Single Scaffolding
Single scaffolding, commonly referred to as bricklayer’s scaffolding, is one of the oldest and most traditional types of scaffolding used primarily in brick masonry construction. This system is simple to construct and has been used for centuries to provide work platforms for masons and other tradespeople. While technology in scaffolding has evolved, single scaffolding remains popular due to its cost-effectiveness and straightforward assembly.
Structure and Components
Single scaffolding consists of a single framework of vertical poles (standards), horizontal poles (ledgers), and shorter tubes (putlogs) that extend out from the building. The standards are firmly planted in the ground at regular intervals, typically about 2 to 2.5 meters apart. Ledgers connect the standards horizontally at every 1.2 to 1.5 meters. Putlogs are then placed at right angles to the wall, one end resting in the wall (in holes left in the masonry) and the other on the ledgers. For added stability, diagonal braces (cross bracing) may also be used.
Assembly and Application
The simplicity of single scaffolding makes it particularly suitable for construction work up to a height of about 15 meters. As it relies on the support from the building, it is predominantly used where the ground near the building is uneven or restricted. This method is favored in bricklaying because the scaffolding provides a seamless workflow, allowing masons easy access to work at different heights as the building ascends.
Safety and Limitations
While single scaffolding provides a cost-effective and straightforward solution for masonry, it has its limitations, particularly in terms of load-bearing capacity and stability compared to more modern scaffolding systems. The structure’s reliance on the building for support also limits its use to certain types of construction. It is not suitable for use in stone masonry, for example, where the putlogs would need to be supported differently since stone walls are not punctured for embedding putlogs.
Ensuring the safety of single scaffolding involves meticulous planning and careful construction. Standards must be securely planted into the ground, and all components should be checked for stability and wear. Regular inspections are crucial, particularly after adverse weather conditions, to ensure the integrity of the scaffolding.
Regulatory Compliance
In the UK, the use of single scaffolding must comply with the Work at Height Regulations 2005. These regulations mandate that scaffolding must be erected, altered, and dismantled by competent persons under the guidance of a qualified supervisor. Furthermore, the construction must include safety features such as guardrails and toe boards to protect workers from falls and falling objects.
Advantages
The primary advantage of single scaffolding is its simplicity and ease of construction, making it ideal for smaller, less complex projects. It requires fewer materials than more complex scaffolding systems, which can lead to lower costs and quicker setup times. Additionally, because it uses fewer components, single scaffolding can be easier to inspect and maintain than more elaborate setups.
Modern Use and Considerations
Despite its traditional roots, single scaffolding is still widely used in construction projects around the world. However, contractors must consider the specific requirements and limitations of their projects when choosing this type of scaffolding. For projects involving tall structures or requiring high load capacities, more robust systems like system scaffolding may be more appropriate.
Conclusion
Single scaffolding remains a staple in the construction industry, particularly for brick masonry work. Its simplicity, cost-effectiveness, and ease of assembly make it a viable choice for many low-rise projects. However, as with any construction equipment, ensuring safety through regular inspections and adherence to regulations is paramount. As construction technologies advance, single scaffolding continues to hold its place, especially in scenarios where traditional methods are preferred or logistical constraints exist.
Funding
If you are a scaffolding company and are looking to grow, you will probably need finance at some point to cover the cost of equipment and vehicles. First Oak Capital is ideally placed to help you and more information can be found on our scaffolding finance page here.
