TTRSA is defined by an ethical approach to doing business.

  • TTRSA are always happy to discuss the specifics of projects before any commitment to proceed - clearly defining a project reduces the ultimate cost to you and risk for both parties, and avoids undertaking unnecessary or redundant work;
  • TTRSA will always be honest and truthful in discussing issues which might arise through the development and progression of a project;
  • TTRSA will tell you if our technical capabilities are not appropriate for the type or extent of work involved; and,
  • TTRSA give equally high priority to public sector and private sector work and always meet agreed deadlines. Our business is to provide and deliver a service to you.
