Introduction
The construction industry relies on numerous professionals to ensure projects are completed efficiently, on budget, and to high standards. Among these specialists, quantity surveyors play a pivotal yet often misunderstood role. These professionals serve as the financial backbone of construction projects, helping to manage costs from concept to completion while ensuring value for all stakeholders involved.
Whether you're considering a career in quantity surveying, looking to hire a quantity surveyor for your next construction project, or simply curious about what these professionals do, this comprehensive guide covers everything you need to know. We'll explore their diverse responsibilities, various specializations, earning potential, fee structures, professional appearance, and accuracy in cost projections.
What Do Quantity Surveyors Do?
Quantity surveyors (QS) are financial and construction experts who specialize in managing and controlling costs throughout the entire construction project lifecycle. Their role extends far beyond simple cost calculations, encompassing a wide range of financial and contractual responsibilities.
Core Responsibilities
Quantity surveyors provide crucial financial oversight and technical expertise across several key areas:
Cost Estimation and Budgeting
At the project's outset, quantity surveyors develop detailed cost estimates based on architectural plans and specifications. These estimates form the foundation of project budgets and financial planning. Using specialized knowledge of construction materials, methods, and market rates, they create comprehensive breakdowns of project costs from groundbreaking to completion.
Procurement and Tender Management
Quantity surveyors prepare tender documents, including bills of quantities that detail all materials, labor, and equipment required for a project. They evaluate contractor bids, negotiate terms, and help select the most suitable contractors. This process ensures that clients receive competitive pricing while maintaining quality standards.
Contract Administration
Once construction begins, quantity surveyors administer contracts between clients and contractors, ensuring all parties fulfill their obligations. They review and process payment applications, assess the value of completed work, and advise on contractual matters. Their expertise helps prevent disputes and ensures fair treatment for all involved parties.
Cost Control and Value Engineering
Throughout construction, quantity surveyors monitor expenditures against budgets, flagging potential overruns early. They implement cost control measures and suggest value engineering opportunities—ways to maintain or improve functionality while reducing costs. Their proactive approach helps prevent budget creep and maximizes the client's return on investment.
Variation and Change Order Management
Construction projects rarely proceed exactly as planned. When changes occur, quantity surveyors assess their financial impact, negotiate fair prices for additional work, and ensure proper documentation. This careful management prevents disputes and maintains budget transparency.
Claims and Dispute Resolution
When disagreements arise over costs, delays, or contractual interpretations, quantity surveyors provide expert analysis and documentation to support resolution efforts. They may assist with mediation or serve as expert witnesses in construction disputes, offering independent assessment of financial matters.
The Evolving Role
The quantity surveying profession continues to evolve with changing industry demands. Many modern quantity surveyors now offer expanded services including:
Life cycle costing analysis to assess long-term operational costs
Sustainability consulting to optimize environmentally friendly design choices
Building Information Modeling (BIM) integration for improved cost accuracy

What Do Quantity Surveyors Charge?
When engaging a quantity surveyor for your construction project, understanding their fee structures helps you budget appropriately for their services.
Fee Structures
Quantity surveyors typically use one of several fee models:
Percentage-Based Fees
Many quantity surveying firms charge a percentage of the total construction cost. This percentage typically ranges from:
1-3% for large projects (over AU$5 million)
2-5% for medium-sized projects (AU$1-5 million)
3-7% for smaller projects (under AU$1 million)
The percentage often decreases as project value increases, reflecting economies of scale in service delivery.
Fixed Fees
For clearly defined scopes of work, quantity surveyors may offer fixed fees. This approach provides budget certainty for clients but requires thorough upfront definition of services. Fixed fees are common for specific deliverables like feasibility studies, bill of quantities preparation, or bank report services.
Hourly or Daily Rates
Some services, particularly those with unpredictable scopes like dispute resolution or forensic analysis, may be charged at hourly or daily rates. Typical rates in Australia range from:
AU$150-250 per hour for junior to mid-level quantity surveyors
AU$250-400+ per hour for senior quantity surveyors or specialists
AU$1,500-3,000+ per day for expert witness or consulting services
Retainer Arrangements
For ongoing projects or clients with regular construction activities, quantity surveyors might offer retainer arrangements with a set monthly fee covering a specified level of service.
Factors Affecting Fees
Several factors influence how much quantity surveyors charge:
Project Complexity
Technically complex projects require more specialized knowledge and detailed analysis, justifying higher fees. Similarly, projects with numerous variations or complicated contract arrangements demand more intensive management.
Service Scope
Comprehensive services from pre-construction through post-completion will naturally cost more than engagement for a single project phase. Clients can often select service packages tailored to their specific needs and budget constraints.
Market Conditions
During construction booms, quantity surveying services may command premium rates due to high demand. Conversely, during downturns, firms might reduce fees to remain competitive.

