Embarking on a career as a quantity surveyor offers diverse opportunities, but one of the first major decisions you’ll face is whether to pursue the path of a Consultant Quantity Surveyor (PQS) or a Contractor Quantity Surveyor (CQS). Both roles are integral to the construction industry, yet they differ significantly in their focus, responsibilities, and career trajectories. Here’s a detailed comparison to help you decide which route aligns with your goals and aspirations.
The Role of a Consultant Quantity Surveyor (PQS)
A Consultant Quantity Surveyor typically works for a consultancy firm or as an independent advisor. Their primary role is to represent the client’s interests throughout the lifecycle of a construction project.
Key Responsibilities:

Tender Management: Preparing tender documents, evaluating bids, and advising clients on contractor selection.
Contract Administration: Managing contracts, including handling variations and claims.

Variety of Projects: Opportunity to work across a wide range of projects and sectors.
Client Interaction: Regular engagement with clients and other stakeholders.
Strategic Focus: Emphasis on planning, budgeting, and advising.
Professional Development: Greater exposure to professional services and industry standards.
Challenges of Being a PQS:
Pressure to Satisfy Clients: High expectations from clients can lead to intense pressure.
Limited Site Presence: Less direct involvement with on-site activities compared to a CQS.
The Role of a Contractor Quantity Surveyor (CQS)
A Contractor Quantity Surveyor works for a contractor or subcontractor, focusing on the delivery and profitability of construction projects.
Key Responsibilities:
Cost Control: Monitoring and controlling project costs to ensure profitability.
Subcontractor Management: Procuring subcontractors and managing their accounts.
Valuations and Payments: Preparing interim valuations and securing payments from clients.
Variation and Claims: Identifying, pricing, and negotiating variations and claims.

Hands-On Experience: Direct involvement in the construction process.
Fast-Paced Environment: Dynamic and fast-moving work environment.
Career Progression: Opportunities to advance into project management or commercial leadership roles.
Tangible Results: Satisfaction from seeing projects come to life.
Challenges of Being a CQS:
Long Hours: Project deadlines and site demands can result in extended working hours.
Profit Pressure: Responsibility for project profitability can be stressful.
Key Differences Between PQS and CQS

Which Route Should You Choose?
The decision between becoming a PQS or CQS depends on your career aspirations, interests, and preferred working style. Here are some questions to consider:
Do you enjoy strategic planning and advising clients? If so, the PQS route might be for you.
Are you energized by fast-paced, hands-on work environments? If yes, a career as a CQS could be more suitable.
Do you prefer variety in projects or direct involvement in construction? PQS roles often offer more variety, while CQS roles provide direct site experience.
How do you handle pressure? Both roles come with challenges, but the type of pressure differs. PQS roles involve client expectations, while CQS roles focus on profitability and deadlines.
Conclusion
Both Consultant QS and Contractor QS roles offer fulfilling career paths with unique challenges and rewards.
