Evaluation of All-Round Modular Scaffolding (ARMS) type Scaffold by using BS1139 Standards for Industries

Abstract

Scaffolds can be categorised into access scaffolds and support scaffolds based on its functions: access scaffolds and support scaffolds. Regardless, both are only consent to be used when it follows requirement set forth by the government in order to protect the workers’ safety and health. Due to increased demand for scaffolds manufacturers try to compete with each other by developing various type and sizes of scaffolds. Unfortunately, the usage of these modern scaffolds such as All-Round Modular Scaffoldings are rather limited due to its deviations from the BS 1139 standards. This study aims to determine the distribution force on the All-Round Modular Scaffolding determine its suitable duty category based on the BS1139 guidelines. Standard parts of ARMS from manufacturer was used to build one storey x 1 bay (sizing 3 m x 3 m) structure and was assembled by authorised and professional contractor. The structure was then put through load test. The load was placed on top of the working platform and the deflection of the components was measured. The findings reveal that the structure as well as the individual platform can support loads up to 500 kg with no crack or permanent deformation observed after the test. By referring the BS1139 standards, the All-Round Modular Scaffolding is surpassing the requirement for general and heavy-duty scaffold with distributed load on platform recorded to be 2.67 kN/m² and concluded that the additional length of the components does not compromise the working purpose of the scaffolds.
