Notice Of Intent to carry out Boiler Refurbishment and Associated Works 2012

What are the Boiler Refurbishment and Associated Works?

Reasons for Proposal

The reasons for the works are that the boilers and plant room equipment in the boiler house have reached the end of their useful life. This is supported by the high levels of breakdowns, extent of repairs and the options Appraisal that was undertaken earlier this year.
