On any kind of building projects it is very common that there will be some kind of changes made during the construction period due to the circumstances that might emerge on the site. Constructors do have their full draw construction made but they need to change it if necessary. As a result is it necessary to have a pencil sketch either before the construction work of during the construction process or when the construction is complete just to get an outline what will be the final result.
The main contractor can mark up changes to the final construction result drawings on the site itself using a red ink pen. Then the consultant team will make record drawings showing the final project. Construction is a general term people use for drawings which forms a part of the production information, later constructor shows it as a tender document and then as a contract document for the building construction works. These papers mean that they have legal documents and this forms a part of the agreement between the contractor and the employer.
The main purpose of this drawing is to provide a graphic representation of what the final project will look like. This drawing should be concise to avoid any kind of confusion. If the constructor wants to minimise any kind of delays or misunderstandings he needs to properly coordinate the drawings. If he can be good at this drawing then he will able to give details of the materials, techniques, standards and everything to carry out the work properly. This kind of drawings shows graphical representation which will indicate the arrangement of detailing, component, dimensions and many more such things. Theses drawings sometimes have some kind of information which sets out in specification. To avoid any kind of problem in the future it is better to refer to specification than duplicate information.
For a building project is necessary to draw the construction to scale either in a plan or in an elevation or section view. They have a set of standard architectural hatchings, signs and symbols which will allow anyone familiar with this to decipher and interpret it correctly. If any client wants a complete set of construction they he will get the floor plans, sections, elevations roofing systems and the section view. These together will provide a complete representation of a building. Many projects have major sections which will separate the trade drawings which include the work of a plumber, electricity connection and so on.
Next time when you go to talk or hire a constructor ask him to give a pencil sketch of the project. After that you can give your own inputs. Let the constructor know how you want your building to be. Tell him the colours you like or the materials you want. But the decision will be in his hands because constructor is someone who needs to make a building which can mingle with other buildings present in the neighbour. He needs to get permission for his work also from the local authorities.
