What is a construction drawing?

It is a graphical representation of what will be built, how it will be laid out, the components, framework, and dimensions. There is a construction drawing highlighting the details of every aspect of a construction project.

Construction Drawings including each of its subtypes are helpful to different groups of workforce assigned with doing or overlooking the various tasks that make up a construction project.

How are construction drawings made?

Rarely are construction plans drawn by hand anymore. They are either sketched and rendered using computer-aided drafting such as computer-aided design (CAD) software. And in recent times, Building Information Modeling (BIM) software has made it easy to render and visualize in detail the virtual construction models (VCM).

Top 46 most common types of Construction drawings use regularly in construction industries.

Architectural Drawings

Architectural Drawings are drawing work that is used in building drawings to depict the dimensions, depth, and layout of the actual building, prior to beginning the construction. Architectural Drawings act as a blueprint construction, drawn to scale, to help the engineers visualize the project.

Various types of Architectural Drawings commonly used are:

1. Block Plan

This drawing gives a layout of the site or the buildings in the surrounding area, laid out on a map drawn to scale.

• It gives a firsthand idea of the roads, boundaries and other such details that are necessary to understand where your construction site lies.
• It helps the person dealing with your construction plan or project request to understand what and where you are proposing it and help you out with it too.
• Block plans are made in relation to Ordnance Survey Maps and the recommended scales used are 1:2500, 1:1250 or 1:500.
  
  

2. Foundation plan 

Not to be mistaken for just the ground or basement floor plan. Foundation Plans are drawing work to render any of the floors of the building being constructed. They help visualize the dimension, size, shape, height and configuration of rooms/stairs/landings with each other.

3. Floor plans

In-depth rendering of the layout of the rooms for each floor. It describes in 2D the orientation of rooms and components to each other. Floor plans may or may not be utilized in commercial or non-commercial building projects, but it is necessarily still made as part of the drawing work.

4. Sectional Drawings

These are drawings that depict a part or whole of the framework in sliced form. It helps understand the measurements of various building components with each other, the materials used in the construction of those components, the height, depth, and hollowness, etc.

5. Elevation Drawings 

These architectural drawings offer an aesthetic overview of the various components of the building such as columns, windows, and doorframes. It also helps understand the relative surface, internal markings, and relative height of these different components to each other.

6. Site Plan 

A site plan is a detailed drawing that shows the entire construction site with property boundaries, existing structures, proposed new building locations, site grading/topography, and other site features like landscaping, parking areas, utilities, etc.

7. Isometric Drawing

An isometric drawing is a type of 3D parallel projection used to represent objects pictorially. It shows three sides of an object with the vertical lines projecting at a 30-degree angle and the horizontal lines projecting at a 30-degree angle.

8. Axonometric Drawings

Axonometric drawings are types of 3D parallel projections that show an object in an oblique/angled view. They include isometric, dimetric, and trimetric drawings depending on the exact angle used for the horizontal and vertical lines.

9. Presentation Drawings

Presentation drawings are highly detailed renderings or 3D models used to communicate and visualize the design intent for clients, stakeholders, and approving authorities. They showcase the appearance, materials, and aesthetic qualities of the project.

10. Survey Drawings
