An inclusive account of conventional design development process! In the conventional building process various effective and potential techniques and technologies have been adopted by design and construction professionals for developing appropriate building design. Design development phase remains one of the most instrumental parts of preconstruction process wherein an idea is developed from its conceptual phase to a full-fledged building design. Two very crucial technologies are implemented by AEC professionals in design development process which include CAD and BIM. CAD is used during drafting process wherein drafters develop CAD drawings for showing the design of multidiscipline building trades such as architecture, structure and MEP. All kinds of technical drawings such as architectural, structural or MEP are now generated in digital forms that means CAD technology is absolutely responsible for digitalizing drafting process.
Detailed plans, drawings and layouts etc are created by competent drafters with the support of AutoCAD for different building disciplines. AutoCAD helps drafters in maintaining high accuracy in shop drawing and other kinds of technical drawings that are generated by drafters during drafting process. Be it architectural drawings, structural drawings or MEP drawings all of them are equally important for accomplishing
modeling process that is carried out with the assistance of BIM technology. This means that another important technology that is used in design development process is Building Information Modeling. BIM software is used for the first time in modeling process. Modeling process is nothing but the process of developing 3D models which helps design and construction professionals in representing physical as well as functional attributes of the yet to be constructed building. The name of BIM software which is used worldwide for executing modeling services is Revit. Revit is crafted by a highly prominent American software manufacturing company Autodesk which as developed multiple building design software such as AutoCAD, Navisworks and 3ds Max etc. All of which are used by design and construction professionals in preconstruction phase for diverse reasons. High end building design is created in Revit which allow all its design members to collaborate with each other for acquiring and distributing construction related information. Effective distribution of information helps in effective development of 3D models as information stands at the heart of design development process in Revit. When models are constructed in Revit every member of design team remains aware of progress made in the model as they keep monitoring the process through a central model which can be accessed by anyone with the help of Revit server. The individual models on which design members work are the copy of a central model which can be accessed by them anytime. This transparent design development process helps in developing effective BIM models which represent the design of different building disciplines.
