Question 7. Project Crashing and Activity Delays (20 pts) (15 pts) You are considering completing this project in the shortest time possible. What is the fastest the project can be completed, and the associated costs of that approach (without incurring any unnecessary costs)? Your solution must indicate the step by step (one week at a time) order and duration of the 'crashing' of activities so that the company President can choose their preferred combination of cost and schedule. Indicate incremental crash costs and total costs for fastest project completion. After preparing a crashing table as above, answer the following questions: a. (3 pts) After the project was progressing at normal times, the subcontractor ran into problems completing the building exterior. One of the two on-site cranes had a hydraulic failure and replacement parts had to be ordered and installed. This meant that all lifting during that time had to be completed by a single crane resulting in a two-week delay for completing the building exterior. If you want to complete the project in the original "normal" time, what specific actions must you take to minimize costs while still completing the building as originally scheduled? Justify your answer. b. (2 pts) Hoping to open the store exactly one week before Friday of Labour Day long weekend, the company President has asked if the grand opening could possibly occur? Why, or why not?s to construction of other About Coffee stores a information provided by potential subcontractors, you have developed the followin chart with estimates for normal durations and normal costs, in addition to crash cos and crash times, in the event it would be necessary to accelerate a specific activity.

The weekly increase in costs for a given activity is assumed to be constant
