SOLUTIONS MARKED A+
✔✔resource leveling - ✔✔smooth the use of resources
✔✔resource constraints - ✔✔after resource constraints are added to a schedule the
project duration will be longer than before
✔✔cash flow analysis - ✔✔disbursement and receipt of funds for:
-labor
-materials
-equipment
-subs
✔✔increase in project duration - ✔✔always leads to increase of project indirect cost
✔✔False - ✔✔project monitoring and project control are the same concept
✔✔cost account - ✔✔-scope of work
-resource
-time
-accountability
✔✔linear schedule - ✔✔appropriate for projects where activities are repetitive
✔✔reasons for planning scheduling and control - ✔✔-size
-complexity
-fragmentation
-control resource consumption
-communicate construction plan
✔✔Bar Charts - ✔✔simple and time scaled presentations that show how major work
activities are scheduled
✔✔advantages bar charts - ✔✔simple and easy to use
✔✔disadvantages bar charts - ✔✔-cannot determine project status
-cannot determine needs for adjustments
-activites for acceleration cannot be determined
-relies on extra links to show logical relationships between activities, otherwise
relationships cannot be determined
✔✔networks - ✔✔graphic representations using nodes and links
-CPM
, -PERT
✔✔basic network concepts - ✔✔-activity
-event
-duration
✔✔activity - ✔✔discrete part of project that can be identified for planning, scheduling,
monitoring, and controlling the construction project
✔✔Event - ✔✔point in time or an instant at which the status or completion of a project
or an activity can be defined
✔✔Duration - ✔✔the period of time that will be consumed in completing a task
✔✔milestones - ✔✔particular point in time for reference or measurement. do not
consume and time or resources
✔✔arrow diagrams vs. precedence diagrams - ✔✔-both use network presentations to
represent activities, logic, times, and duration
-both support critical path
-arrow diagrams use links to represent activities and nodes to represent events; while
precedence use links for relationships and nodes for activities
✔✔CPM vs. PERT - ✔✔-both use network presentations for activities, logic, times, and
durations
-both critical path
-CPM has determined activity durations, while PERT has 3 estimated times
✔✔steps to develop network model - ✔✔1. define activities
2. order activities
3. establish activity relationships and draw network diagram
4. assign durations to activities
5. assign resources and costs
6. calculate early and late start/finish times
7. compute float values and identify the critical path
8. schedule activity start/finish times
✔✔forward pass calculation - ✔✔early activity times and project duration
✔✔backward pass calculation - ✔✔late activity times
✔✔lag - ✔✔the difference between the early finish of the activity preceding the link and
the early start of the activity following the link
