To carry out any building project, a set of architectural drawings created by architects is required on the construction site to define the production specifics into tender documents, such as the materials to be utilised, extremely exact proportions, and so on. Detail architectural floor plans, elevations, or sections are popular types of construction drawings.
What is Construction Drawing?
Construction drawings are architectural drawings supplied by the architect to express his concept, ideas, construction details, and other specifications that are required on the job site. This is to make sure that the contractors will implement the design as specified. It also serves as a record for the client's current building.
Types of Construction Drawings:
On the building site, many blueprints are needed to complete each specific construction activity. Construction drawings of several forms may be necessary to specify each construction detail to the contractor, which may include the drawings defined below:
- Working Drawing Plans: These are the drawings that depict the floor plans from the top, specifying the location of the doors, windows, and other interior floor elements, such as the furniture layout.
- Elevations: Elevations determine the outside perspectives of the buildings from both sides. It specifies how a structure will seem from the outside once construction is completed.
- Setting out Plans: These include the dimensions of every minute element on the plans. It is very useful for determining the distance between items. Any tiny error on the layout plan can result in a different design on the site.
- Sections: Sections are formed when we cut a building down. It illustrates a cross-section of each structural component of the structure, including the walls, ceiling, staircases, doors, and window apertures, as well as all other key architectural parts.
- Plumbing and Sanitation Plans: These drawings are used to specify the location of faucets and taps in wet areas such as the kitchen and bathrooms.
- Structural Drawings: These are created by a structural engineer based on the drawings supplied by the architect to define the specification of the reinforcements and other structural elements to assure the building structure's requisite strength.
- Electrical Plans: These designs aid in defining the location of all electrical equipment and switches. They also describe internal wiring connections to assist the electrician in setting out the wiring in individual locations.
- HVAC Drawings: In the case of a centrally placed ventilation system, the architect allots a detailed set of HVAC drawings to indicate the location of apertures and ducts in the building.
- Typical Construction Details: These are the most significant set of drawings to utilise on the job site since they define every single construction detail, allowing the contractor to control the construction on the job site.
The architectural drawings mentioned above are different in nature. However, they must be coordinated with one another to avoid any type of collision throughout the construction process. The smallest flaws in the above-mentioned drawings may result in a poor execution of the approved design and even larger faults.
Why Construction Drawing Is So Important?
Sometimes, when the building process of a project needs to speed up, architects may overlook the detailing phase of the project on the plans. However, due to insufficient instructions defined by the building plans, this may cause a further delay in the construction process and an increase in the expected budget. This will necessitate extra time spent on the construction site defining the criteria for proper execution.
The significance of construction drawings is found in the proper and smooth execution of the construction process on the job site. If these drawings provide insufficient information, design execution may be inhibited. To avoid future disasters and delays on the building site, each construction design must be scrutinised and verified by the concerned architecture firm or concultancy as well as the other technical professionals involved in the development of respective drawings before being assigned on the site.
