Introduction
Quantity Surveyors (QS) play a crucial role in the success of construction projects, especially for developers aiming to keep costs under control while maintaining quality and compliance. Understanding what a QS does and how they add value can make a significant difference to your project’s bottom line.
What Does a Quantity Surveyor Do?
A QS is responsible for managing all costs relating to building and civil engineering projects, from initial estimates to final figures. Their key tasks include:
Preparing cost plans and budgets
Advising on procurement strategies
Managing tender processes and contractor selection
Monitoring project costs and variations
Ensuring value for money throughout the project
Why Involve a QS Early?
Engaging a QS at the earliest possible stage allows developers to:
Accurately forecast project costs
Identify potential risks before they become issues
Optimise design for cost-effectiveness
Set realistic budgets and timelines
Key Stages Where a QS Adds Value
Pre-construction: Budgeting, feasibility studies, and procurement planning
Tendering: Preparing and evaluating tenders, contractor negotiations
Construction: Cost control, progress valuations, and managing variations
Post-construction: Final account preparation and cost reporting
How to Choose the Right QS
Look for experience in your sector or project type
Check for relevant qualifications and professional memberships (e.g., SCSI, RICS)
Ask for references or case studies
Ensure clear communication and transparency
Conclusion
A skilled QS is an essential partner for developers in Ireland, providing expert guidance at every stage of the construction process. By involving a QS from the outset, you can protect your investment, avoid costly surprises, and deliver successful projects on time and within budget.
