INTRODUCTION

  • The decision-making process faces a number of technological hurdles even as it considers the significance of technical efficiency from an executor and professional point of view.
  • In order to improve the project management process, the Gantt chart is still utilized in project planning.
  • The critical path method, also known as CPM, is commonly used in industrialized countries.
  • The planning, managing, organizing, and controlling operations make up the bulk of the execution phase of construction

AIM OF THE PROJECT

  • To plan the activities for the construction project's execution phase and to talk about its key components and works.
  • All the key components are considered in the critical path
  • Key components or tasks are to be considered with higher importance

Methodology

  • A project Gantt chart needs to be made when the professional quantity survey has been decoded and the activities have been modeled using relationships.
  • The different activities/tasks are scheduled using a work break down structure
  • Duration is allocated for each and every tasks and sub tasks
  • Dependencies are given for each tasks and sub tasks
  • The critical activities are determined from the critical path
  • The critical activities are to be considered with importance
  • Critical path method (CPM) identifies essential path for activities in all stages.
  • In CPM method the scheduling of project involves splitting up of a task into multiple job task

This is displayed in a flow chart by calculating duration for each task

  • the overall project duration is determined based on the individual functions
  • The critical path method (CPM) is a popular scheduling technique in the construction industry due to its simplicity and effectiveness.
  • It generates a graphical view of a project and calculates how much time and resources are required to complete each It also determines critical activities requiring attention so that the project can be completed on time.
  • Without proper scheduling, no construction project would be completed on time. The foundation of that project schedule should typically be made up of the essential tasks to keep the project moving. That brings us to the Critical Path Method, which is widely used in the construction industry.
  • Utilizing the Critical Path Method might be a little intimidating at first blush, but it’s simple at its core – plus utilizing it’s a great way to make projects more efficient.

  • The project stakeholders are to be informed all the important details of the project
  • Critical activities are to be considered with importance
  • CPM is constructing a model of the Therefore, project managers and superintendents need to have a few essential information points for CPM for project management.

Details of the project

  • Project name – Construction of complex structure
  • Project objective(s) - The project involves construction of structural and architectural elements associated with the project
  • Project duration – total 8 months
  • Starts date – November - 2022
  • Project manager name – Kim Joode
  • Project team - The project team includes construction planners, project managers, construction managers, supervisors, and workers.

Starting the project

  • List of The first step is defining the list of activities
  • Project mangers prepare a work break down structure to list all the activities when required to be completed
  • The preparation of WBS helps in breaking down of a project into smaller size
  • Smaller components are correctly organized based on hierarchy as per the level of importance and critical

CRITICAL PATH IN THE PROJECT –

CRITICAL PATH IN THE PROJECT

CONCLUSION

  • The study highlights the significance of delays and their effects on entire projects.
  • The use of the management principle in exceptions is made possible by the task and resource activities, which also identify the crucial path.
  • Now that project managers may use Gantt charts and CPM approaches to concentrate on the project's most important tasks, the project can be completed.
  • Using graphical networks, interdepartmental communication, and explicit accountability for assigning key tasks to the right people and managing crises in a way that minimises their effects on projects, many ways of finishing the project can be
