- 1. Royal Border Bridge - Viaduct Refurbishment
-
Royal Border Bridge is a 28-span masonry arch viaduct, which carries rail traffic over the River Tweed and forms part of the East Coast Main Line.
The structure is Grade I listed. It had been identified that the structure was suffering from defects such as loose brickwork, open joints, parapet leaning/bulging, fractured pattress plates and other minor works areas typical of masonry.
Our customer was contracted on behalf of Story Contracting and Network Rail to deliver a major intervention repair scheme designed to rectify all defects and ensuring this important piece of infrastructure is able to operate reliably and is safeguarded well into the future.
HAKI Access Solutions were awarded the access supply contract to design and install a bespoke access scheme to get our customers abseiling team out to the required repair areas.
- 2. Tay Road Bridge - Underdeck Access
-
During the summer months of 2023/24, our customer VolkerLaser was working with the Tay Road Bridge Joint Board to carry out restoration works to Tay Road Bridge, a key transport link connecting Fife to Dundee.
Since its construction in 1966, the bridge has faced decades of wear and tear, and exposure to the harsh Scottish elements, and the time had come for the road deck to receive a well-earned refurbishment.
In addition to the repair and resurfacing of the road deck, there were multiple areas of the underdeck soffit requiring repairs to the concrete. HAKI Access Solutions were awarded the contract to supply the underdeck access required to complete these repairs.
- 3. Forth Rail Bridge - Temporary Maintenance Gantry
-
The Forth Rail Bridge is an iconic cantilever bridge constructed in the 1880’s and spanning the Firth of Forth just North of Edinburgh. It continues to remain a significant and admirable engineering structure of the Victorian era.
- 4. Forth Road Bridge - Truss End Links
-
During routine inspections of the Forth Road Bridge by the operator, a crack in the pivot of one of the truss end links was discovered in late December 2015. This resulted in the bridge, one of the main transport links in the area being closed over the festive period and lengthy diversions.
The changeout of the affected steelwork took 18 months to complete, largely slowed down by the traditional scaffolding having to be continually modified to react to the changing work scope and with the scaffolders impeded with a lack of suitable steelwork for their connections into the structure.
Roll into 2017 and Transport Scotland decided to change the remaining seven end links as a precaution. The Spencer Group were awarded the contract, and they contracted HAKI Access to design, engineer and install a bespoke access system for their project.
