Lecture 10 Flashcards
Bar or Gantt Chart
* __________ ___________ of project activities in a time- scaled bar
line with no links shown between activities
* Can involve ____ multi hierarchical information: break
components into activities/tasks
* Document _____ and ____ time of each activity
* Loaded with resource or _______ numbers
graphic presentation, WBS, start, end, budget
Bar chart (Gantt chart) can show resource usage: __-_____
S-curve
Gantt charts can show _______ ______, by schedule vs. _________, and ____________
resource usage, actual, milestones
Bar Chart (Gantt Chart)
Advantages:
– Powerful ____________ tool (visual/graphic representation of the process of construction)
– Easy to ______ and quickly grasp
– Can see the _______ and big picture of the job
– Simple way to schedule small projects
– No extensive _________ needed
– Summary display of more ________ projects (e.g., milestones, progress)
– Good for upper management,
subs, workers, equipment…
management, read, overview, training, detailed
Bar Chart (Gantt chart)
Disadvantages:
– Activity ______________ not clearly shown, does not identify “Sequence” logic
– Hard to relate individual activity _____ to overall project completion
– Hard to identify the _______ activities in complex projects
– Difficult to ________ for large, complex projects
– Not automatically show the effects of ______
dependencies, delays, critical, maintain, changes
Fence Bar Chart
* A bar chart developed from a ____ that shows the logic flow of __________ among activities in Bar Chart shape.
* Graphically show the relationship among the ____________ & successors
CPM, relationships, predecessors
“S” Curve Schedule
* An s-curve is a ______________ graph that depicts relevant __________ data for a project (such as cost or man-hours) plotted against time
mathematical, cumulative
S-curves are used for different purposes. Some of the most common uses of S-curves are for _______ and performance
evaluation, ____ flow forecasts, _______output comparison, and _________ range of possibilities.
progress, cash, quantity, schedule
Line of Balance (LOB)
* A management control process used in construction where the project contains
blocks of _________work activities, such as roads, pipelines, tunnels, railways and
high-rise buildings.
repetative
Line of Balance (LOB)
* Show repetitive work as a ______ line on a graph.
* Unlike Bar Chart, it shows the ___________ rate/speed of activities that has to be
undertaken to _____ on schedule.
single, completion, stay
Line of Balance (Linear) Schedule
* Line of Balance (LOB) is a management control process for collecting, measuring and presenting facts relating to ____, _____
and _______________
* The purpose is to ensure that the _________ activities stay “in balance” - they are producing at a pace which allows an even
flow of the items produced through a process and at a _______ compatible with the goals set forth in a plan
time, cost, accomplishment, repetitive, speed
- Unlike a Bar Chart showing the ________, a LOB Chart shows the ______ of all activities,
duration, rate
Line of Balance (LOB) Advantages
– Allows a _______ understanding of the amount of work taking place at a certain time and place
– Optimizes __________ for a large number of repeated work activities
– Is relatively easy to ________ and update
– Better for management of subcontractors and resources
clearer, resources, change
Line of Balance (LOB) Disadvantages
– Critical path ________ be determined, focuses more on single activity
– It is labor __________ and expensive
– No _________ to automate the generation of LOB
cannot, intensive, software
