A2Z was started by Amit Mittal in 2002. Initially the group began its operations in facility management, maintaining telecommunications towers for Vodafone India, reliance. Later, in 2008, it entered the engineering, procurement, and construction EPC (contract) business. The EPC business expanded with the acquisition and merger of Sri Eswara Sai Construction Private Limited, a company that installed transmission lines, in January 2008. A2Z later transferred its FMS business to its wholly owned subsidiary, A2Z Infraservices in the same year pursuant to a court-approved scheme of demerger. In August 2009 A2Z acquired Imatek from the same FMS industry. In May 2010, A2Z's EPC business signed a contract to purchase the entire business of Surendra Choudhary & Brothers, a partnership that constructed electrical substations and did railway electrification work.
