A precise description of building construction Do you know how a building is developed today? I am sure you must not know anything about it, if you are not an architect and engineers. In fact nobody can understand the actual process and problems of building construction since it is a very intricate process which involves too many stakeholders such as surveyors, architects and engineers, general contractors and fabricators etc. All these people have to perform highly serious and result producing activities during project lifecycle. In the beginning when building owners come to know where they want to construct a building, they immediately have to hire surveyors who can evaluate the construction site. Once the site is effectively evaluated by surveyors and they convince the owners about its potential they can go ahead with the actual process. Now building owners are required to hire contractors who can finally take care of the entire construction project. These contractors who have to look after the entire construction of the building are known as general contractors. General contractors have to hire architects, structural engineers, MEP engineers, fabricators and rendering artists for execution of the project. First of all an architect is hired who develops the basic design of the building which is mainly its architecture. This design and referred by structural engineers and MEP engineers for developing remarkable design for their systems which can support the architecture of the building. Once conceptual design is developed for architecture, structure and MEP, general contractors can hire <a href=â&#x20AC;? http://www.teslacad.com.au/draftingservices.phpâ&#x20AC;?>drafting services</a> which can help in producing the conceptual design in papers. Once the conceptual design is presented in papers it can be easily provided for evaluation to different building stakeholders. That means the drawings which shows the design of the building can be distributed among architects, engineers, building owners and contractors during preconstruction so that the design and be effectively evaluated and understood by all the people involved in construction. After that 3D parametric BIM models are developed for each building discipline which further improves quality and worthiness of the design. After that the building construction can be started in the location.