As Bidkon notes on their website: "Our fees are based on the complexity and scale of each project. We offer transparent pricing and can provide a detailed quote after assessing your specific requirements. We strive to deliver exceptional value for our services, helping clients optimize their project budgets."
What Do Quantity Surveyors Wear?
While seemingly trivial, professional appearance plays an important role in the quantity surveying profession. Quantity surveyors must project competence and credibility while also maintaining practicality for their diverse work environments.
Office Attire
When working in office settings or attending client meetings, quantity surveyors typically adhere to business or business-casual dress codes:
Men often wear suits or dress pants with button-down shirts, sometimes with ties for formal meetings
Women typically wear business suits, dresses, or professional separates
Both may adapt to slightly more casual attire (smart business casual) for regular office days
The level of formality often reflects company culture and client expectations. Firms working with corporate or government clients generally maintain more formal dress standards than those serving residential or smaller-scale clients.
Site Attire
Construction site visits require practical and safety-conscious attire:
Personal Protective Equipment (PPE) including hard hat, high-visibility vest, and safety boots
Durable, washable clothing that allows freedom of movement
Weather-appropriate layers, especially for outdoor sites
Long pants (rather than shorts or skirts) for safety and practicality
Many quantity surveyors keep site clothing and PPE in their vehicles to accommodate impromptu site visits. Professional appearance remains important even in these practical environments, as it contributes to credibility with contractors and site personnel.
Evolving Standards
Like many professions, quantity surveying has seen a gradual shift toward more casual attire in recent years. However, the fundamental principle remains consistent: dress should convey professionalism while being appropriate to the specific work environment and client expectations.
How Accurate Are Quantity Surveyors?
Accuracy in cost estimation and quantity takeoff is fundamental to the quantity surveying profession. Clients rely on these projections for critical financial decisions, making accuracy a key measure of professional competence.
Typical Accuracy Ranges
The accuracy of quantity surveyors' estimates typically improves as projects progress through development stages:
Conceptual/Feasibility Stage: ±15-25% accuracy
Schematic Design Stage: ±10-15% accuracy
Design Development Stage: ±5-10% accuracy
Construction Documentation Stage: ±3-5% accuracy
These ranges reflect industry standards rather than guarantees, as numerous variables affect accuracy in any specific project.
Factors Affecting Accuracy
Several factors influence how accurately quantity surveyors can predict costs:
Information Quality
The completeness and clarity of design documentation directly impacts estimation accuracy. Vague specifications or incomplete drawings necessitate assumptions that may prove incorrect. Experienced quantity surveyors identify information gaps early and seek clarification to improve accuracy.
Market Volatility
Construction material prices and labor costs can fluctuate unpredictably due to economic factors, supply chain disruptions, or resource shortages. While quantity surveyors track market trends, sudden changes can affect estimate accuracy, particularly for projects with long planning horizons.
Project Complexity
Unique or highly specialized construction elements present greater challenges for accurate estimation than standard building components. Similarly, renovation projects often reveal unforeseen conditions once construction begins, making them inherently less predictable than new construction.
Timeframe Considerations
Estimates for immediate construction typically achieve higher accuracy than those for projects scheduled years in advance. Long-term projections must account for potential inflation, regulatory changes, and market shifts, increasing uncertainty.
Improving Accuracy
Professional quantity surveyors employ various strategies to maximize accuracy:
Advanced Methodologies
Modern quantity surveying firms utilize sophisticated cost databases, historical project analytics, and specialized software to refine their estimates. Building Information Modeling (BIM) integration has significantly improved quantity takeoff accuracy by extracting precise measurements directly from 3D models.
Continuous Education
Reputable firms like Bidkon invest in ongoing professional development to keep staff current on construction methods, materials, and costing techniques. As noted on their website, they employ "cutting-edge cost estimation and management techniques" to ensure accuracy.

Leading quantity surveying practices implement multiple review layers for estimates, often having senior staff verify calculations and challenge assumptions. This peer review process helps identify potential errors or oversights before presenting estimates to clients.
Contingency Planning
Professional quantity surveyors include appropriate contingencies based on project risk profiles. Rather than arbitrary percentages, these contingencies reflect specific uncertainties identified during the estimation process. This realistic approach helps manage client expectations while providing financial protection against unknowns.
Conclusion
Quantity surveyors serve as indispensable financial guardians throughout the construction process, providing expertise that extends far beyond simple cost calculations. Their specialized knowledge helps optimize project budgets, prevent disputes, and ensure value for all stakeholders.
Whether you're considering hiring a quantity surveyor for your next project or exploring career opportunities in this field, understanding the diverse roles, specialized services, earning potential, fee structures, professional standards, and accuracy expectations provides valuable context for decision-making.
