St Julian’s Viaduct was constructed in 1885 and is used to transport people over the River Usk by train. It is located in a rural area of Newport, South Wales. Due to its location, our main concerns were the access to the site and how we would be able to take deliveries of the heavy plant required to carry out the works. Once this issue was resolved, we then had to source equipment powerful enough to supply ample pressure to our blasting equipment.
In order to win the competitive tender bid, Hankinson EPIC had to demonstrate our experience in projects of a similar nature and produce the relevant industry certification and occupational health records of our employees. 
The main works on the underside of the bridge and parapets were carried out from a fixed scaffolding that was then encapsulated. We had to satisfy the Environmental Agency that all had been done to ensure that no debris from our works could enter the River.
The Columns of the Viaduct were accessed via a barge and painting could only be carried out during short windows of opportunity as the tides controlled when we could apply the coatings.
Our works package included applying a polysulphide mastic to the back to back lattice bracings to ensure moisture could not enter the rear of the bracings resulting in corrosion.
As the bridge had been previously painted in Lead based paints, CLAW regulations (Control of Lead at Work), had to be adhered to at all times. Samples of the existing Lead coatings had be sent away for analysis to determine the percentage of Lead remaining on the bridge, to ascertain the levels of Lead that our Operatives had the potential to be exposed to, and to ensure that the waste generated by the works was disposed of correctly by a licensed Waste Management Company
Before works commenced all Operatives had to have Lead blood level tests carried out, to see how much Lead was currently in their body. They would then undergo further testing every 4 – 6 weeks to monitor exactly how much Lead was finding its way into their bloodstream.
A lot of time and money was spent on training our Operatives, as anyone working on the project had to be ICATTS approved, attend the Network Rail Personal Track Safety Course and have lung function tests, in order to be issued with a Face Fit respiratory mask, to comply with Network Rail safety requirements.
Hankinson EPIC’s Site Painting Inspector also had to be trained to achieve the Nace Level 2 qualification
Daily climatic temperatures had been checked every 3 hours to ensure that all works were being carried out in line with the Specification.

Works to trackside parapets had to be planned and carried out on nights under approved Network Rail Possessions.
