Although setting up scaffolding can be time-consuming, following these scaffold set up instructions will ensure proper construction.

scaffold setupSteps to Set Up a Scaffold

To properly set up scaffolding at your worksite or facility, follow these steps: 

1. Prepare and Organize All of Your Parts

Before you start assembling the scaffolding sections, it is important to organize all of your parts and tools in one place. You’ll need the scaffold unit, pigtails, toggle pins, scaffold planks, and a level. 

2. Assemble the Frame and Baseplates

Start setting up a scaffold by laying the two end frames approximately 7 feet (or at the width of your cross braces) apart near your work area. Then install the baseplates to save hassle later on in the process. While scaffold models can vary in assembly, most feature an open tube that will slide over the base of the adjustable screw bar, which is then secured using pigtails, toggle pins, or other locking accessories. 

3. Assemble the Cross Brace

Next, assemble the cross brace by raising one end frame and sliding the crossbar ends over the pins on the frame. Lock the pins and lay the cross brace on the ground to temporarily support the first end frame while you raise the second one. Once the second end frame is raised, place the other end of the cross brace over the pins and lock them into place. To finish this setup, repeat the same process on the opposite side.

4. Secure and Level the Scaffold

Place the scaffold at the desired location. Since a safe scaffolding installation begins with a solid foundation, add 2×10 blocks under each baseplate for sturdier support when using scaffolding on soft ground. Use the adjusting screws on the unit to level the scaffold. 

5. Install the Wooden Planks

Lifting the scaffold plank from the middle, angle it through the end frames until both ends of the plank are above the frame. Level the plank and lower it until the hooks are attached to the bars of both end frames. Next, secure the plank with swivel locks. Repeat this step until you’ve installed all the wooden scaffold planks. 

6. Install Guardrails

Add the guardrails by securing them to the corner posts of each frame using a pigtail, toggle pin, or other locking mechanism. Install top and bottom guard rails between the posts. 

7. Prepare and Set Up a Workstation

Bring all your work items to the scaffold platforms. Setting up a workstation on the scaffolding platforms will help you complete your project quicker and more efficiently. 

8. Ensure Safe Position of Scaffolding

If setting up scaffolding around electrical power lines, watch closely when moving the scaffold around your worksite. Keep scaffolding at a safe distance from danger to keep you and your workers safe on the job.

Masonry Scaffolding

Leave a Comment

By their nature, work sites are fluid and ever-changing. In order to complete the main structure, smaller, temporary structures like scaffolding are often necessary. Scaffolds are commonly used because they are relatively inexpensive, easy to set up, and easy to remove. They offer a quick and adaptable way to meet jobsite’s challenges. 

Bricklayer and masonry scaffolding are essential facets of many construction sites. The scaffolding’s role is to provide a safe and sturdy platform that allows multiple masons and construction professionals to work on a project simultaneously at elevated heights. 

What is Masonry Scaffolding?

There are two main types of scaffolding one might encounter on a construction site: supported scaffolds and suspended scaffolds. The most common subtype of supported scaffolding is known as masonry scaffolding or bricklayer scaffolding. 

On their most basic level, masonry scaffolding consists of a metal frame with planks inserted. Those planks serve as both a work surface and a ledge on which to stand. The key elements of the scaffolding’s design include:

  • Standards (vertical portion of frame)
  • Ledgers (horizontal portion of frame)
  • Braces (diagonal cross-beams attached to standards)
  • Putlogs (beams that stabilize the frame against the wall)
  • Boarding/planks (work surface)

While scaffolding allows laborers to work with an augmented reach, there are numerous safety standards in place to ensure that platforms are stable during operation. For starters, careful inspection of the scaffolding must be performed at the outset of each shift, as stipulated by OSHA. 

The overall scaffold must not exceed a 4:1 ratio between the height and the base. Each of the planks must have 1-inch clearance between them, and they must overhang the edge of the standard by 6 inches — unless the plank exceeds 10 feet, in which case it must overhang by 18 inches. In terms of load capacity, each plank must be able to support up to 4 times the weight of the people, equipment, and materials upon it.

