• Senior Mechanical Engineer on various sewage pumping systems with capacities from 2 to 6 Cumecs. Typical mechanical budgets $3 to $10 million
• Fletcher Construction does not undertake mechanical or Electrical works, and therefore although my title was as a Mechanical Engineer my predominant function was to manage subcontractors and budgets to deliver works on behalf of the company.
• Led investigations into machine failure, both of plant purchased by the company but also of equipment purchased from 3rd party suppliers.
The objective in all cases was to identify causal failure mechanisms, where possible identify and supervise repair requirements. In all cases the objective was to gather sufficient evidence to provide the legal team with means to seek damages from suppliers.
