Pre-qualification standard 2021
As of March 2021, an updated industry-wide pre-qualification (PQ) system has become operational. Its purpose is to simplify a complex system for the benefit of everyone in the construction sector. The modified Common Assessment Standard (CAS) should reduce the duplication of time, effort and resources that are costing the sector up to £1 billion a year.
Major contractors and clients – including Balfour Beatty, Costain, HS2, Mace, Multiplex and Skanska – have all adopted the CAS. This means that members of their supply chains will need to obtain just one certification to tender for work with them. This follows the implementation of a data sharing solution which enables contractors and clients to obtain key PQ data from any one of three recognised assessment bodies: Achilles, CHAS or Constructionline.
The CAS is an industry-agreed question set with two levels of certification – desktop and site-based – and companies can apply to any recognised assessment body to get the appropriate level dependent upon their trade, size and requirements of their clients.
Created by Build UK (of which ECA is a key member) and with the support of CECA, the CAS is endorsed by the Construction Leadership Council (CLC), which is actively seeking its adoption throughout Government construction procurement, including the Construction Playbook.
Paul Reeve, CSR Director of ECA and deputy chair of the Cross-Industry Body, said, "Data sharing paves the way for increased specification by main contractors and other buyers and offers suppliers more choice about who carries out their pre-qualification assessment. It will also help to deliver the savings and efficiencies that the supply chain has long been looking for, by reducing the need for multiple PQ questionnaires and schemes."
Andy Mitchell, Chair of the CLC, said, “It is a real and practical way of reducing bureaucracy and improving quality in the industry and it comes at just the right time. Companies will be able to demonstrate that they meet an agreed industry standard, and clients and contractors will be able to rely on the certification.”
