Works Dashboard indicators

At a glance, like in a car dashboard, you can have a look at the work progressing in each worksite. The indicators Timing Advancement and Work in Progress indicate the passing of time and the work progress. Their ratio, the Potential Delay Index (PDI), may be either positive or negative: works are more advanced or lags behind compared to the expected duration of the worksite.

i.e. the works at the Zero Pavilion have already consumed 25% of the envisaged work days, whilst the state of progress is at a standstill, subsequently the PDI is at the red bottom.

The Removal of Interferences on the perimeter of the area has used up all available days, and approximately 15% still falls behind the target fixed for final delivery. PDI is slightly negative however within the green area.

The three indicators are calculated on the basis of these definitions:

• the overall index of Timing Advancement (TA) is given by the ratio between the worked days that have been dedicated to the works as a whole so far, and the total number of days according to the implementation contracts. It shows how much work has been done so far compared to expectations i.e. if it indicates 50% it means that up to present date half the number of the calendar and consecutive days foreseen for conducting all works have actually passed by. It is updated on a weekly basis.
• the overall index of Work in Progress is the ratio between the sum of all Work in Progress Stages (WiPS) issued according to the most recent monthly update concerning all works, and the total amount envisaged for their carrying out, including approved variants. This index shows, in a reliable manner, the overall work in progress since WiPS are given by the exact calculation of all carried out processes. It is updated on a weekly basis.
• the Potential Delay index (PDI) is given by the ratio (WiP/TA)-1. It shows to what extent the work in progress is in line with the passing of time. A negative value (indicator shifted on the left-hand side) indicates that the percentage of the overall progressing of works is lower than that of the days actually worked. On the contrary, the index shifted to the right-hand side shows that the percentage of actual work in progress is higher than the percentage of time passed by.

The data used in the visualization of the “Works Dashboard” refers to both the information provided by the worksites and validated by Expo2015 S.p.A. , and to the dataset “Dashboard Data” published in the open data catalogue.
