Scope of Work

The scope of the software provision and technical support includes, but is not limited to, the

following:

• Provision of multi-seat annual lease licenses for 3D finite element analysis (FEA) software or integrated suite capable of:
  • Evaluating soil and rock mechanics, 3D excavation design, tunnelling, support design, and groundwater seepage.
  • 3D stability analysis software for evaluating underground excavations in jointed rock and modelling intersecting rock wedges.
  • Graphical and statistical analysis tools for orientation-based geological data, stereonet plotting, and kinematic analysis of rock slopes.
  • Analysis of rock and soil strength data, failure criteria evaluation, and material property determination.
  • Integration of data from geological and mine planning software for numerical model building
• Delivery of software licenses via a Cloud/Online License management system, with full administrative privileges granted to Trinity Metals for independent user management. Local servers and physical dongles will not be accepted.

Eligibility and Competency Requirements

Interested parties must:

• Be an established developer or authorized provider of globally recognized geotechnical engineering software, with demonstrated application in hard rock underground mining environments.
• Provide software products that natively integrate and interoperate (e.g., importing material properties into numerical models, exporting joint orientations into stability analysis modules).
• Ensure the software suite is fully compatible with standard corporate IT environments, specifically Windows 64-bit systems.

• CVs of proposed personnel for technical support clearly demonstrating rock engineering/geotechnical engineering numerical modelling proficiency and technical IT support.
• Summary of at least three similar software supply contracts undertaken in the last five years, including client name, project scope, and contactable references.
• Certificate of domestic company registration issued by RDB.
• VAT registration certificate
• Valid tax clearance certificate issued by RRA.
