Building formwork is an essential component of the construction process. It is a temporary structure that is used to support and mold concrete into the desired shape and size. The formwork should be strong enough to bear the weight of the concrete and the workers who will be working on it. There are different classifications of building formwork, and in this article, we will discuss each of them in detail.

Classification of Building Formwork

There are different classifications of building formwork, and they are:

Based on Material Used

The first classification of building formwork is based on the material used to make the formwork. There are different materials used, such as:

Timber Formwork Timber formwork is the most commonly used formwork material. It is easy to work with, cost-effective, and readily available. Timber formwork is suitable for small projects and has a short life span.

Steel Formwork Steel formwork is more durable and stronger than timber formwork. It is used for large projects and has a longer life span. However, it is more expensive than timber formwork.

Aluminum Formwork

Aluminum formwork is lightweight, durable, and easy to use. It is suitable for high-rise buildings and projects with a tight deadline. However, it is more expensive than timber and steel formwork.

Based on Type of Construction

The second classification of building formwork is based on the type of construction. There are different types of construction, such as:

Conventional Formwork

Conventional formwork is the most common type of formwork used in construction. It is made from timber and is assembled on-site. Conventional formwork is suitable for small to medium-sized projects.

Engineered Formwork System

Engineered formwork system is a prefabricated formwork system that is made off-site and assembled on-site. It is suitable for large projects and is more expensive than conventional formwork.

Reusable Plastic Formwork

Reusable plastic formwork is a lightweight, durable, and eco-friendly alternative to timber formwork. It is suitable for small to medium-sized projects.

Based on the Method of Use

The third classification of building formwork is based on the method of use. There are different methods of use, such as:

Traditional Formwork

Traditional formwork is the most common method of use. It involves using timber or steel formwork and assembling it on-site. Traditional formwork is suitable for small to medium-sized projects.

Table Formwork

Table formwork is a type of formwork that is used for large slabs. It consists of a table-like structure with legs that can be adjusted to the desired height. Table formwork is suitable for large projects.

Tunnel Formwork

Tunnel formwork is a type of formwork that is used for the construction of walls and floors in a continuous pour. It is suitable for high-rise buildings and is faster than traditional formwork.
