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.
