Approximately 60% of the work was planned to begin in January, including MCC fabrication, new cabling and cable racks. The MCC and I/O panels were fabricated off-site and the company supervised FAT testing to ensure that the equipment would be ready for commissioning upon delivery. Where possible, new instruments were also installed, but were only switched on at commissioning.
