The COVID-19 pandemic has devastated the world of works. Its impact, which varies across sectors, has been significant in the construction sector.The construction sector has an important role to play within the overall economy of any given country. How that role manifests itself will vary greatly from one nation to another, in developing countries it is likely that the extraction of raw materials and the on-site construction activity is of most importance, as the country seeks to set up a significant infrastructure, in the form of roads, railways and buildings.Construction sector activities include the construction, renovation, maintenance and demolition of buildings (residential and non-residential), as well as work conducted in civil engineering projects such as roads and utility systems(ILO 2015).A variety of market segments are involved, including architecture and design, equipment and material manufacture, transportation, and energy and waste management. Value is added by transforming source materials into capital assets essential both for economic activity and the delivery of infrastructure services. The construction sector has its significant impact on income generation and poverty reduction. Its significant job creation potential also comes from its labour-intensive nature and strong links with other economic sectors.In the first three months after COVID-19 emerged Wuhan City, Hubei Province, China, a devastating number of new cases were reported across China and several countries around the world.
