Suspended Scaffolds: The Do’s And Dont’s

The hoisting of a suspended scaffolding and the working of scaffolders from it usually appears as an extremely daring sight from the ground. Every operation undertaken on suspended scaffoldings, be it of window washing or building exterior repair, is accompanied by extensive checking of the entire suspension system. The safety and security of the workers lie in the able supervision of a competent person.  Here are a few important points when considering working on a suspended scaffold.

• Supporting outrigger beams must be able to support at least 4 times the intended load. To keep a scaffold from falling to the ground, it must be attached to the roof, tied to a secure anchorage, or secured with counterweights. The suspension ropes and rigging must support at least 6 times the
intended load.
• Counterweights must be attached to secure and strong places on a building so they won’t move.
Do not use bags of sand or gravel, masonry blocks, or roofing materials that can flow or move.
• Do not use gas-powered equipment or hoists. Hoists must have automatic brakes for emergencies.
• A 1-point or 2-point suspended scaffold must be tied or secured to prevent swaying.

Some Interesting Facts about Scaffolding

Points of Interest

From a distance, scaffolding looks like a maze of criss-crossing steel pipes that encircles a building. But peer closely and you will realize that complex and precision engineering is at work behind the lattice.

Here are some interesting facts about scaffolding:

  • It is believed that scaffolding originated in ancient North Africa and China. A Greek wine cup, also known as a kylix and dating back to the fifth century, contains an image of a statue of a warrior within a scaffolding.
  • Scaffolding today is mainly made of metal pipes. But in some parts of Asia, scaffolding is made of bamboo and is even used when building very tall skyscrapers.
  • Until the 20th century, scaffolding was made mainly of wood. However, shortages in the supply of wood in various regions prompted manufacturers to look for other sources.
  • W.A. de Vigier is credited with designing an adjustable steel prop that revolutionized scaffolding designs all over the world. This steel prop forms the basis of trench sheeting and falsework, support slab formwork, and wall formwork.
  • The most famous scaffold designer in history is probably Michelangelo, the great painter, sculptor, and architect.  The scaffold that he had designed to paint the ceiling of the Sistine Chapel is a conversation piece in itself.

Extreme Scaffolding

This is extreme scaffolding, but to most scaffolders it is just another day at the office.  The surging waves and the strong gusts of winds are just occupational hazards that they have to contend with as part of their work.

The life of a worker at Scaffold Resources is no different.  Well, maybe we don’t have to deal with giant waves, but we have undergone the rigorous training program at Scaffold so we would be prepared for anything.

Suspended Scaffolding : A Basic Requirement For Window Washing

The foremost use of suspended scaffolding is in window washing services that only professional scaffold workers can attempt. The high rise buildings and their elaborate glass panes need to be cleaned at regular intervals of time because they get covered by frost, debris or snow as per the weather conditions. Cleaning them up and maintaining the building’s look can be a challenge for the owners, and that is where window washers step in.

Have you ever thought about the amount of effort and stamina that goes into this activity?  Breathtaking heights and merciless cold winds are not ideal working conditions by any means. Here is a short video that illustrates the immense risk that window washers take.

Walking The Mighty Mac On Labor Day

The Mackinac Bridge, or the Mighty Mac as it is also called, is the third largest bridge of the United States. A very heavily populated crossing this bridge connects the Mackinaw City on the south to St. Ignace on the north.

A Grand Structure.

The 5 meter long bridge hosts a popular Walk on Labor Day each year. The Governor of Michigan leads the 5 mile long Bridge Walk. This tradition started as soon as the bridge was completed and opened to public in 1958.

A Grand View During The Bridge Walk.

The complex structure of the Mighty Mac was a challenge to complete for all those involved in the construction. One can imagine the risk in repairing the bridge on scaffoldings.

A Beauty In The Night!!!

