The challenge
With the passage of time and the updating of regulations, a number of speed signs within the Chelsea area needed to be replaced. Running from Latchmere No.3 to Imperial Wharf – and incorporating Chelsea River Bridge – much of the signage in this area was deemed to be life-expired, whilst other signs did not align with the implementation of a new speed limit over the bridge.
Amaro was instructed to amend the existing signage, relocating a number of signs, whilst installing new models as per the signal sighting forms supplied by the client.
The solution
Working under a master test plan, Amaro’s new works testers, installers and civils teams delivered the planned works over the course of three weekends utilising pre-planned possessions. Whilst the
first two possessions were both 8 hours in length, allowing for a degree of survey and preparatory works to be undertaken, the third was 27 hours long, and included the installation of a number of larger speed signs requiring 4.5m posts to be dug into the cess.
Given the nature of the works and the increased risk of a cable strike, all buried service plans were obtained and studied carefully prior to breaking ground. Further EML/CAT scanning was carried out
throughout the works and a ‘dig with caution’ policy was strictly implemented.
The outcome
All signage was successfully installed, sighted, and handed back into service at the end of the third possession with all documentation signed off by the Tester in Charge.
