BIM is applied as a common documentation storehouse for electrical trade that can coordinate electrical trades, develop prefabrication openings, reduce rework, raise productivity, decrease labor costs, and get better consistency of the work product.
BIM will integrate all the electrical parts in a single respiratory model for efficient electrical building design. The complete building model along with mechanical, electrical and plumbing systems, will be transferred to an integrated database in which everything is interrelated. This database presents authentic, coordinated and consistent design information and documentation that differentiates BIM. As for illustration an electrical engineer prefers to observe the architectural workset frequently but clasp the perceptibility of the structural workset on or off to go with the design requirements.
Application of BIM for electrical project can improve constructability and speed up the schedule, save time and money for the owner including the project team.
BIM creates a collaborative environment among the team members. The general contractor (GC) will be involved in designing and executing the BIM execution plan to find out what will be modeled and at what level of detail. It will help to generate effective electrical coordination.
BIM mechanically coordinates all design documentation. Electrical documentation, for example, electrical plans and panel schedules become reliable as all the drawing sheets, views, schedules, reports and so forth are existing in the same underlying database.
BIM generates a virtual model of all the electrical systems in 3D and allocate that information with the whole project team. The drawings, specifications, and construction details are integral to the model, which includes building geometry, spatial relationships, geographic information, and quantity properties of building components. Therefore, any design issues/construction clashes among the electrical trade can be identified, manipulated, analyzed and resolved in a virtual surroundings well before the commencement of the actual construction.
BIM offers data-centric approach with a comprehensive view of the building model and systems. The electrical engineer can evaluate the electrical requirements on mechanical equipment contained in the design and apply BIM to mechanically configure voltage and power load requirements to dynamically revise in panel schedules and mechanical equipment specifications.
The intelligent property database corresponds to the “I” in BIM can be dug out from the model to schedule and annotate the drawings for the application of electrical engineering, take-off, and prefabrication. As for instance, by utilizing intelligent property data to conduit and parts, the electrical engineer is able to instantly execute a take-off of the conduit to verify the number of linear feet or quantity of hangers. The method drags live data from the actual model components in the drawing by annotating all of the conduit elevations.
BIM creates realistic lighting visualizations for electrical engineers to study lighting levels and design directly in the system.
BIM creates electrical system modeling with electrical devices and equipment such as lighting fixtures, transformers, generators, panel boxes, etc. Electrical engineers will be in a position to model the power and lighting circuitry of the building spaces. At the time of electrical system modeling, the electrical engineers arrange the light fixtures, power devices and equipment in the model and then forms a circuit connected to a distribution panel. The electrical engineers can easily characterizes wire types, voltage ranges, distribution systems and demand factors to guarantee the compatibility of electrical connections in the design and check for overloads and mismatched voltages.
Electrical circuit model generated from BIM facilitate electrical engineers to work out the estimated demand loads on feeders and panels. These loads are being utilized to effectively size equipment in the design environment. Load balancing becomes simple while managing circuits.
BIM Systems can estimate lighting levels in rooms mechanically depending on the lights set in the space. The electrical engineer can just describe the reflectivity values of the room surfaces, connect industry-standard IES data files to lighting, describe the calculation workplane height and the average estimated illumination value for the room will be automatically calculated. The electrical engineers may keep calculated illumination in a report for the purpose of the design document.
