The ESB has confirmed that there has been an outbreak of Covid-19 on the construction site for its new head office on Fitzwilliam Street in Dublin. 

It said the main contractor PJ Hegarty had confirmed that four out of a total of 450 operatives are now off site, having tested positive for Covid-19. 

According to the ESB, PJ Hegarty said that three of the four had tested positive over ten days ago, and are due back at work tomorrow, while the fourth is due to return to the site on Thursday. 

The ESB also confirmed that one of 300 operatives working for the other main contractor Walls was tested for Covid-19 yesterday, and received a positive diagnosis this morning. That operative is now off site. 

The ESB defended the safety procedures on site saying: "A strict regime has been in operation at the site since the start of the pandemic, including the allocation of each operative to a designated work crew, a daily deep-cleaning regime and staggered break times to facilitate social distancing. " 

It said the contractors were liaising closely with the HSE and the Health and Safety Authority, "and remain vigilant to the health and safety of all those working on the Project Fitzwilliam site."

The 45,000 square metre Project Fitzwilliam development employs over 750 workers across a number of contractors.
