I. Introduction

• Planning−The process of preparing for the commitment of resources in the most

effective fashion.−Planning can be thought of as determining “what” is going to be done,

“how,” “where,” and by “whom.”− In Scheduling, this information is needed in order to determine “when.” 4

I. Introduction

• Estimating−To form an approximate judgement regarding the worth, amount, size,

etc. 5− “To determine the probable cost of the project, construction estimates

are prepared before a project is constructed. Thus, an estimate is, at best, a close approximation of the actual cost.” 6

I. Introduction

• Estimating− “The soundness of the completed estimate depends on the following

two factors: (1) the accuracy of the quantity take-off and (2) the judicious selection of the unit costs and production rates to be used.” 7

I. IntroductionThe Schedule

July 19, 2016 13

• What is the purpose of a Construction Schedule?− “When used properly, the project schedule is effective in project

management, analysis, control, and overall performance, not just as a device for telling subcontractors where to move their workforces.”

− “Network-Based project management methodology (Schedule) is a dynamic planning and control procedure.”

I. IntroductionHistorical Development of Construction Schedules

07-APR-16 27

• Early forms of scheduling date back over 3000 years to the construction of Egyptian pyramids.

• 1765: Joseph Priestley first developed the bar chart to plot the lifetimes of various famous people.

• 1759-1823: William Playfair is the first to develop a range of statistical charts including line, bar, and pie charts.

• 1896: Polish researcher Karol Adamiecki developed the Harmonygraph (Harmonogram).

• Network-Based Schedules (CPM)−Consists of 2 main components

1. Network – a graphical portrayal of the plan for carrying out the work (schedule) showing the dependency relationship among the project activities.

2. Arithmetic Procedure (Scheduling Computations) – an algorithm is applied, based on network logic, to determine how long the project is expected to take and when each activity may be scheduled.

• Arithmetic Procedure− Forward Pass Beginning at a specified project start time, proceed sequentially from the

beginning to the end of the project giving the earliest (expected) start and finish times for each activity.

−Backward Pass Beginning at the end of the project, proceed sequentially from the end to the

beginning of the project giving the latest allowable start and finish times for each activity. 8

• Delay in the Context of the Construction Industry− In construction claims, the term “delay” is used to mean two different

but related matters. Delay is often used to mean the time period during which some part of the construction project has been extended beyond what was originally planned due to unanticipated circumstances.

−Delay can also be the incident that affects the performance of a particular activity, with or without affecting project completion.

• Constructive Acceleration Hurdles1. There must be an excusable delay.2. There must have been timely notice of the delay and a proper request

for a time extension.3. The time extension request must either be postponed or refused.4. The owner or other party must by coercion, direction, or in some other

manner that reasonably can be construed as a command order completion within the unextended performance period.

5. The contractor must actually accelerate its performance and thereby incur added costs. 16
