Understand what construction drawings (construction design documents) include

In the architecture and construction industry, construction drawing Not only are they dry technical lines, but they are also the “soul”, the core communication language between the design office and the construction team at the site. This article will help homeowners who are building a house have complete information about what construction drawings include, and a complete list of drawings in a standard architectural profile.

What is a construction drawing (construction design document)?

Construction drawings is a term referring to a collection of construction technical documents, created by architects/engineers through design software to serve the construction work of projects. Construction drawings are often known by a number of similar terms such as "architectural documents", "construction design documents" or "construction technical drawings".

There are two main types of construction drawings: Construction design drawings and licensing drawings. These two types will have different drawing list components. Construction design drawings are used directly on the construction site for workers and supervisors to use during the construction process, licensing drawings are used to send to the competent authority attached to the licensing procedure.

These drawings describe in detail all information about: Design, dimensions, materials, structural details and the necessary parameters to construct a project. This is an indispensable guideline for every project, big or small, so that the construction team on site can clearly understand the construction method..

The importance of construction drawings in every project

The importance of construction drawing in projects build a house package is expressed through many essential aspects as follows:

• Common communication language: Acting as a communication bridge, ensuring a unified understanding between investors, architects, engineers, contractors and construction teams. The clarity of the drawings helps to accurately convey design ideas to customers and stakeholders.
• Precise construction foundation: Provide details on dimensions, locations, materials and processes, helping construction run smoothly, minimizing errors and risks.
• Quality control tools: It is the basis for monitoring, checking and ensuring that the project complies with the design, meets technical standards and committed quality.
• Important legal basis: Is the official construction document, recording technical and design requirements, serving the acceptance, payment and resolution of arising problems (if any). It is also a mandatory document to be able to obtain a construction permit, and is also the basis for completion.
• Optimizing costs and progress: Accurate drawings help estimate costs effectively, limit unexpected costs and ensure project progress, bringing practical economic benefits.

Can say, construction drawing is the "DNA" of the project, determining the shape, function and feasibility of the project.

What drawings does an architectural design file include?

A complete set of architectural design documents usually includes many types of construction drawing Specialized:

1. 3D perspective design:
   • Purpose: Showing the entire exterior and outside space of the house helps customers easily visualize the project when completed. Standard 3D perspective shows the closest similarity to the actual house after construction, including elements such as materials, light, shape, color, landscape, etc.
   • Include: All views fully represent the necessary angles of the house.
2. Architectural Technical Drawings:
   • Purpose: Expresses the overall design concept, spatial layout, shape, size and aesthetics of the project.
   • Include: Functional floor plans, elevations, architectural sections. Detailed drawings of structural components of the house's architecture. Detailed drawings of areas such as steps, lobby, fences, stairs, etc.
3. Structural Drawings:
   • Purpose: Focus on load-bearing components (foundation, columns, beams, floors), ensuring stability, safety and sustainability for the entire project.
   • Include: Details of foundation, columns, beams, floors, reinforcement arrangement.
4. Mechanical and Electrical Drawings (MEP – Mechanical, Electrical, Plumbing):
   • Purpose: Detailed description of mechanical systems (air conditioning, ventilation), electrical systems (lighting, sockets, low voltage) and water supply and drainage systems.
   • Include: Schematic diagram, layout drawing of equipment, lines, pipes.
5. Landscape Drawings (If Any):
   • Purpose: Design of exterior space, garden, landscape, contributing to increasing the aesthetics and harmony of the project.
   • Include: 3D perspective design of landscape garden, technical construction drawings for landscape garden.
6. Other types of drawings:
   • Drawing construction permit: Serving legal proceedings.
   • Completion drawing: Record actual changes from the original design after construction.
   • Detail Drawings: Zoom in on complex structures, special joints.

At XHOME Saigon, we not only ensure close coordination between design disciplines, but also apply BIM process to synchronize architecture, structure and MEP from the beginning – helping to precisely control drawings, limit conflicts and optimize construction costs.

List of drawings in XHOME Saigon's house construction design documents

To best understand what you are paying for home design and architectural design services and what you get in return. XHOME Saigon would like to share with customers some examples of standard construction drawing systems in a complete architectural profile.

1. 2D architectural technical drawings

Below is a complete drawing list of an architectural technical design file, ready for construction. This is a real neoclassical villa project that XHOME Saigon has implemented. The list includes 54 parts with 185 pages.

Note: Depending on the type of project, some drawings may be added or removed to most clearly demonstrate the construction techniques.

2. Example of architectural 3D perspective

Perspective helps customers visualize the house, perspective rendering to meet standards requires adjustment of light, materials and color ratio in the design to best represent the design plan.

3. MEP Drawings

Below is a list of example MEP drawings of a block of houses in a housing complex implemented by XHOME Saigon in 2024 (the owner has been renamed).

4. Structural drawings

The list of structural drawings includes the following components:

Example of structural drawing components currently applied in the current XHOME Saigon structural profile. Note that this is a partial representation of only 33 items, not fully representative of a XHOME Saigon structural profile implemented in 2024.

Main components contained in a detailed construction drawing sheet

To convey information effectively, each construction drawing must have the following components:

• Title Block: Contains basic project information, drawing name, number, scale, designer, drafter, inspector, date, and legal information.
• Scale: The ratio between the size on the drawing and the actual size helps readers visualize the project correctly.
• Dimensions: Numbers indicate length, width, height, and distance of components and details.
• Symbols and Legends: Use standard graphic symbols to represent materials, equipment, and conventions. The legend explains what these symbols mean.
• Line Types and Layers: Different types of lines (solid, thin, dashed, dotted, etc.) with different thicknesses represent different objects and meanings.
• Notes and Schedules: Provide additional information, technical instructions, material and equipment statistics.

What standards do construction drawings comply with?

It is not natural that parameters appear in architectural drawings, architects/ engineers need to comply with mandatory standards to ensure accuracy, uniformity and understandability of construction drawing, For example:

• Vietnam Standard (TCVN): Is a mandatory system of regulations applied in Vietnam, for example: TCVN 6083:2012 (presentation principles), TCVN 5571:2012 (title frame), TCVN 9:1985 (dimension recording).
• International Standards (ISO, ASTM, ACI): Widely used worldwide, especially important for projects with international elements, ensuring global readability and quality.

XHOME Saigon always updates and strictly adheres to current standards, ensuring the highest quality of design documents.

Drawings are important but also cause difficulties for homeowners.

• Complexity: Requires specialized knowledge and experience.
• Inconsistency, error: Can lead to misunderstandings and wrong construction. (Causes include choosing an unprofessional design unit and lacking internal processes leading to poor quality documents)
• Difficult to visualize 3D space from 2D drawings: Especially for non-professionals.
