Plans are like a set of drawings or two-dimensional diagrams that are used to narrate a place or object or to communicate building or fabrication instructions which are drawn or printed on paper and can take the form of a digital file.
Planning are generally made for different technical purposes like architecture, engineering or construction etc. and those capture all the geometric features of a site, building, product or component in an accurate and clear way so that it can display a clear information to the builder or manufacturer to help in design.
Generally this process of making plans and producing them is known as technical drawing and a working drawing is a kind of technical drawing where documentation has to be done to build any engineering product or architecture such as civil, architectural, structural, mechanical, electrical and plumbing etc. In the same way there is some software that helps to plan the models for building purpose or designing in other way such as BIM describes the process of creating and managing digital information about a building or other facility like bridge, highway, tunnel etc. and many more. BIM ensures that actual information should be created in a right format at the appropriate time so that better decisions can be taken in throughout the design, construction and operation of built assets.
At the beginning of a project, the BIM is known as Project Information model might include previous information like site reviews, condition reviews, information about previous services and many more and all those information should be generated from a previous Asset Information Model or Aim to operate and maintain a built asset.
A design intent model is developed in the time of design stages going in a project and it gets more detailed with the growth of the project and at last it will become a Virtual Construction Model with all other objects in the model to be manufactures, installed or constructed.
Design Drawings: they are used to develop and communicate ideas about a developing design and in the beginning stage of designing them only demonstrate to the client the capacity of a particular design team to grasp the design.
These designs are used in developing and communicating the detail, examine potential sites and assess options and develop the approved idea into a consistent and co-ordinate design and communicate the developed design to the local planning authority, contractors and suppliers.
Besides that it also keeps the track of the completed construction and constant changes in completing the construction project. But it is also true that some of these are not always known as design drawings as sometimes they has not started well or completed early. But all of them have some things of investigation or development of the design or sometimes they are good for nothing.
So these design drawings can be categorized as:
• Feasibility studies.
• Option appraisals.
• Concept drawings.
• Detailed or developed design.
• Technical design.
• Tender drawings.
• Shop, installation and construction drawings.
Design drawings are developed in a detailed way from block and massing drawings, sketches to detailed technical drawings etc. but while developing it are important to know the purpose and about the information the designs can narrate through them. They must determine their actual format, size, scale and every little detail that will be useful for the drawings suppliers to use in fabrication. These drawings can be prepared by architects, technicians, structural engineers, civil engineers and so on other different practitioners; but they must be carefully integrated and co-ordinated to give security about the right level of design in all the elements. These drawings has been revolutionized at first by CAD and then by BIM.
