The purpose of this report is to illustrate the processes and functions with respect to the Bridgeguard 3 (BG3) Programme involving the inspection, assessment, protection and enhancement of Network Rail owned public road-over-rail bridges as a result of the UK Government’s agreement to allow 40T/44T Heavy Goods Vehicles (HGV) for international journeys on UK roads.
The report outlines the origins of BG3, from the initial European Council Directive and the UK Governments decision to undertake a risk management exercise to address the situation of allowing unchecked increases in HGV’’s since 1968 from 24T to 38T, through the challenges faced and ahead in order to close-out this massive enhancement operation.
Covering issues which caused delay in commencing the enhancement scheme, along with management and financial obligations by the stakeholders, the general impact of 40T/44T HGV’’s on bridges and safety responsibilities. Requirements will also be discussed with respect to inspections and working in the railway environment. Moving on to explain the assessment process, interim mitigation requirements, feasibility studies for works options such as permanent mitigation, which may involve permanent protection and/or strengthening or reconstruction. Then will examine the roles and responsibilities of the BG3 Coordinator plus a walking through a case study to illustrate the labyrinth of related tasks and decisions involved from receiving an assessment result through to a permanent solution that is acceptable to all stakeholders, both economically and in a practical sense relating to transport, environment and public interactions.
Finally, the current expenditure and status will be scrutinized in order to predict a date and cost of completion of the National BG3 Programme based on, and extrapolated from, the progress of the South East Territory.
