Assume you have been asked to build a storage building for a charitable organization that you assist. They have some donated supplies arriving at the end of 15 working days and desperately need the room in the storage building you are building to store them. If you are unable to complete the storage building project in the 15 working days, it will end up costing the charitable organization (or you, if you feel guilty enough about it) $100 per day for each day the project takes longer than 15 working days (because there will be a cost for storing the donated supplies on the rental truck that is being used to deliver them). Information related to this project is as follows:

ID Description Predecessor Time (days)

A Pour Foundation None 3

B Erect frame A 4

C Roof B 4

D Windows B 1

E Doors B 1

F Electrical B 3

G Rough-in Frame C,D,E,F 2

H Door Opener E,F 1

I Paint G,H 2

J Cleanup I 1

REQUIRED:

1a. What is the Early Finish (EF) time for the last (right-most or right-hand) activity in the project network?

1b. What is the name and the ID of that activity?

2. What is the Late Start (LS) time for activity G (the Rough-In Frame activity)?

3. What is the amount of Slack (SL) for activity D (the Windows activity)?

4a. What activities are on the critical path(s)? (List from earliest to latest by both ID and Activity Name (Description)). (Hint: the easiest way to display all of the requested information may be to create a table containing it. Be sure to provide all the requested information in the order it is requested.)

4b. What is the total length (in days) of the critical path?

5a. Will the project be done before the end of the 15 working days? (Yes or No)

5b. If not, for how many days will the $100 per day of storage on the truck have to be paid and

5c. what will be the total cost for storage?

NOTE: If questions 5b and 5c are not applicable because the answer to question 5a was "Yes",

then simply write "Not Applicable" for each of questions 5b and 5c as your response.
