The construction industry has experienced fundamental changes over the past 10 years as a result of increasing trade liberalization, globalization and internationalism. The global construction industry is forecast to grow at a CAGR of 5.5 percent from 2016 to 2021, according to a report published by Lucintel. The major drivers of growth for this market are increasing rate of urbanization and growing population. Consequently, there is an increasing demand for scaffoldings in construction sites all around the world. On the downside, scaffoldings can present numerous serious hazards to employees when they are not used properly.
Types of scaffolding
A report by the Constructor defines scaffolding as a temporary structure to support the original structure. It is also used by workmen as a platform to carry on the construction works. Types of scaffolding varies with the type of construction work. Scaffolding is made up of timber or steel. It should be stable and strong to support workmen and other construction material placed on it. There are several types of scaffoldings used at construction sites. According to the report, single scaffolding is generally used for brick masonry and is also called as brick layer’s scaffolding. Single scaffolding consists of standards, ledgers, putlogs etc., which is parallel to the wall at a distance of about 1.2 m. Distance between the standards is about 2 to 2.5 m. Ledgers connect the standards at vertical interval of 1.2 to 1.5 m. Double scaffolding is generally used for stone masonry, so it is also called mason’s scaffolding. In stone walls, it is hard to make holes in the wall to support putlogs. So, two rows of scaffolding are constructed to make it strong. The first row is 20 – 30 cm away from the wall and the other one is 1m away from the first row.
“… the Bureau of Labor Statistics estimates 10,000 workers are injured every year in scaffolding accidents”
An estimated 2.3 million workers in the construction industry work on scaffolds, and the Bureau of Labor Statistics estimates 10,000 workers are injured every year in scaffolding accidents. On-site injuries and accidents cause employers to pay penalties and compensation, therefore, to prevent accidents they equip laborers with personal protective equipment (PPE), which can reduce the risks of work hazards. According to Sarah Haque, a lead analyst at Technavio, “the global PPE market in the construction industry is fueled by developments in the construction industry in APAC, Middle East, and Africa. The market is also driven by increasing focus on fall protection by the construction industry.” Technavio estimates the global personal protective equipment (PPE) market in the construction industry to grow at a steady rate and will post a CAGR of close to 8 percent during 2016-2020. The increasing demand for fall protection equipment will drive the growth prospects for the global personal protective equipment market in the construction industry until the end of 2020. Fall protection equipment such as safety harnesses, lanyards, belts and connectors, self-retracting lifelines, and guardrail systems are used in various construction sites to ensure the safeguard of employees. Also, a scaffold clamp is used to secure the fall protection equipment that supports the workers involved in activities such as maintenance, construction and repair of buildings.
