Frequently Asked Questions

A quantity surveyor (QS) is a highly skilled professional responsible for managing all aspects of the costs and financial aspects of a construction project. QS’s are involved from the initial planning and design stages through to the final construction and post-construction phases.

Their core responsibilities include:

1. Cost Estimation: QS carefully estimate costs, calculate material needs, and map out project timelines.
2. Client Consultation: They consult with clients to understand their requirements.
3. Feasibility Studies: QSs conduct feasibility studies to vet proposed projects.
4. Budgeting and Cost Control: They prepare tender packages, manage risk, and control costs efficiently.
5. Contract Administration: QSs negotiate contracts, oversee subcontractors’ work, and ensure compliance with regulations and quality standards.
6. Reporting and Analysis: They provide budget and progress reports, analyze outcomes, and advise on claims and disputes.

Whether representing the construction firm or working directly for the client, QSs play a crucial role in ensuring successful project outcomes

The average cost of the design team for a project would be as follows; but it will all depend on the project itself.

1. Architect 5-7%
2. QS 2-4%
3. Structural Engineer 2-4%
4. M & E Design 2-4%

All projects are different but to give you an approximate guide on how long some projects should take.

1. Small extension to the rear of your house, assumed under 40m2; 2 – 4 months.
2. Small renovation to a typical 3 or 4 bed house; 3 – 6 months.
3. Full renovation and extension of a typical 3 or 4 bed house; 6 – 9 months.
4. New 4 bed detached house on a greenfield site; 9-12 months.
5. Anything more than this like big buildings, apartment blocks, public buildings etc would need to be assessed on an individual basis.

All construction projects are different and need to be assessed on an individual basis as there are so many different elements all coming together but to give you a guide, here is what a simple project might look like.

1. Buy the Building / house or land.
2. Engage an Architect to complete the new design. (Go for planning permission if required).
3. Engage a QS to give an overview on the potential costings.
4. Engage the full design team, i.e. Structural Engineer, Mechanical & Electrical Engineers, Interior Designers, Landscape Architects, Lighting Designers, Subcontractors, as required for the project.
5. Complete the full design and go out to tender to receive quotes back from main contractors.
6. Tender analysis and appoint the builder/contractor.
7. Sign contracts and start construction on site.
8. Complete monthly site meetings and valuations as you work through the project.
9. Complete the full project and agree on the final account.
10. Complete Snag Lists, Retention and Sign Off by the team
