Types of Drawings used in Construction

When drawings used in construction are put together and enlisted, they make a very large number. But we can study this topic by categorizing under main headings to make good understanding and confusions. The drawings used in construction can be categorized into:

1. Civil Drawings
2. Architectural Drawings
3. Structural Drawings
4. Electrical Drawings
5. Plumbing Drawings
6. Finishing Drawings

The types of drawings that comes under each are categorized and tabulated below

CIVIL	ARCHITECTURAL	STRUCTURAL	ELECTRICAL	PLUMBING	FINISHING

	Construction drawings/working drawings	Assembly Drawings

               Table.1: Major Classification of Drawings used in Construction Industry

1. Civil Drawings in Building Construction

As enlisted in the table-1 above, civil drawings include all the basic drawing details that provides a overall picture of the whole project. These drawings do not provide the specific details of every components of the building. The civil drawings has:

4. To impress and convince the Client
5. To assist the Building Contractor
6. To keep it as a Record of the Document
7. To make the Record of a Old Building

• Sketches or Concept Drawings
• Location Drawings or General Arrangement Drawings
• Floor Plans
• Elevation
• Section Drawings
• Construction Drawings or Working Drawings

3. Structural Drawings in Building Construction

Structural drawing is a type of engineering drawing that includes all set of plans that are used to built the structure. These drawings are developed by registered civil or structural engineers. They also take assistance from the architects.

The structural drawings communicate the complete in-depth design of all the elements of the structure. This is submitted to the government authority for review. These documents are included with the contract documents while bidding contractors.

Structural drawing includes:

• Design Drawings
• Engineering Drawing
• Component Drawing
• Production Drawing
• Scale Drawing
• Assembly Drawings

4. Electrical Drawings

Electrical drawings are also called as wiring diagrams. It is a technical drawing type that communicates the electrical systems or circuits. The drawings explain the design to the electricians or other workers who deal with installation and repair of electrical systems.

The electrical drawings include:

• Site plan with building location and external wiring
• Floor plan showing position of electrical systems
• Wiring diagrams that shows physical connections and the layout of the electrical system
• Schedules 
• Miscellaneous Information

5. Plumbing Drawings

Plumbing drawing in building construction are set of drawings that shows the layout of systems of pipes and piping arrangement that serve the process of carrying fresh water into the building and disposing the waste water from the building safely.
