Why Choose Coval Quantity Surveyors
At Coval, we don’t just provide estimating, we deliver the commercial insight that helps you win more work, reduce risk, and protect your margins.
The Coval Difference
Coval stands out as a commercially intelligent, relationship-focused consultancy that offers far more than just spreadsheets. We are confident that our unique selling points clearly set us apart from other construction estimating companies.
1. Practical Site Experience. Not Office-Based Estimating
Unlike many estimators who work solely from an academic or desk-based background, Coval brings 10 years of on-site experience in engineering and site management. This means tenders are built with an understanding of real-world logistics, sequencing, and buildability — reducing risk and increasing accuracy.
2. End-to-End Expertise with Over 25 Years’ Experience
Coval blends 15 years of specialist estimating and consultancy with deep civil engineering experience, offering a comprehensive and well-rounded service that’s technically sound and commercially astute.
3. Turnkey Tender Support
Many estimating services offer just take-offs or limited support — Coval provides full-cycle tender estimating, from documentation review and BoQs to subcontractor engagement, risk registers, and post-tender adjustments.
4. High Client Retention (90% Return Rate)
Coval’s client relationships aren’t transactional — they’re trusted partnerships. With a 90% return rate, and the remaining 10% re-approaching for more work (only limited by capacity), Coval’s service speaks for itself.
5. Flexible, Remote, and Scalable Support
Coval offers remote estimating on a per-project basis, meaning no long-term contracts or overheads — just targeted, expert support when you need it.
6. Trade-Focused Approach
With structured trade package estimating services and the use of client-preferred or vetted supply chains, Coval offers a more tailored and collaborative approach than generic estimating consultancies.
