Project Scheduling in Quantity Surveying

Project scheduling is the foundation of effective project management, offering a road map for completing tasks on schedule and meeting project objectives. Effective scheduling is crucial for maximising resources, reducing delays, and completing projects on time and within budget in the fast-paced world of construction and development, where time is money. The significance of project scheduling, its function in project execution, and the critical role quantity surveyors play in managing it are all covered in this article.

What is Project Scheduling?

Project scheduling entails creating a precedence and resource feasible time schedule that outlines the individual anticipated start and finish periods of the activities. There is little doubt that the most widely used time-based objective function is to minimise the project makespan. Both renewable and non-renewable resource types are supported by the suggested formulation. The former are replenished on a regular basis, although their amount is restricted and may vary from one period to the next. The latter’s availability restrictions, however, are limited to the project’s overall use.

Significance of Project Scheduling in Quantity Surveying

Proper project scheduling may benefit everyone, including you, your organisation, employees, contractors, and clients. When you consider the future of a project, consider these typical advantages of project planning and scheduling.

You can get a better quote for your project

A successful bid is the first stage in any building project. To impress a potential client, however, it is not enough to bid the proper amount and provide the right words and supporting paperwork. Should your estimate be inaccurate, you can be the one responsible for paying the expenses if a project goes awry.

You can make sure that everything is taken into consideration by taking the time to review a thorough and practical building timetable before making a decision. And that implies you’re more equipped to respond honestly when asked how much a task would cost to complete or if you can finish it in a given amount of time.

Schedules help you manage resources more effectively

Resource management has a significant role in the building timetable. If you have four construction tasks going on at the same time, you might only have access to one plumber, so careful and effective scheduling is crucial. If not, you risk having several of your tasks put on hold while you wait for the plumber to finish up at another job and become available.

It is necessary to schedule specialists like electricians and plumbers. However, equipment, supply of materials, inspections, and general labour also do so. Furthermore, since resources are limited, it is essential to have a precise building timetable to guarantee that all of these resources may be allocated in the most effective manner.

Cost estimates are more precise

Precise bids and quotes also benefit your company. A strong construction schedule provides you with a firm framework around which to build your cost estimates and prices. This is partly because you can bargain for favourable bulk prices on common supplies by using your knowledge of other projects and the dates you’ll need certain products to complete them.

You can schedule time to prepare for known or future problems

If a client requires something completed within 8 months and you need exactly 240 days to achieve it, that is poor scheduling since you are not leaving any room for barriers or complications to develop. For a few weeks, there is no guarantee that a permit will not be delayed or that a tropical storm won’t impede work.

Starting with a construction timetable, you can estimate some known concerns and account for them in the plan by considering the time of year and the job’s location. By factoring in additional time, you can also account for unforeseen problems and virtually ensure that your worst-case scenario will conclude on schedule.

You can effectively manage safety concerns

Making plans in advance allows you to know when potentially dangerous tasks, like demolition, may need to be done. It is possible to proactively guarantee that all required safety resources will be available while also clearing out superfluous and extraneous resources from the site to make them unobtrusive. This lowers the possibility that someone could get hurt.

The Best Way to Draft Project Scheduling

Define Project Scope:  Establish the project’s scope in detail, taking into account its deliverables, goals, and limitations. Having a firm grasp of the scope is essential to creating a precise and practical project schedule.

Sequence Activities: Determine the order in which tasks should be completed, taking into account dependencies and limitations. To determine the most effective order of tasks, apply strategies like critical path analysis and the precedence diagram method.

Break Down Tasks: Divide the project into smaller, more doable work packages, each with its own requirements and dependencies. This breakdown aids in figuring out the tasks’ order, length, and resource requirements.

Estimate Durations: Use historical data, expert judgement, or industry benchmarks to estimate the time required for each task. When making estimations, be reasonable and take the availability of resources, the state of the weather, and potential hazards into consideration.

Distribute Resources: Figure out how much labour, supplies, machinery, and subcontractors are needed for each task. In order to ensure that resources are acquired and distributed effectively, quantity surveyors are essential in this step since they can precisely estimate material quantities and costs.

Create a Schedule: Using scheduling tools like Gantt charts or project management software, create a detailed project schedule that includes important deadlines and milestones, as well as the start and end dates of each activity.

Review and Adjust: Once the schedule has been created, thoroughly review it to ensure accuracy and viability. Adapt as necessary to take into consideration shifts in the scope, the availability of resources, or other elements that could affect the timeline.

The Role of Quantity Surveyors in Project Scheduling

Particularly in the areas of resource assessment and cost management, quantity surveyors are essential to the administration of project scheduling. Their proficiency in quantity takeoff, cost estimating, and procurement guarantees that the project schedule is developed using precise and trustworthy data. In close collaboration with project managers and other stakeholders, quantity surveyors:

Cost Estimation

Quantity surveyors assist project managers in creating a realistic budget and efficiently allocating resources by providing cost estimates for supplies, labour, equipment, and other project expenses. Their proficiency in managing expenses guarantees that the project adheres to financial limitations and provides value for the money.

Calculate Material Quantities

Using project specifications and design documents as a basis, quantity surveyors precisely calculate the amounts of materials needed for every task or activity. Determining resource requirements and timely material procurement depend on this knowledge.

Value Engineering

By locating areas for cost reduction and alternative building materials or techniques that can assist optimise project costs without sacrificing quality or performance, quantity surveyors support value engineering initiatives. They achieve improved cost efficiency and optimise the project’s return on investment with their proactive approach to cost management.

Procurement Planning

Quantity surveyors are responsible for selecting acceptable suppliers and subcontractors, collecting quotations or bids, and negotiating contract terms. Quantity surveyors minimise delays and disruptions by aligning procurement processes with the project schedule, which guarantees the availability of goods and resources as needed.

Conclusion:

Project scheduling is a vital component of project management because it allows for successful planning, execution, and control of project operations. Organising a project’s schedule helps to maximise resources, reduce risks, and guarantee that deliverables are completed on time. In order to ensure that construction projects are completed successfully, quantity surveyors use their knowledge of cost control and resource estimation to oversee project scheduling. Quantity surveyors assist in making sure that projects are completed on schedule, within budget, and to the highest levels of quality and excellence by working closely with project managers and stakeholders.
