Brief over of Revit and Revit Families

Revit can be termed as a Building Information Modeling (BIM) software. Revit contains a commanding parametric 3D modeling database motivated program which facilitate BIM to happen. Revit empowers users to design with 2D drafting elements.

The database incudes information about a project at different building life cycle phases from concept to construction to decommissioning. This may be called 4D CAD where time is the fourth dimension.

How Revit Works :-
Revit utilize .RVT files for accumulating BIM models. A building is constructed with 3D objects to generate walls, floors, roofs, structure, windows, doors and other objects as required. These parametric 3D building objects (windows or doors) or 2D drafting objects (surface patterns) are recognized as "families" and are saved in .RFA files, and imported into the RVT database.

A Revit model contains a single database file characterized with plans, sections, elevations, legends, and schedules. If any alteration occurred in one representation of the model (a plan) are circulated to other representation of the model (elevation) as alteration to each representation of the database model is provided to one central model. As a result, Revit drawings and schedules are constantly coordinated concerning the building objects exposed in drawings.

Revit can carry out conflict detection when different components of the building are taking up the same physical space. Like many BIM-software, Revit is compatible with open XML-based IFC standard which facilitates a general contractor to involve BIM-based workflow from the diverse discipline consultants of a building project.

Modeling with Revit :-
Revit includes a work environment that lets users to extrude, revolve, trace the path of, or morph shapes drawn on a 2D plane so as to create them into 3D objects, along with perform these actions already made solid objects to cut or reorganize them.

The users are able to generate realistic and precise models of objects, as well as import premade models from other programs. The reproductive components of an object are retained to be parametrically controlled.

Revit Families :-
Revit families are the pre- made reusable objects contained within a Revit model. These objects are compiled with different parameters & parallel visual graphical representation with engineering exactness related to an entire class or group (Generic). Revit families are made with dimensions controlled by parameters (parametric) facilitating users to revise the component by altering predefined values such as height and width. Revit families generate schedules & establish LEED ratings, lessen building costs & denote products directly in your model. Revit family consist of content in 3D & 2D Revit, 3D dwg & 3ds Max file formats.

System families
It includes categories like walls, roofs, ceiling, stairs, railings, ramps, mullions, curtain panels and topography surfaces. Some predefined types are utilzed to form these families associated with each project. These families also contain creation methods specific to the type of family. The user will be able to generate new types of system families by replicating accessible types and editing their parameters.

Standard families
These families will be formed outside of the project environment by means of the family editor. They are accumulated in an external library & will be loaded into a project for utilizing with any point. Every standard family refer to a specific Revit category so that when it’s loaded into a project, to approves the graphic rules defined for its category in the object styles dialog while loaded into a project. This will keep uniformity of graphic all through the project.

This also guarantees that when you schedule a category you will get all elements that belong to that category. Standard families have their own file format extension (.rfa) and can be stored outside the project environment for later use in other projects.

Benefits of BIM for electrical engineers

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.

BIM can be utilized as powerful post occupancy evaluation tool for the maintenance and post-occupancy management of assets

Post-occupancy evaluation or POE is the progression of methodically assessing the performance of buildings after being built and occupied for some time. POE will highlight on the performance of the architectural and engineering systems, the management procedure applied to the design and construction.

With the advancement of time, the concept of Building Information Modeling has changed gradually. BIM has now changed from a simple planning and design tool to powerful post-occupancy management tool. BIM accumulate the data throughout the construction process and these data can be utilized seamlessly for the maintenance and post-occupancy management of assets (buildings and infrastructure), long after these has been finished.

BIM as a post occupancy management tool gather, store, and share information about successes and failure in processes, products and other building-related areas in order to get better quality and life cycle cost of future buildings. These informations can also be utilized with the planning, programming, and design processes for new facilities to build on successes and get rid of repeating mistakes.

BIM can contain the documentation of owner performance obligations, the design objective and justification, verification and validation of design strategies & decisions to develop actual building performance.

BIM can provide an array of opportunities for project stakeholders that may range from faster communication among team members, the smooth continuation of the project, early detection of errors before happening onto the job site (there zero change orders), precise construction cost estimation and less waste with a mechanical process. Even with the time required by a steeper learning curve, the building was completed ahead of schedule.

BIM contains accurate geometry and information to aid in scheduling, cost comparisons, fabrication, construction, and facility operation.

Construction sectors can experience a low-carbon future with BIM as the tool comes up with greater productivity, risk management, improved margins and sustainability.

After completion of the project many organizations like hospitals and universities, apply sensors and examines overlaid on 3D graphics to analyze the efficiency of the finished structure and its interior spaces. Besides, BIM can also be applied to inventory space use by some facility management departments.

