Building Information Modeling for Building Lifecycle Management

The primary difference in the Parametric Modelling and BIM is the ability of BIM to store data related to the specifations of the built structure, schedule and derive cost estimate. Also one BIM model can be shared and two or more people simultaneously work on one model through networt computer or cloud.

A short history of Building Information Modeling, the software which has disrupted traditional methods of representation and collaboration in architecture. Building Information Modeling is a term which became ubiquitous in the design and construction fields across the last 20 years, but where did it come from? The narrative is rich and complex with players from the Across the world competing to make the perfect architectural software solution to interrupt 2 Dimensional CAD workflows. The advantages of an architectural design model linked to a relational database have been shown to be extremely valuable, with builders, Architects, Civil Engineers becoming the primary drivers of BIM technology in the recent years of progress in the technology.

Just what exactly is BIM? The question frequently arises, for the purposes of the article, BIM software must be able to represent both the physical and intrinsic properties of a building as an object oriented model tied to a database. The user can see and interact with the model in 3 dimensional perspectives in addition to an orthogonal two-dimensional plane, sections and elevation views of the model. As the model is developed, all other drawings inside the project would be correspondingly adjusted. A Building Information Model might be designed in a software that's not strictly speaking, parametric and where all info and geometry is explicitly defined however this will be cumbersome.

A Parametric building modeler will enable the user to create constraints like the height, width, depth in 3D space, which can be tied into the height of specified set of walls and parametrically adjusted, creating a dynamic database model which is tied to geometry. This development answered a need in the architectural industry to be capable to change drawings on several scales and across fragmented drawing sheets. The amount of hours which are needed for the creation of drawings has diminished steadily with time. The improvement in productivity has risen in concert with computer technology which has automated tedious tasks in all disciplines.

The primary difference in the Parametric Modelling and BIM is the ability of BIM to store data related to the specifations of the built structure, schedule and derive cost estimate. Also one BIM model can be shared and two or more people simultaneously work on one model through networt computer or cloud. The latest trends in the BIM further extend the concept of BIM into facility management where, the ERP softwares may use 3D BIM interface, store the important information like insurance, warranties in model, quantify the Asset Price and depreciation it will recieve and record all the maintenance records of Building Facilties in one BIM model. which then would be considered as building record model. Such an integration would helf the facility manager to reduce the turnaround times, reduce the maintenance cost, and increase the building performance. So use of the BIM is not only in Building Design and Construction, but also in Maintenance, Operation and Building Lifecycle.

Which BIM Software is Ideal, Although there are many softwares available which are developed for general purpose building , some are developed for specialised building type Example Residential, Industrial etc. Also the BIM software developer has tyllpically has two challenges , that the interface should be user friendly but also all the functions and complexities associated with the BIM modelling should be addressed, so that maximum data can be processed. The Autodesk , Bentley Microstation are few of the examples. I will cover saperate articles for review top 10 BIM softwares according to user experience.

Today when we retrospect the progress of BIM technology, we can conclude that BIM is the one of the essential tool for designers, managers in a collaborative workspace, and further more and more organisations will aknowledge it as an essentail tool for building lifecycle management.

Friends, the opinion mentioned in this post are my own but you may differ with me. I only started this topic, however I expect more of your participation to start a discussion. I would appreciate if you share your opinion in the below comment box.

thanks and regards,
