The solution
The team followed an intense risk assessment process to understand the differences in hazards between:
- Replacing a pipe in a trench
- UV curing to extend the life of a pipe
The risk assessment showed that typically, the lining of pipes has a lower risk than installing pipes in trenches.
A two-fold solution was reached, in which curing by UV light was used to extend larger pipes, whilst smaller pipes were replaced with new pipes in trenches.
The process resulted in a £21 million saving to the client.
By using this alternative method, the team were able to incorporate the following benefits
Confined space entry and lifting operations eliminated
Less traffic management operations required
Work near overhead power cables reduced
Manual handling prevented through use of laser cutting operations
