Scaffolding is a temporary structure, usually constructed from metal tubes and timber or metal platforms. It is used to support builders, inspectors, cleaners, roofers and other professionals who need to carry out work at height.
The history of scaffolding stretches back thousands of years. Evidence suggests that early forms of scaffolding were used more than 17,000 years ago by the people who created the famous prehistoric cave paintings at Lascaux.
Basic scaffolding structures were also used by ancient civilisations around the world. In places such as ancient China and Egypt, workers built simple platforms from timber and secured the materials together using rope.
Modern scaffolding has developed far beyond these early structures. It is now available in a variety of designs and can be manufactured from several different materials to suit the requirements of each project.
This article explains how scaffolding is used today, its main advantages, the risks involved, its common applications and the alternative access methods that may be suitable for certain types of work.
What Is Scaffolding?
A scaffold, which may also be known as scaffolding or staging, is a temporary structure that provides people with a stable platform when they need to work at height or reach an area that is difficult to access.
These temporary structures are frequently used during the construction, maintenance, inspection or repair of houses, commercial buildings, bridges and other built structures.
Scaffolding provides support for workers, tools and approved materials while allowing work to be completed at different heights.
The Benefits of Scaffolding
Scaffolding has been used for thousands of years for one simple reason: it is effective. Even today, it remains one of the most useful and efficient ways for workers to access elevated areas.
The main benefits of using scaffolding for work at height include the following.
Access
Scaffolding can provide clear and stable access to almost any part of a structure.
It can be erected around walls, roofs, chimneys and other difficult areas, allowing workers to reach places that may not be safely accessible from a ladder.
Balance
A scaffold gives workers a firm platform beneath their feet.
This makes it easier for them to maintain their balance, change position and use tools while carrying out work at height.
Ease of Construction
Scaffolding can normally be assembled and dismantled relatively quickly by properly trained and competent scaffolders.
The amount of time required will depend on the height, size and complexity of the structure.
Long Lasting
Most professional scaffolding components can remain usable for many years when they are inspected, stored and maintained correctly.
This applies to systems made from steel, aluminium or timber, although every component must be checked for damage before being used.
Safety
Safety is one of the greatest advantages of scaffolding because it gives workers a stable and properly supported platform.
Guardrails, toe boards, safe access points, scaffold ties and other protective components can be included to reduce the risks associated with working at height.
However, working at height always involves some degree of risk. Where possible, companies may also consider whether inspections or preliminary assessments can be completed from the ground using other technology.
Serves as a Bridge
Some construction projects require workers to follow long or complicated routes to move between different working areas.
Connecting platforms and bridging sections within a scaffold can shorten these routes and allow workers to move more efficiently around the site.
The Dangers of Working on Scaffolding
Whenever a person works above ground level, there is a risk of falling or being injured. Working on a temporary structure such as scaffolding is no exception.
Scaffolding provides a stable platform, but it must be correctly designed, erected, inspected and maintained. It must also be used responsibly by everyone working on or around it.
The most common dangers associated with scaffolding include the following.
Defects
Scaffolding accidents can be caused by faulty or damaged components.
Examples include weakened steel tubes, cracked scaffold boards, damaged fittings or components that do not connect and lock together properly.
Every component should be inspected before installation, and damaged equipment should be removed from use.
Falling Objects
Tools, construction materials and debris can fall from scaffolding and injure workers or members of the public below.
To reduce this risk, scaffold platforms may require toe boards, brick guards, debris netting, protective fans or other suitable protective measures.
Workers should also keep platforms organised and avoid leaving loose materials near an open edge.
Weather
Changing weather conditions can make working at height particularly dangerous.
Rain, ice or snow may make scaffold boards slippery. Strong winds can affect loose materials, protective sheeting and certain scaffold structures.
Scaffolding should be checked following severe weather, and workers should not use it when conditions are considered unsafe.
Ignoring Safety Standards
A number of serious scaffolding accidents happen because basic safety requirements are ignored.
Examples include overloading a working platform, removing scaffold ties, failing to install guardrails or positioning the structure too close to dangerous electrical sources.
The scaffold should only be used for the work and loads it was originally designed to support.
Inadequate Training
Both scaffold construction and scaffold use require suitable training.
The scaffolders responsible for erecting and dismantling the structure must understand the correct construction methods and safety requirements for the particular system being used.
Workers using the scaffold should also understand how to access it properly, recognise possible hazards and report any damage or movement.
Inadequate or Weak Planking
Every scaffold used for professional work must have strong and properly supported working platforms.
Weak, damaged or incorrectly positioned boards can create serious fall and trip risks.
