Our supply chain management model ensures we select and appoint the best suppliers who are both responsible and capable of delivering for our customers.

To maintain the right calibre of suppliers within our supply chain, potential suppliers must be follow one of two pre-assessment routes:

1) Via the Achilles BuildingConfidence accreditation scheme. This is our preferred option. However, we now accept all recognised Common Assessment Standard (CAS) bodies and their associated accreditation schemes (click here to learn more).

2) Via the Costain materials, plant or subcontract pre-qualification questionnaire completed through our Supplier Relationship Management system (SRM).
