How do schedule and claims consultants effectively show time when presenting their cases? A typical schedule analysis will rely on Time Impact Analysis bar charts that show activities represented by bars spanning months of time. A bar chart can be effective in providing an overall view of a delay, however it does not effectively illustrate the impact of small culminating delays. With the help of applications like Adobe Flash whose framework is built on timelines, consultants can easily develop a model of the project as it’s built without the experience necessary to use 3-D modeling software. Below are some 2-dimensional examples of exhibits built on timelines in Adobe Flash.
Example No. 1: Caisson and Grade Beam Installation Time-lapse
Delay to Caisson Installation due to Obstructions and Interference
This time-lapse illustrated the time between when each caisson was drilled and finally poured with concrete. The contractor encountered numerous issues such as movement of adjacent structures, steel redesign, and obstructions. Caissons would turn green when drilled and as time elapsed, the colors would change based on the number of calendar days passed. Once the caisson was complete, a black dot would appear in the caisson. Caissons that were red, purple and gray took the longest to complete. This color system gave the contractor a sense of where the impacts affected productivity the most.
Example No: 2 Window and Curtain Wall Installation Time-lapse
Delayed Material Deliveries from Window Supplier
The window wall material delivery time-lapse illustrates the haphazard delivery of window wall materials required for window installation. The window installers contract called for windows to be installed on a floor-by-floor basis. The time-lapse of deliveries illustrated that the manufacturer failed to deliver the materials necessary to complete the window installation of a floor-by-floor basis.
Example No. 3: Micropile Drilling Time-lapse
Out-of-Sequence Drill Rig Movements
Micropile drilling time-lapse illustrating the movements of each drill rig, out-of-sequence movements, obstructions, abandoned piles and piles on hold due to RFIs. The contractor on this project anticipated drilling every other pile and did not anticipate the large jumps from pile to pile.
