AGC, the AmcoGiffen and Carnell partnership, have successfully delivered another parapet renewal for National Highways. The M621 Gildersome interchange parapet replacement scheme was completed in August 2023 through the Scheme Delivery Framework (SDF) contract, for which AGC are the Road Restraint Systems lot provider in the Yorkshire North East region.
With the parapet having reached the end of its serviceable life, 240m of N2W1 vehicle parapet was removed and replaced, along with the associated transitions to the existing verge vehicle restraint system (VRS), in eight locations.
As principal contractor, AGC delivered the scheme in collaboration with Jacobs (principal designer), and HW Martin (traffic management). The programme of works was carried out over four phases on both the clockwise and anti-clockwise carriageways of the M621. Working with sector scheme approved manufacturer Versco and National Highways’ safety and engineering standards division, the technical approval process for the temporary and permanent works approvals was navigated, to achieve the desired programme start and completion dates.
