Construction Drawings - Everything You Need to Know

Construction drawings are a fundamental tool in the construction industry. They are used to visualise and communicate how a building or facility will be constructed, enabling all parties involved to follow a common plan and ensure that the work is carried out correctly and efficiently. Construction drawings are essential for all phases of a construction project – from design and planning to construction and finally maintenance.

What is a construction drawing?

A construction drawing is a technical illustration that describes the design and construction of a building. It may include details of building materials, dimensions, and structural elements. The drawings serve as a visual instruction that guides construction workers, engineers, and architects in their work.

Construction drawings can be physical documents or digital files, depending on the technology and working method used in the project. With the advancement of digitalisation, many drawings have now become part of BIM (Building Information Modelling), where information about the construction project is collected in a common digital system. This makes it easier to collaborate between different actors, Key individuals and ensures that all information is updated and available in real time.

Different types of construction drawings

There are several different types of construction drawings, depending on what area of the construction process they focus on. Here are some of the most common types:

• Structural Drawings: These drawings focus on the load-bearing parts of a building, such as the foundation, walls, roof, beams, and columns. They specify materials, dimensions, and how the various parts will be connected to ensure stability and durability. Structural drawings are essential for the building to be safe and able to withstand loads from weather, people, and objects.
• Reinforcement drawings: These drawings show how to reinforce the load-bearing parts of the building. They indicate the number, dimensions and c/c measurement of the reinforcement. These can be plan and detail drawings. The plans show the overview and how the slabs are reinforced, the detail drawings show the reinforcement in minute detail at tricky connections, beams and column sections.
• Detail Drawings: These drawings are more focused on specific parts of the building, such as doors, windows, stairs, or other special features. Detail drawings are used to provide carefully specified instructions for construction workers working on these specific details.

Digitalisation and BIM

With the help of digitisation and Building Information Modelling (BIM), construction drawings have become more accurate and efficient. BIM enables all parties involved to work with a common model that contains all relevant information about the construction project.

By incorporating construction drawings into a BIM model, architects, engineers, and construction workers can collaborate more effectively, make changes in real-time, and quickly identify potential problems before construction begins.

Benefits of working with digital construction drawings

Using digital engineering drawings instead of traditional paper drawings has many advantages. First, it reduces the risk of errors because all parties have access to the same, up-to-date information. It also saves time and money by making it easier to make changes and adjustments without having to create new paper drawings.

BIM also enables the creation of more sustainable buildings, as it provides a better overview of the building's life cycle. By analysing and simulating the construction process and the use of the building, more informed decisions can be made about material selection, energy efficiency and operating costs.

With Symetri as your partner, you get access to tailor-made digital solutions for BIM, product design and lifecycle management, allowing you to work smarter and streamline the construction process. Symetri offers both software and expert BIM consulting services to ensure your construction process is as efficient and future-proof as possible.

By using digital construction drawings and BIM technology, the construction industry can more easily manage complex projects and ensure that all parties are working towards the same goal. This makes it possible to build more sustainably, faster and with higher quality.
