Exercise $2$

A project consisting of $8$ activities are described in the following table. The cost for completion of these $8$ activities is $5800$ excluding the site overhead. The overhead cost of general site activities is $160/$day$.$

We are asked to:

$(1)$ calculate and state the time for completion on a normal basis;

$(2)$ calculate and state the critical path on this basis, and the cost;

$(3)$ calculate and state the cost of completion in the shortest possible time.
