Questions and CORRECT Answers
crtical path - CORRECT ANSWER - the longest continuous chain of activities through the
network schedule that establishes the minimum overall project durations.
Critical Path Characteristics - CORRECT ANSWER - -Longest path through schedule
-must have a start and end date
-path is continuous through to the end of the schedule
-Convergence: activities have more than one predecessor
-Divergence: activities have more than one successor
Early start / Early finish - CORRECT ANSWER - Early Start (ES): The earliest an activity
can be started after all predecessors to the activity are completed.
Early Finish (EF): The earliest an activity can be finished given that activity's early start and
duration.
Late Start/late finish - CORRECT ANSWER - Late Start (LS): The latest an activity can
be started after all predecessors to the activity are completed.
Late Finish (LF): The latest that an activity can be finished and still complete the project within
the minimum overall duration determined by the forward pass.
Forward pass - CORRECT ANSWER - the process of navigating through a network from
start to end and calculating the early start and early finish dates for each activity and the finish
date for the entire project.
Goal: calculate the early start and finish dates
Result: what is the total project duration?
Backwards Pass - CORRECT ANSWER - the process of navigating through a network
from end to start and calculating the late start and finish dates. these dates determine the critical
activities, critical path, and the amount of float each activity has.
, goal: determine the LS & LF dates for each activity
result: what is the critical path of a project?
Slack/Float - CORRECT ANSWER - A number that indicates the amount of time a task
can be delayed without impacting subsequent tasks or the project's overall completion.
Task Slack = Late Start - Early Start
Task Slack = Late Finish - Early Finish
Most Owner contracts will dictate the duration of float that is required within the schedule.
Preconstruction activities - CORRECT ANSWER - -linear process of getting an acceptable
price
-Design activities
-Review of task list
-Procurement Activities
-Common Challenges (permits, cranes, community impact, etc)
-long lead items
Site logistics plan - CORRECT ANSWER - the sequencing and movement of materials,
people, and resources on and around construction sites
Uses of site logistic plan - CORRECT ANSWER - -safety
-transportation efficiency
-worker efficiency
-material handling
-security onsite
-inventory control
-housekeeping
-communication/coordination
