[edit] Philosophy
Marr designs innovative cranage solutions and works with contractors to address complex construction and engineering challenges.
By working closely with contractors, Marr aims to find the most efficient, productive and safe cranage solution for the project. The best results are delivered when Marr is consulted early in the front-end engineering design stage of the process.
[edit] Heritage
Marr is a third-generation family-owned and run business.
Founded in 1926, Gordon Robert Marr designed one of Sydney’s first cranes to make it easier for his father’s iron foundry business, E.A. Marr & Son, to transport the heavy parts required to recondition boilers for their client, Colonial Sugar Refinery (CSR).
During the ‘space race’ of the 1950s and 1960s, the company was nicknamed by industry peers as ‘The Men From Marr’s’.
Gordon Ernest Marr took over the company in the early 1970s, instilling a culture of ‘doing things differently’. This was during the same period as Australia’s resources boom, the Sydney 2000 Olympics, and many of the city-shaping projects that Australia is known for.
Gordon Ernest Marr also established Marr’s partnership with crane manufacturer, Favelle Favco.
The third generation started when the current managing director, Simon Marr, took over in 2000. Since he started working in the business at the age of 17, he had worked his way up through the business. Simon has overseen Marr’s expansion into new sectors and international markets, including Southeast Asia, Turkey, the UAE, Latin America and the UK.
Simon’s brother, Gordon John Marr, is technical & product development director.
In 2021, Marr Contracting International opened an office in London and a regional office in Leeds, United Kingdom, in 2024.
