Whar Our Clients Say


Deputy Executive Director Commercial, Sydney Metro

“Adrian displayed excellent leadership qualities in this role including mentoring and guidance of more junior commercial staff and as part of a strong Senior Management group, through the various challenging circumstances encountered by the project, including COVID-19, unprecedented wet weather, complex design interface issues and Industrial Action.”

Senior Partner, Sydney Law Firm

“Adrian’s written work is excellent – his reports require little refinement driven by the fact that he can explain complex technical concepts using simple and easy to approach language. Responsiveness and extremely fast turnaround time, particularly when we have very tight court timetables. Adrian works well with not only senior lawyers and Partners, but also junior solicitors and Associates – this is a rare quality for an expert of Adrian’s experience and calibre. Adrian engages with feedback on his reports in a positive and constructive manner. Adrian collaborates extremely well and is a pleasure to work with, even on the most complex and long running matters.”

Partner/Owner, Sydney Law Firm

“During the time that I have known Mr Jamieson, I have always found him to be a highly organized, articulate and efficient operator, performing the services I have engaged him to provide to a high standard and on time (often with tight deadlines). I also value Mr Jamieson’s calm, approachable and professional demeanour.”

Former TfNSW Project Director, Sydney Growth Trains Project

During this time he provided excellent support and management in the following areas:

  • Leading, managing and developing a high performing commercial team;
  • Negotiating complex commercial agreements and resolution of contractor claims;
  • Developing successful working relationships with internal stakeholders, train operators and project delivery contractors;
  • Budget reporting, cost control and participation in various senior management forums.
  • Was a key member of my senior management team and became a trusted advisor on commercial and strategic matters; and
  • Acted in my role as Project Director while I was on leave and during that time was responsible for achieving final sign off to enable the first train to enter passenger service.
    His work was a major factor in the successful delivery of the Sydney Growth Trains Project.”