BIM provides an uninterrupted procedure of consistently appraising the execution and/or potency of one or more aspects of buildings like accessibility, aesthetics, cost-effectiveness, functionality, productivity, safety and security, sustainability, environmental design evaluations, environmental audits, building-in-use assessments, building evaluation, facility assessment, and building performance evaluations.

By applying BIM the owner can better realize the effect of early design delivery decisions on long-run efficiency and effectiveness of buildings as well as building delivery processes and decisions on customer response both in the beginning and over the life cycle of the building.

BIM contains specified information set known as COBie1 which delivers uniform and structured asset information helpful to the owner-operator for post occupancy decision-making.

BIM can also be implemented for enhancing Globalization of the construction supply chain and more homogenization and greater consistency of basic construction-client information demands. This information is now progressively driven by national regulation on energy performance and carbon' accounting.

    BIM and 3D laser scanning

    3D Laser scanning is the process that generates highly accurate location information to produce uniformly precise 3D models which later on can be utilized to repair, renovate, estimate the need for structural upgrade or seismic retrofitting, design visualization and optimize our infrastructure for a more sustainable future. So the progression of adapting old structures for new purposes or “adaptive reuse” in view of the current economic climate and sustainability efforts is possible with 3D laser scanning.

    3D laser scanning provide detailed modeling or information for modeling and any development, any addition, virtually any view situation or impact, any re-creation or any topography impact can be prepared digitally.

    The level of detail and the completeness that in many cases only laser scanning can provide.

    Now-a-days laser scanning combined with a BIM-centric process can support a building’s entire life cycle to a great extent. It develops resource efficiency of buildings, which is a basis of sustainability efforts today. The architect and engineers armed with this complete model can now create improved informed intervention early on the design stage and provide a real impact on design decisions for the future of the building or other infrastructure. Long term facility management systems can be arranged for future maintenance and upgrade projects.

    Laser scanning can be applied to support the detailed documentation of the as-built to instigate a facilities program for the long-standing management of an asset. 3D laser scanning facilitates the provision for quick, precise as-built data of large, complicated, and often dilapidated buildings and their supporting infrastructure (water pipes, sewers, drainage, etc.). The as-built data is utilized for planning and design process mainly where sustainability and reprocess of existing infrastructure become an important factor in areas like energy refits. Designers are able to evaluate the prospective reuse of buildings as well as understand the original construction.

    In a historical preservation project exclusive of laser scanning it is not possible to assure that the contractor is deliver the desired product.

    By applying laser scanning combined with a BIM-centric process mechanical, electrical, and plumbing (MEP) spaces within the facility can be scanned and documented from several vantage points. These 3-D laser scans contained all accessible facilities and installed components as well as mechanical, electrical, and plumbing fit-outs; air handling duct work; and structural ladders, catwalks, and platforms.

    The scanner accumulated raw data of all elements in the facility in the form of a dense 3-D spherical point cloud made up of millions of 3-D coordinates. In the end, these 3-D laser images formed a high-definition survey within the facility. After the completion of the scan, the scanning images are brought into BIM software by means of the Pointools plug-in to generate engineered geometry-based models.

    Tools for 3D Data Capturing
    Low cost survey:
    • Laser Disto
    Surveying :
    • Robotic total station
    3D Imaging, Laserscanning :
    Upcoming technologies :
    • Photogrammetry
    • – Dense image matching
    • Vision SLAM
    • – via smart mobile device or UAV helicopter
    • Range Cameras
    • – E.g. PrimeSense, Microsoft

    How project stakeholders can apply BIM in their work process

    BIM can be applied as a work process and means of communicating with one another in the project delivery method to illustrate the end product (the model itself).
    BIM generated a virtual process that covers all characteristics, disciplines, and systems of a building inside a single, virtual model facilitating all project stakeholders to work together more precisely and competently. Thus BIM creates a collaborative design process.
    After the creation of the model, team members are continuously clarifying and regulating their portions in accordance with owner preferences, system's adaptability and design intention to maintain the accuracy of the model before the commencement of the actual project. If any modification is made by the project team members, it affects the entire model, creating continuous communication
    After that the model itself is utilized to exchange information for design concepts to the owner. The model is also applied for estimating materials take-off for cost estimation and for conflict detection to electronically verify the proper designing of the building system. BIM can trim downs change orders by making changes electronically rather than on the job site which can get a huge saving in time and money for project schedule and budget.
    Design information from all disciplines as for example from architectural designs and specifications to structural and mechanical systems information such as HVAC Ducting, piping and structural slabs, columns and shear walls are provided in the BIM database. The database includes and combines all elements of a finished building to one main database of linked project information. If any, the BIM database would mechanically rearrange all connected elements implanted in the interrelated database to communicate with any changes occurred with one element of the design.  A BIM database can surpass it’s 3D modeling capability and perform for 4-D (construction scheduling) and even 5-D (cost flow analysis). The database could significantly lessen waste in construction as well as time delays raised  by RFIs and change orders. 
    BIM has also shifted time spent in various phases of design, placing more emphasis in the initial design phases and less in the construction documentation phase. Whereas with traditional CAD processes the bulk of the time was spent preparing construction documents, BIM requires more time up front, fully develop the design and model. When a BIM project goes into construction documentation, all that’s left to do is decide where to cut sections through the building and print the documents.

