Chapter Two, Time Planning, explains how construction project scheduling determines the timing, sequence, and overall completion time of activities. It covers why scheduling projects matter, including calculating completion dates, start/end times for activities, predicting cash flow, assessing change-order impacts, improving efficiency, resolving delay claims, and enabling effective project control. The chapter outlines core scheduling steps and the role of WBS to break work into logical, measurable tasks with activity relationships, estimates, and resource, time, and cost assignments.

Scheduling involves: 􀀹 Breakdown of the project into definable, measurable and identifiable tasks/activities(WBS), 􀀹 Establishes the logical interdependence among them. 􀀹 Estimate activity duration 􀀹 Draw graphical presentation(bar/network) 􀀹 Analyze the network Why Schedule projects? 1. To calculate the project completion 2. To calculate the start and end of a specific activity 3. To predict and calculate the cash flow 4. To evaluate the effect of change orders 5. To improve work efficiency 6. To resolve delay claims 7. To serve as an effective project control tool Scheduling involve four main steps: 1. Performing breakdown of work items involved in the project into activities. 2. Activities representation 3. Identifying the proper sequence by which the activities should be executed. 4. Estimating and assigning the resources, time and cost of individual activities. The WBS is described as a hierarchical structure which is designed to logically sub-divide all the work-elements of the project into a graphical presentation. 􀀹 The full scope of work for the project is placed at the top of the diagram, and then sub-divided smaller elements of work at each lower level of the breakdown. 􀀹 The work breakdown structure typically decreases in size from top to bottom: 􀀹 Effective use ofthe WBS will outline the Scope of the project and activities. To the level that estimates and forecasts about the resources required, durations and activity relationships are realistically estimated for each activity; 􀀹 Program: 􀀹 Project level: Projects are derived by dividing a large project, usually termed a program, into independent large-volume mini projects . 􀀹 Task level: A task is an identifiable and deliverable major work which can be performed without major interference from other tasks . 􀀹 Work package level: A work package contains an identifiable, constable and controllable package of work. 􀀹 Activity level: An activity is a sub division of a work package and is defined as a work which has a definite start and end and consumes resources and time and which is measurable.

FAQs

What is project scheduling in construction planning?

Project scheduling determines the timing and sequence of operations and assembles them to obtain the overall completion time.

Why are schedule planning activities important for a project?

Scheduling helps calculate completion, activity start/end times, predict cash flow, evaluate change-order effects, improve efficiency, resolve delay claims, and support project control.

What are the main steps involved in scheduling?

Scheduling involves breaking work into activities, representing activities, identifying the proper execution sequence, and estimating and assigning resources, time, and cost for each activity.
