Scaffolding - when scaffolding pays off and when an aerial work platform is the better choice

Scaffolding accompanies every larger construction project - from facade renovation and new builds to industrial installation. Yet stationary facade scaffolding is far from the only option for safe work at height. Over the last two decades, mobile elevating work platforms, telescopic boom lifts and scissor lifts have become a real alternative: ready for use faster, more economical for short jobs and safer for spot work over obstacles.

This guide explains the system of modern scaffolding, shows which jobs still belong to classic scaffolding - and where an aerial work platform is technically and economically superior. Luibl Rental & Sales is a specialist in access equipment and delivers aerial work platforms by low-loader from Passau throughout the Czech Republic that replace or usefully complement scaffolding in many jobs.

Scaffolding refers to the professional erection of temporary working and protective structures that give people safe access to workplaces at height. A scaffold is a stationary, modular structure made of frames, decks, guardrails, diagonals and anchors. It is planned for the specific project, erected, accepted by a competent person and dismantled on completion.

According to the usual system of standards, scaffolding comprises three main functional categories:

• Working scaffolds serve as a platform for construction, installation and maintenance activities
• Protective scaffolds protect people and structures against falls or falling objects
• Falsework carries loads from formwork or structures during construction

Distinct from classic scaffolding is the use of mobile elevating work platforms. Mobile elevating work platforms are motor-driven mobile machines that lift people and material to the workplace and hold them there. Legally they are not considered scaffolding but work equipment within the meaning of Government Regulation No. 378/2001 Coll. This has far-reaching consequences for planning, staff qualification and operating costs - we return to this in section 7.

Facade scaffolding (frame scaffolding)

Facade scaffolding is the standard system in Central European construction. It consists of prefabricated frames that are anchored to the facade and connected with decks. Typical manufacturers are Layher, Plettac, Huennebeck, Rux and Altrex. Areas of use: plastering and painting, thermal insulation (ETICS), roofing, facade renovation. Erection and dismantling require trained scaffolding staff.

Modular scaffolding (system scaffolding)

Modular scaffolds such as Layher Allround or Plettac Perfect consist of vertical standards with connection nodes at regular intervals. Ledgers and diagonals are connected at any angle. This makes it possible to build complex geometries - church towers, stairwells, industrial plants, bridges.

Mobile scaffold tower (mobile access tower)

Mobile scaffold towers to CSN EN 1004-1 are single-bay mobile aluminium structures with castors. They are used indoors up to a maximum platform height of 12 m and outdoors up to a maximum of 8 m. They are erected by competent, instructed persons - no scaffolder qualification required. Use: interior finishing, small ceiling renovations, painting.

Roof edge protection scaffold

A roof edge protection scaffold is a protective scaffold for fall protection when working on pitched roofs. The top deck is no more than 1.50 m below the eaves, and the catch level catches falling persons. When its use is required is set by Government Regulation No. 362/2005 Coll. (work at height).

Birdcage scaffolding and falsework

Birdcage scaffolds are erected across the full area of an interior - typically for ceiling renovations in halls, churches or railway stations. Falsework to CSN EN 12812 carries temporary loads, for example concrete formwork in bridge construction.

Suspended and cantilever scaffolding

Suspended scaffolds are lowered from above, for example under bridges. Cantilever scaffolds project from one side of the structure where erection from the ground is not possible - for example over water or traffic routes.

Chassis without scaffold function: mobile elevating work platforms as an alternative

Alongside these classic types of scaffolding, the mobile elevating work platform has established itself as a fully fledged alternative for all work where the workplace is at specific points or changes. Four main types cover almost all jobs:

• Scissor lifts - vertical lift, platforms up to 34 m working height, load capacity up to 1,000 kg
• Telescopic and articulating boom lifts - outreach and work over obstacles, up to 58 m working height
• Spider lifts - rough-terrain capable with gradeability over 50%
• Truck-mounted platforms - fast change of location, no set-up time at the site

For many projects where scaffolding used to be ordered by reflex, an aerial work platform is today the more economical, faster and often also safer solution.

The following table compares the most important key figures. The reference values are typical figures for facade scaffolding and mid-range mobile elevating work platforms.

Criterion	Facade scaffolding	Mobile scaffold tower	Mobile elevating work platform
Typical working height	up to 24 m (higher with stability verification)	indoors 12 m / outdoors 8 m	scissors up to 34 m, articulating booms up to 58 m
Outreach	0 (tied to facade)	0	up to 41 m (articulating boom)
Set-up time on site	1-5 days depending on area	30-90 minutes	5-15 minutes (positioning, outriggers)
Required qualification	scaffolder, competent person	competent person	required operator qualification (IPAF)
Working position	fixed platform	fixed platform, movable	freely positionable in 3D
Acceptance	mandatory after erection	mandatory after erection	periodic inspection under Government Regulation No. 378/2001 Coll.
Economical from	job duration > 3 weeks	job duration > 1 week	job duration hours to several weeks

Key message: The shorter the job, the greater the outreach and the more demanding the terrain, the more clearly the calculation shifts in favour of the aerial work platform.

Clear scaffolding jobs

Scaffolding is indispensable when work is carried out over a large facade area for a longer period. Specifically:

• Facade renovation over several weeks or months
• Installing an external thermal insulation composite system (ETICS)
• Roofing and sheet metal work at the eaves
• Plastering and stucco work with a lot of material stored on the working level

Here the scaffold provides a continuous working platform on which material can be stored, cut and processed. An aerial work platform would be economically inferior for these jobs because the length of time on site would drive costs up sharply.

