Determine the critical path and expected duration for this project. 2. What is the earliest the project could be completed if tasks were \"crashed\"? 3. What is the least additional cost required to achieve the completion date you determined in Question 2? 4. Suppose that the promised completion date for the project is week eight, and that the construction manager faces penalty charges of $10,000 per week if the actual completion date is later than eight weeks. What project duration minimizes total project costs (normal activity costs + penalty costs + crash costs)
