A small project is composed of seven activates whose time estimates are listed in the following table. Activities are indentified by their beginning $($i$)$ and ending $($j$)$ node numbers.

a$)$ Construct the Precedence Diagram Method Network $(5$ mark$).$

b$)$ Convert the activity on the node diagram into activity on arrow diagram $(5$ mark$).$

e$)$ Determine the CP and the total completion time of $($a$)$ and $($b$)$ and what could you conclude from both $($show the table$)(10$ mark$).$

d$)$ Activates $A,B,C,D,E,F,G,H,$I,$J,K$ are completed $100\%$ what is the remaining time for this project to be deliver? What could you as construction or project engineer conclude from this number? $(10$ mark$)$

e$)$ What is the different between PDM and CPM $(5$ mark$).$
