Dynamic Consortia Model

The framework can be used with a Dynamic Consortia Model, allowing Triflex to assign each project to the most suitable approved contractor via the B2G DPS.
This ensures clients benefit from manufacturer-led design and warranty assurance, while a vetted contractor handles on‑site delivery
This model provides:
  • Access to the right contractor for every project, as DPS members can join at any time
  • Reduced procurement overhead and greater flexibility than fixed consortium arrangements
  • Integrated delivery assuring optimum efficiency and compliance
