Score for this attempt: 20 out of 20 Submitted Oct 29 at 10:05pm Dear Students: This is your Homework Quiz 7. Like previous Homework Quizzes it will be graded on a pass-fail basis and we have set it up so that all questions will be graded automatically. Accordingly, you will get your grade right after you submit your work. NOTE that you will see the correct/incorrect answers at that time, but you will see these only ONCE so take a screenshot if you care to have them for later review. You can then assess whether or not to take the test again. 15 out of a total of 20 points will earn you a "pass." A pass will earn you 5 points out of a maximum of 55 points for assignments, team exercises, etc. You may repeat taking this test up to three times before the final due date to earn a "pass." This time, there are no separate PDFs to be uploaded. Best wishes, Prof. T Take the Quiz Again

Concepts and Definitions For each definition, identify the term that best matches it. When improving the resource requirement profile of a schedule, move activities to start at another time by reallocating TF or FF, or extending the schedule duration. Note that this can be particularly challenging when resources are scarce and there is resource contention. Resource leveling A network of activities with precedence relationships, where activities are specified with their durations, as well as the type and number of resources they need. Resource-loaded sche A 'typical' estimate of how long an activity may take Normal duration of an Characteristic of an activity network, that a shorter project duration can have a lower total project cost Time-cost tradeoff Expenses that are tied to work items (e.g., subcontracted work) Direct cost Compensation paid by the contractor to the owner in Liquidated damages

You may come up with several different schedule alternatives. Some of the possible solutions are shown in the following table: Schedule 1 Schedule 2 Schedule 3 Schedule 4 Schedule 5 Schedule 6 Schedule 7 A starts at 0 A starts at 0 A starts at 0 A starts at 0 A starts at 0 A starts at 0 A starts at 0 B at 0 B at 4 B at 0 B at 0 B at 7 B at 4 B at 0 C at 5 C at 0 C at 5 C at 5 C at 0 C at 0 C at 5 E at 10 E at 10 E at 10 E at 10 E at 12 E at 11 E at 11 F at 9 F at 9 F at 9 F at 9 F at 4 F at 9 F at 9 G at 11 G at 13 G at 12 G at 13 G at 13 G at 12 G at 13 2.1 Analyze each schedule alternative and decide if it keeps the project duration as short as possible while also respecting the daily resource constraint ( "Feasible" ) or if it does not ( "Infeasible" ).

Resource Leveling... 2.2 Identify from a 'traditional CPM' and from a resource perspective which activities are ‘critical’ and which ones are ‘not critical’. In a schedule that is NOT resource loaded (a 'traditional CPM'), activities are CRITICAL in case, if scheduled at their early start date and delayed, they would delay the overall project completion. A chain of activities that are critical is called the CRITICAL PATH, from there also the name “critical path scheduling” or CPM. Now consider a schedule that IS resource loaded. Resource critical extends the definition of critical. Activities are RESOURCE CRITICAL in case, if scheduled at their early start date and delayed, they would delay the overall project completion. This situation occurs when the number of available

Resource Leveling... 2.4 Assume that you are the general contractor who will deliver the scope of work per the owner's requirements. In response to the owner's request you prepared the project budget and the schedule without resource loading and communicated both to the owner. The owner and you agreed on the scope of work, the schedule, and the budget including an overhead rate of $500 per day, and then signed the contract. With work underway, the owner now initiates a change order to add scope to the work in activity F . As a result, F will now take 4 days and require 5

The owner will gladly pay you for the extra day of work and all the extra workers needed to complete F. Given the maximum resource level as specified earlier, is this fair compensation? Yes No 1 / 1 pts Question 6 Continuing with question 2. Resource Leveling... 2.5 What could you reasonably ask for (in number of additional days) in terms of your schedule's duration? Write 0 if you do not need a time extension, or state how many days you need. 2 1 / 1 pts Question 7 Continuing with question 2. Resource Leveling... 2.6 In addition to the amount the owner has agreed to pay you, what could you reasonably ask for (in additional money) in terms of your project's budget? Write 0 if you do not need additional money, or state how much money you need. When answering, please round to the nearest integer and omit the $ sign e.g., for $21,344.29 write 21,344

Crashing the Schedule ... Assume that activities can be crashed as indicated in the table below. The total project cost (including direct costs, overhead costs, and the bonus or liquidated damages) for the network diagram in 3.1 as scheduled is $100,000. Overhead costs are $500 per day. The owner had projected this project should take only 30 days and you are incurring liquidated damages of $1,000 per day for every day past the 30-day specified project duration. You will receive a $1,000 per day bonus for completing the project in less than 30 days. The minimum allowable overall duration of the project is 24 days.

Use the table provided to present the values you used to derive your answer. When filling out the "Crashed activity(ies) column, please write the activity name + how many days it is being crashed e.g., if at first activity X is being shortened (crashed) by 1 day, write X1 If subsequently activity X is being shortened (crashed) by another day, write X2 Continue likewise for additional days. NOTE: shorten the duration by only 1 day at a time. If two or more activities are being crashed at the same time, e.g., if activity X is being crashed 2 days and at the same time activity Y is being crashed 1 day, write X2Y1 When filling out the "Crashing cost" and "Total project cost" columns, please round to the nearest integer and omit the $ sign e.g., for $21,344.29 write 21,344 Project duration Liquidated damages Overhead savings Crashed activity(ies) Crashing cost ($) Total project cost ($)
