The planning stage will always be followed by the scheduling stage to make sure that the plan will be implemented properly.

Planning stage

-Planning is a general visualization and term that sets a clear road map and logical steps that should be followed to reach a common goal or a desired destination.

-Planning includes the breakdown of the whole project into easy definable, measurable, and identifiable tasks to be established vividly and then establishes the logical interdependences among them with the necessary activities, resources, and actions to be done to reach the desired outcome without forgetting obvious and probable obstacles and the methodology of overcoming them.

Generally speaking, planning answers four important questions:

  • What is to be done and why?
  • How to do it effectively?
  • Who does it, where, and when?
  • What are the necessary tools to get things done to move on from the current to the desired and potential goal?

There are different plans with diversified levels in every field like in construction, plans exist at several levels:

  • Firstly, corporate strategic plans,
  • Secondly, Pretender plans
  • Thirdly,pre-contract plans
  • Fourthly, short-term construction plans
  • Fifthly, long-term construction plans.

Despite knowing that these plans are different from each other; however, all these plans include main steps like:

  • Identification of all activities needed for the project
  • Performing breakdown of work items involved in the project into activities.
  • Identifying the proper sequence by which the activities should be executed.
  • Activities representation.

Detailed planning for tendering purposes and the preparation of construction needs to be conducted through brainstorming sessions among the planning team. The inputs and outputs of the planning process are as follows.

  • Planning requires a rigorous effort by the planning team.
  • A planner should know the different categories of work and be familiar with the terminology and knowledge used in general practice.
  • Also, the planning team should seek the opinion of experts including actual construction experience. This helps produce a realistic plan and avoids later problems on site.

Gantt Chart or Bar Chart

As Planning Techniques in Construction Projects

The big advantage of bar chart schedules is that they are very easy to understand and follow. That’s because they can relate activities, and their durations, to calendar days. It is easy to see and understand when an activity will begin and when it will end.

The biggest disadvantage to bar charts is that they do not show the interrelationships among the activities. For example, bar charts are not very good at showing the impact that a delay in one activity might have on another activity, or on the overall duration of the project. It is not suitable for big projects.

Steps of the Planning Process

  • Identifying a complete list of activities needed to build the project.
  • Creating the work breakdown structure (WBS).
  • Determining the relationship between activities.
  • Develop the project network.

 

(1)Identifying all activities needed to build the project

In-depth understanding of the project scope leads to a clear and logical identification of activities.

Types of activities in construction projects:

  • Production activities: activities that involve the use of resources such as labor, equipment, material, or subcontractor. Examples are excavation, formwork
  • Procurement activities: activities that specify the time for procuring materials or equipment that are needed for production activity. Examples are brick procurement.
  • Management activities: activities that are related to management decisions such as approvals, vacations, etc.

(2)Creating the Work Breakdown Structure

The work breakdown structure (WBS) is an organized collection of the project deliverable components to be created by project work.

  • The project manager can’t complete this activity
  • The input and guidance of the project team is required as they are the individuals closest to the work and will be completing the actual activities within the project phases
  • The WBS offers major input into planning, estimating, and scheduling processes throughout the project.

As shown in the figure:

level 1 represents the full scope of work for the house.

In level 2, the project is sub-divided into its three main trades

in level 3 each trade is sub-divided to specific work packages

(3)Determining the relationship between activities

(a) Finish-to-Start relationships

“finish to start“ relationship requires that an activity can start only after its predecessor has been completed.

For example, it is possible to lift a piece of equipment by a crane only after the equipment is secured to the hoist.

“Activity A must be completed before Activity B can begin”

Activity

A

Activity

B

 

(b)Start -to-Start relationships

“start to start” relationship exists when an activity can start only after a specified activity has already begun.

For example, you can begin hanging wall papers as soon as the painter applies glue on the wall.

“Activity B starts as soon as activity A starts”

ACTIVITY

A

ACTIVITY

B

 

(C)Start -to-Finish relationships

The “start to finish” relationship occurs when an activity cannot end until the predecessor activity begins.

Handing over the building to the client cannot be done until addressing the snag list issues begins.

“Activity B completes when activity A starts”

ACTIVITY

A

ACTIVITY

B

 

(d)Finish -to-Finish relationships

The “finish to finish” relationship is used when an activity cannot terminate unless another activity is completed.

Contractors cannot get paid before the engineer checks the work and approves the payment.

“Activity B cannot finish until activity A finishes”

ACTIVITY

A

ACTIVITY

B

 

(e)Parallel Relationship

The other type of relationship occurs when two activities can be done at the same time

Another form is called the parallel relationship model

Activity C and Activity D begins at the same time and end at the same time and both activities must be completed before Activity E can begin due to the dependence of E on C and D or for other reasons

ACTIVITY

C

ACTIVITY

E

ACTIVITY

D

(4)Develop the project network

There are two main methods that are mainly used to draw a network diagram for a specific project:
