Question: Based on the following project information, you are asked to:

(a) Prepare AOA network

(b) Using PDM, calculate activity information (ES, LS, EF, LF, TS and FS) and determine critical path activities.

Note: For all activities, assume FS dependency with no lag

\begin{tabular}{|c|c|c|c|} \hline Activity & Duration (days) & ImmediatePredecessor(s) & Early Start (ES) \\ \hline START & 0 & - \\ \hline A & 10 & START \\ \hline B & 7 & START \\ \hline C & 5 & A, D \\ \hline D & 4 & B \\ \hline E & 6 & B \\ \hline F & 3 & E \\ \hline G & 5 & D \\ \hline H & 9 & C.G \\ \hline K & 4 & F, G \\ \hline L & 2 & K \\ \hline FINISH & 0 & H,L \\ \hline \end{tabular}
