You are working on a project to build a bridge. You have reached the planned halfway mark. The total planned cost at this stage is $500. The actual physical work that has been completed at this stage is worth $400. You have already spent one thousand dollars on the project. What is the CPI?
Preliminary cost estimates are developed during the __________ phase of the project.
Cost baseline is usually represented using which curve or line.
By completing a forward pass a project scheduler can...
calculate the free float for each activity
calculate the total float for each activity
score a touchdown
find the critical path
A contractor with an Experience Modification Rate (EMR) of 0.9 regarding accident claims will most likely pay more than the industry average for worker's compensation insurance.
You are planning to use PERT for planning of your project. A task has pessimistic estimate of 24 days, most likely estimate of 15 days, and optimistic estimate of 12 days. What is the mean using the PERT technique?
The critical path is the set of events that cannot be delayed without causing an extension of the project
____________ is the number of days that an activity can be delayed without extending the project minimum duration.
_________________ is the amount of money added to the base estimate to account for risk and uncertainty
IN 1970, the federal government began a process of providing a comprehensive set of safety rules and regulations, inspection procedures, and safety record-keeping requirements. OSHA was established at this time. OSHA stands for:
Occupation Standards and Health Agency
Observe Safe Highways Always
Outside Safety and Health Administration
Occupational Safety and Health Administration
The typical construction worker's (craftwork) productive versus nonproductive time can be broken down by percent of time to the following
If BCWS=1000, BCWP=1200, and ACWP=1300, the project is...
Ahead of schedule and under budget
Ahead of schedule and over budget
Behind schedule and over budget
Behind schedule and under budget
Which activity-to-activity relationship model is assumed when creating a critical path method network diagram?
Start to start
Start to finish
Finish to start
Finish to Finish
A rough order of magnitude estimate is made during which phase of a project?
A construction project has a schedule performance index (SPI) of 1.19 and a cost performance index (CPI) of 0.88. Which of the following is the best explanation for why this occurred?
Unfavorable work conditions
Labor rates too high and critical path changed
Overstaffing of work
Non-critical path activities took less time and cost 12% less
Project expenses paid by the owner to pay for payroll services provided by the contractors home office is what type of cost?
Direct field cost
Indirect project cost
None of the Above
If BAC (budgeted at completion) for a work package is $10,000 and BCWP=$4,000, the the work package is...
40 percent complete
80 percent complete
100 percent complete
120 percent complete
When a project is completed, which of the following must be true?
BAC = ACWP
BAC=ETC (estimated cost to complete)
If BAC=$24,000, BCWP=$12,000, ACWP=$10,000 and CPI=(BCWP/ACWP)=1.2, then the cost that remains to finish the project is...
Cannot be determined
To control the schedule, a project manager is reanalyzing the project to predict project duration She does this by analyzing the sequence of activitie with the least amount of scheduling flexibility. What technique is she using?
Critical path method
Work breakdown structure
You are the project manager of a construction project. The original scope baseline of the project was budgeted at $100,000. Since work on the project start, there have been seventeen authorized and approved changed to the project. The changes have a value of $17,000. There is also an additional change order for $2,500 that has been paid but not yet approved by the owner. What should you report as the current budget for the project?
During the project life cycle, in which part of the life cycle will risk be the lowest?
In critical path scheduling, total float is calculated as the sum of an activity's early start and the late start (TF = LS + ES)
Cost Performance Indicator is an index showing the efficiency of the utilization of the resources on the project. Cost Performance Indicator can be calculated using the following formula: CPI = Actual Cost (AC)/Earned Value (EV)
According to the Association for the Advancement of Cost Engineering (AACE), Class 2 cost estimates are developed during the ___________ phase of the project.
What are the best uses of PERT?
Used in the planning phase to do "what if" scenarios for the project.
Assist in the controlling of changes to the project.
Is used in the process of preparing a WSB for the project.
To measure future consequences of activities.
A & D
Activities with little total float are called "near-critical" activities, because they can quickly become critical if their small amount of total float is used up in a delay.
A proper Work Breakdown Structure includes:
Physical components of the final constructed product.
Activities required to construct the final product that do not directly build a physical component.
Both physical components of the final constructed product and activities required to construct the final product that do not directly build a physical component.
The responsibilities of specific project organizations or people for specific wok packages.
None of the above
The Spearin doctrine is a legal principle that holds that when a contractor follows the plans and specifications furnished by the owner, and those plans and specifications turn out to be defective or insufficient, the contractor is not liable to the owner for any loss or damage resulting from the defective plans and specifications.
According to CVEN 349 lecture and the text, forecasts of future costs can be uncertain due to
Forecast errors due to economic conditions
A & B
All of the Above
For most construction activities there may be no direct relationship between elapsed time, actual work, and incurred costs?
A cost performance index (CPI) of 0.89 means
At this time, we expect the total project to cost 89 percent more than planned
When the project is completed, we will have spent 89 percent more than planned
The project is only progressing at 89 percent of that planned
The project is only getting 89 cents out of every dollar invested
An Organizational Breakdown Structure (OBS) can include
Activities required to construct the final product that do not directly build a physical component
Both physical components of the final constructed product and activities required to construct the final product that do not directly build a physical component
The responsibilities of specific project organizations or people for specific work packages