Clear aerial work platform jobs

For the following work, the mobile elevating work platform is technically and economically superior to scaffolding:

• Spot maintenance work - individual lights, cameras, air conditioning units, gutters
• Industrial installation - hall lighting, fire protection systems, ventilation, sprinkler systems
• Tree care and green space work - reaching over tree crowns is hardly possible with scaffolding
• Facade cleaning - glass surfaces, solar systems, billboards
• Work over obstacles - over roofs, plants, water, traffic routes
• Installation in logistics centres - work above racking that is inaccessible to scaffolding
• Short jobs under 2 weeks - where erecting and dismantling scaffolding takes longer than the actual work

The Manitou 160 ATJ (articulating boom lift with 16 m working height) or Magni RTH 6.39 (roto telehandler with basket up to 39 m) handle work that would be either disproportionately expensive or simply impossible with scaffolding.

Hybrid jobs

Many projects benefit from a combination. Example of a car plant: for ongoing maintenance of production equipment, the hall is not scaffolded - instead, high-rack scissor lifts with heights of 22 m, 28 m and 33 m are used. On the facade, however, scaffolding remains the basis, supported by a truck-mounted platform for hard-to-reach areas.

The choice between scaffolding and an aerial work platform follows a robust decision logic. In practice, six questions settle over 90% of all cases:

1. How long does the job last? Under 2 weeks: aerial work platform. Over 4 weeks with area work: scaffolding. In between: calculate.

2. How many metres of outreach are needed? Zero outreach and work directly on the facade: scaffolding. Any other constellation: consider an aerial work platform.

3. How many people work at height at the same time? More than two people with material: scaffolding. One to two people with tools: aerial work platform is sufficient.

4. What material needs to be stored on the working level? Nothing to light tools: aerial work platform. Pallets, insulation boards, mortar: scaffolding.

5. What is the ground like? Paved and level: all options. Rough or steep: spider lift (gradeability over 50%).

6. Do obstacles need to be bridged? Yes (roofs, extensions, plants): articulating boom lift. No: scaffolding or scissor lift.

A simple rule of thumb for the construction trades: anyone considering switching from scaffolding to an aerial work platform for the first time typically starts with short maintenance jobs. The hourly cost of an aerial work platform is higher than the daily scaffolding contribution - but set-up time is eliminated and work starts within an hour of delivery.

Scaffolding and the use of aerial work platforms are governed in the Czech Republic and Austria by different but overlapping regulations.

Czech Republic

The key regulations are Government Regulation No. 378/2001 Coll. (safe operation of work equipment), Government Regulation No. 362/2005 Coll. (work at height) and occupational safety rules (Act No. 309/2006 Coll.). For scaffolding, CSN EN 12810 and 12811 (facade scaffolding) and the applicable safety rules on hazards when using scaffolding also apply.

People who erect scaffolding need appropriate professional qualifications. Once erected, the scaffold must be inspected by a competent person before use and released in writing. For mobile elevating work platforms, the required operator qualification in line with applicable Czech safety rules and CSN EN standards applies - regular refresher instruction, a documented operator authorisation (often to the IPAF standard) and periodic inspection of the machine under Government Regulation No. 378/2001 Coll. are recommended.

Austria

In Austria, the Work Equipment Ordinance (AM-VO) and the requirements of AUVA (Allgemeine Unfallversicherungsanstalt) apply. For mobile elevating work platforms, annual inspection by a competent person is prescribed. Operator training follows AUVA leaflet M 385.

Inspection duties at a glance

• Scaffolding: acceptance after erection, check before each working day, new inspection after any significant change
• Mobile scaffold tower: erection by an instructed person, release by a competent person
• Mobile elevating work platform: periodic inspection under Government Regulation No. 378/2001 Coll., instruction on the specific machine

Anyone renting aerial work platforms from Luibl receives machines with a valid inspection report under Government Regulation No. 378/2001 Coll. Long-term rentals usually include the periodic inspection at no extra charge.

The classic rent-or-buy decision looks somewhat different for scaffolding than for aerial work platforms.

Rent or buy scaffolding

For private individuals and trade businesses with occasional scaffolding needs, renting through a scaffolding contractor is the norm - including erection, dismantling and structural assessment. Buying a mobile scaffold tower pays off for recurring in-house use, for example at painting companies.

Renting or buying an aerial work platform

Here the calculation shifts significantly. New aerial work platforms quickly cost 40,000 euros (scissor lift) to over 350,000 euros (roto telehandler). Experience shows that payback starts at 150-200 operating days per year. For most companies, renting is the economically superior option - especially with long-term rental terms from 3 months.

The hybrid strategy

Many companies do best with a clear split: buying a single, frequently used scissor lift for core work and renting specialist equipment (articulating boom lifts, roto telehandlers, high-rack scissor lifts) on a project basis. Here Luibl Rental acts as a partner for specialist equipment both for end customers and for other rental companies.

When you need neither your own scaffold nor your own platform

For individual projects with a clearly defined duration, a pure rental solution is the obvious choice. Luibl delivers by low-loader from Passau throughout the Czech Republic. Periodic inspection under Government Regulation No. 378/2001 Coll., operator briefing and, if required, a fitter are included in the package.

Scaffolding is no longer a monolithic topic. Anyone planning work at height today should consider two parallel worlds: the classic scaffold for extensive, longer facade work and the aerial work platform for selective, mobile, fast jobs. Technically the distinction is clear, economically it is often surprising: in many cases the aerial work platform clearly beats the scaffold - even on projects where people reflexively reached for scaffolding.

Luibl Rental & Sales delivers aerial work platforms of all classes by low-loader from Passau throughout the Czech Republic - from compact electric scissor lifts for indoor use and spider lifts for rough terrain to roto telehandlers with a 39 m basket height. A single contact person looks after platforms, telehandlers and forklifts alike - and takes care of delivery, periodic inspection under Government Regulation No. 378/2001 Coll., operator briefing and, if required, a fitter.
