Actavo, formerly Siteserv,[1] is an industrial and engineering services company headquartered in Dublin, Ireland.
[2] It has several divisions which provide events management services, modular buildings, scaffolding, fencing, safety equipment and telecommunications networks.
[3][4] Originally known as Siteserv, the company was acquired by Denis O'Brien in March 2012.
[5] The sale of the company was the subject of significant controversy as Irish Bank Resolution Corporation (IBRC, formerly Anglo Irish Bank) wrote-off €119 million owed by Siteserv prior to its sale.
[6] The commission's report, published in September 2022, found that Siteserv had provided "misleading and incomplete information" to IBRC.
