PERT

Question 1

are recently developed numerical techniques which construction management can use as an aid in planning, scheduling and controlling the building of any type of project.

Answer 1

Critical path method (CPM) and the project evaluation & review technique

Question 2

Each operation of a project is performed in only one way.

Answer 2

CPM I

Question 3

Alternate methods are considered for performing some or all the operations of the project.

Answer 3

CPM II

Question 4

is the deciding of WHAT should be done.

Answer 4

Planning

Question 5

is the determining of WHEN operation should be done.

Answer 5

Scheduling

Question 6

was developed in the late 1950s by Morgan R. Walker of DuPont and James E. Kelley Jr. of Remington Rand, Kelley and Walker related their memories of the development of CPM in 1989.

Answer 6

a project modeling technique

Question 7

is a widely used project management tool that uses network analysis to help project managers to handle complex and time-sensitive operations.

Answer 7

Critical Path Analysis (“CPA”)

Question 8

is a step-by-step project management technique for process planning that defines critical and non-critical tasks with the goal of preventing time-frame problems and process bottlenecks.

Answer 8

Critical Path Method (CPM)

Question 9

chart is a project management tool used to schedule, organize, and coordinate tasks within a project.

Answer 9

PERT (Program Evaluation Review Technique)

Question 10

involves setting the objectives of the project

Answer 10

Planning

Question 11

Based on the time estimates, the start and finish times for each activity are worked out by applying forward and backward pass techniques, critical path is identified, along with the slack and float for the non-critical paths.

Answer 11

Scheduling

Question 12

refers to analyzing and evaluating the actual progress against the plan. Re allocation of resources, crashing and review of projects with periodical reports are carried out.

Answer 12

Controlling

Question 13

can be replanned, rescheduled and resources for them can be reallocated flexibly, without affecting the whole project.

Answer 13

Non-critical activities

Question 14

is a graphical process which management can use as an aid in planning and scheduling operations in a project.

Answer 14

Critical Path Method

Question 15

is a graph of operations

Answer 15

CPM

Question 16

is called a DUMMY OPERATION.

Answer 16

Dashed Arrow

Question 17

requires no time. It is merely a device to identify a dependence among operations.

Answer 17

Dummy Operation

Question 18

The CPM graph for the project is called the ARROW NETWORK. It is constructed on an “operation-by-operation” basis

Answer 18

Arrow Networking

Question 19

represents an action and consumption of resources (time, money, energy) required to complete a portion of a project. Activity is represented by an arrow

Answer 19

Activity

Question 20

will always occur at the beginning and end of an activity. The event has no resources and is represented by a circle

Answer 20

Event

Question 21

The direction of the arrows on the lines indicates the sequence of tasks. The task between nodes 0, 1, 2, 4 & 5 must be completed in sequence.

Answer 21

DEPENDENT or SERIAL TASKS

Question 22

The task between NODES 1 & 2, NODES 1 & 3 are not dependent on the completion of one to start the other and can be undertaken simultaneously. The tasks are called

Answer 22

PARALLEL OR CONCURRENT TASK

Question 23

Tasks that must be completed in sequence but that don’t require resources or completion time are considered to have event dependency.

Answer 23

Dummy activities

Question 24

are nodes and represent events or milestones.

Answer 24

Numbered rectangles / circles

Question 25

represent dependent tasks that must be completed sequentially.

Answer 25

Directional arrows

Question 26

indicate possibly concurrent tasks.

Answer 26

Diverging arrow direction

Question 27

indicate dependent tasks that do not require resources.

Answer 27

Dotted lines

Question 28

One or more activities can start and end simultaneously at an event.

Answer 28

Merge and Burst Events

Question 29

Activities performed before given events

Answer 29

preceding activities

Question 30

activities performed after a given event

Answer 30

succeeding activities

Question 31

is the spare time available when all preceding activities occur at the earliest possible times and all succeeding activities occur at the latest possible times.

Answer 31

TOTAL FLOAT

Question 32

is the spare time available when all preceding activities occur at the earliest possible times and all succeeding activities occur at the earliest possible times.

Answer 32

FREE FLOAT

Question 33

an activity is the duration that it can slip without delaying the next activity or the project end date

Answer 33

Float (also known as Slack)

Question 34

in a network schedule diagram is the network path with longest total duration

Answer 34

Critical path

Question 35

is laying out of the actual jobs of the project in the time order in which will have to be performed.

Answer 35

Scheduling

Question 36

is also called a Gantt chart since it was developed by Henry Gantt in 1920s.
- It is one of the most popular and widely used techniques for planning and scheduling activities because the graphical representation of a bar chart makes it easy to read and understand

Answer 36

BAR CHART

Question 37

chart uses arrows and lines to tie the activities and subsequent items, specifying the successors and predecessors of every activity.

Answer 37

linked bar

Question 38

is fine for manual computation

Answer 38

Project time

Question 39

which converts project days into calendar dates is very useful.

Answer 39

Project calendar
