circulation on site. Moreover, another positive results of BIM-driven MEP (M&E) coordination physical exercise is relatively lesser quantity of change orders and RFIs (request with regard to information).
All the above results of mep coordination drawings help to make the design-build process better by increasing project’s routine compliance whilst reducing style and construction-related rework.
