Question $4(25$ marks$)$

The following situation consists of eight activities for a construction project and shown in table Q$4$ below. The activity duration, the resource hours needed for carrying out the activity, and the relationship among activities are clearly defined.

Table Q$4$ below shows the Activities, Durations, Resource hours required per week, and Predecessors for Sample Project

Table Q$4$

$($a$)$ Assume that Activity B and Activity C are scheduled that require the same resources $($equipment$)$ at the same time. Use any one of the heuristic logics to decide which activity should receive the first priority for the required resources.

$(2$ marks$)$

$($b$)$ Explain the concept of Resource Levelling and create a time$-$phased Resource$-$loading table for this project.

$(7$ marks$)$

$($c$)$ Assume that the maximum resources hours available per week are $10.$ Which weeks are over$-$committed?

$(4$ marks$)$

$($d$)$ What options are available to Resource$-$level the project? Recreate the Resource$-$loading table.

$(6$ marks$)$

$($e$)$ Assume that the maximum number of resource hours per week that can be committed to this project is reduced to $7.$ How would you reconfigure the Resource$-$loading table to adjust for this number?