Guardrails are an incredibly important aspect of scaffolding safety. The regulations may vary slightly based on state guidelines but are largely based on OSHA requirements. In general, guardrails must be in place if the scaffold is 10 feet tall and the rails must be present on all open sides. In certain locations that are superficially above water, the minimum height can be as low as 5 feet. Additionally, each plank must have a 4-foot high toe-board installed on the outer edge to prevent materials from falling on laborers or other passersby below. 

The Advantages and Disadvantages of Scaffolds

As with any worksite solution, there are both pros and cons involved with the use of scaffolding. Some of the benefits include:

  • Masonry scaffolding provides a safe and convenient surface for masons, bricklayers, and other workers to operate.
  • Scaffolding provides better support and safer access to out-of-reach areas than ladders. 
  • Scaffolds allow precision work at elevated heights up a building’s facade. 

The cons associated with scaffolding are more complex and have to do with proper setup:

  • If scaffolding isn’t built using the right material for the jobsite conditions, it can have disastrous effects. 
  • A poorly assembled scaffold is likely to collapse or become easily overloaded. 

Kennison Forest recommends our solid-sawn scaffold planks. They are designed to exceed OSHA standards and endure under even the toughest of loads.

Do’s and Don’ts of Scaffold Design

Leave a Comment

Scaffolds are a critical element in many construction sites. The temporary structures provide support and stability to access and working platforms so workers can use them safely. However, working at elevated heights poses a higher risk of injury to life and limb for employees, including in regard to falls and falling objects. As such, it is important to design, install, and use scaffold carefully to avoid unsafe working conditions and practices. The Work Health and Safety (WHS) Act imposes regulations dictating proper design, erection, alteration, and dismantling of scaffolds aimed toward worker safety.

In the following guide, we discuss some of the do’s and don’ts of scaffold design, construction, and use.

Designing the Scaffold

Scaffold safety begins at the design phase. While proper construction with quality materials is also important, it cannot stop an improperly designed scaffold from endangering employees. As such, the scaffold designer should carefully consider the following factors before putting pen to paper:

  •   Intended use
  •   Potential worksite risks and hazards
  •   Ground and foundation conditions
  •   Load bearing capacity, including dead loads and live loads
  •   Anchoring, bracing, and tying requirements
  •   Supporting structures
  •   Edge protection elements

Below we outline some of the considerations to keep in mind when designing a scaffold.

Do: Identify Potential Hazards Early

Before designing a scaffold, it is essential to assess the worksite in its entirety, paying special attention to conditions that could lead to unsafe working environments. Some of the other factors to consider include the evenness and stability of the ground and the structural areas subjected to the greatest loads and stresses.

Do: Consider the Type of Work Performed

The type of work performed at the worksite should also be considered as it influences the design and construction of the scaffold. Additionally, it affects the expected dead and live loads to which the scaffold will be subjected.

Do: Maintain Proper Documentation

For highly specific or unique scaffold designs, the designer must prepare and provide a safety report outlining the potential for distinct hazards and risks and how to eliminate or control them. The documentation may also include instructions on how to erect and use the scaffold correctly for minimal safety risks.

Don’t: Take Material Selection Lightly

A critical early consideration is material selection, which determines the strength, stability, and load-bearing capacity of the final installation. The walkboards employed in the construction of scaffolds are made from either wood or metal, both of which offer unique advantages and disadvantages. For example, metal planks—such as those made from aluminum—are prone to warping over time. Wood planks are made from a variety of woods, all of which differ from construction-grade lumber.

Many construction industry professionals in North America prefer to use Douglas Fir wood for scaffolds planks, which is the material used in Kennison Forest Product products. The wooden boards comply with all OSHA and ANSI standards, meet ICBO 1997 Uniform Building Code Structural LVL requirements, and pass individual proof loading and testing conditions.

