What Is The Difference Between Formwork And Scaffolding? 5 Points You Must Note To Understand The Basics.
Scaffolding and formwork are widely utilized in the building industry for a variety of purposes.
Formwork is used by construction teams to mold wet cement or keep it in place until it solidifies
to the desired form. It is described as temporary or permanent casings or molds that secure the
concrete until it dries enough to bear its own weight. Scaffolding is distinct from formwork in that
it is a temporary structure used as a working station to assist people during building, upkeep, or
repair work and allows employees to climb heights they would not be able to reach otherwise.
Materials used in scaffolding and formwork are different
Scaffolding is a modular structure made out of panels, tubes and tube couplers of wood,
bamboo or metal. Its form might be simple or sophisticated, but it is always built with care since
it accommodates large groups of individuals moving about. It must be safe and robust since it is
used for a number of reasons, including painting the exteriors of buildings, functioning as a
makeshift bridge or pathway, and bracing props. It provides security by providing handrails,
serving as a ramp, or acting as a leveling or supporting structure for a construction site.It allows
employees to freely move around the structures by providing access to rooftops and ledges.
Formwork can be made from plywood, wood, plain concrete, reinforced concrete, and steel
combined with wood. Given the numerous applications, formwork and scaffolding are necessary
for the building sector.
Formwork and scaffolding have separate usages
Formwork and scaffolding are used for wholly separate reasons and have entirely different
needs. Scaffolding must be simple to erect, simple to deconstruct, and easy to move.
Scaffolding platforms must have large enough surfaces for individuals to freely walk and
conveniently handle and transfer goods. The structure must be sturdy enough to withstand
climatic changes and not tremble, distort, or tilt over time. Scaffolds are often dependent
constructions; they are typically attached to a structure or steelwork using ties for support.
Formwork system, on the other hand, is classified as recyclable plastic, solid stay-in-place
structural, and engineered formwork. These technologies basically determine the speed of
construction and labor intensity of concreting operations. There are various types of formwork
such as fixed insulated formwork and classic timber formwork.
Scaffolds include independent tied, roof saddle, stack and birdcage. Other prominent scaffold
constructions include hanging brackets, and the putlog and scaffold towers. Formwork and
scaffolding are essential components in civil engineering projects and are utilized by millions of
Scaffolding can be removed immediately; formwork can’t be removed
Scaffolding can be removed after the completion of the work while formwork should be removed
after 36 hours, 6 days or 28 days. It depends on the type of formwork.
Formwork must be strong enough to sustain the weight of the concrete it supports while it
hardens. Wet concrete exerts significant strain on the formwork, with far more pressure
generated at the bottom than at the top. If the formwork is not constructed to withstand the
requisite weights, it may twist or collapse when the concrete is filled.
Accidents can also occur when the formwork is lifted before the concrete has completely dried.
So, formwork is required to remain in place for a set number of days after wet concrete is put
into it. A moist blanket is usually placed on the exterior of the molds for a short period of time.
Formwork is often referred to as forms or shuttering.
Scaffolding and formwork have different functions
Scaffolding is required to hold the platform on which the construction workers will sit and work.
These are also required when a building has to be repaired or destroyed. The functions of
formwork and scaffolding are vastly different. The formwork acts as a form for the concrete,
providing shape, size, and durability to the freshly formed viscous concrete.
Scaffolding and formwork have different types
● Single scaffolding or brick layer’s scaffolding
It is a series of vertical members, firmly fixed into the ground in a row parallel to the building
wall. This form of scaffold is also known as putlog scaffolding and is used for bricklaying.
● Masons scaffolding or double scaffolding
This scaffolding is made up of two rows of scaffolding. It is utilized in situations when
inexpensive single scaffolding can’t be employed. It is sometimes referred to as an independent
● Cantilever scaffolding or needle scaffolding
Cantilever scaffolding is used when the ground is too weak to hold standards and work is to be
done in the upper section of the structure near the wall.
● Scaffolding that is suspended
This style of scaffolding is lightweight and is used for basic work such as pointing,
whitewashing, painting, distempering, and other similar tasks.
● Scaffolding with trestles
Trestle scaffolding is commonly used for repair and painting work. They are often deployed up
to 5 meters in height.
● Scaffolding made of steel
This scaffolding is comparable to timber scaffolding. Because rope-lashings and steel are
utilized instead of wood, this form of scaffolding may be employed at any height.
● Formwork for Walls
Wall formwork is far less complicated than other concrete elements. The forces acting on the
wall formwork are minimized. The majority of the load is carried vertically downwards. Ties hold
the panels in place on both sides. A form tie is a formwork accessory that is used to secure the
concrete wall forms against the lateral force of freshly put concrete. They retain ample space
between the shapes, resulting in walls of consistent thickness. The ties also serve as spacers.
● Formwork for Beams
Beam Formwork is a timber formwork that is built around a beam. This is a quite adaptable
wood beam formwork technique. It is adaptable to many slab geometries and is simple and
straightforward to construct. Formwork is a three-sided box that is held and supported in the
proper position and at the desired level. Beam formwork is made up of open-through sections,
and since it is not sealed at the top, it requires a stronger foundation to keep the sides in place.
The supports must be secured to the underside (the bottom horizontal section of a beam) and
give lateral support on both sides.
● Formwork for Columns
Column formwork often comprises wood or metal panels. Column formwork is built with panel
formwork parts or with individual formwork girders. They are typically modular in design,
allowing for fast construction and erection on-site while reducing manpower and crane time. The
idea is to build a closed box with frames similar to the precise size of the column and tighten it
down on the kicker left from the foundation or at the end of the column concreting process. Steel
column clamps or fastened yokes keep the box in place, and props hold it. Column formwork
sheeting, like beam formwork, is manufactured according to column measurements from
sheeting boards joined by cover straps. The sheeting panels are installed in a foot ring that is
bolted to the ground. The foot rim is made out of double-nailed planks. The foot rim should be
accurately measured because it determines the precise placement of the column. It serves the
same purpose as a base or beam formwork thrust-board.
Column clamps are fastened with wedges around the arch timbers, or a rim of boards is
constructed, similar to the foot rim. No further formwork tying, using tie cables or steel screws is
required. The clamp distances are set in the formwork project. They are typically 700 mm in
