To maintain the right calibre of suppliers within our supply chain, potential suppliers must 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 (learn more about the schemes here).
2) Via the Costain materials, plant or subcontract pre-qualification questionnaire completed through our Supplier Relationship Management system (SRM).
