Final Exam Chapter 9-13 Flashcards
what is a gantt chart
uses bars to show length of each activity
easy for clients to understand and follow since it relates to calander days
doesent show relationships with arrows between activities
what is a network diagram also known as
critical path method (CPM)
what is a network diagram
shows relationships duration and float
does not provide the visual clarity that gantt charts have
what are some other types of schedules and what type of work are tehy used for
matrix = highrises
line of balance = roadways
horse blanket = transit systems
what do you look at to choose the type of schedule
size of company volume of work type of construction project size project complexity computer capabilitis contract requirements
what is a detailed schedule
breaks major activities down into smaller tasks so the overallschedule can be analyzed further
what is summary schedules
groups activities under broadheadings ie. sitework foundations
what are mini-schedules
a portion of the detailed or summary schedule that is broken down into even finer detail
what are short interval schedules aka
look ahead schedules
what are short interval schedules
crated by supers or foremen to coordinate and manage work over a short period of time typically 3 weeks
what is a special purpose schedule
keeps track of activities that support the work ie. delivery, submittal
what do you use to make sure you have all the activities needed to mangae the project
work breakdown schedule
what questions do you ask in the sequencing stage
what other activities must be completed first
which activites can start when this one ends
which activities can occur simultaneously as this activity
what are the basic rules to follow for determining durations
evaluate each activity as an independent operation
consult with subcontractors to get their time estimates
assume a standard crew size for each activity
adjust production rates to fit the job conditions
use a standard 8 hour day
can the critical path change throughout the project
yes
what are the two most common types of schedules
gantt charts and Network diagrams
what are the 2 techniques to make network diagrams
AOA
AON
what does AOA stand for
the Activity is On the Arrow and Nodes show relationships
what does AON stand for
Activity is On the Node and arrows show relationships
What is AON also known as
Precedence Diagramming
what are 3 different types of activities that are included in a typical schedule
Production= physical construction work. install steel in concrete procurement= obtaining materails and equipment administrative= inspections, submitals, testing
what is float also known as
slack
what are the 3 calculations that you perform to ge thte project float
forward pass
backward pass
float calculation
what does the forward pass calculate
the early start and finish
what does the backward pass calculate
the late start and finish
what are the 3 stages of network diagram development
planning= what needs to be done sequencing= in what order scheduleing= how long does each task take
what are the steps to teh project control cycle
develop project plan establish the estimate and schedule monitor the project performance identify performance deviations evaluate corrective options make adjustments as needed document report and evaluate results
what is essential at the end of every project
a debriefeing and evaluation stage
what are some factors that impact project performance
weather conditions quality of the work force quality of supervision incorrect sequencing of work change orders overcrowded jobsite defective materail inadequate tools and equipment late deliveries
what ae the primary tools used to track quality
plans and specs
what ae some administrative tests
field observations submittals shop drawings mock ups inspections
what do you use to track project cost
a cost code
what is a cost code
a refrence number used to track cost and schedule info on project costs
