The Principal Function of the Quantity Surveyor in Any Construction Project
The quantity surveyor is in charge of estimating the cost of a construction project. They also play other functions, including as ensuring that production and cost management are carried out as effectively as feasible.
The reason why quantity surveyors are given this title is because they create a "schedule of quantities" - an estimate of the material and labour costs — against which contractors' tenders may be evaluated. (Contractors are not chosen just based on price, though.) The schedule is also known as a cost projection.
Quantity surveying professionals may also go by the titles of estimator, cost engineer, cost manager, cost analyst, project coordinator, project cost controller, and cost planner.
The primary responsibilities of a quantity surveyor are:
• handling the finances for any form of building project, be it a home, a high-rise, a bridge, or a tunnel
• attempting to complete the project on schedule
• striving to keep the project inside the budget
• Ensuring that manufacturing and construction expenses are managed as effectively as feasible
• settling arguments between parties to a contract.
• creating insurance replacement estimates for various types of structures, including homes.

Prior to the project, the quantity surveyors determine a budget depending on the needs of their clients. To guarantee that the budget is adequate for each step of building, they create thorough estimations.
Their main responsibility is to ascertain the total cost of a building project, including labour, materials, and services.
Quantity surveyors can assist with feasibility assessments for a project before construction even begins. Based on measurements of the designer's or client's sketches, they can roughly estimate the scope of the project.
The quantity surveyor examines the architectural and engineering drawings, asses the associated expenses, and then establishes an all-inclusive estimated budget for the project. They might make comparisons between the project and similar ones.
The quantity surveyor can then use workable ideas to plan costs to assist the design team in staying within the project budget. Value engineering is the term for this.
The quantity surveyor and a project architect collaborate to create the final, thorough estimate. This serves as the framework for evaluating tenders.
When building begins, the quantity surveyor controls expenses.
Once construction has begun, the quantity surveyor can give cash flow information so the customer can make the necessary financial arrangements for each stage of the project.
Additionally, the quantity surveyor can negotiate a "variant" with contractors and determine the economic implications of project adjustments like delays.
The quantity surveyor can assist a client by preparing draw down certificates for money that the bank will loan and can offer a bank with a project report for the project.
Another duty in some projects is to settle arguments between clients, designers, and construction companies.
The quantity surveyor totals the cost after construction is complete.
A statement of final account, which lists the real costs for each job component, can be created by the quantity surveyor.
What do estimating and costing mean?
Calculating or evaluating a quantity using estimation, i.e., without using precise measurements, is known as estimation. In civil engineering and other engineering fields, estimating is a crucial procedure.
This is typically carried out in the planning stages before a purchase or building starts. Estimating is typically more precise, but there are some drawbacks. For example, if your estimate depends on labour costs, you'll need to know how many man-hours it will take to finish the job.
Estimates are created using observations and historical experience. The quantity of detail at hand and the length of time that data are accessible for analysis both have an impact on how accurate an estimate is.
Costing is the process of calculating a project's estimated cost before it is started. It can be done with an itemised list or by estimating utilising a construction cost calculator.
Estimating, bidding, and finalising are the three phases that make up costing. It aids in the estimation of the project's funding needs.
A "costing" often refers to how much it will cost someone to manufacture one unit of something, in this case most likely building activity.
There are two categories of costings: -
Independent costing is the cost of the direct labour and material costs. This sort of pricing is not indicative of the total cost of the project because it only accounts for the cost of a particular phase.
Cumulative costing examines the overall cost of all work phases, although it can be challenging to guarantee that estimates are accurate.
Within the construction industry, quantity surveyors and estimators have certain roles to play.
A quantity surveyor may work for the customer, the contractor, or a subcontractor, and their place of employment may be an office or the actual construction site. They get involved in a project right away, assisting with the creation of work budgets and cost estimations.
While the project is still being worked on, quantity surveyors are in charge of keeping an eye on any contract changes that can have an influence on costs and producing reports that show the project is profitable.
He or she will perform the duties of a project engineer in addition to those of a quantity surveyor. In this capacity, he or she will be in charge of overseeing the project, following construction protocols, organising all work schedules with the principal contractor, and corresponding with the project manager and the architectural coordinator.
