This article explores the significance of international standards in the realm of quantity surveying, shedding light on its global perspective, and how it impacts the construction industry worldwide.

The Genesis of Quantity Surveying

Before delving into the realm of international standards, it is crucial to understand the essence of quantity surveying and how it has evolved into a globally recognized profession. Quantity surveying emerged in the 18th century in the United Kingdom, primarily as a response to the construction boom during the Industrial Revolution. It began as a profession focused on measuring and quantifying materials and labor required for construction projects. It involves estimating, budgeting, cost planning, and contract administration, ensuring that construction projects are executed efficiently, within budget, and in compliance with legal and technical requirements. 

Over the years, the role of quantity surveyors expanded significantly. Today, quantity surveyors are involved in various aspects of construction projects, including cost estimation, cost control, procurement, risk management, and contract administration. They act as financial advisors to ensure that construction projects are completed within budget while meeting quality and regulatory standards.

The Role of Quantity Surveyors

Quantity surveyors are the financial stewards of construction projects. They are responsible for managing costs, minimizing financial risks, and ensuring that projects are executed within budget constraints.

Their responsibilities encompass several crucial areas:

1. Cost Estimation: Quantity surveyors use their expertise to estimate the costs involved in a construction project. This includes material costs, labor costs, equipment costs, and any other expenses associated with the project.

2. Budgeting: Once the costs are estimated, quantity surveyors help develop a budget for the project. This budget serves as a guideline for the entire project, ensuring that expenditures remain within acceptable limits. 

3. Cost Control: Throughout the project's lifecycle, quantity surveyors monitor and control costs to prevent overspending. They track expenses, make adjustments as necessary, and advise on cost-saving measures.

4. Contract Administration: Quantity surveyors play a vital role in contract management. They ensure that contracts are fair and transparent and that both parties uphold their obligations. This includes managing variations and claims.

5. Risk Management: Identifying and mitigating financial risks is another critical aspect of a quantity surveyor's role. They assess potential risks and work to minimize them to protect the project's financial health.

The Globalization of Quantity Surveying

With globalization came the need for standardized practices in various professions, including quantity surveying. Construction projects are no longer confined to a single country, and investors, contractors, and consultants often come from different parts of the world. This necessitated a common set of standards and practices to ensure consistency, transparency, and fairness in the construction industry on a global scale.

The Role of International Standards 

International standards in quantity surveying are a set of guidelines and best practices designed to standardize processes, terminology, and reporting across borders. These standards facilitate communication and collaboration among professionals, organizations, and countries involved in construction projects worldwide.

Several key international standards and organizations contribute to this harmonization:

1. RICS (Royal Institution of Chartered Surveyors): RICS, a renowned professional body, offers global standards for quantity surveying and construction professionals. These standards encompass ethical behavior, measurement, and property management, among others. They serve as a reference point for practitioners around the world.

2. ISO (International Organization for Standardization): ISO develops and publishes international standards for various industries, including construction. ISO standards in quantity surveying cover topics such as building information modeling (BIM), construction project management, and sustainability. These standards help ensure uniformity in processes and facilitate cross-border collaboration. 

3. CIC (Construction Industry Council): The CIC, based in the UK, provides a platform for international collaboration in the construction industry. It fosters the exchange of knowledge and best practices among professionals from different countries, promoting the use of standardized approaches to quantity surveying.

Global Guidelines for Quantity Surveying Excellence

International standards in quantity surveying serve as a common language for professionals around the world. They promote consistency and ensure that all parties involved in a construction project have a shared understanding of processes and procedures. Let's explore some key areas where international standards have made a significant impact:

Measurement Standards

Measurement is at the heart of quantity surveying. Accurate measurements are essential for cost estimation and control. The International Construction Measurement Standards (ICMS), developed by a coalition of organizations, including RICS, provides a global framework for the consistent measurement of construction projects. ICMS helps in comparing construction costs across different regions and ensures that clients and stakeholders have a clear understanding of what they are paying for.

Cost Estimation and Classification 

International standards also address cost estimation and classification. The New Rules of Measurement (NRM), published by RICS, offers a comprehensive set of rules for measuring and classifying construction works. These rules provide a common basis for preparing bills of quantities and cost estimates, which is crucial for fair and accurate pricing of construction projects.

Contract Forms

Contracts are the backbone of construction projects, and international standards play a crucial role in standardizing contract forms. For instance, the FIDIC (International Federation of Consulting Engineers) suite of contracts is widely recognized and used in international construction projects. These contracts are designed to balance the interests of all parties involved, ensuring that projects are completed successfully and disputes are minimized.

Ethics and Professionalism

Ethical standards are fundamental in maintaining the integrity of the quantity surveying profession. International organizations like RICS have established codes of ethics that guide professionals in their conduct. These codes emphasize honesty, integrity, and transparency, which are essential values in a globalized and diverse industry.
