What Does a Construction project schedule mean?
A construction schedule serves as a chronological plan for a building project, enabling construction managers to determine the sequence and duration of construction activities. It also tracks milestones, deliverables, and interdependencies to ensure that projects remain on schedule and within budget.
Varieties of construction project schedule
Construction managers have a range of options when it comes to selecting the type of construction project schedule to employ. In fact, multiple scheduling methods can be used for a single construction project. By understanding the distinctions between these techniques, you can choose the most suitable approach for your project’s requirements and team.
Let’s explore the following methods for developing an effective construction project schedule and consider which approach best aligns with your project or team:
– Critical Path Method (CPM): This method estimates the overall completion time of a construction project by identifying all tasks that are dependent on one another within the timeline. These dependent tasks are those that cannot begin until a previous task is completed. By utilizing the critical path method, managers can anticipate changes in the completion date if there are delays or acceleration in critical path activities.
– Program Evaluation and Review Technique (PERT): PERT estimates the completion date of a construction project by considering optimistic, pessimistic, and most likely schedule forecasts. Managers begin by creating a diagram of the building project and then use the PERT formula, which assigns greater weight to the most likely time estimate compared to the other two. This method acknowledges the potential for project variation and is particularly useful for unique or innovative construction projects as it is more sensitive to risks.
– Gantt Chart: A Gantt chart is a simple spreadsheet that lists each task required to complete a project and tracks their progress over time. This document allows for updating future activities and completion dates based on actual progress. Construction managers appreciate Gantt charts as they provide a quick, high-level assessment of overall progress and facilitate the identification of problems and delays.
– Line of Balance (LOB): LOB charts track actual progress against expected progress. This method is ideal for construction projects involving repeated units of work, such as tall multi-floor buildings that require the same tasks for each floor. By employing this method, managers can calculate the time required for each repetition and predict the remaining time needed to complete the remaining units. Additionally, this technique helps managers adjust schedule forecasts as the team becomes more efficient in completing repeated tasks. However, it has limited value in projecting the overall duration of the critical path, as it only considers the repeated tasks.
– Quantitative Scheduling: This method schedules the utilization of materials and equipment across different project locations in the most efficient manner. Also known as Q scheduling or queue scheduling, this technique focuses on the order of activities and resource allocation’s impact on the budget. It is a visual method that displays the quantity and duration of resources required at various project locations and times.
– Resource Scheduling: This approach prioritizes the efficient allocation of resources while considering time, labor, funding, space constraints, and other crucial project details. There are two primary ways to handle resource constraints: Resource leveling, which allocates resources at a consistent level and adjusts the project schedule accordingly, and resource smoothing, which prioritizes time constraints by modifying project activities to ensure resource demand does not exceed capacity or by adding more resources.
– Last Planner System: This holistic Lean approach considers all the intricate aspects of a construction project. The Last Planner System divides projects into five planning stages. Master planning involves creating a construction schedule for the entire project. Phase planning entails developing detailed schedules for each project phase, and weekly work planning involves creating reliable schedules for each week. Make-ready and learning phases help managers anticipate constraints and reflect on areas of improvement as the project progresses.
– Lookahead Planning: Lookahead planning involves preparing a project schedule that covers a short upcoming period, typically six weeks or fewer. As part of the make-ready phase of the Last Planner System, construction managers utilize a lookahead schedule to prepare for future work. This process is often integrated into the weekly work plan.
– Master Schedule: A master schedule compiles all high-level scheduling details for a construction project into one comprehensive and easy-to-read document. It specifies major deliverables, individual work breakdown structure elements, and project milestones. Also referred to as a level one, management, integrated master, or major milestone schedule, the master schedule is typically one page and includes a Gantt chart, incorporating information from all aspects of the project.
– Milestone Chart: A milestone chart presents the key events, deliverables, and important dates of a construction project in a concise format. Unlike tasks or activities, milestones highlight significant project milestones, such as permit approval, contract award, and final walkthrough.
The importance of a construction project schedule
The life cycle of a construction project commences when an owner recognizes a market demand and concludes when the project is finalized and handed over to the owner. An effectively implemented construction project schedule delineates each phase and establishes target dates for completion.
Ensuring timely and cost-effective construction projects
Construction schedules serve as the foundation for various financial outcomes. Formulating initial schedules can be advantageous for predicting completion and key milestones that can impact financial decisions.
Baseline schedules play a pivotal role in keeping construction projects on track in terms of time and budget. It is never too early to devise a plan and understand the project timeline. Grasping the fundamentals of scheduling is an essential aspect of constructing and managing projects.
Planning the construction project schedule
Several factors should be taken into account when planning a construction project schedule, including design considerations, required permits, and costs. The scheduling process compels contractors to visualize how they will execute the project, facilitating meticulous planning and the creation of a clear plan that can be shared with all stakeholders.
Construction schedules primarily concentrate on two key aspects: estimating the duration required for each activity and determining the responsible parties for executing each activity.
Advantages of a well-developed construction schedule
A well-executed construction schedule aids in the management of resources such as materials, labor, and equipment. It also allows for adjustments to accommodate unforeseen events, enabling construction management to successfully complete projects within the designated time and budget.
Construction schedules assist in identifying and overseeing the activities necessary to accomplish each task, as well as establishing the sequential order in which tasks should be executed.
