The document provides an overview of project management and construction scheduling, outlining various project phases, scheduling techniques like bar charts and PERT diagrams, and strategies for planning and fast-tracking construction projects to help ensure projects are completed on time and on budget. It also discusses the importance of planning, scheduling, and tracking progress to manage risks and changes throughout the project life cycle.

WHAT IS A PROJECT?
….a one-time event achieved through co-ordination
of resources to achieve specific goals or objectives.
...the process of planning, organizing and managing
the actions.
...operates within constraints of time, scope or
costs.

WHY SCHEDULE?
To tell about the plan
To set production
To track progress
To manage change
20. 20
EXAMPLE
The construction cost of a commercial building;
project duration 24 month is RM300,000,000
On average, the GC must put approximately RM
770,000 on in place each day
If annual interest rate is 9%, interest
cost for per year for RM300 million
is RM27 million!

PLANNING VS SCHEDULING
Commonly interchangeable
Planning provides overall strategy to achieve
goals
idea
Scheduling entails activities/tasks to carry out
plan
tool
24. 24
EXPEDITION & MODULARIZATION
Contractor must be capable to expedite
Supplier must also ready
Analyze workday & different shifts
Investigate possibility of continuous workday
Use modular components (IBS)
25. 25
IMPORTANCE OF PLANNING
Planning should be done far ahead of scheduling
Pre-design and design stage can drag the project
start time off limit
Allows project team to design & construct on
paper before assign resources (start)
26. 26
PLANNING QUESTIONS
Interface with existing condition
Type of delivery system
Completion date
Initial budget
Other facilities & considerations

BAR (GANTT CHART)
Popularized by Henry L Gantt & Frederick W
Taylor early 1900s for US Navy shipbuilding
Easy to prepare, read & use
No or hard to show relationship when done
manually
Now it has become useful again with the help of
scheduling software

PERT
Program Evaluation and Review Technique
Method used to compute schedule (since 1950s)
Name of a graphical technique/ display
Easy to identify relationships
Disadvantages:
Node or box size does represent duration
Not drawn on time scale
42. 42
SCHEDULING
Schedule evolves through these steps:
Milestone schedule
Bid package schedule
Construction schedule
43. 43
MILESTONE SCHEDULE
• Significant events/ highlight
– Start design
– Award contracts
– Notice to proceed
– Construction start
– Owner move-in
• Sometimes referred to as master schedule
• Set parameters then becomes detailed schedule
45. 45
BID PACKAGE SCHEDULE
An intermediate schedule
Divide milestones into different trade contracts
for bidding
Added to bidding documents, bidders have idea
about their portion
46. 46
WORK PACKAGES
Task of dividing construction work into
individual packages, which will become contract
packages to be bid out later to trade contractors.
Example:
Foundation work package (excavation, footings &
foundations) or
Excavation package, footing package & foundation
package
48. 48
CONSTRUCTION SCHEDULE
Refinement of bid package schedule
Will be used on day2day basis
Contractors are encouraged to participate during
its development
Final version sometimes called target schedule
(contractors sign-on to)
50. 50
CRITICAL PATH METHOD (CPM)
The universal method used to calculate &
evaluate schedules in construction industry
Developed in 1950s by DuPont & Remington
Need input of project information to produce
minimum project duration, start and finish time,
plus project critical path
51. 51
FAST-TRACKING
Process of beginning phases of construction
before the design is complete
When completion is 1st priority before budget &
quality. Examples:
Adding metropolitan airport extension (requires
minimal interruption to flight schedule)
New EPL football stadium (must ready before next
season starts)
Replacing the only bridge connecting 2 countries
which was damaged by earthquake

54. 54
FAST-TRACKING (CONT.)
Requires special contracting
Not General contracting
Not Single lump-sum contract
Because contractor will not commit to a locked-in price
before design is completed
Ask for cost plus fee or time&material contract
Shift budget risk to owner
Not multiple contractors for multiple phases
55. 55
FAST-TRACKING (CONT.)
Use Agency construction management
Owner award lump-sum contract to prime
contractor for different phases
Coordinated by construction manager for the
entire project
56. 56
REFLECTION
People are not taught to be any type of manager.
They are taught to perform little task, one at a
time… which is to do and complete the task
correctly. They are actually managing the task
and start to become a project manager.
