CASE STUDY: delivering cares accredited precast solutions for hs2
Details
Client: EKFB, Joint venture between Eiffage, Kier, Ferrovial Construction and BAM Nuttall, delivering civil engineering works for HS2
Project Type: Design and Supply of Precast concrete drainage products.
the challenge
EKFB, the delivery partner managing significant civil engineering works for HS2, required a highly credible precast concrete supplier capable of meeting demanding criteria around product quality, traceability, sustainability, and timeline reliability. The project demanded:
- Precast concrete products manufactured to stringent HS2 quality standards
- Full CARES accredited supply‑chain traceability for steel reinforcement
- Compliance with strict government‑led auditing frameworks
- Sustainable manufacturing approaches aligned with HS2’s environmental targets
EKFB needed a trusted supplier that could demonstrate industry‑leading standards, certification capability, and long-term reliability.
the solution
To meet these needs, EKFB turned to specialists in water management and drainage products, who then engaged their long‑standing manufacturing partner JKH, with whom they have collaborated for more than 30 years. JKH brought decades of experience in the production of high‑quality precast drainage infrastructure.
As part of the solution JKH supplied precast elements manufactured using their ECO1 low‑carbon concrete mix, helping reduce embodied carbon while still meeting all durability and performance requirements in accordance with BS 8500.
To meet HS2’s compliance requirements, JKH committed to achieving full CARES accreditation, enabling complete traceability of steel reinforcement from source to final product.
This collaboration ensured that EKFB received fully compliant, sustainable, and traceable precast products from a dedicated and proven supply chain.
key STEPS
JKH undertook a comprehensive program of audits, system reviews, and quality process improvements to achieve CARES accreditation. Key steps included:
- Close collaboration with CARES auditors throughout a rigorous audit schedule
- Enhancements to quality control documentation and traceability systems
- Completing cover meter surveys and supplying reports confirming cover concrete cover to steel reinforcing.
- Stocking non-standard parts specifically for HS2.
- Internal audit cycles conducted to CARES standards
Through the commitment and expertise of the JKH team, CARES accreditation was achieved in just six months, a timeline that drew high praise from the auditing team and demonstrated the company’s capability and readiness for major infrastructure supply.
the Results
The successful collaboration between EKFB and JKH delivered several key outcomes:
- CARES accreditation achieved, unlocking supply eligibility for HS2 and future government infrastructure schemes
- Full supply‑chain approval for handoffs
- Ability to supply pre-cast concrete products with CARES accredited reinforcing.
- Demonstrated alignment with HS2 expectations around sustainability, quality, and traceability.
- Enhanced competitiveness for future public-sector tendering opportunities
EKFB benefited from a robust, transparent, and sustainable supply chain supported by two trusted partners working in close alignment.