He or she is in charge of overseeing and ensuring that the work is progressing within the confines of the project schedules in addition to autonomously managing the project and motivating and leading the team.
Quantity estimation and the development of BOQ and BBS papers in accordance with designs
• Coordinating with the Design and Construction team.
• Examine the engineering plans and specifications, confirm that the specifics of the drawings have been accurately translated to the ground, and confirm that all centering and reinforcing works have been finished.
• The actual measuring of quantities as well as the observation of productivity levels.
• Ensuring that the resources are available in a timely manner.
• Conducting a cost analysis for adjustments and repairs that the customer conducted that fell inside the project's purview.
• Making financial arrangements and conducting a review of the completed work.
• Ensure that the structure is of a high calibre, that the work is completed in accordance with the plans and the specifications, and that no rework is required.
• Analyzing data in-depth and creating thorough status reports
• Creating daily, weekly, and monthly reports and submitting them to management
A QS may perform a number of jobs within the construction business. Below are a few that are related to the construction site.
estimation of material quantities A QS will measure the drawings and determine how much cement, sand, aggregate, steel, brick, block, tile, paint, etc. to be purchased.
Contracts for Procurement - The QS of a Client will publish Tenders/RFQs, hold negotiations, finalise contracts, publish work orders/agreements, and so forth. The Quantity Surveyor (QS) for the Contractor will estimate the quantities and conduct a rate analysis prior to submitting a tender.
Monthly bill checking comprises the Quality Assurance representative of the client analysing the monthly invoices submitted by the contractor and the Quality Assurance representative of the contractor generating the monthly invoices based on the work that was accomplished on the job site.
Material reconciliation calls for the QS to create a Reconciliation statement based on the number of materials received, the quantity of materials used, the balance on site, and the amount of material that was wasted.
Reports will be created, including monthly Cost reports, Progress reports, Cashflow information, and other sorts of reports as required by the QS.
What do estimating and costing mean?
1. Cost estimation is used to forecast the quantity, cost, and price of the resources needed to complete a project. Any procedure that is launched to carry out work tasks or produce assets may be considered a project. The degree of project scope definition has a significant impact on the estimation's accuracy; as the project's conditions and design are better defined, so are the estimated values. Consider the five AACE estimate classes that were mentioned previously.
2. Cost estimating is necessary to give decision-makers the tools they need to pick between options, make investment decisions, and establish the budget at the beginning of projects. For this, clients' estimates must also be verified by those provided by vendors and contractors. The budget estimate is used as a starting point to evaluate the project's performance in following phases.
In keeping with this idea, gathering and interpreting the vast amounts of cost data is usually difficult and isn't helpful for making decisions. Making the cost data usable and meaningful begins with analysis and visualisation. A project control software system's dashboards are the data-driven graphical representations of a project. Dashboards can give decision-makers a quick overview of a project's status and transform data into decision points.
3. To estimate, divide the project's overall scope into smaller, more manageable components that may each be given a cost and resource allocation. There are standardised methods for breaking down a project, such as the Work Breakdown Structure (WBS) and the Cost Breakdown Structure (CBS), but depending on the needs of the project team and outside parties, multiple structures are frequently implemented to align reporting and sharing of cost data.
4. A cost estimate is more than just a list of expenses. It also provides a thorough Basis of Estimate (BOE) report that outlines the assumptions, inclusions, exclusions, accuracy, and other factors required to evaluate the overall project cost. Otherwise, it would be a meaningless number. The BOE must be shared with the various decision-making stakeholders and is useful at closeout when comparing the project's performance to that of other projects. It is the crucial element—frequently overlooked—that enables you to draw lessons from your past experiences and blunders.
Cost estimation, however, is much easier said than done. A successful strategy can be distinguished from a failed one by an accurate estimation technique. You already have a framework to start estimating if you keep these 4 ideas in mind. To ensure a smooth transition into project cost estimating software, which will eventually enable you to produce more reliable and accurate estimates, be sure to build up the estimate in an organised approach.
