Company Overview

Company History

Robert Mann Pty Ltd was incorporated in 1992, initially to provide building services co-ordination to Leighton Contractors for Optus Projects over a 3 year period.

Following this, Robert Mann began to conduct building surveys on a number of buildings and infrastructure locations for a range of clients including NSW Department of Courts Administration, Macquarie University and NSW Agriculture. The types of buildings surveyed were varied and included anything from Sydney’s Central District Court House to Belgenny Farm, Australia’s oldest farm in Camden.

Over time the company’s focus shifted from surveying and co-ordination. In 1994 the company began trading as Robert Mann Air Conditioning, filling a market niche for specialised work in the communications industry. We completed a number of projects for major companies such as Leighton Contractors, Optus, Siemens Thiess and Transfield Services.

We have expanded our operations to meet market demand for “whole works” including building and other trades. Our project experience has ranged from mechanical services fit-out to complete building solutions including design, construction and maintenance of the building works.

We specialise in design, construction and maintenance of Data Centre facilities. Our technical expertise, fast deployment and seamless project delivery is unparalleled for maximising efficiency and maintaining your critical business continuity. Our years of experience and technical expertise, coupled with our reputation for quality service delivery, means your Data Centre isn’t just built – it’s engineered.

Our success is based on long-term relationships with our clients. We develop strong and productive partnerships on each project.

We listen to our clients to ensure we understand their projects and objectives. This is how we meet their expectations in regards to time, budget and quality.


Our service department has a number of maintenance contracts with major end users and facilities managers. We maintain Heating, Ventilation and Air Conditioning (HVAC) and other building services systems in communications, data processing, industrial and high rise office facilities.


Our hire division allows us the flexibility to maintain temporary HVAC and Power services to an existing building while upgrade work is being completed. We have maintained high rise telephone exchanges and satellite earth stations while upgrade works were carried out. We also maintained over 30 telephone exchanges from Sydney to Broken Hill with our temporary equipment while upgrade works were carried out by our staff.


Robert Mann employees are selected for their skills and expertise to provide a range of trade and professional project management services across our customer base.