    BIM can flawlessly gather in and incorporate the input and flow of information among design and construction professionals to make the entire process more efficient and reduce delays and cost overruns.
    BIM can characterize a design as objects in the form of indistinct and undefined, generic or product-specific, solid shapes or void-space oriented (like the shape of a room), which contains their geometry, relations and attributes. The geometry possibly will be 2D or 3D. The objects may be conceptual and are constructed detailed. A building model is described by compiling together these objects. If an object is modified or moved, BIM tool then starts to dig out diverse views from a building model for drawing production and other application. These diverse views are mechanically constant i.e. the objects are all of a constant size, location, specification. Drawing uniformity reduces many inaccuracies as each object instance is defined only once.
    Modern BIM technology identifies objects parametrically. Here the objects are identified as parameters and relations to other objects, in order that if a correlated object is modified, this one will also. Parametric objects mechanically reconstruct themselves in relation to the rules implanted in them. The rules are uncomplicated, involving a window to be wholly within a wall, and moving the window to the wall, or complex defining size ranges, and detailing, such as the physical connection between a steel beam and column.

    How a BIM model can be utilized for commissioning

    BIM for commissioning is the progression of synchronizing and incorporating as-installed information and documentation from construction quality and commissioning agendas in the field and at the point-of-construction to facilitate competence in the delivery method of a construction project and in continuing operations and energy use.

    A BIM model can be utilized for commissioning to verify its accuracy. This puts the model up for "Facility Management" from the BIM model.

    The BIM act as a digital dashboard, documenting every step, facilitating operators a very speedy, precise picture of the accurate position of the commissioning process.

    Building owners can commission this hi-tech technology with foresight and planning to get the best out of the BIM model for their building. The owner should train themselves on what value will be taken out from BIM and how it affects their business, makes efficiencies and in due course saves them money.

    If a BIM model includes rich content then it will become more functional and precious in the downstream for maintenance and operations.

    BIM selectively provides information with its conceptual methodologies, realistic methods and technical programs.

    An apparent focus for your model is necessary as it makes the most significant part of the commissioning procedure. The level of detail in a BIM model can straightforwardly make an effect on scheduling and costs.

    A BIM deliverable should be distinctive in comparison with the building it stands for. In this case the user should know what the model contains and how detailed it should be. To make sure that your deliverable will fulfill your requirements, the following steps should be taken during commissioning.

    Initially make out how the model will support facilities management. BIM facilitates you achieve superior control over areas similar to energy spend, space planning, and asset management – which of these benefits are you seeking?

    When you are aware of the model’s scope, deliver background data to the design team. In the case of commissioning for energy management, assist the contractor to collect acknowledged data to be utilized for populating the model.

    For energy analysis, the owner should produce more information like information about the mechanical systems, occupancy, building schedule, utility bills, rough estimates of floor-to-ceiling heights, and glazing percentages to create a better building.

    The project stakeholders utilize BIM on the construction job site and at the point-of-construction to leverage the structured data sets and associated documents for executing a wide range of field programs and daily activities as described below :-

    Deal with advanced tasks as well as start, end, planned and actual dates, along with start-up, testing, adjusting and balancing (TAB), functional tests, operational procedures, training, handover and warranty.

    Bring up to date as-installed information from equipment, sub-systems, systems and correlated work in the field, along with status of work arranged to date, physical location and nameplate data such as serial numbers.

    Supervise track and task problems related to work to complete or correct to guarantee that physical work match to the contractual obligations and equipment performance act in accordance with the project specifications.

    Execute and record the results of processes, ensures and tests using standardized QA/QC and commissioning (Cx) checklist templates, for instance pre- and practical performance tests and manages point-to-point checks.

    Attach and chalk up photos of as-installed conditions for the record, to balance warranty management and risk management programs after surrender through the warranty period.

