The building drawing of any structure is explained by a bunch of associated drawings that give the Builder a complete graphic description of each phase of the construction process. In some cases, a bunch of drawings starts by showing the path, boundaries, contours, & outstanding physical features of the construction site and its neighbor areas. Succeeding drawings give instructions for the excavation and disposition of existing ground; construction of the foundations and superstructure; installation of utilities, & whatever else is needed to complete the house design structure.
Construction drawings are sometimes referred to as working drawings or buiding drawings. They are used by all involved in a project to work on the actual building of the design. The main purpose of construction drawings (also called building plans, blueprints, or working drawings) is to show what is to be built, while the specifications focus on the materials, installation techniques, and quality standards. Most of the designers put their basic construction information in the drawings and use the spectacles to complex on materials, techniques, & standards to be met. Others pack their drawings with written notes that cover a many of the problems are frequently contained in the spectacles. In some Situations, you’ll find the same information in both places. If there is a spectacles between the specs and drawing, the spectacles generally override the plans, at least legally.

RCC drawing shows the layout of steel reinforcing bars in the concrete namely column centre line, footing layout, footing schedule, Typical beam framing layout, Plinth beam layout , Slab layout, Slab schedules column schedule, typical Staircase drawings. They outline the size and types of materials to be used, as well as the general demands for connections.
These drawings communicate the house plan design of buildings structure to building authority to review. They also become part of the contract documents which guide contractors in detailing, fabricating and installing parts of structure.
These drawings plays crucial role in the success of any structural construction and bidding process It provides a platform for planning and estimating cost for each phase of construction.
Structural drafter is responsible for producing working drawings that clearly describes the schedule and material involved for each phase of construction.
To generate accurate construction drawings the drafter must have thorough domain expertise knowledge of local building codes and relevant industry experience.
