Crash Task on critical path We are confronted with having to reduce the scheduled complete time of a project to meet a deadline. The project duration can be reduced by applying more resources like more labor‚ additional equipment‚ and working overtime hours to complete the project. After observing the MSP timeline‚ we selected the most critical tasks for the project: Framing 14-16 Floors Steel Framing Concrete Flooring 7-16 Rough-Ins Utilities Finishes Furnishings Closing In considering

finished. Estimation can be defined as the process of scheduling tasks and the budgeting of resources for those tasks. The two most important components of these steps or stages are scheduling and budgeting. However‚ the difficult aspects of project management remain those centred on estimating task duration‚ including the execution and monitoring of tasks (Burns and Janamanchi‚ 2007). Project scheduling is using known project tasks (activities) and putting them into a timeline while project budgeting

According to the network diagram above The critical path of the project is: Activity 1 Activity 2 Activity 5 Activity 7 Activity 10 Activity 13 Activity 15 As audit of liquid assets (activity 4) is not on the critical path‚ it is not a critical activity. This slack job has a slack time of 178 hours for which slack time= late start time – early start time (231-53) = late finish time – early finish time (266-88). The project duration will not be affected even if David takes his one

Critical Path Procedure 1. Develop a list of the activities that make up the project. 2. Determine the immediate predecessor(s) for each activity in the project. 3. Estimate the completion time for each activity. For example: Activity Immediate Predecessor Time A - 3 B - 1 C - 2 D A‚ B‚ C 4 E C‚ D 5 F A 3 G D‚ F 6 H

Critical Path Analysis (CPA) Critical Path Analysis: A project-management technique that lays out all the activities needed to complete a task‚ the time it will take to complete each activity and the relationships between the activities. Sets out all the individual activities that make up a larger project. Shows the order in which activities have to be undertaken. Shows which activities can only take place once other activities have been completed. Shows which activities can be undertaken

The total duration of the construction project by adding the estimated task duration serially would give us 70 weeks. But some tasks within some activities can be done in parallel sequence or simultaneously‚ which would significantly reduce the construction project completion time using the critical path method (CPM). In this method the longest path is the critical path which runs through one of the route in the project network diagram from start to finish. This project network diagram is illustrated

CRITICAL PATH ANALYSIS To be completed successfully‚ a project needs to be planned and managed‚ costs determined and times allocated‚ problems dealt with and‚ eventually‚ concluded. Formal methods of managing a project offer clear guidelines and deadlines. The key elements of project management include: • defining the project carefully‚ including the setting of clear objectives • dividing the project up into manageable tasks and activities • controlling the project at every stage to check