Scaffold Regulations Specified By OSHA

A host of regulations have been set up by OSHA in order to outline the safety standards to be maintained in scaffolding work. Here is a brief preview of the regulations since the original makes for extensive reading which is time consuming and cumbersome. Broadly the regulations can be classified in the following sub heads if not more:

  • Types of scaffolding: There are two types recognized by OSHA viz. supported scaffolds rising from the ground upwards and suspended scaffolds those hanging with the help of cables.
  • Load capacity: Scaffolds should be able to take their own weight plus four times the maximum load requirement.
  • Scaffold Platforms: In order to protect any falling through intermittent space, scaffold platforms must not have more than one –inch space between side-by-side sections.
  • Guard Rails: This is mandatory at each level of the scaffolding structure on all sides.
  • Foundation: The legs of the scaffold must rest on firm and solid foundation constructed under expert supervision.

What Are Stair Towers?

Most of the scaffolding structures, need internal stair towers for easy access of the heights.  Complex scaffoldings are not easily navigated and stair towers work to help with that. These are created by combining high quality stair, landing and guardrail components which are used in scaffoldings.

Landing platforms are used at regular intervals in case of cross stair towers and the height of scaffolding determines the number of landings in the structure. Stair towers have many advantages the most important one being that they increase the security quotient of the work environment. It is not only easy to navigate people but also heavy building materials. Stair towers might stretch the entire length of scaffolding height or maybe used only at a few levels in the scaffolding structure.

The diagram here illustrates a typical plan employed in stair tower construction.

Scaffolders: A Peek Into Their Rare Working Conditions

Scaffolding can be both thrilling and pleasurable a job if the workers are made to work in structures hoisted on national buildings or architectural marvels. Imagine watching the world move from an aerial perch atop the Lincoln Memorial, the US Capitol Dome or the Jefferson Memorial. Usually when work is undertaken on these buildings, the milling throngs do not realize the presence of scaffolding spidermen at the greater heights until it is pointed out to them.

Scaffolding under a Bridge!!

What would a scaffolding worker feel when he is working at a Bridge renovation? Imagine being all geared up with harnesses and height gear and taking a break in between work? All you would get to see is the smooth movement of vessels carrying people and materials passing below you. Working into the chilly nights could get you a rare view of sunsets which no one can ever imagine. The back-breaking job gets a much deserved boost from these few breaks coupled with fun filled moments on the risky perches. Get to know more about such dares by our workers at Scaffold Resource.

The Height Guard: A Tool To Edge Protection In Scaffold Work

When laborers are at work in a scaffolding set they are usually protected by a guard rail that is ideally placed at a height of two feet at each level. However, there are times when a scaffolder climbs to a higher level before the establishment of the guard rail. This is usually when the new level is being installed in the scaffolding set up.

The height guard is an edge protection system that ensures edge protection in the absence of the guard rail. It can be lifted from a lower level to the next level before the scaffolder has climbed up. It is a triangular structure designed to extend between two consecutive levels by taking the support of a guard rail in the lower level to give edge protection to a climbing worker in the next level. Check out the working of this height guard in the video here.

Take a Look Beneath the Surface

Disneyland has always been a source of fun and excitement to people all over the world. This popular amusement park usually ranks at the top of the list when people are touring the US. But have you wondered about how the buildings, rides, and other structures are maintained so that they look perfect all the time?

Since the park is open 24×7 on all 365 days, the repairs and construction work has to be done while the visitors are present. However, if the scaffoldings are visible, it completely spoils the theme of Disneyland by proving to be a major distraction. That is why large and oversized tarps are used for camouflaging the scaffolding. The tarps feature intricate and almost perfect drawings of the facades behind the scaffolding. It sort of creates an illusion for the visitors temporarily that they are looking at the actual façade.

This concept of using photographic tarps dates back to the time when the Emporium was being renovated. Small birds were also depicted on them to make it more realistic. Various theme parks have been using the same method successfully. Town Square Photography and Disney Clothiers are now being depicted on the tarps as they are undergoing extensive repairs.
