What Is Formwork?
Important Point
The construction of a concrete building requires formwork to support the slabs (horizontal formwork) as well as columns and walls (vertical formwork).
The terms concrete formwork and concrete form carry the same meaning and are used interchangeably in this book.
Formwork is defined as a temporary structure whose purpose is to provide support and containment for fresh concrete until it can support itself. It moulds the concrete to the desired shape and size and controls its position and alignment.
Concrete forms are engineered structures that are required to support loads such as fresh concrete, construction materials, equipment, workers, various impacts, and sometimes wind. The forums must support all the applied loads without collapse or excessive deflection.

What Is Shuttering?
Vertical formwork is known as shuttering. Formwork for columns, retaining walls, footings are known as shuttering.
It is a part of formwork, which is quite popular now a days & constructed on sites by using Steel & plywood. formwork that supports vertical arrangement is known as shuttering.
It acts as moulds for pouring concretes, which supports the surface vertically during the construction process for instance column, beam, slab, wall sides & so on.
Moulds can be temporary or permanent wherein concrete or similar material is poured & formed. During shuttering, it is advisable to use waterproof & good quality plywood. In concrete construction methodology, the falsework supports the shuttering moulds.
Shuttering work is a vertical temporary arrangement that is arranged to bring concrete in the desired shape.

What Is Scaffolding?
Scaffolding is a temporary platform used to lift, support, and supply materials during a construction process for the repair or cleaning of a structure.
It is installed before construction or maintenance work begins. Therefore, whatever the size of a building, scaffolding will always be necessary.
This is done to ensure the safety of workers while the building is being maintained or constructed. In addition, it also provides some degree of support for a standing structure during the construction phase.
Scaffolding is made of wood or steel. It must be stable and strong to support workers and other construction materials placed on it.
Types of Scaffolding
- Single Scaffolding.
- Double Scaffolding.
- Cantilever Scaffolding.
- Suspended Scaffolding.
- Trestle Scaffolding.
- Steel Scaffolding.
- Patented Scaffolding.
- Wooden Gantries Scaffolding.

Shuttering and Centering
Centering and shuttering are both formworks. Centering term is used when the formwork is horizontal like slab, floor beam, etc. Shuttering term is used when the formwork is vertical as in column, footing, retaining wall, etc. Steel and timber planks are commonly used materials for centering and shuttering.
What Is Centering in Construction?
Centering is essential for creating the desired shape and supporting the weight of the construction materials until they are set and hardened. It provides stability and ensures that the structure maintains its shape during the construction process. Centering is commonly used in the construction of bridges, tunnels, domes, and other structures that involve curved or arched elements.
What Is Shuttering?
Shuttering, also known as formwork, refers to the temporary structure or mold that is used to shape and support freshly poured concrete or other construction materials until they set and harden. It provides the desired form, containment, and support during the construction process.
What Is Centering and Shuttering in Construction?
Centering is used to support horizontal members. Hence, formwork for floor beams and slabs is known as centering. Shuttering is used to support vertical members. Hence, formwork for columns, footings, or retaining walls is known as shuttering.
What Is Formwork in Concrete?
formwork, Mold used to form concrete into structural shapes (beams, columns, slabs, shells) for building. Formwork can be of timber, steel, plastic, or fiberglass.
What Is Concrete Formwork?
Formwork molds the concrete to the desired size and shape, and controls its position and alignment. It is a temporary structure that supports its own weight and the freshly placed concrete, as well as construction live loads including materials, equipment, and workers.
