The project requires a crane that rents for $800 per week and a crew of general labour that cost $4500 per week. Ahead of the next project team meeting, the project manager has tasked you to develop the project schedule along with relevant analysis on possible cost savings related to completing the project ahead of schedule.

For the questions that follow, use the activity codes in place of the activity. For instance, activity B should be written as activity 2. That is, 2 stands for B. Thus, a critical path of say, CBJ must be written as 3210 in the space provided.

Note: All answers must be in numeric form, This is why activities are given number codes.

i. The latest start time for activity J in order to complete the project on time is Blank 1. Fill in the blank, read surrounding text. .

ii. The number of weeks for which activity B could be delayed without delaying the project is Blank 2. Fill in the blank, read surrounding text. weeks.

iii. The project completion time is Blank 3. Fill in the blank, read surrounding text. weeks.

iv. The critical path of the project (in terms of the activity codes, and in the right order) is Blank 4. Fill in the blank, read surrounding text. .

v. The total cost of the project within the normal time frame is $ Blank 5. Fill in the blank, read surrounding text. .

vi. The activity/activities to crash in order to take advantage of weekly indirect savings as far as it makes economic sense is activity/activities Blank 6. Fill in the blank, read surrounding text. . Please answer using the activity codes and in the order from minimum to maximum activity code.

vii. The total cost of the project if the action in question (vi) is carried out is $ Blank 7. Fill in the blank, read surrounding text. .

viii. If the project has to be completed in 40 weeks, then the activity/activities to crash when at week 41 in order to achieve the 40 weeks (using activity codes, and listing the smallest first) is Blank 8. Fill in the blank, read surrounding text. . Please answer using the activity codes and in the order from minimum to maximum activity code. For example, if the activities to crash to get to week 40 when on week 41 is C,I, provide the answer as Blank 9. Fill in the blank, read surrounding text. .

ix. The minimum total cost of the project if it has to be completed in 40 weeks through crashing is $ Blank 10. Fill in the blank, read surrounding text.