    Connect and chalk up documents and drawings, for example equipment plans and reflected ceiling plan (RCP) interface layouts, piping & instrumentation diagrams (P&IDs), manufacturer’s certs and 3rd party test results.

      How BIM provides benefits to various project stakeholders

      BIM can be defined as a quantifiable illustration of the physical and functional characteristics of a facility as well as interrelated project/life-cycle information with open industry standards to update business decision making for recognizing better value. BIM is applied for presenting and visualizing building components, construction sequences, resource allocation and other disciplines of the construction process in a virtual environment.

      Some of the prominent benefits of Building Information Modeling are:
      • A robust design sequence with reduced risk of material and on-site problems
      • BIM is a combination progression from various domains, technology, and product solutions
      • Enhance understanding and minimize risk providing enough information to understand life cycle cost estimation
      • BIM solidly sets robust life-cycle management procedures inside technology to allow quick execution, scalability, transparency, collaboration and promise consistency.
      • BIM, together with Cloud Technology facilitates well-organized building life-cycle management
      • The ‘I’ within BIM refer to information regarding standardized definitions, data architectures, taxonomies, metrics, etc. It is the core component of BIM
      • Decrease capital costs throughout improved supply chain management
      • Trim down energy costs by providing optimized sustainable designs

      How BIM creates energy efficiency for building design

      BIM plays an important role in creating sustainable design which results in better building. BIM can be applied to support energy performance analyses and operational practices on a project-by-project need basis. So BIM should be implemented at the initial concept stage – well before key design decisions are taken as low-energy can affect the overall design process of a building.

      Throughout the life duration of a building, around 80% energy is incurred with heating and cooling of rooms and for other equipment – the outstanding 20% is associated with the production of materials, construction and demolition of the building.

      Detailed simulation of energy efficiency completed in the initial stage of design will be the base task in the detailed design of exterior enclosures and building service systems, ensuring that the specified interior climate conditions and energy performance is met after the construction of the building.

      If BIM is applied to the design, the usage convenience of the building (comply with the planned functions) is high although the energy consumption is as low as possible. BIM provides dynamic building simulation which facilitates the building to function as a “real world” object and to verify the progress of vital quality parameters.

      BIM helps to strengthen the consistency, uniformity, and usability of forecasted energy use and energy cost results. Thus BIM provides an array of opportunities - comprehensive and precise energy estimates in advance in the design process, enhance life-cycle costing analysis, boost opportunities for measurement and verification throughout building occupation, and improve procedures for gathering lessons learned in high performance building. BIM based energy modeling can be applied to design and building operation, facilitating an overall cutback in energy consumption. BIM provides more traditional energy modeling practices, and discover opportunities to exercise BIM to support facilities management.

      BIM generates efficient basic information on a constant basis for the simulations to evaluate the emerging usage convenience and energy necessity in the quickest possible time span. The assessment of usage convenience will include the temperatures forming in rooms in summer, lighting levels with natural light, light glare, temperatures of enclosures, air flow owing to the interaction of ventilation and convection etc.

      The models utilized for building simulation are brought up to date all along specification of other models of building information. In the preliminary phase much information in the models is pre-conditional. With the development of the project, they will be substituted with actual choices. The role of comparison of various options is to demonstrate the impact of one or another pre-conditional decision on the development of the final result. In the phase of the preliminary model (preliminary design) the model contains adequate amount of details, facilitating to execute and submit calculations for checking of the completion of least obligations of energy efficiency, issuing of energy compliance, and will be the base task in the comprehensive design of exterior areas and building.

      In general the decisions taken all through the modeling of draft volumes have the greatest impact. As for instance the choices of compactness of the building, its orientation and facade apertures location and size have great impact on the interior climate as well as energy requirement. Therefore different decisions should be supported with sufficient thoroughness through building simulations and comparison options – justifying for example the use of smaller windows or thicker heat insulation layer in exterior enclosures.

      Advantage of BIM for energy modeling
      • Notify the decision-making procedure on the energy use entailments of diverse alternate design choices.
      • Create a representation or model of the performance of inexhaustible energy strategies, for example waste heat recovery, solar thermal systems, and solar electric systems.
      • Make a reduction in the expense of purchasing green power by making optimal energy performance of the building.
      • Analyze large-scale impacts for instance building configuration and orientation in conceptual design.
      • Describe the primary energy uses in schematic design realizing which loads (space heating, cooling, lighting, water heating, etc.) are most frequents and provides guidance on the building design phase to be targeted for energy savings.
      • A detailed energy model in design development provides parametric analyses to appraise alternate specifications and more fully understand the trade-offs between initial cost and life-cycle cost.
