Definition:
Proposed drawings are created at the initial planning stage based on client requirements, available funds, lot size, and the building's intended purpose.

Features:

• Developed by the architect after discussions with the client.
  
  

• Includes plans and elevations on a small scale (e.g., 1/8 or 1/16).
  
  

• Sectional views are generally not required.
  
  

• Often made visually appealing with colors and perspective views.
  
  

• Helps in finalizing the design before official approval.

Definition:
Submission drawings are official documents required for getting approval from development authorities before construction begins.

Features:

• Includes site plan, location plan, and building plans (ground floor, first floor, etc.).
  
  

• Contains basic elevations and sectional views with only key heights and measurements.
  
  

• Shows sewage line, road connections, and neighboring plots.
  
  

• Windows and doors are marked as D1, D2 (doors) and W1, W2 (windows).
  
  

• A Schedule of Openings (table listing door/window sizes) is provided.
  
  

• A Schedule of Areas (table listing total plot area, covered area, etc.) is included.
  
  

• Must have owner’s name, address, and architect’s signature.
  
  

• Some authorities may require a Stability Certificate.
  
  

• Once approved, construction can begin.

Definition:
Working drawings provide detailed technical information required for the actual construction process. They are used on-site by engineers and workers.

Types of Working Drawings:

1. Architectural Working Drawings
   
   

   • Includes detailed plans, elevations, and foundation plans.
     
     

   • Contains information about doors, windows, plumbing, and electrical fittings.
     
     

   • More than one elevation is often drawn to represent different views.
     
     

2. Structural Working Drawings
   
   

   • Includes the foundation plan and reinforcement details.
     
     

   • Covers plumbing and electrical layouts.
     
     

   • Specifies bathroom, kitchen, and furniture placements.
     
     

   • Essential for engineers to execute construction according to design.
     
     

Definition:
Completion drawings (also known as "as-built drawings") are created after construction is completed. They reflect any changes made during the construction process.

Features:

• Includes the final version of the building’s layout.
  
  

• Any modifications in room sizes, door/window positions, or material usage are documented.
  
  

• Submitted to authorities to obtain a Completion Certificate.
  
  

• The owner can legally occupy the building only after approval.

Proposed Drawing

Initial design planning

Plans & elevations on a small scale, no sections

Submission Drawing

Approval from authorities

Includes site plan, location plan, basic elevations, schedule of openings & areas

Working Drawing

Used for actual construction

Includes foundation plans, reinforcement details, plumbing, and electrical layouts

Completion Drawing

Reflects final construction

Documents changes made during construction, required for Completion Certificate

Conclusion

Each type of drawing plays a vital role in the construction process. Proposed drawings help finalize designs, submission drawings ensure legal approval, working drawings guide actual construction, and completion drawings provide a final record of the built structure. Understanding these drawings is essential for architects, engineers, and construction professionals.