Posts, supports, towers and other access mechanisms must also be suitable for the work and maintained in safe condition.
Inexperience, Incompetence and Negligence
Working with people who lack experience, suitable training or respect for safety procedures can be extremely dangerous.
Careless actions by one person can put everyone on or below the scaffold at risk.
Workers should never alter the scaffold, remove safety components or attempt to repair it without the permission of the responsible scaffolding contractor.
Insufficient Safety Equipment
Workers must still have access to appropriate safety equipment even when the scaffold has been correctly designed and installed.
Depending on the project, this may include helmets, protective footwear, harnesses, high visibility clothing and other personal protective equipment.
The required equipment should be determined by the risks associated with the work.
Poor Construction
Scaffolding accidents are sometimes caused by incorrect construction.
Examples include failing to secure connection points, leaving out essential bracing, using unsuitable foundations or failing to install guardrails and toe boards.
The completed scaffold should be inspected before it is made available for use.
Poor Maintenance
Scaffolding must be properly maintained if it is to remain safe and structurally reliable.
Metal components can corrode, fittings may become damaged and scaffold boards can crack or weaken over time.
Platforms can also become slippery or obstructed if the structure is not regularly cleaned and checked.
Uses of Scaffolding
Scaffolding is used for many different activities. Some of its most common applications are explained below.
Cleaning
Workers regularly use scaffolding to clean windows, cladding and other exterior parts of tall or difficult to access buildings.
The scaffold provides a larger and more stable platform than an ordinary ladder, allowing workers to carry cleaning tools and move along the building.
Construction
Scaffolding plays an important role in construction because it allows builders to stand and work on a stable platform above ground level.
This is particularly important for tall buildings and large structures, but scaffolding is also widely used for lower level work on homes, extensions, roofs and commercial properties.
Industrial Inspections
Inspection work is another common reason for installing scaffolding.
A scaffold allows inspectors to reach areas that cannot be viewed or examined properly from the ground. They can then carry out visual inspections, measurements and different forms of testing.
Internal scaffolding and other temporary access structures may also be used when inspecting large industrial buildings, tanks, boilers or enclosed spaces.
Regardless of the type of inspection, the basic purpose remains the same. Scaffolding allows the inspector to reach the required height and perform the necessary checks from a stable platform.
Maintenance
An inspection is often the first stage of a maintenance project because it helps identify damaged or defective areas.
Once those areas have been located, maintenance workers may use the same scaffold to complete the necessary repairs.
Scaffolding is commonly used for roof repairs, brickwork, painting, rendering, gutter replacement, chimney work, window installation and general property maintenance.
Other Uses
Different scaffolding systems can also be used for:
Art installations
Concert stages
Exhibition stands
Grandstand seating
Observation towers
Temporary shoring
Ski ramps
Public events
Temporary platforms
Specialist access projects
Alternatives to Scaffolding: Using Inspection Drones
Scaffolding has several disadvantages as well as advantages. Working at height carries risk, tools or equipment may fall, and large structures can take time to erect and dismantle.
Depending on the project, alternative access methods may be available.
For certain maintenance jobs, rope access may be more targeted and adaptable than installing a complete scaffold.
For building and industrial inspections, drones are also becoming a practical alternative for collecting visual information from difficult areas.
A drone can fly close to roofs, chimneys, walls and elevated structures to capture photographs and video. This allows inspectors to review certain areas without immediately placing themselves at risk by climbing a scaffold or using ropes.
Some specialist inspection drones can also carry different sensors depending on the requirements of the project.
The main reasons inspectors may use drones instead of internal or external scaffolding include the following.
Safety
Drones can collect visual information remotely.
This allows an inspector to remain on the ground rather than working at height to obtain the same preliminary images or video.
Savings
Installing and dismantling scaffolding solely for an inspection can be expensive, especially on large buildings or industrial structures.
Using a drone for an initial visual survey may reduce the amount of scaffolding needed and help the customer understand which areas require closer examination or repair.
Reduced Downtime
Large scaffolding structures can take time to erect and remove.
On commercial or industrial sites, this can extend the period during which an area or asset cannot be used normally.
A drone inspection may collect the required visual information with less disruption.
Speed
Drones can capture images and video from a large area relatively quickly.
This may allow inspectors, surveyors or contractors to review a building faster than they could through a complete manual inspection from scaffolding.
However, drones cannot complete physical construction, maintenance or repair work.
When workers need to repair a roof, replace brickwork, paint a building, install windows or carry materials, a properly designed scaffold may still be the safest and most practical access solution.
