considered in the assessment.
Data used in the Assessment
Construction Staff Numbers and Shift Patterns
12.23 It is expected that the construction period will see the peak of vehicular activity at the site.
Construction is anticipated to take approximately 9 months commencing in Q1 of 2012.
12.24 Standard construction hours are expected to be from 0800 to 1600 hours Monday to Friday, with a
10% allowance for working from 0800 to 2000 hours Monday to Saturday.
12.25 The construction period will comprise of two phases. The first phase relates to preparation of the
site and construction of site infrastructure. The second phase relates to the process plant fit out,
testing and commissioning. It is likely that Phase 2 will run in parallel with the last two to three
months of Phase 1. For the purpose of this assessment it has been assumed that Phase 1 will run
in parallel to Phase 2 during months 7, 8 and 9 of the construction phase.
12.26 At present it is understood that there will be varying degrees of staffing levels across the nine
month construction period. The Phase 1 construction workforce is expected to peak during the
middle of the construction period, with an average workforce at this time of 22 and a maximum of
26 construction workers being present on the site. The Phase 2 construction workforce will be at
its highest during the last month, with an estimated average workforce of 23 construction workers
on the site. If Phase 1 runs in parallel with Phase 2 there could be a maximum of 38 workers on
site.
