As the works were carried out during the winter months the new boilers and associated plant had to be installed in phases so as to maintain partial services. This allowed the majority of the works to be carried out within normal working hours except for the plant movement and change overs which were carried out over weekends and evenings which also ensured the safety of the client’s personal. The works included a number of specialist sub contractors all of whom had to be coordinated to ensure that the works ran smoothly and on time.
