Today Construction News revealed the performance scores of Network Rail’s top contractors.
The contractors made up 45 of Network Rail’s 87 suppliers and joint ventures to have received a PRISM score across the 15 reporting periods up to 24 February 2018.
The PRISM score is a measure used by Network Rail to monitor the delivery performance of its contractors.
Companies are scored between one and five on a number of different performance criteria, including delivery on time, engineering assurance, health and safety, contract administration and behaviour.
Suppliers must be working on a contract that is three months or longer and has a value greater than £50,000.
In Network Rail’s full suppliers list (see table below), Bridgeway Consulting and CCS Computer Science came top of the list, both scoring a perfect 5 for the periods covered.
Cumbria-based Story Contracting was the highest-ranking contractor with an average score of 4.91 across the period.
Network Rail’s top-performing consultants included CH2M, which scored 4.89; Arcadis, with a score of 4.51, and Capita which posted a score of 4.47.
The average score for Network Rail’s suppliers was just over 4.00, with the lowest score over the period being Morgan Sindall’s 2.47.
