$.(50)$ A contractor has $30$ workers on the construction site for a specific task, which is

behind schedule $(2$ weeks delay$).$ They work $8$ hours work and $5$ days per week based on

$$15$ hourly salary. The liquidate damage is $$2,000$ per day. You should show the

calculation process to get full credits $(10$ points$)$

A contractor needs to make a decision whether the schedule should be accelerated based

on the overtime work $(12$ hours per day and $5$ days per week$)$ or just leave the schedule.

Overtime payment is $2$ times of the base hourly salary. What is your choice based on the

expected value?

$($Hint: You need to consider the overtime payment as well as the lost value on your

productivity. Then you can compare total expected lost value and total liquidate damage

for delay$)$
