Company Founder and Senior Consultant

Chris Rowbotham is the founder of Landale Consultants.  He has over thirty years experience in the IT industry with particular emphasis on real-time and mission critical systems.  He received his Bachelor of Engineering from the University of NSW in 1975.  The early part of his career involved the analysis, design and project engineering of large mini computer based control systems.  Over the subsequent fourteen years with the company he held a number of senior positions.

In 1981 Chris joined Australia’s largest SCADA company as a Software Engineer.  After moving to the position of project engineer/team leader, with responsibility for all aspects of project implementation and delivery, he assumed the role of Software Manger, with overall responsibility for company projects and project teams.  He was then appointed to the position of Technical Director with responsibility for the company’s product development and its engineering output.

In 1989 he was appointed to the Board  and served on the Board until a group restructuring in 1992 and subsequent management buy-out of the company.

In July 1995, Chris founded Langdale Consultants Pty. Ltd. as an engineering and consulting company providing services primarily to Utility companies.  The major services provided by the company are consulting and software design, development and support.  Chris remains active in both the consulting and software development sides of the company.  His skills span strategic planning, systems architecture, systems specification, systems design, procurement and vendor management.

Chris has worked with a wide variety of companies and state owned corporations both in Australia and overseas.  These include Endeavour Energy, Country Energy, Powercor, CitiPower, Sydney Catchment Authority, Railcorp, Midlands Electricity and E-ON.


Chris’ goal for the company is to assist organisations to maximise the benefits that they derive from their operational systems and to ensure that maximum value is obtained from each and every project in which the company is engaged.  In most cases this involves the combination of a clear strategic vision with a pragmatic and flexible approach to systems design and integration.
