(3) The work commenced at 6.00am. and was completed by 3.30pm, when all electricity supply was restored to normal operation. The total time taken was 9.5 hours.
(4) A total of 19 crew members were involved in the works. The crews on site for the duration of the work, 12 people in all, were;
a two person underground crew, which undertook the excavation, cable installation and site restoration;
a three person electrical fitters crew, which carried out the the installation of all the substation switchgear, and connection and disconnection of temporary supply cables;
three two person cable jointing crews which carried out the jointing and termination of all the cables; and a backhoe (one person), which excavated the site;
Another seven people attended the site as needed during the course of the work, these were:
a two person overhead line crew, which was responsible for the disconnection and reconnection of cables located on poles;
two single person operator crews, which undertook all switching to isolate and reconnect the electricity within the area of works;
a two person crane truck crew, which delivered materials and equipment to the site, and removed them when the work was complete; and one foreman who was responsible for the supervision of the total works
(5) The work was undertaken on the Saturday to reduce the number of interruptions to businesses, schools and residential consumers supplied from the substation.
Cook Primary School and Preschool were without supply for the duration. Saturday provided no disruption to their operations.
Offices adjacent to the Cook Shops including the Assemblies of God Church were without supply. Doing the necessary work on Saturday minimised any disruption to their operations.
Cook Shopping Centre had to be isolated. Saturday proved to be the best time for the work to be done, both for the traders and for ACTEW. ACTEW installed a temporary generator to meet the reduced Saturday electrical demand of the shopping centre.
Parts of Sections 15 and 20 of Cook, supplied from the substation, were temporarily supplied from adjoining circuits. Saturday, with a more evenly distributed load pattern compared to weekdays, enabled the redistributed electrical load to be adequately met.
