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:
Outside Safety and Health Administration
Occupation Standards and Health Agency
Observe Safe Highways Always
Occupational Safety and Health Administration

30/70
50/50
75/25
40/60

A rough order of magnitude estimate is made during which phase of a project?
project executing

Critical path method
Flowchart analysis
Precedence diagramming
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?
114,500
100,000
119,500
117,000
During the project life cycle, in which part of the life cycle will risk be the lowest?
Closeout
Planning
Initiation
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.
Bid
Budget Authorization
Feasibility
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:
Both physical components of the final constructed product and activities required to construct the final product that do not directly build a physical component.
None of the above
The responsibilities of specific project organizations or people for specific wok packages.
Physical components of the final constructed product.
Activities required to construct the final product that do not directly build a physical component.
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
Technology changes
Forecast errors due to economic conditions
Analysis Errors
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
