The critical path methods (CPM) have been used for planning and scheduling in construction projects. The use of CPM varies from user to user, with some contractors feeling that CPM is a waste of time and money. With the time, the use of project management technique have improved with experience. Most likely, the unsuccessful applications(…)
Construction Scheduling
CONCRETE CONSTRUCTION STAGES
During the concrete construction stage, actual work is executed as per the plans and specifications prepared earlier. The construction methodology is carried out in a planned manner preventing wastage of manpower, materials and money and ensuring completion of the project within the stipulated time, cost and quality. The various activities of this stage can be(…)

The Objectives of the projects in definite words Goals and stages(…)
RELEVANCE OF CONSTRUCTION SCHEDULES
In addition to assigning dates to project activities, project scheduling is intended to match the resources of equipment, materials and labor with project work tasks over time. Good scheduling can eliminate problems due to production bottlenecks, facilitate the timely procurement of necessary materials, and otherwise insure the completion of a project as soon as possible.(…)
ESTIMATING PROJECT ACTIVITY DURATION
All formal scheduling procedures rely upon estimates of the durations of the various project activities as well as the definitions of the predecessor relationships among tasks. The variability of an activity’s duration may also be considered. Formally, the probability distribution of an activity’s duration as well as the expected or most likely duration may be used in scheduling. A probability distribution indicates the chance that a particular activity duration will occur. In advance of actually doing a particular task, we cannot be certain exactly how long the task will require.
