Specialist Capabilities Phi Group offers design, supply and installation of gravity and reinforced soil retaining walls, with integrated solutions across ground improvement, piling and adjacent structures. This presents opportunities to jointly bid on complex civil engineering and ground engineering projects requiring turnkey wall systems and interface details.

Parent Company Backing Operating under Keller’s umbrella, Phi Group benefits from a broader portfolio and financial backing which can support larger, multi-faceted projects and increases credibility when pursuing sizable tenders or long-term framework agreements.

Project Scale Potential Current project values range from modest to substantial (£1,000 to £1m+), indicating flexibility to engage across a spectrum of project sizes. Sales conversations can target both small-scale wall installations and larger ground engineering schemes that require integrated design and delivery.

Tech and Workflow Adoption of modern tech such as AWS, iCIMS, Drupal, DocuSign and OpenAI suggests readiness for digital collaboration, data-driven design, and streamlined procurement and contracting processes. Leverage these capabilities to propose efficient project onboarding and secure, paperless bids.

Market Positioning With a focus on gravity and reinforced soil walls and vegetated slopes, Phi Group is well positioned to win projects where sustainability, erosion control and interface integration with existing structures are critical. Targeting public works, transport, utilities and infrastructure modernization opportunities could yield high-fit opportunities.
