It is the first time in the system’s 11-year history that material suppliers have been invited to submit their pre-qualification questionnaire data alongside its already 21,000 strong register of contractors and consultants.

The online portal, which is used by over 2,400 clients from across the private and public sectors, provides buyers of construction services with access to real time PQQ information on suppliers.

The move comes in response to overwhelming demand from Constructionline’s clients for greater access to PQQ data across the construction supply chain.

Philip Prince, a director from Constructionline, said: “Our clients are increasingly being expected to deliver projects with less time and money available to them.

“Completing and processing PQQs are necessary stages of the procurement process but they can quickly become burdensome if managing the data becomes difficult and time-consuming.

“By creating an integrated source that incorporates material suppliers and contractors we are allowing buyers to access PQQ information from across the supply chain in one place, reducing the amount of resources needed to successfully manage each project.”
