Erskine Bridge Lighting and Electrical Refurbishment

The 22-week contract encompassed comprehensive external and internal refurbishment across the entire bridge structure. External works included replacement and upgrading of road lighting installations on both bridge approaches, deck-mounted lighting systems, high mast luminaire replacement with associated electrical network upgrades, and installation of intelligent road lighting management systems. Critically, all external works required night-time execution to maintain daytime traffic flow across this vital transport link.

Internal works within the bridge’s box girder structure demanded specialist ATEX Category 2 approved electrical systems suitable for potentially explosive atmospheres. Our scope included removal of six 100mm steel cable conduit pipes, installation of 300mm heavy gauge post-galvanised ladder rack systems, supply and installation of 679 ATEX Cat 2 LED luminaires with integral emergency lighting backup, and installation of 17 internal lighting distribution boards plus 17 street lighting distribution boards.

Phase Two focused on replacing twin-armed columns mounted on the bridge deck whilst upgrading all existing lanterns to LED technology. Working with Mallatite to manufacture bespoke flange-plated columns designed to utilise existing deck foundations, we eliminated costly and time-consuming foundation replacement works. This innovative approach enabled completion of 27 column replacements in just five nights during August 2016, with a further nine replacements achieved in a single night during October. At the summit of both 40-metre towers, we replaced aircraft obstruction lights and associated cabling with new LED units. Originally scheduled across two daylight weekends to comply with aviation safety requirements, our teams completed this challenging work in just one weekend, substantially reducing disruption to the travelling public.