Once a scaffold design is finalized, the contractor(s) should work together with designer(s) to ensure the structure is erected as planned. Below we outline some of the considerations to keep in mind when constructing a scaffold.

Do: Acquire the Required Documentation

There are several forms of documentation that may be required when constructing a scaffold. For example:

  •       A safety report, as indicated above, is necessary for any scaffold design with unique or unusual elements.
  •       A Safe Work Method Statement (SWMS) is needed if there is a risk of a worker falling more than two meters.
  •       A high-risk work license is mandatory if there is a risk of a worker falling more than four meters.

High-risk construction work may also encompass other work conditions, such as:

  •       If temporary supports are needed to prevent collapse during structural alteration or repair operations
  •       If the structure is on or near energized electrical systems or services
  •       If the structure is located near a moving powered mobile plant

If the construction of a scaffold involves any of the above, the SWMS prepared must identify the type of work performed, indicate the health and safety risks and hazards, and describe control measures and how they will be implemented, monitored, and reviewed.

All of the above documents should be developed and/or shared with the workers and their representatives carrying out the construction work.

Do: Follow a Construction Plan

For construction work that does not require an SWMS, a scaffold plan can guide workers in constructing, using, maintaining, repairing, and dismantling the structure safely. The plan should be developed with regard to all parties relevant to the work and workplace, including the designer, the contractor or builder, the workers, and other industry consultants with extensive scaffold knowledge. It should address exactly how and where the structure should be erected, including the design basis, type, foundation conditions, entry and exit points, and more.  

Don’t: Forget the Plant Design Registration Number

As per Part 1 of Schedule 4 in the WHS regulations, prefabricated scaffolds and scaffolding must have their designs registered. When using these structures, the site owner or manager should keep the design registration number readily available. Rental companies providing temporary scaffolds and scaffolding should present the number on the contract or supply docket.

Using the Scaffold

Before using a scaffold, workers must be trained in how to use it properly. The Occupational Safety and Health Administration imposes several regulations regarding design (1926.454), construction, training (1926.454), and use. Training programs should identify the hazards associated with different types of scaffolds and the appropriate measures for controlling and minimizing them. Additionally, they should address the following topics:

  •   Erection
  •   Disassembling
  •   Moving
  •   Operating
  •   Repairing
  •   Inspecting
  •   Maintaining
  •   Planning
  •   Using personal protective equipment (PPE)
  •   Accessing
  •   Installing guys, ties, and braces

Additional training is necessary if there are any changes to the structure or worksite that may add or change potential hazards. An employee may also receive further training if the employer identifies a lack of necessary skill, understanding, or proficiency in following safe work practices.

Below we outline some of the general considerations to keep in mind when using a scaffold.

  •       Do inspect the scaffold before the start of the work shift
  •       Do wear appropriate PPE
  •       Do keep both feet on the scaffold’s decking
  •       Do chock and lock wheels before climbing a scaffold
  •       Do level the scaffold when it is moved
  •       Do use safety belts and lanyards when working at or above 10 feet from the ground
  •       Do employ safety netting to catch falling materials and equipment
  •       Do utilize the ladder when climbing the scaffold
  •       Do prepare and maintain an emergency plan
  •       Don’t go on the scaffolding during loading and unloading operations
  •       Don’t overload the scaffold
  •       Don’t leave anything on the scaffold when a shift ends
  •       Don’t use a scaffold that is missing a guard rail or plank or attempt to replace structural components with blocks or boxes
  •       Don’t stand on ties, guardrails, extensions
  •       Don’t use a scaffold during inclement weather or after inclement weather if the scaffold is still slick
  •       Don’t lean off the edge of a scaffold, overreach guardrails, or attempt to jump between scaffolding
  •       Don’t move or rock a scaffold when someone is standing on it

Common Scaffolding Applications

Leave a Comment

Scaffolds are temporary platforms that allow easy access to an industrial work site or construction site. Depending on the application, scaffolds can also be used to provide architectural support to a building even as work continues on the structure. Typically constructed from cost-effective, sturdy timber and sometimes supplemented by aluminum or steel supports, scaffolds are affordable and easy-to-erect, offering flexible and low-cost access to structures. 

