Planning is imperative before starting any construction project. It provides a comprehensive overview of the building in detail. However, different types of construction drawings are being used for that purpose today.
These drawings play a crucial role in setting the benchmark of the building project. In addition, they also assure compliance with the construction work standards. The drawings not only help get the project approved, but they also provide technical details.
In this article, we’ll discuss the 11 most common types of drawings used in construction.
What Is A Construction Drawing?
A construction drawing shows the structure, components, and dimensions of the project, as well as the framework for it. In short, the drawing of the building highlights the crucial details of all aspects of the work. A specification document usually accompanies these drawings.
However, the specification details the standards, techniques, and materials engineers should consider to construct the building. Additionally, the construction drawing comprises information from other professionals, like structural experts and fire safety.
Top 11 Common Types Of Construction Drawings
1. Site plan
The site plan drawings are nothing but an aerial view of the building site. Also, they comprise the primary building and its surrounding constructions. Architects use these drawings to improve buildings and determine the scope of many construction activities.
Aside from this, it also helps figure out the topography of the building, like pavements.
2. Block Plan
A block plan depicts the wider area surrounding a building under construction. These construction shop drawings include the roads, adjoining buildings, boundaries, etc. Also, block plan drawings are shown in scales. It indicates that they cover a broad area.
Moreover, the recommended scales for the block plan are 1:500, 1:1250, or 1:2500.
3. Architectural Drawings
Architectural drawings offer an all-inclusive building design view. Besides, designers and architects rely on 2D and 3D modeling to communicate their ideas more effectively. Traditionally, these drawings were drafted in ink on paper, requiring costly hand delivery.
However, by embracing digital ecosystems, we can gain efficiency and minimize costs.
4. Production Drawings
Production drawings are advantageous for suppliers and manufacturers. These construction drawing lines illustrate the whole manufacturing process, product finishes, materials, and dimensions. These drawings serve as reference documents.
With the help of production drawings, architects can figure out how to meet deadlines.
5. Structural Drawings
We can term a structural drawing a civil engineering drawing. Also, these drawings work as the structural design guide for the on-site engineers and workers. The common types of these drawings are beam layouts, column layouts, general notes, and others.
These drawings specify the types of materials and the size to be used in the building.
6. Electrical drawings
Most commercial or residential building drawings require a detailed outline of the number of lights, power outlets, fixtures, etc. Besides, they also comprise the wiring pattern. Here are some typical details included in the building’s electrical drawings:
- Cable tray layout
- Dangerous areas classifications
- Earthing layout
- Light fixture layout
- Lighting protection system
- Generator and other essential equipment
7. Section drawings
As the name indicates, section drawings demonstrate the structure in sections. In addition, these drawings can help create the construction worker drawing as well. It shows the materials that engineers will use in the construction.
So, if you want to determine the primary structures following the surrounding structures, section drawings are worthwhile.
8. Plumbing Drawings
Plumbing is another crucial component of the commercial or residential construction drawing. So, engineers use plumbing drawings to determine where the plumbing parts need to be set up. However, these types of building drawings include the following:
- Outlet points – tanks, sinks, taps, etc.
- Pipes materials
- Pipes – internal pipes, drainage pipes, water pipes
9. HVAC Drawings
HVAC drawings are also termed mechanical drawings. Besides, they provide an inclusive framework for ventilation and heating systems in the building.
Drawings can also help design the construction draw schedule. It typically outlines when the builders will receive their payments. If we talk more about HVAC drawings, builders must remember to use these drawings in the construction process accordingly.
10. Firefighting Drawings
Firefighting drawings are a comprehensive representation of different fire protection systems in two dimensions. Additionally, these drawings depict the dimensions, number, and location of firefighting system elements, such as heat detectors, fire alarms, etc.
In today’s complicated construction systems, it is paramount to ensure the safety of the design. In short, firefighting drawings are a crucial component of the building’s blueprint drawings. They allocate points for sandbags, water outlets, fire hoses, and many more.
11. Finishing Drawings
Finishing drawings comprise finer and more highly detailed building plans. However, architects require these drawings for the functional and aesthetic value of the building. Aside from this, these types of drawings include the following details:
- Floor patterns
- False ceilings
- Designs and motifs
- Tile patterns
- Paint textures and colors
Each construction drawing mentioned above has unique advantages. And engineers can use them at different stages of the building process lifecycle. No matter if it is the conceptual designing stage or the construction project handover. All these drawings play a critical role in executing and delivering the construction process more smoothly.
What drawings do you need for construction?
Some common types of drawings needed for the construction include the following:
- Electrical drawings
- Architectural drawings
- Sanitary and plumbing drawings
- Structural drawings
- Finishing drawings
Why are as-built drawings important in construction?
As-built drawings are essential for contractors and subcontractors in the construction industry. So, if the project stakeholders are equipped well with all these drawings. Then, they can have a better idea of how the building project was performed.
What is the main purpose of built drawing?
The main purpose of built drawings is to determine how the contractors and subcontractors built the project. In addition to this, it also helps identify any modifications made during construction.
What is the purpose of construction drawings and specifications?
The primary purpose of construction drawings and specifications is to provide the project’s graphical representation. Coordination and conciseness are necessary, however, to avoid ambiguity or confusion. Contractors can quickly minimize misunderstandings and delays by coordinating the drawings more appropriately.
