The Rise of Tier 0.5 Delivery

May 17, 2026

Provectus continues to champion a Tier 0.5 approach to remediation and enabling works delivery - operating in the space between consultancy and traditional main contracting.

Too often, projects suffer from disconnects between design, strategy, and delivery. Tier 0.5 is designed to remove those gaps.

Our model combines the technical understanding, planning, and coordination capabilities associated with Tier 1 contractors, with the agility, focus, and practical delivery mindset of a specialist contractor. This allows us to identify risks earlier, simplify project interfaces, and deliver more buildable, commercially realistic solutions.

By integrating remediation, earthworks, utilities, drainage, testing, and waste management into a single coordinated approach, we help clients:

  • Reduce programme and commercial risk
  • Improve buildability and sequencing
  • Accelerate decision-making
  • Maximise material reuse and sustainability outcomes
  • Maintain greater control throughout delivery

The Tier 0.5 model reflects how modern brownfield and infrastructure projects need to be delivered - collaborative, data-led, and fully integrated from strategy through to execution.

As projects become more complex and programmes more demanding, the need for integrated delivery has never been greater. Provectus is proud to be at the forefront of that approach.