Although scaffolds are often associated with the construction industry, they find extensive use across industrial facilities such as petrochemical sites and refineries. In these settings, scaffolds often allow significant cost-savings when constructing access platforms, using cost-effective materials and flexible supports to yield stable and affordable structures.

Different types of scaffolds support a wide range of applications. For example, although scaffolds are almost always temporary structures, some scaffolds are fixed more permanently in place than others. In some cases, such as repairs to a fixed-height tank, the worker does not need to adjust the height of the platform once it is in place. Traditional timber scaffolds or trestle scaffolds, both of which combine plank walkways with stationary supports, are appropriate in this situation. 

In other situations, such as allowing a window washer access to higher floors of a building, greater flexibility is necessary. In these cases, clients might opt for suspended scaffolds, which combine scaffolding planks with cables and ratchets so that the surfaces can easily be raised and lowered.

Regardless of the specific design or industrial application, virtually all scaffolds use planks to form the platforms. Planks offer the ideal combination of strength and dimensional stability while still being affordable and readily available. Kennison Forest is the leading name in scaffold planks, offering OSHA and ANSI-compliant boards for use in construction, petrochemical, refinery, and industrial industries.

Scaffolds in the Petrochemical Industry

The petrochemical industry remains central to the global economy, transforming fossil fuels into the chemical constituents of plastics, detergents, synthetic fibers, and other essentials. Petrochemical facilities primarily consist of chemical processing plants and refineries, which produce olefins, aromatics, and synthesis gases in bulk quantities.

To enable such large-scale chemical production, petrochemical facilities employ massive tanks, tall chimneys, and vast warehouses, so access can be a significant challenge when performing maintenance on sensitive equipment. Petrochemical scaffolds can be constructed quickly and easily for maintenance, safely allowing access to otherwise unreachable points in petrochemical facilities. These facilities rely on scaffolds as an efficient and cost-effective means of enabling access to boilers, vats, pressure vessels, steam generators, chimneys, and similar pieces of elevated equipment.

Scaffolds in the Refinery Industry

The refinery industry is a specific subset of the petrochemical industry that transforms crude oil into new, usable chemical products. Unprocessed oil has very few practical applications, but its distilled and purified components can be used in a great number of products. Because of this, oil refining is a multi-trillion dollar industry on its own, and refineries create the gasoline, kerosene, and diesel fuel that power a massive portion of the economy.

Like other petrochemical facilities, refineries employ many large pieces of equipment that can only be accessed with scaffolds. Fixtures like heating exchangers, cooling towers, pressure vessels, and piping all tend to be elevated to an extent that they cannot be easily accessed without support structures. Thus, since most routine maintenance in a refinery occurs some distance above the ground, scaffolds play an integral role in keeping sensitive equipment running and keeping maintenance employees safe.

Scaffolds for Construction & Other Industries

Of all industries that use scaffolds, the platforms are most closely associated with the construction industry. Scaffolds are used at almost every stage of construction to provide structural support while providing safe, convenient passage for laborers. Construction scaffolds are also designed to safely bear static and dynamic loads, meaning that workers can safely carry and store heavy equipment even at a height. When sized appropriately, this benefit also minimizes the number of trips that workers must take around a worksite, which can dramatically increase efficiency while also protecting against strain. 

Other Industries

Although petrochemical, industrial, and construction facilities rely heavily on scaffolds, other industries also use these structures for convenient and affordable access to structures. These include:

  • Renovation 
  • Building Inspections
  • Civil Engineering
  • Window Cleaning
  • Film, Television, and Theater
  • Marine Construction

In general, any industry that involves constructing or maintaining large structures can benefit from secure scaffolds. In these settings, as in the construction and petrochemical industries, scaffolds help workers clean, repair, inspect, and build structures in the most cost-effective manner possible, all without sacrificing safety.
