The importance of having a schedule for a construction project

The importance of having a schedule for a construction project

Construction projects are delicate operations that need to run on time in order to stay within the allocated budget. As soon as a project is delayed, it costs the contractors and building owners more money. Having a strict schedule is important as it keeps the project on time and allows all workers to know when to expect certain deliveries and deadlines.

A schedule is the process of assigning tasks, activities, milestones and deliveries to a construction project – basically setting deadlines that everyone will work towards meeting. The schedule will be used by all construction teams on the project, as well as the suppliers, to finish the building on time. It outlines the pace of work and how the tasks are supposed to be executed, but it also outlines how the team should deal with changes in the plan and delays. 

Why a construction schedule is important

The schedule is a vital planning document that outlines the following points:

  • It assigns dates and deadlines for the project’s activities.
  • Contractors can see whether these deadlines are obtainable or not and whether delays can be avoided.
  • The schedule allows contractors to estimate preliminary costs or tender bid estimates.
  • It can be used to plan the necessary resources (such as equipment, materials and labour) to meet the work tasks and deadlines.
  • The schedule provides a sequence of tasks so the project manager and all teams know what they need to be working on and what tasks they need to be prepared for.
  • It can improve the safety performance of a project by sequencing activities to ensure maximum protection for contractors.
  • It enables teams to set their own goals and work towards achieving these.
  • It outlines how delays can be dealt with in the smoothest and most efficient manner.
  • It eliminates problems of production bottlenecks, where many deadlines fall on the same day.
  • The schedule ensures that the project is completed at the soonest possible date.
  • It gives the building owners a target date by which their building should be ready for use.
  • It can be used post-completion to evaluate the contractors’ performances and to assign responsibility for any delays or overspending.

The building schedule is one of the most important documents for project managers, contractors and building owners. It keeps a project running on time and within budget. However, the schedule needs to be realistic and the estimations need to be achievable in order for it to be a valuable resource for the project.
