Figure 1.
The layout shows four panels stacked vertically with a shared horizontal time axis from April 2016 to April 2019. The first panel titled provisional programme shows a schedule with tasks Structural frame from about July 2016 to August 2017, Envelope from about March 2017 to April 2018, Fit out from about August 2017 to September 2018, and Commissioning from about December 2017 to September 2018. The second panel shows Electricity consumed with the left vertical axis labelled Electricity demand megawatt hour from 0 to 800 and the right vertical axis labelled Electricity demand kilowatt hour per square metre from 0 to 12.78. Monthly values increase from about 50 in August 2016 to around 200 by late 2016, then rise steadily to about 400 by mid 2017, reaching peaks near 700 to 750 between January 2018 and April 2018, followed by a decline to about 200 by late 2018 and near 50 by early 2019. The third panel shows Hours worked with the vertical axis labelled Hours from 0 to 2.5 multiplied by 10 to the power 5. Values start near 0.5 multiplied by 10 to the power 5 in mid 2016, increase to around 1.0 multiplied by 10 to the power 5 by early 2017, rise further to about 1.5 multiplied by 10 to the power 5 by late 2017, peak between about 2.0 and 2.3 multiplied by 10 to the power 5 during early to mid 2018, then decrease to below 1.0 multiplied by 10 to the power 5 by late 2018 and near 0.2 multiplied by 10 to the power 5 by early 2019. The fourth panel shows Concrete delivered with the vertical axis labelled Concrete cubic metre from 0 to 5000. Values begin around 2000 in mid 2016, increase to about 3000 to 3500 by late 2016, peak near 4000 to 4200 in early 2017, then fluctuate between about 1500 and 3000 through mid 2017, before dropping below 1000 after late 2017 and remaining mostly below 500 through 2018 to early 2019.Provisional programme, electricity demand, hours worked and concrete deliveries at Site A during the project from August 2016 to February 2019
